Answer: 0.512
Step-by-step explanation:
256/32=8
8*(0.4)^3=
8*0.064=0.512
y=0.512
Answer:
Exponential
Step-by-step explanation:
Sent a picture of the solution to the problem (s). I set it up as a proportion to solve.
For this case we have the following quadratic equation:

By the time the projectile hits the ground we have the final height equal to zero:

Therefore, we have a second-order polynomial that we must solve:
Using resolver we have:

Rewriting:

Doing the calculations we have two roots:

We discard the negative root because we are looking for time which is greater than zero.
Answer:
the projectile will hit the ground after:
C. 5.3 seconds
Answer:
a. square
b. square
c. The shapes are the same because they are in the same form and are similar. They are different because they have different dimensions.
