The <em>sinusoidal</em> function that represents the graph is equal to y = 1.5 · cos (2π · t/8) - 3.

<h3>How to derive a sinusoidal function </h3>

In this question we must derive a <em>sinusoidal</em> function based on two given points. <em>Sinusoidal</em> functions are <em>periodic</em> functions that uses <em>trigonometric</em> functions and have the following form:

y = A · cos (2π · x/T) + B      (1)

Where:

  • A - Amplitude
  • T - Period
  • B - Vertical midpoint

The <em>horizontal</em> distance between the midline and the <em>maximum</em> point is equal to a quarter of the period. Hence,

T = 4 · (2 - 0)

T = 8

The <em>vertical</em> midpoint and amplitude of the <em>sinusoidal</em> function are now calculated:

Vertical midpoint

B = - 3

Amplitude

A = - 1.5 - (- 3)

A = 1.5

Then, the <em>sinusoidal</em> function that represents the graph is equal to y = 1.5 · cos (2π · t/8) - 3.

The numerator of a rational number 8 ​
exis [7]

Answer:

We conclude that the numerator of a rational number 8 will be 8.

Step-by-step explanation:

We know that any number which can be written in the form p/q is called a rational number.

i.e. p/q

Where p and q are integers and q≠0.

Here:

  • The numerator is p
  • The denominator is q

Given the number

8

As number '8' can be written in the form p/q, so it is a rational number.

i.e. 8/1

Thus,

  • The numerator = 8
  • The denominator = 1

Therefore, we conclude that the numerator of a rational number 8 will be 8.

A batch of 24 cupcakes requires 9 ounces of flower. Julio made 132 cupcakes for the bake sale. How many pounds and ounces of flo
yuradex [85]

Answer:

49.5 ounces the flower

3 pounds, 1.5 ounces

Step-by-step explanation:

Given that :

24 cupcakes 9 ounces of flower

Number of ounces of flower required for 132 cupcakes will be x

Using cross multiplication method :

24 cupcakes = 9 ounces

132 cupcakes = x ounces

Cross multiply :

24 * x = 132 * 9

24x = 1188

divide both sides by 24 to isolate x

x = 49.5

Hence, 49.5 ounces the flower is required for 132 cupcakes

To express in pounds :

1 pound = 16 ounces

49.5 ounces = 3 pounds 1.5 ounces

Please solve all with explanation
spayn [35]

Answer:

Step-by-step explanation:

4.coordinate points are:

(-2,3)=(x1 , y1)

(1,y)=(x2 , y2)

slope =y2-y1/x2-x1

2=y-3/1-(-2)

2=y-3/1+2

2=y-3/3

do cross multiplication

2*3=y-3

6+3=y

9=y

3 no.

3(1-x)=-2(x-1)

3-3x=-2x+2

3-2=-2x+3x

1=x

4+y/3=2

4+y=3*2

4+y=6

y=6-4

y=2
