A water balloon is launched from a slingshot with an initial velocity of 64 f/sec. The height with respect to time can be modeled by the function h(t)=64-16t^2 where t is time in seconds

1)(0.75,55)

2)(1.5,28)

3)(2,0)

(2.25,-17)

(3,-80)

(4,-192)

Step-by-step explanation:

1) substitute "t" values in table into the equation:

64-16(0.75)^2=

55

64-16(1.5)^2=

28

64-16(2)^2=

0

64-16(2.25)^2=

-17(ball already reached ground and went underground)

64-16(3)^2=

-80

64-16(4)^2=

-192

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

the answer is b
