Answer:
a) 15.52ft
b) 0.47 secs
Step-by-step explanation:
h = -16t^2 + 15t + 12
The maximum height is reached after -b/2a seconds
a = -16 , b = 15, c= 12
-b/2a = -15/2(-16)
= -15/-32
= 0.47 secs
The maximum height = -16(0.47)^2 + 15(0.47) + 12
= -3.5344 + 7.05 + 12
= 15.5156
= 15.52ft

X = 3.879 Y = 2.943
Step-by-step explanation:
I entered both functions into my graphing calculator and graphed them. Then, I clicked 2nd Calc to find the intersection point to which it said the answer above. Hope this helped.
For now I don't know the answer to this problem of yours.
To find the interest accrued for the month, you will use the interest formula I = prt. P stands for the principal (the amount of money borrowed), r is the interest rate, and t is the time period. Because the interest rate is an annual (yearly) interest rate, you will use the fraction 1/12 in your calculation. The math would be $500 x 0.2899 x 1/12. This equals an interest charge of $12.08.
The answer is -7 because you subtract the opposite of 8 and -6-8 is adding two negatives then -14 divides by 2 equals -7 which equals x (-7=x)
