<h3>Answer: Choice B</h3>

Explanation:

The general template of a sine function is

y = Asin(B(x-C))+D

The value of B is the only thing that determines the period T. We ignore every other term.

It turns out that T = 2pi/B which can be solved to B = 2pi/T

Plug in the given period of T = 8pi and compute to get

B = 2pi/T

B = (2pi)/(8pi)

B = 2/8

B = 1/4

This means that the term out front of the x is 1/4 and the equation must be y = \sin\left(\frac{1}{4}x\right) which matches with answer choice B.

At a sale, dresses were sold for $90 each. This price was 75% of a
gulaghasi [49]

Answer:

A dress originally costs $120

Step-by-step explanation:

To find the original cost of the dress, we will follow the steps below;

let x represent the original cost of the dress

75% of x  = $90

\frac{75}{100}  ×    x   = $90

\frac{75X}{100}  =   $90

MULTIPLY both-side of the equation by 100

\frac{75X}{100} × 100 =   $90×100

At the right-hand side of the equation, 100 will cancel out 100, leaving us with just 75x

75x = $9000

DIVIDE both-side of the equation by 75

75x/75 = $9000/75

At the left-hand side of the equation 75 will cancel-out 75 leaving us with just x

x=  $9000/75

x = $120

A dress originally costs $120

Amelia is going to buy some cards for her friends.Each card costs $3.She finds a coupon for $2 off the entire purchase.Write an
dalvyx [7]

y = ( 3 * x ) - 2.

This is because the card costs for 3 $ and should be multiplied by the number of total cards she buys in that particular day. So 3 * x.

Now as she has got a 2$ off coupon, whatever the total is she gets 2 dollars off on that price. So we will subtract 2 at that time. FInally all this summed up would be equal to y.

Two rectangles are similar. The ratio of their corresponding sides is 1:4.
larisa [96]

ratio of perimeter is the same as ratio of sides so perimeter would be 1:4

since area is in square units you need to square the ratio (1:4)^2 which is 1:16
