To estimate the total cost, I would say that it is roughly $2 per gallon, and she is buying roughly 9 gallons, so the total cost ≈ 2 x 9 = $18.
Answer: 15 feet
Step-by-step explanation:
From the question, we are informed that a diving board is 10 feet above a pool. Since the ladder is 5 feet away from the base of the diving board, to calculate how tall is the ladder is, we subtract -5 from 10. This will be:
= 10 - (-5)
= 10 + 5
= 15 feet
The answer is option C.
Answer:
-1
Step-by-step explanation:
The given function, f(x), has three distinct parts. We must find and choose the part whose domain includes x = 1.
This x = 1 is a member of the set 1 ≤ x < 2. Therefore, we choose the 2nd part of this function: evaluate -x^2 at x = 1. This comes out to -1^2, or -1. that's the second answer choice.
