She went 3.5 feet per second down for 90 seconds
3.5*90 = 315 feet below
2.2*30 = 66 feet up
315-66 = 249 feet below.

So, she must go up at 4.8 feet per second.
249/4.8 = 51.875 seconds
52 seconds when rounded

ANSWER QUICK PLEASE<br> If f(x) = |x – 5| + 3, find f(2).
Ivanshal [37]

Answer:

SO if f(x)= |x-5|+3 then F(2)= 6

Step-by-step explanation:

These signs |  | mean that it is an absolute value equation. SO that means any negative will automatically change to positive values and positive values will stay at positive values. You are supposed to substitute 2 in for x and if you do 2-5 then that is negative 3 but it changes to positive 3 and add three and then f(2)= 6

A building is 200ft long and 140 ft wide a 1/500 model is built of the building how long and how wide is the model?
Katena32 [7]
Let's start with the length. All you need to do is multiply is by 1/500.
You could also find the decimal equivalent to 1/500.
1/500= .002
200×.002= .4
So length of the model is .4 ft.
The width:
.002×140=.28
The width of the model is .28 ft.
The length of the model is .4 ft and the width of the model is .28 ft.

The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28.
natta225 [31]

we have

2x-2y=6 ------> equation 1

4x+4y=28 ------> equation 2

Multiply by 2 the equation 1

4x-4y=12 ------> equation 3

Sum equation 2 and equation 3

4x+4y=28\\ 4x-4y=12\\ ------\\ 8x=40\\ x=40/8\\ x=5

Substitute the value of x in the equation 2

4x+4y=28

4*5+4y=28\\ 4y=28-20\\ 4y=8\\ y=8/4\\y=2

therefore

the answer is the option B

(5,2)

If f(x) = 4x-3, which of the following is the inverse of f(x)?
GalinKa [24]

Answer:

\huge\boxed{f^{-1}(x)=\dfrac{x+3}{4}=\dfrac{1}{4}x+\dfrac{3}{4}}

Step-by-step explanation:

f(x)=4x-3\to y=4x-3\\\\\text{exchange}\ x\ \text{to}\ y\ \text{and vice versa}\\\\x=4y-3\\\\\text{solve for}\ y\\\\4y-3=x\qquad|\text{add 3 to both sides}\\\\4y-3+3=x+3\\\\4y=x+3\qquad|\text{divide both sides by 4}\\\\\dfrac{4y}{4}=\dfrac{x+3}{4}\\\\y=\dfrac{x+3}{4}\to y=\dfrac{1}{4}x+\dfrac{3}{4}
