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)
Answer: 17873.75 dollars
Step-by-step explanation:
We can use the equation: l = p x r x t (Total Interest = principal x interest rate x years/time)
9050 will be the principal; it's the amount you deposit in the first place.
7.5% is the interest rate. You can convert it to 0.075 as a decimal.
13 is the years/time. If Marcus's parents put the college fund in when he was 5 and now he's 18, there has been 13 years in between.
9050 x 0.075 x 13 = 8823.75
8823.75 + 9050 = $17873.75
So in Conclusion, the total amount in the account when Marcus is 18 is 17873.75 dollars.
Hope this helps!

16.87 plus 8.79 equals $25.66
Answer: y=-3/4x
Step by step explanation:
y-y_0=m(x-x_0)
y+3=-3/4(x-4)
y=-3/4x+3-3
y=-3/4x
m=rise/run
m=-3/4
Answer:
1/3
Step-by-step explanation:
2/5+2/5-7/15
=2+2/5 -7/15
=4/5-7/15
=4×3-7/15
=12-7/15
=5/15
=1/3 Ans.
