Answer:
(-8, ∞)
Step-by-step explanation:
The coefficient of x^2 is negative so the graph rises from the left until x = -8 and y = -1.
So it decreases from x = -8 to x = infinity.
Answer: It costs $6 to drive 30 miles.
Step-by-step explanation:
$4 per 20 miles
20/4 = 5
1$ per 5 miles
30/5 = 6
6 * 5 = 30
You will need the formula for finding the volume of a rectangular prism (cuboid).
V = l x w x h
1. V = x^2 x h
2. To solve for x, you will substitute in the information you know.
150 = x^2 x 24
Divide both sides by 24 to get
6.25= x^2
The square root of 6.25 is 2.5.
x = 2.5 cm
