Answer:

The answer to your question is t = 1.3 s

Step-by-step explanation:

Data

Equation    h(t) = -4.9t² + v₀t + h₀

v₀ = 0 m/s

h₀ = 8 m

t = ?

h = 0 m

Process

1.- Substitute the values in the formula

                  0 = -4.9t² + 0t + 8

2.- Simplification

                  0 = -4.9t² + 8

3.- Solve for t

                 4.9t² = 8

                      t² = 8/4.9

                      t² = 1.63

4.- Result

                      t = 1.27 ≈ 1.3 s

Answer:

figure skates will be $1 cheaper.

Explanation:

<u>given equation</u>:

  • to rent figure skates : f(x) = 1.50x + 2
  • to rent hockey skates : h(x) = 2x +1.5

<u>solve for rent of figure skates</u>:

f(x) = 1.50x + 2.00

f(3) = 1.50(3) + 2.00

f(3) = 6.5

<u>solve for rent of hockey skates</u>:

h(x) = 2x + 1.5

h(3) = 2(3) +1.5

h(3) = 7.5

<u>cheaper - figure skates than hockey skates</u>:

$7.5 - $6.5

$1
