Elodia [21]

Answer:

$y(t) = 166 - 24t$

Step-by-step explanation:

Given

$v =24$ --- velocity to safe zone

$t = 4$ --- after safe zone

$d_1 = 70$ --- distance from safe zone

Required

Represent as a function

Calculate distance (d) from the safe zone

$d_2 = velocity * time$

$d_2 = 24 * 4$

$d_2 = 96$

From the question, we understand that she is 70 m from zone.

This implies that her current distance is:

$d = d_1 + d_2$

$d = 70 + 96$

$d = 166$

So, the function is:

$y(t) = d - v * t$

$y(t) = 166 - 24 * t$

$y(t) = 166 - 24t$

Answer:

see explanation

Step-by-step explanation:

To express a fraction in simplest form

Divide numerator and denominator by largest common factor of both

$\frac{6}{12}$ ← divide by 6

= $\frac{1}{2}$ ← in simplest form

$\frac{12}{15}$ ← divide by 3

= $\frac{4}{5}$ ← in simplest form
