Answer

b. No

Step-by-step explanation:

We can easily solve this question by using a graphing calculator or any plotting tool, to check if it is a sinusoid.

The function is

f(x) =  sin(20*x) + cos(8*x)

Which can be seen in the picture below

We can notice that f(x) is a not sinusoid. It has periodic amplitudes, and the function has a period T = π/2

The maximum and minimum values are

Max = 1.834

Min = -2

Megan hiked 15.12 miles in 6.3 hours if Megan hiked the same number of miles each hour how many miles did she hike each other
notsponge [240]

Total hours of hiking is 15.12 miles

Time taken is 6.3 hours

The number of miles hiked per hour would be

Total hours ÷ time taken

\frac{15.12}{6.3}

=2.4 miles

So Megan has hiked 2.4 miles every hour
