Please help!

Aloiza [94]

Answer:

$4 \sin( \frac{2}{7}x ) + 1$

Step-by-step explanation:

Let use the basic function of sin first.

Since the midline is 1 and the max point is 5, the amplitude is 4.

The midline is 1 since the midline is at 0,1.

Since we know the distance of the max and midline x values

We can multiply that by 4 to find our period.

$\frac{7\pi}{4} \times 4 = 7\pi$

Use the equation 2pi/b to find the b we would use in our equation.

$\frac{2\pi}{b} = 7\pi$

The answer is

$\frac{2}{7}$

so our equation is

$4 \sin( \frac{2}{7}x ) + 1$

In 10 seconds Lauren counts 5 vehicles passing by her house at that rate how many vehicles would passing by in one hour

Dafna11 [192]

Answer:

1,800 vehicles

Step-by-step explanation:

We need to find what fraction of an hour 10 seconds is, so we will divide 60 (minutes) by 1/6 (minutes). From solving this, we will get 360. That is how many 10 second chunks pass in an hour. We will multiply 360 by 5, and we get 1,800 vehicles!
