A timer is started and a few moments later a swimmer dives into the water and then comes back up. The swimmer's depth (in feet) as
a function of time (in seconds after the timer was started) is given by the equation h(x) = ² - 14t+40.

Rewrite the formula in factored form and select each true statement below.
The swimmer dives to a depth of 14 feet.
The swimmer dives into the water 4 seconds after the timer was started.
The swimmer dives to a depth of 40 feet.
The swimmer comes back up 10 seconds after the timer was started.
The swimmer comes back up 40 seconds after the timer was started.

The true statement about the equations include:

  • The swimmer dives to a depth of 14 feet.
  • The swimmer comes back up 10 seconds after the timer was started.

How to solve the equation?

The equation given is h(t) = t² - 14t + 40. We'll factorize to get the value of t. This will be:

= t² - 14t + 40

= t² - 10t - 4t + 40

= t(t - 10) - 4(t - 10)

(t - 10) = 0.

t = 0 + 10

t = 10

In this case, the swimmer dives to a depth of 14 feet and then comes back up 10 seconds after the timer was started.
