IceJOKER [234]

Answer:

The generator will run for 6 hours.

Step-by-step explanation:

First, find the volume of the gas tank that is on the generator. I am told that the gas tank is a rectangular prism that has the dimensions of 20 cm, 15 cm, and 10cm.

Area of any prism = height * width * length

Area of prism = 20 cm * 15 cm * 10 cm = 3,000 cm cubed

I am told the important info that <u>1,000 cm cubed = 1 liter </u>

Therefore, 3,000 cm cubed = 3 liters

I am also told that the generator will run for 2 hours on 1 liter of gas

Lets make a ratio table:

Hours the generator will run for : liters of gas

                                                   2 : 1

                                                   6 : 3

the generator will run for 6 hours.

Evaluate the function.<br> f(x) = 3x2 + 16<br> Find f(-1)
SIZIF [17.4K]

Answer:

f(-1)=19

Step-by-step explanation:

<u>Evaluating Functions</u>

Given a function y=f(x), evaluate the function for x=a means substituting the variable for the given value.

We have the function:

f(x)=3x^2+16

Find f(-1):

f(-1)=3(-1)^2+16

f(-1)=3(1)+16

f(-1)=3+16

\boxed{f(-1)=19}
