A student claims that 8^3 • 8^-5 is greater than 1. Explain wheather the student is correct or not.
xxTIMURxx [149]

The student is right. Because when multiplying both numbers, we have to multipy the exponents together. And in this case we are going to get 8^-15. And when it is simplified, it is actually bigger than 1.

When Joey dives off a diving board, the equation of his pathway can be modeled by h = -16t2 + 15t + 12. A) Find Joey's maximum h
sergeinik [125]

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
