Answer:
A and D
Step-by-step explanation:
To solve this you need to know Pythagorean theorem.
First, EG is 24, so the halfway points are 12. Knowing Pythagorean triples, you can use 5,12,13 and 12,16,20.
DF = 5+16
DF = 21
If you don't know Pythagorean triples, I have worked it out on the image attached.
Rent for 6 hours = 21
rent for a hour = 21/6
= $3.5
∫ √(4x - x²) dx
= 2[(4x - x²)^(3/2)] / 3(4 - 2x)
Answer:
Correct, as 4 is the only number repeating twice
