Answer:
39 feet
Step-by-step explanation:
The equation of the path of the book is an upside down parabola.
We can find the x-coordinate of the vertical axis.
The x-coordinate of the maximum point is
x = -b/2a
for a parabola written in the following form
f(x) = ax² + bx + c
We have -16t² + 24t + 30, so we have
a = -16
b = 24
c = 30
t = -b/2a = -24/(2 × (-16)) = -24/(-32) = 0.75
The maximum height occurs at time = 0.75 seconds.
Now we plug in the time into the equation to find the maximum height.
h(x) = -16t² + 24t + 30
h(0.75) = -16(0.75)² + 24(0.75) + 30
h(0.75) = -9 + 18 + 30
h(0.75) = 39

round these amounts to the nearest whole dollar.3.87cedis.9.28 cedis.11.05 cedis.4.39cedis
Answer: 4.00, 9.00, 11.00, 4.00
Step-by-step explanation:
When we round, we round from the digit one smaller than the one we're rounding to. In this case, since we're rounding to the dollar, we round from the 10th place. To round, we need to know whether the number we're rounding from is smaller than, equal to, or larger than 5. If the number is smaller than 5, we round down. Larger, and we round up. If the number is equal to 5, we also round up.
Find the value of x.
Answer:
35°
Step-by-step explanation:
There are 4 angles in quadrilateral which is equal to 360°. So...Add 100°, 110° and 80° and you will get 290°. Then, substract 290° from 360°. So you will get 70° which is Angle B. and then there's a straight line crossing the angle B. So divide with 2. You will get 35° which is equal to angle x because of the straight line.

Which of the following is NOT a linear function?
Answer:
x^2 + 8 = 64 is not a linear function
Step-by-step explanation:
using the process of elimination and a graphing calculator, you can see that the rest of the functions give you a linear function. therefore, the answer is x^2 + 8 = 64 is not a linear function!! i hope this helps you!! <3
The [tex]x^2 + 8 = 64[/tex] is not the liner function.
The following information regarding the linear function is:
It is the function where the graph is in the straight line. The form in the linear function should be y = a + bx.In this, there is one dependent and one independent variable.Therefore we can conclude that the [tex]x^2 + 8 = 64[/tex] is not the liner function.

This is really confusing
Step-by-step explanation:
The 53rd ball will be blue. I don't really know how to explain but I'll try.
So there are black, white and blue balls. If you look closer you'll see that the words 'black,white,blue,black, blue were repeated twice. So let's say that the first 5 letters are a set. To get the 50th color, all you have to do is 5 × 10 which is 50 and the 50th term is blue. Just add black(51st), white(52nd) and you'll get the 53rd color to be Blue.

Divide: 5 by 1 / 4
please
Answer:
20
Step-by-step explanation:
Make 5 a fraction which would be 5/1
Then make an expression, "5/1 / 1/4"
Then switch and flip meaning make the division sign a multiplication sign and make 1/4 into 4/1.
Your expression should look like 5/1 x 4/1
Then multiply 5 and 4 and you get 20. You do not need to write it as a fraction.

Write and equation to represent the function.
Input(x). 1. 2. 3. 4
Output(y). 8. 19. 30. 41
Answer:
[tex]y=11x-3[/tex]
Step-by-step explanation:
Given ordered pairs:
(1, 8) (2, 19) (3, 30) (4, 41)
As the y is directly proportional to x (y values increase +11 for every +1 increase for the x-values) then the equation will be linear.
Point-slope form of a linear equation: [tex]y-y_1=m(x-x_1)[/tex]
(where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex] is a point on the line)
[tex]\textsf{slope }m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Let:
[tex](x_1,y_1)=(1,8)[/tex][tex](x_1,y_2)=(2,19)[/tex][tex]\implies \textsf{slope }m=\dfrac{19-8}{2-1}=11[/tex]
Using point-slope equation with m = 11 and point (1, 8):
[tex]y-y_1=m(x-x_1)[/tex]
[tex]\implies y-8=11(x-1)[/tex]
[tex]\implies y=11x-3[/tex]
Write an inequality that represents the graph.
Answer:
y ≤ -x - 2
Step-by-step explanation:
the line is going down (negative slope) so that's why u have the negative it translated 2 units DOWN on the yaxis so that's why there is - 2 the line is SOLID so it's going to have the equal sign under it, if the line was dashed it would just be a regular sign fr example (<)the shading is BELOW the line so that means it's going to be LESS THAN OR EQUAL TO !!The inequality that represents the graph is y ≤ -x - 2
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
from the given graph, we get,
1. the line is going down (negative slope) so that's why u have the negative
2. it translated 2 units DOWN on the yaxis so that's why there is - 2
3. the line is SOLID so it's going to have the equal sign under it, if the line was dashed it would just be a regular sign fr example (<)
4. the shading is BELOW the line so that means it's going to be LESS THAN OR EQUAL TO !!

At Gulfport Electronics, Randy earns a monthly salary of $1500 plus a 5% commission of x, his total monthly sales. If his March earnings total $2500, write and solve an equation that could be used to determine his total monthly sales for the month of March
Answer:
His March Earnings is $20000
Step-by-step explanation:
Given
[tex]Salary = \$1500[/tex]
[tex]Commission = 5\%\ of\ sales[/tex]
[tex]March\ Earnings = \$2500[/tex]
Required
Determine the monthly sales
Represent the monthly sales with x
The march earnings can be determined using:
[tex]March\ Earnings = Salary + Commission[/tex]
[tex]March\ Earnings = Salary + 5\%\ of\ x[/tex]
Substitute values of March Earnings and Salary
[tex]2500 = 1500 + 5\% * x[/tex]
[tex]2500 = 1500 + 0.05 * x[/tex]
[tex]2500 = 1500 + 0.05x[/tex]
Solve for 0.05x
[tex]0.05x = 2500 - 1500[/tex]
[tex]0.05x = 1000[/tex]
Solve for x
[tex]x = 1000/0.05[/tex]
[tex]x = 20000[/tex]
Hence:
His March Earnings is $20000

Answer:
12 edges, 6 faces, and 7 vertices.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
I say 12 edges because there are 12 meeting points, and an open shape.
6 faces because there are 6 highlighted points on what looks like an unfolded shape.
8 vertices because you add 2 to the number of edges and subtract by the number of faces, 6.
What is the slope of the line that passes through the points (-4, -2) and (-4, -22)? Write your answer in simplest form.
Answer:
Your answer is: Undefined
Use the slope formula to find the slope m .
Step-by-step explanation:
Hope this helped : )
The slope of the line that passes through the points (-4, -2) and (-4, -22) is an infinite slope.
The slope of a line can be found using the formula below.
m = y₂ - y₁ / x₂ - x₁Therefore,
x₁ = -4
x₂ = - 4
y₁ = -2
y₂ = -22
Therefore,
m = -22 - (-2) / - 4 - (-4)
m = -22 + 2 / - 4 + 4
m = 20 / 0
m = infinity
The slope is an infinite slope.

Estimate the x-value of a local maximum shown in the polynomial graphed below. (Enter the estimated x-value as a decimal.)
Answer:
Local Min: (-1.9, 5.1)
Local Max: (0.5, -1.8)
Step-by-step explanation:
The local min and max are mins and maxes relative to the surrounding points. We see that our local min would happen around x ≈ 0.5 and our local max will happen at x ≈ -1.9.
