Jessica is returning home from a trip. The function d(t)=458-60t models the distance, in miles, that Jessica is from her house t hours after she began returning home. How far is Jessica from her home 5 minutes after she began returning home?

Write the equation in POINT-SLOPE FORM of the line that passes throught (5,9) and has a slope of -7.

For this case we can use the following trigonometric relationship:   cos (45) = x / 125.5  from here, we clear the value of x:   x = 125.5 * cos (45)  rewriting we have:   x = 125.5 * (root (2) / 2)  x = 88.74190104 cm  round to the hundredth:   x = 88.74 cm  answer:   x = 88.74 cm
