A sinusoidal function whose frequency is 3, maximum value is 15, minimum value is -3 has a y-intercept of 6.
maxonik [38]

Answer:

A. f(x) = 9sin(x/3) + 6

Step-by-step explanation:

First, we can eliminate B and C because they have the wrong vertical shift.

Since the y intercept is 6, this means the function has a vertical shift up 6 units, represented by a +6 at the end of the equation.

The amplitude is 9, found by calculating the difference between the minimum and maximum values, and dividing it by 2.

(15 - (-3)) / 2

18 / 2

= 9

Using a calculator, find the period given the frequency.

The period (coefficient of x) is 1/3.

So, putting all of these constants together, the correct equation is:

A. f(x) = 9sin(x/3) + 6

A car is traveling at a constant speed of 46 miles per hour. the formula for the distance traveled at the end of t hours is d=46
jonny [76]

d = 46t

  • First, let's find "d" for 7 hours.

           d = 46(7)

           d = 322 miles                          (7, 322)

  • Next, let's find "d" for 12 hours.

            d = 46(12)

            d =   552 miles                      (12, 552)

  • Finally, let's find "d" for 18 hours.

            d = 46(18)

           d = 828 miles                          (18, 828)
