Answer:
46.57
Step-by-step explanation:
Given that:
h(t) = 37t - 4.9t²
When the ball reaches the ground, then the height is zero;
So, we equate h(t) to zero and solve for t
37t - 4.9t² = 0
t = 0, 7.55
Let the Initial time be a = t = 0
The time the ball reaches the ground be b = 7.55
So, the average height can now be calculated as:
Average height = 
= 
= 
= 
= 46.57091665
≅ 46.57 to (2 decimal places)

<u> 30a² </u> <u> 42a³ </u> <u> 54a³b </u>
2 · 3 · 5 ·× a · a<u /> 2 · 3 · 7 · a · a · a 2 · 3 · 3 · 3 · a · a · a · b
GCF = 2 · 3 · a · a
GCF = 6a² <u />
Answer:
The number is 385.
Step-by-step explanation:
The 5 is in the ones place so you put that at the end. The digit in the tens place is 3 plus the digit in the ones place which is 5 so 3 + 5 = 8 so the 8 is in the tens place. The digit in the hundreds place is 2 less than the digit in the ones place which is 5 so 5 - 2 = 3 so the 3 is in the hundreds place
