Answer:
45
Step-by-step explanation:
72 ÷ 8 = 9. Every 9 teachers is [tex]\frac{1}{8}[/tex]. Since there are [tex]\frac{5}{8}[/tex]teachers that are male, 9 x 5 = 45 female teachers, which leaves 25 male as well

rewrite the function f(x)=-3(x+3)^2-13
in the form f(x)=ax^2+bx+c
Answer:
-3x^2-18x-40
Step-by-step explanation:
(x+3)^2: x^2+6x+9
= -3(x^2+6x+9)-13
Expand:
-3(x^2+6x+9): -3x^2-18x-27
= -3x^2-18x-27-13
Final Answer: -3x^2-18x-40
Answer:
-3x^2-18x-40

1. A restaurant supplier services the restaurants in a circular area in such way that the radius r is increasing at the rate of 2 miles per year at the moment when r = 5 miles. How fast is the area increasing?
Answer:
A= π*r²
dA/dt= π*r*dr/dt
dA/dt= π*5*2= 10π km/yr
Using implicit differentiation, it is found that the area is increasing at a rate of 62.8 miles squared per year.
The area of a circle of radius r is given by:
[tex]A = \pi r^2[/tex]
Applying implicit differentiation, the rate of change is given by:
[tex]A = 2r\pi \frac{dr}{dt}[/tex]
In this problem:
Radius increasing at a rate of 2 miles per year, hence [tex]\frac{dr}{dt} = 2[/tex].Moment of a radius of 5 miles, hence [tex]r = 5[/tex].Then:
[tex]A = 2r\pi \frac{dr}{dt}[/tex]
[tex]A = 2(5)\pi(2)[/tex]
[tex]A = 62.8[/tex]
The area is increasing at a rate of 62.8 miles squared per year.

Gary leaves school to go home. He walks 8 blocks north and then 14 blocks east. If Gary could walk in a straight line to the school, what is the exact distance between Gary and the school?
Answer:
16.12 blocks
Step-by-step explanation:
Given that,
Gary walks 8 blocks north and then 14 blocks east.
We need to find the exact distance between Gary and the school. We can find it by using Pythagoras theorem as follows :
[tex]d=\sqrt{8^2+14^2} \\\\=16.12\ \text{blocks}[/tex]
So, the exact distance between Gary and the school is 16.12 blocks.

Answer:
x =53.85
Step-by-step explanation:
Let x be the original price
If the price is 22% of, you will pay 100% -22% = 78%
x * 78% = 42
Change to decimal form
.78x = 42
Divide each side by .78
.78x/.78 = 42/.78
Rounding to the nearest cent
x =53.85

when you get in your car and you start driving, you start at a speed of 0 and then your speed can be anything from 0 to the maximum speed of your car. If you graphed your speed during a trip, you would end up with one continuous curve for your graph. You won't have any breaks in the graph.

Hey girl! It's me again to explain this to you :)
Number 21.) If we start from our y-intercept -2 and move up 2 on our y-axis we get to point (0,0). If we move over 1 space to the right, we are on (1,0), which is the x-intercept.
Slope: 2/1 or just 2
Y-intercept: -2
You didn't ask for this but i'm gonna write it anyways. The equation for this line is y=2x-2
Number 22.) If we start from our y-intercept 2 and move down 2 on your y-axis we get to point (0,0). If we move over 1 space to the right, we are on (1,0), which is the x-intercept.

170 - 59 = 109
109 - 45 = 64
or do
59 + 45 = 104
104 - 170 = 64

suppose we have function defined by :
f(x)= -3x+7
what values of x give f(x) =-17?
Answer:
x = 8
Step-by-step explanation:
if f(x) = -17
then we can type:
- 3 x + 7 = -17
solving for "x", subtract 7 from both sides
- 3 x = - 17 - 7
- 3 x = - 24
divide both sides by -3 to isolate "x"
x = -24 / (-3)
x = 8
