Answer:
0
Step-by-step explanation:
First, you plug -9 into g(x) and you get g(-9) = - 1. After that, you solve f(-1), which you then reach the solution of 0 by solving.
Answer:
A. 2
Step-by-step explanation:
Part 2 of the graph is the only part where the line is decreasing. The rest of the parts are either horizontal or increasing
If Naya is filling up the gas tank in her motorcycle she puts 4.145 gallons of gas in the tank if the gas cost $2.57 per gallon then she spend $10.65
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given,
The cost of one gallon of gas =$2.57
The quantity of gas she puts in the tank = 4.145 gallons
Apply unitary method
Then, the cost of 4.145 gallons of gas = Cost of one gallon of the gas × Quantity of gas
The cost of 4.145 gallons of gas= 2.57×4.145= $10.65
Hence, If Naya is filling up the gas tank in her motorcycle she puts 4.145 gallons of gas in the tank if the gas cost $2.57 per gallon then she spend $10.65

Step-by-step explanation:
Answer:
Amie should have multiplied 54 by 2/3
Step-by-step explanation:
The formula of the volume of a sphere is given by
, where r is the radius of the sphere.
to find the volume of the sphere, we must find 
We know that the formula of a cylinder of height h and radius r is given by
So 
We know that the sphere and the cylinder have the same height. Recall that the height of the sphere of radius r, is the diameter of a circle that passes through the heighest and lowest points of the sphere. Then, h=2r. This means that
From here, we know that 
.
So the volume of the sphere is 
.
So Amie should have multiplied 54 by 2/3.
