Answer:

The unit rate is 1.5

Step-by-step explanation:

Given

Ratio = 4/7 : 8/21

Required

Determine the unit rate

To do this, we need to express the ratio as:

Ratio = m : 1

<em>Where m is the unit rate</em>

Ratio = 4/7 : 8/21

Express as fraction

Ratio = \frac{4/7 }{ 8/21}

Solve

Ratio = \frac{4}{7} * \frac{21}{8}

Ratio = 1.5

Express as ratio

Ratio = 1.5 : 1

<em>Hence, the unit rate is 1.5</em>

Write a sine function that has a midline of 2, an amplitude of 4 and a period of 11.
svetoff [14.1K]

Answer:

y = 4 sin(2π/11 x) + 2

Step-by-step explanation:

y = A sin(2π/T x + B) + C

where A is the amplitude,

T is the period,

B is the phase shift,

and C is the midline.

A = 4, T = 11, and C = 2.  We'll assume B = 0.

y = 4 sin(2π/11 x) + 2
