Step-by-step explanation:
Answer:
2004 cubic inches
Step-by-step explanation:
Looking at the figure, there seems to be a chunk missing from the front. Since the overall length is 15 inches, and the length near the missing chunk is 12, then the missing length is 3. If that chunk was filled in, this would have been a 17 * 15 * 8 rectangluar prism. That would have been 2040 cubic inches. (120 * 17) However, a 3 by 8 by 3 triangular prism is missing.
1/2(3 * 8 * 3)
1/2(24 * 3)
1/2(72)
36
Now, subtract 36 from 2040.
2040 - 36

Evaluate the piecewise function for the given values of x by
matching the domain values to the range values.
Answers
Answer:
For x = -4f (x) = x + 2
We evaluate the value of x = -4
f (-4) = (-4) + 2
f (-4) = -2
Answer is : f (-4) = -2For x = 4f (x) = -2x + 4
We evaluate the value of x = 4
f (4) = -2 (4) +4
f (4) = -8 + 4
f (4) = -4
Answer is : f (4) = -4For x = 0f (x) = 3x -4
We evaluate the value of x = 0
f (0) = 3 (0) -4
f (0) = 0-4
f (0) = -4
Answer is : f (0) = -4The value of the function at x = 1 is, f(x) = - x - 4 which equals f(1) = - 3.
What is an absolute value function?We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.
In piecewise terms | x | = x for x ≥ 0 and | x | = - x for x < 0.
Similarly, A piecewise function can also be in terms of without modulus.
Given, f(x) = - x - 4 for x < 3.
f(x) = x² - 7, for 3 ≤x < 12.
f(x) = (120/x) + 5, for x ≥ 12.
Now, At x = 1, It satisfies,
f(x) = - x - 4 for x < 3.
Therefore, f(1) = - (-1) - 4.
f(1) = - 3.

What is the maximum height of the ball?
How long is the ball in the air for before it hits the ground?
Answers
Answer:
a) 16 meters ; b) 8 seconds
Step-by-step explanation:
The function can be represent with a parabola whose vertex is its maximum point
for answer the first question we have to find the y of the vertex
first of all we have to find the x
Vertex (x) = -b/2a = -8/-2 = 4
if we substitute t with 4, we can find the y
Vertex (y) = -(4^2) + (8*4) =
= -16 + 32 = 16
so the answer is 16 meters
for answer the second question we have to find where the parabola intercepts the x axis, that means solve the associated equation:
-t^2 + 8t = 0
t^2-8t = 0
t(t-8) = 0
t = 0
t = 8
the parabola intercept the x axis in (0,0) and in (8,0)
if we find the distance between this two points we can answer to the question
8-0 = 8 seconds

The perimeter of a rectangle is 14cm. The length of the rectangle is 4 cm more than twice the width. Find the dimensions of the rectangle.
Answers
Answer:
length = 6 cm
width = 1 cm
Step-by-step explanation:
l = length
w = width
l = 4 + 2w
2(4 + 2w) + 2w = 14
8 + 4w + 2w = 14
8 + 6w = 14
6w = 6
w = 1
find length:
l = 4 + 2(1)
l = 6

A state university has an annual tuition of $12,000. Bradley would like to attend this university and will save money each month for the next 4 years. His grandparents will give him $2,800 for his first year of tuition. Which plan shows the minimum amount of money Bradley must save to have enough money to pay for his first year of tuition?
Answers
Answer:
$767 per month for the next 4 years
Step-by-step explanation
first it’s minus the 2800 they gave him and that’s 9,200 then divided by the amount of months in a year which is 12 you end up with 766.6 but rounded that would be the closest answer and then when you multiply 767x12 it’s 9200 plus the 2800 it’s 12,000 which means it checks out.

Find the sine of angle I

195
Answers
Answer:
sin I = 0.244
Step-by-step explanation:
Given that,
Perpendicular, P = 195
Hypotenuse, H = 796
We need to find the value of [tex]\sin(I)[/tex]. We know that,
[tex]\sin\theta=\dfrac{P}{H}[/tex]
Substitute all the values,
[tex]\sin I=\dfrac{195}{796}\\\\\sin(I)=0.244[/tex]
So, the value of sin(I) is equal to 0.244.

Step-by-step explanation:
The quadratic formula is
[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$.[/tex]
where a is the coefficient of x squared, b is the coefficient of x, and c is a regular number.
Here, we have
a = 1
b = 7
c = 16
Plugging in values, we have
[tex]\frac{-7 +\sqrt{49 - 4(1)(16)}}{2(1)}[/tex]
and
[tex]\frac{-7 -\sqrt{49 - 4(1)(16)}}{2(1)}[/tex]
The first equation solves to an i term, so there is no way that there is an answer.
The second equation is also an i term, meaning there are no solutions to this equation

Answers
Answer:
B ; C; D
Step-by-step explanation:
The slope measures the rate of change in the dependent variable per unit change in the independent variable :
From the options :
Doing 4 pages of homework in 20 minutes :
The number of pages done per minute = slope
Slope = 20 / 4 = 5
To cycle 32 miles in 4 hours:.
Number of miles to cycle per hour to achieve the feat :
Slope = 32 /4 = 8
Buying 10 shirts for $80:
Cost per shirt = slope
Slope = $80 / 10
Slope = 8
Reading 72 pages in 9 hours
Number of pages read per hour :
72 / 9 = 8 pages

Write an equation of the line with a slope of 23and y-intercept of −8.
Answers
If we have a y intercept of -8, that means that the point falls on the y-axis, therefore x = 0. So, we have a point (0, -8) and we have a slope m = 23.
y = mx + b
y = 23x + b
Now, we can plug in the point values x = 0, y = -8
-8 = 0 + b
b = -8
If we plug b back into our original formula, we get:
y = 23x - 8

Answers
Answer:
Pat is right
Step-by-step explanation:
first multiply/divide then add/subtract,
Beth: 20 - 15 = 45 => 5 ≠ 45
Pat: 20 - 15 = 5 => 5 = 5
Answer:
Pat
Step-by-step explanation:
There is only one correct answer. To find it, you must follow the correct order of operations.
There is a subtraction and a multiplication. There are no parentheses.
The rule is that you must do the multiplication before the subtraction.
20 - 5 * 3 =
= 20 - 15
= 5
In order to get Beth's answer, you'd have to do the subtraction first. If there were parentheses like this: (20 - 5) * 3, then you'd do the subtraction first getting 15 * 3 which is 45, but the problem has no parentheses, so the correct answer is 5.
The correct answer is 5, and Pat is correct.
