Luke drives to his grandmother's house on Saturday. The first three hours he drives 50 miles per hour. The next three hours, Luke stops to eat and buy his grandmother a birthday present. The
next four hours, Luke drives 60 miles per hour.
Write a function d(t) for his distance in miles from home in terms of the time (1) in hours.
b) Draw a graph of his distance from home versus the time.
c) Find d(2.3) and explain the meaning of the answer.
d) Find the value of t when d(1) = 322 and explain the meaning of the answer.
Graph y = x
b)
a)
Write the function as a piecewise function.
Graph y = |x-2).
Write the function as a piecewise function,
b)
It

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
