Answer:
966 feet
Step-by-step explanation:
First, we can see that we have the velocity function given, a base value for the height, and need to figure out the change in height. We also know that velocity is the derivative of position/height. Thus, we can find the integral of the velocity to find an equation for the height.
[tex]\int\limits^1_0 {-34t+291} \, dt\\[/tex]
Use the exponent rule to turn -34t into -17t² and 291 into 291t to get our result as
-17t²+291t + C = height (h)
When t=0, we know that our height (h) is 6, so C = 6, making our equation
-17t²+291t + 6
To find the change between 1 second and 8 seconds, we can plug 1 and 8 in for t, and find the difference between those values, which is
(-17(8)²+291(8) + 6) - ( -17(1)²+291(1) + 6 )
= 1246 - 280
= 966
Note that we did final value (t = 8) - initial value (t=1), not the other way around
The change in height, between 1 second and 8 seconds, is therefore 966 feet

y = −3
y = −2
y = −1
Answer:
y = -2
Step-by-step explanation:
_____________________
If M is the midpoint of AB, find the coordinates of A if M(-3, 5) and B(6, -11)
midpoint= (x, y)
where x=(x1 + x2)/2
y=(y1 + y2)/2
x1=-3, x2=6, y1=5, y2=-11
so x=(-3 + 6)/2= 3/2
y=(5 + -11)/2= (5-11)/2= -6/2= -3
so mid point =(3/2, -3)

Graph a right triangle with the two points forming the hypotenuse. Using the sides, find the distance between the two points in simplest radical form.
(−5,−1) and (−3,−8)
Answer:
[tex]d=\sqrt{53}[/tex]
Step-by-step explanation:
We need to find the distance between two points i.e. (−5,−1) and (−3,−8).
It can be calculated using distance formula as follows :
[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
We have, x₁ = -5, x₂ = -3, y₁ = -1 and y₂ = -8
Put all the values,
[tex]d=\sqrt{(-8-(-1))^2+(-3-(-5))^2}\\\\d=\sqrt{49+4}\\\\d=\sqrt{53}[/tex]
So, the distance between the points is equal to [tex]\sqrt{53}[/tex]

Determine the equation of the circle graphed below.
Answer:
[tex](x - 6)^2 + (y - 2)^2 = 4[/tex]
Step-by-step explanation:
Required
The equation of the circle
The equation of a circle is:
[tex](x - h)^2 + (y - k)^2 = r^2[/tex]
Where:
[tex]Center = (h,k)[/tex]
[tex]radius \to r[/tex]
From the graph, we have
[tex](h,k) = (6,2)[/tex]
[tex]r = 2[/tex]
So:
[tex](x - h)^2 + (y - k)^2 = r^2[/tex] becomes
[tex](x - 6)^2 + (y - 2)^2 = 2^2[/tex]
[tex](x - 6)^2 + (y - 2)^2 = 4[/tex]
Given f(x) = (1/4) -x, evaluate f(-2), f(1), and f(2). Question 3 options: a. 1/16, 4, 16 b. 16, 1/4, 1/16 c. 16, 4, 16 D. 16, 4, 1/16
Answer:
1/16 ;4 ; 16
Step-by-step explanation:
Given that :
f(x) = 1/4^-x
f(-2) = 1/4^-(-2)
f(-2) = (1/4)^2
f(-2) = (1/16)
f(1) = 1/4^-1
f(1) = 1 / (1/4)^1
f(1) = 1 * 4/1 = 4
f(2) = 1/4^-2
f(1) = 1 / (1/4)^2
f(1) = 1 / (1/16)
f(1) = 1 * 16/1 = 16
A little girl counts using the fingers of her left hand as follows:
She starts by calling her thumb 1, the pointer finger 2, middle finger 3, ring finger 4, and pinky finger 5.
Then she reverses direction (on the same left hand), calling the ring finger 6, middle finger 7, pointer finger 8, and thumb 9, after which she calls her pointer finger 10 and so on.
If she continues to count in this manner, on which finger will she stop?
What if the girl counts from 1 to 10
What if the girl counts from 1 to 100
What if the girl counts from 1 to 1000
Answer:
1 to 10 = Pointer Finger
1 to 100 = Ring Finger
1 to 1000 = Ring Finger
Step-by-step explanation:
Every time she counts 10 on her fingers starting from 1 it either lands on her Index Finger or Ring Finger in a pattern of starting first on her index finger for 10 then ending up on her Ring Finger for 20 and 30 the going back to her Index finger for 40 and 50 and so on. Using this you can figure out 100 and 1000.
If the girl counts from 1 to 100, then finger stops at ring finger.
What is the pattern?In mathematics, a pattern is a recurrent arrangement of numbers, forms, colours, and other elements. Any event or object can be related to the Pattern. An arrangement of numbers is referred to as a pattern when it is done in a certain way. Sometimes a pattern is referred to as a series.
Given that, a little girl starts by calling her thumb 1, the pointer finger 2, middle finger 3, ring finger 4, and pinky finger 5.
One complete round is 8 count.
1) The girl counts from 1 to 10
So, 10/8 here, 2 is remainder.
2 means she stops at pointer finger
2) The girl counts from 1 to 100
Here, 100/8
Thus, quotient = 12 and remainder = 4
So, 4 means she stops at ring finger
2) The girl counts from 1 to 1000
Here, 1000/8
Thus, quotient = 125 and remainder = 0
So, 0 means she stops at thumb
Therefore, if the girl counts from 1 to 100, then finger stops at ring finger.

Which expression entered into a graphing calculator will return the probability
that 35 or fewer heads come up when flipping a coin 100 times?
A. binomcdf(35, 100, 0.5)
B. binomcdf(100, 0.5, 35)
C. binomcdf(100, 35, 0.5)
O D. binomcdf(35, 0.5, 100)
Answer:
B. binomcdf(100, 0.5, 35)
Step-by-step explanation:
Binomcdf function:
The binomcdf function has the following syntax:
binomcdf(n,p,a)
In which n is the number of trials, p is the probability of a success in a trial and a is the number of sucesses.
35 or fewer heads come up when flipping a coin 100 times.
100 coins are flipped, which means that n = 100.
Equally as likely to be heads or tails, so p = 0.5
35 or fewer heads, so a = 35.
Then
binomcdf(n,p,a) = binomcdf(100,0.5,35)
The correct answer is given by option B.
This type of member variable may be accessed before any objects of the class have been created.
a. private
b. public
c. inline
d. static
e. None of these
Answer:
d. static
Step-by-step explanation:
This is a question about Java programming.
A class contains information about it's members(objects). Private, public or inline variables must be related to an object, that is, an object has to be created before the variable is acessed.
Static variables, otherwise, may pertain to the class, and not to the object, that is, and thus, the correct answer is given by option d.
Find a polar equation of the conic in terms of r with its focus at the pole. Conic Eccentricity Directrix Parabola e = 1 x = −1
Answer:
Step-by-step explanation:
From the given information:
The Directrix x = - 1
The eccentricity e = 1
Since the Directrix x = - 1, it implies that the directrix appears on the left negative side of the pole and is vertical.
Hence, the conic equation in terms of r is:
[tex]\mathsf{r =\dfrac{ep}{1-e \ cos \ \theta}}[/tex]
From the directrix to the pole, the distance p = 1
So;
[tex]\mathsf{r =\dfrac{1*1}{1-1 \ cos \ \theta}}[/tex]
[tex]\mathbf{r =\dfrac{1}{1- \ cos \ \theta}}[/tex]

What method would be best to use 53=4(x-3)^2-11
Answer:
x = 7 , -1
Step-by-step explanation:
SOLUTION :-
[tex]4(x-3)^2-11 = 53[/tex]
Add 11 to both the sides.[tex]=> 4(x-3)^2-11+11=53+11[/tex]
[tex]=> 4(x-3)^2 = 64[/tex]
Divide both the sides by 4.[tex]=> \frac{4(x-3)^2}{4} = \frac{64}{4}[/tex]
[tex]=> (x-3)^2 = 16[/tex]
Root square both the sides.[tex]=> \sqrt{(x-3)^2} = \sqrt{16}[/tex]
[tex]=> x-3 = +4 \; or -4[/tex]
Here , x will have two values -
1) [tex]x-3 = 4[/tex]
[tex]=> x = 4 + 3 = 7[/tex]
2) [tex]x - 3 = -4[/tex]
[tex]=> x = -4 + 3 = -1[/tex]
VERIFICATION :-
When x = 7 ,
[tex]4(x-3)^2 - 11 = 4(7 - 3)^2 - 11[/tex]
[tex]= 4 \times 4^2 - 11[/tex]
[tex]= 4 \times 16 - 11[/tex]
[tex]= 64 - 11[/tex]
[tex]= 53[/tex]
When x = -1 ,
[tex]4(x-3)^2 - 11 = 4(-1 - 3)^2 - 11[/tex]
[tex]= 4 \times (-4)^2 - 11[/tex]
[tex]= 4 \times 16 - 11[/tex]

What is the equation of the circle?
Answer:
( x - (-1) )^2 + ( y - (-1) )^2 = 3^2
Step-by-step explanation:
The equation of a circle is ( x - h )^2 + ( y - k )^2 = r^2, r is the radius.
(h,k) is the coordinates for the center point.
In this image, it appears K is 3 units away from any point on the circle, making 3 the radius.
Our equation is now ( x - h )^2 + ( y - k )^2 = 3^2
Now, we need to find the coordinate of K; the center point.
K's x is -1 and K's y is also -1.
Our equation is now:
( x - (-1) )^2 + ( y - (-1) )^2 = 3^2

THANK YOU SO MUCH FOR YOUR HELP
Answer:
Step-by-step explanation:
If you have a square of side [tex]l[/tex], its diagonal would be [tex]l\sqrt{2}[/tex], and its area [tex]l^2[/tex]
If the big square has a area of 900, this implies that its side is [tex]\sqrt{900}[/tex], so the two diagonal of squares 2 and 4 added together would be [tex]\sqrt{900}[/tex], therefore one diagonal wold be [tex]\frac{\sqrt{900}}{2}[/tex]. and its side [tex]\frac{\sqrt{900}}{2}\frac{1}{\sqrt{2}}[/tex]. The area (of one square) is [tex](\frac{\sqrt{900}}{2}\frac{1}{\sqrt{2}})^2=\frac{225}{2}[/tex]
finally the two areas combined (squares 2 and 4) would be 225
Answer:
425
Step-by-step explanation:
I used help from the guy above me to find 2 and 4 so look at theirs for those. (Thank You). For 1 and 3. Each one is 1/9 of the big square. So each one is 1/9*900=100 100*2=200. And then we add 225+200=425.

Write a linear equation for the situation below.
A tank contains 20 gallons of gasoline. Two gallons are drained out of the tank every minute.
Answer:
y = -2x + 20
Step-by-step explanation:
Use the linear equation, y = mx + b, where m is the slope and b is the y intercept.
In this situation, the y intercept is 20, since the starting amount of gasoline is 20 gallons.
The slope will be -2, since 2 gallons are drained per minute.
Plug in these values:
y = mx + b
y = -2x + 20
So, the linear equation is y = -2x + 20

Answer:
B and C
Step-by-step explanation:
Required
Select graphs that are dilated by a scale factor greater than 1
For graph A:
Graph A is smaller than the original graph. This indicates dilation with a scale factor less than 1
For graph B:
Graph B is bigger than the original graph and is dilated over (0,0). This indicates dilation with a scale factor greater than 1
For graph C:
Graph C is bigger than the original graph; however, it is not dilated over (0,0). This indicates dilation with a scale factor greater than 1
For graph D:
Graph D is bigger than the original graph; however, it is not only dilated but also flipped over (i.e. rotated).
Hence, b and c is true
