Answer: f(c) = 3.
Step-by-step explanation:
Since f is differentiable on the open interval (1,10), we can apply the Intermediate Value Theorem and Rolle's Theorem to draw some conclusions about the behavior of f on this interval.
I. f has at least 2 zeros.
This statement cannot be determined solely based on the given information. We know that f(2) = -5 and f(9) = -5, which means that f takes on the value of -5 at least twice on the interval (2, 9). However, we cannot conclude that f has at least 2 zeros without additional information. For example, consider the function f(x) = (x - 2)(x - 9), which satisfies the given conditions but has only 2 zeros.
II. The graph of f has at least one horizontal tangent.
This statement is true. Since f(2) = -5 and f(5) = 5, we know that f must cross the x-axis between x = 2 and x = 5. Similarly, since f(5) = 5 and f(9) = -5, we know that f must cross the x-axis between x = 5 and x = 9. Therefore, by the Intermediate Value Theorem, we know that f has at least one zero in the interval (2, 5) and at least one zero in the interval (5, 9). By Rolle's Theorem, we know that between any two zeros of f, there must be a point c where f'(c) = 0, which means that the graph of f has at least one horizontal tangent.
III. For some c, c is greater than 2 but less than 5, f(c) = 3.
This statement is false. We know that f(2) = -5 and f(5) = 5, which means that f takes on all values between -5 and 5 on the interval (2, 5) by the Intermediate Value Theorem. Since the function is continuous on this interval, it must take on all values between its maximum and minimum. Therefore, there is no value of c between 2 and 5 for which f(c) = 3.

URGENT ANSWER QUICKLY PLEASE A manufacturer wants to design a cone-shaped container that has a volume of 175 cubic centimeters. Their old container is shown.
Hence,0.72 rather than to increase the radius to meet their requirements.
What is the cone ?A cone is a three-dimensional geometric form with a plane base and a smooth tapering vertex. A cone is made up of a collection of line segments, half-lines, its lines that connect the apex of the common point at to every point on a base that is in a flat other than the apex.
What is the volume ?A measurement of three-dimensional space is volume. It is frequently expressed quantitatively using US-standard units ,SI-derived units, as well as several imperial Volume and the notion of length are connected.
Let the new radius x and the old radius as r. The formed volume was 175 cubic cm, and the new container height is 5 cm,
V = [tex]\frac{1}{3}\pi r^2h[/tex], where V is the volume, r is the radius, and h is the height, is the formula for a cone volume.
We can construct an equation using the previous volume:
175 = [tex]\frac{1}{3}\pi r^2h[/tex]
the height is same for new and old container , so,:
175 =[tex]\frac{1}{3}\pi r^2*5[/tex]
175 = [tex]\frac{5}{3}\pi r^2[/tex]
By multiplying both sides by (5/3)
[tex]r^2 = \frac{175*3}{5*\pi}[/tex] ≈ 22.3 use [tex]\pi[/tex]=3.14
When both sides are square root
r ≈ 4.72
Therefore, the old container radius is 4.72 cm.
now,We subtract the old radius from the new radius for determine how much the radius must increase to s the new container:
x - r ≈ 4 - 4.72 ≈ -0.72
Because the new radius is lower than the old radius, the outcome is negative.
We would need to reduce the radius by roughly 0.72 cm rather than expand it to satisfy the needs of the new container.

** This is a 2-page document! **
Directions: Find each angle or arc measure.
The measure of arc FE is 27degrees,angle m<B is 112degrees, <GHJ = <GIJ = 73⁰ , m<S = 90 degrees in the given circles
The sum of angle in the triangle DEF is 180 degrees
mFE = <D
Recall that <D+<E+<F = 180⁰
<D+63+90 = 180
<D = 180-153
<D = 27 degrees
Hence the measure of arc FE is 27degrees
6) For this circle geometry, we will use the theorem
The sum of Opposite side of a cyclic quadrilateral is 180 degrees.
A + C = 180
m<A + 101 = 180
m<A = 180-101
m<A = 79degrees
Similarly
B + D = 180
m<B + 68 = 180
m<B = 180-68
m<B = 112degrees
7) The sum of angle in a circle is 360, hence;
arcGJ+68+31+115 = 36p
arcGJ = 360 - 214
arcGJ = 146⁰
Since the angle at the centre is twice angle at the circumference, then;
<GHJ = 1/2 arcGJ
<GHJ = 1/2(146)
<GHJ = 73⁰
<GHJ = <GIJ = 73⁰ (angle in the same segment of the circle are equal)
8) Recall that the sum of Opposite side of a cyclic quadrilateral is 180 degrees.
P + R = 180
57 + <R = 180
m<R = 180-57
m<R = 123degrees
Similarly, m<Q+m<S = 180⁰
Since the triangle in a semi circle is a right angled triangle, hence m<Q = 90 degrees (triangle PQR is a right angled triangle)
m<S = 180 - 90
m<S = 90 degrees

Answer: 96 slices
Step-by-step explanation:
An artist is creating a scale drawing of a mural in the shape of a right triangle she will paint for the city. Her drawing is 8 inches long and has a hypotenuse of 15 inches. If the mural has a hypotenuse of 96 inches, how long is the mural?
Answer:
51.2 inches

You want the length of a mural whose hypotenuse is 96 inches if the scale drawing has a length of 8 inches and a hypotenuse of 15 inches.
RatiosThe ratios of corresponding lengths will be the same:
drawing length / drawing hypotenuse = mural length / mural hypotenuse
8 in / 15 in = mural length / 96 in
SolutionMultiplying the equation by 96 in, we have ...
(96 in)·8/15 = mural length
51.2 in = mural length
The mural is 51.2 inches long.

On a recent quiz, the class mean was 73 with a standard deviation of 3.1. Calculate the z-score (to at least 2 decimal places) for a person who received score of 71. Z-Score: ____Is this unusual? A. Unusual B. Not Unusual
The, a z-score of -0.65 is not unusual
To calculate the z-score, we use the formula:
[tex]z =\frac{ (x - μ)}{σ}[/tex]
where x is the individual score, μ is the mean, and σ is the standard deviation.
Plugging in the values given, we get:
[tex]z= \frac{71-73}{3.1}[/tex]
z = -0.65
Rounding to 2 decimal places, the z-score is -0.65.
To determine if this score is unusual or not, we need to compare it to the normal distribution. A z-score of -0.65 means that the individual's score is 0.65 standard deviations below the mean.
According to the empirical rule, about 68% of the data falls within 1 standard deviation of the mean. Therefore, a z-score of -0.65 is not unusual and falls within the normal range of scores.

Find the common difference of the arithmetic sequence 14 , 16 , 18
Answer:
The common difference is 2.
Answer:
The common difference of the arithmetic sequence 14, 16, 18 is **2**.
In any arithmetic sequence, each term is equal to the previous term plus the common difference. So, the second term is equal to the first term plus the common difference. In this case, the second term, 16, is 2 more than the first term, 14. Therefore, the common difference is 2.
We can also find the common difference by subtracting any two consecutive terms in the sequence. For example, we can subtract the second term from the third term to get 18 - 16 = 2.
The common difference of an arithmetic sequence is always constant. This means that the difference between any two consecutive terms in the sequence will always be the same. In this case, the difference between any two consecutive terms is 2.

construct a 95onfidence interval for the population variance σ2 if a sample of size 25 has standard deviation s = 14. round the answers to two decimal places.
We can say with 95% confidence that the population variance σ2 lies within the interval [155.25, 570.06].
To construct a 95% confidence interval for the population variance σ2, we can use the chi-square distribution.
First, we need to calculate the chi-square values for the upper and lower limits of the confidence interval. We use the formula:
chi-square upper = (n-1)*s^2 / χ^2(α/2, n-1)
chi-square lower = (n-1)*s^2 / χ^2(1-α/2, n-1)
where n is the sample size, s is the sample standard deviation, α is the level of significance (0.05 for 95% confidence interval), and χ^2 is the chi-square distribution function.
Plugging in the values, we get:
chi-square upper = (25-1)*14^2 / χ^2(0.025, 24) = 43.98
chi-square lower = (25-1)*14^2 / χ^2(0.975, 24) = 15.14
Next, we can use these chi-square values to calculate the confidence interval for σ2:
confidence interval = [(n-1)*s^2 / chi-square upper, (n-1)*s^2 / chi-square lower]
Plugging in the values, we get:
confidence interval = [(25-1)*14^2 / 43.98, (25-1)*14^2 / 15.14]
confidence interval = [155.25, 570.06]

How to find the volume of the solid generated by revolving the region bounded by the graph?(a) To find the volume of the solid generated by revolving the region bounded by the graph[tex]x^2=y-2[/tex] and 2y-x-2=0 for 0≤x≤1 about y=3, we can use the method of cylindrical shells:
First, we need to find the limits of integration for the radius of the shells. Since we are revolving around y=3, the distance between y=3 and the curve x^2=y-2 will give us the radius of the shell.
Solving for y in [tex]x^2=y-2[/tex], we get[tex]y=x^2+2.[/tex] Substituting this into 2y-x-2=0, we get [tex]x=2y-2y^2-2.[/tex] So the limits of integration for the radius will be from [tex]3-(x^2+2) to 3-(2y-2y^2-2).[/tex]
Next, we need to find the height of the shells. This is simply the length of the interval of integration for x, which is 0 to 1.
So the volume of the solid is given by the integral:
[tex]V = \int (3-(x^2+2)) - (3-(2y-2y^2-2)) dx[/tex] from x=0 to x=1
Simplifying and evaluating the integral, we get:
V ≈ 12.422 cubic units.
Therefore, the volume of the solid generated by revolving the region bounded by the graph [tex]x^2=y-2[/tex] and [tex]2y-x-2=0[/tex] for 0≤x≤1 about y=3 is approximately 12.422 cubic units.
How to find the work done in stretching the spring from its natural length to a length of 10 in?(b) (i) The work done in stretching the spring from its natural length of 6 in. to a length of 10 in. can be found using the formula:
W =[tex](1/2)k(d2^2 - d1^2)[/tex]
where k is the spring constant, d1 is the initial length, and d2 is the final length.
Given that the force required to stretch the spring from its natural length of 6 in. to a length of 8 in. is 9 lb., we can find the spring constant as follows:
k = F/(d2 - d1) = 9/(8-6) = 4.5 lb/in
So the work done in stretching the spring from its natural length of 6 in. to a length of 10 in. is:
W = [tex](1/2)(4.5)(10^2 - 6^2)[/tex]= 54 lb.-in.
Therefore, the work done in stretching the spring from its natural length to a length of 10 in. is 54 lb.-in.
How to find the work done in stretching the spring from a length of 7 in. to a length of 9 in?(ii) To find the work done in stretching the spring from a length of 7 in. to a length of 9 in., we can use the same formula:
W =[tex](1/2)k(d2^2 - d1^2)[/tex]
Using the same spring constant of 4.5 lb/in, the work done is:
W = [tex](1/2)(4.5)(9^2 - 7^2)[/tex]≈ 13.5 lb.-in.
Therefore, the work done in stretching the spring from a length of 7 in. to a length of 9 in. is approximately 13.5 lb.-in.

A farmer builds a water though to fit in a corner. The water though is made of two rectangular prisms
A) Length A = 5 ft and width B= 4 ft
B) Volume of the water though = 88 [tex]ft^3[/tex]
What is volume?
The space taken up by any three-dimensional solid constitutes a volume, to put it simply. A cube, cuboid, cone, cylinder, or sphere can be one of these solids. Cubic units are used to measure the volume of solids. The volume will be given in cubic metres, for instance, if the dimensions are given in metres.
Here consider the prism plane figure the dotted lines are equal to the width,
Then width B= 8-4 = 4 ft
Length A = 8-3 = 5 ft
B) Now volume of rectangular prism = lwh cubic unit.
Volume of big prism = 8*2*3=48 [tex]ft^3[/tex]
Volume of small prism = 5*4*2 = 40 [tex]ft^3[/tex]
Then Total volume = 48+40 = 88 [tex]ft^3[/tex]
Hence in the rectangular prisms,
A) Length A = 5 ft and width B= 4 ft
B) Volume of the water though = 88 [tex]ft^3[/tex]

Complete the square to re-write the Quadratic function in vertex form
The vertex form of the given quadratic equation is.
y = -5(x + 6)² - 356
How to complete squares?To complete squares we need to use the perfect square trinomial:
(a + b)² = a² + 2ab +b²
Here we can rewrite our quadratic as follows:
y = -5x² - 60x - 176
y = -5*( x² + 12x) - 176
y = -5*( x² + 2*6x) - 176
Now we can add and subtract 6² = 36 then we will get:
y = -5*( x² + 2*6x + 36 - 36) - 176
y = -5*( (x + 6)² - 36) - 176
y = -5(x + 6)² - 356
Which means that the vertex is at (-6, -356)

double integral of x^2 2y bound by y = x, y = x^3, and x> 0
The double integral of x² 2y over the given region (bounded by y = x, y = x³, and x > 0) is 2/35.
How to evaluate the double integral of the x² 2y?To solve this double integral, we need to integrate the function x² 2y over the given region in the xy-plane.
The region is bounded by the curves y = x and y = x³, and the line x = 0.
First, we need to determine the limits of integration. Since x > 0,
we can integrate from x = 0 to x = 1.
For each value of x in this range, the lower bound of y is given by y = x, and the upper bound is given by y = x³.
Therefore, we need to integrate with respect to y from y = x to y = x³ for each value of x in the range [0, 1].
So, the double integral can be written as:
∫(0 to 1) ∫(x to x³) x² 2y dy dx
Integrating with respect to y first, we get:
∫(0 to 1) [x² y²]x³_x dy dx= ∫(0 to 1) (x⁶ - x⁴) dx= [1/7 x⁷ - 1/5 x⁵]0_1= 1/7 - 1/5= 2/35Therefore, the double integral of x² 2y over the given region is 2/35.

At the city museum, child admission is $5.60. and adult admission is $9.40. On wensday, 177 tickets were sold for a total of $1352.20. how many adult tickets were sold that day?
Let's use variables to represent the number of child and adult tickets sold on Wednesday.
Let c be the number of child tickets sold, and let a be the number of adult tickets sold.
We know that the price of a child ticket is $5.60, and the price of an adult ticket is $9.40.
From the problem statement, we know that 177 tickets were sold in total, so:
c + a = 177
We also know that the total revenue from ticket sales was $1352.20, so:
5.60c + 9.40a = 1352.20
Now we have a system of two equations with two variables. We can solve for a by using the first equation to express c in terms of a, and then substituting into the second equation:
c + a = 177 --> c = 177 - a
5.60c + 9.40a = 1352.20
Substituting c = 177 - a into the second equation, we get:
5.60(177 - a) + 9.40a = 1352.20
Expanding and simplifying:
992.20 - 5.60a + 9.40a = 1352.20
3.80a = 360
a = 95
Therefore, 95 adult tickets were sold on Wednesday.
Its bugging out but I got 95 tickets I would add explanation if it didn't act out.
X=Adult tickets
Y=Child tickets
X+Y=117
Y=117-X
9.40X+5.60Y=1352.20
9.40X+5.60(117-X)=1352.20
9.40X+991.20-5.60x=1352.20
3.80X=361
X=95

Step-by-step explanation:
F(1) = 15 f(n)= f(n-1) x n evaluate the sequences in recursive form
Answer:
f(1) = 15
f(n) = f(n-1) x n
Step-by-step explanation:
The sequence in recursive form is:
f(1) = 15
f(n) = f(n-1) x n
Using this recursive formula, we can find the value of any term in the sequence by calculating the value of the previous term and multiplying it by the index of the current term.
For example, to find the value of f(2), we would use the formula:
f(2) = f(1) x 2
f(2) = 15 x 2
f(2) = 30
Similarly, to find the value of f(3), we would use the formula:
f(3) = f(2) x 3
f(3) = 30 x 3
f(3) = 90
And to find the value of f(4), we would use the formula:
f(4) = f(3) x 4
f(4) = 90 x 4
f(4) = 360
We can continue using this formula to find the values of any term in the sequence.
