Answer/Step-by-step explanation:

Total Distance = 3Ft

a) Determine the amplitude and period of a sinusoidal function that models the bobbing buoy.

Amplitude = 3/2 = 1.5         period = 10 second

\frac{0}{1} =\frac{2\pi }{b}      b=\frac{\pi }{5}         No ph. Shift

b) Write an equation of a function that models the buoy with x=0 at its highest point.​

y= 1.5 cos ( \frac{\pi }{5} x)

Simplify the following expression. 1/4 (24-16x)<br> a. 6+4x<br> b. 6+4<br> c. 6-4x<br> d. 6-4
adoni [48]
Answer is 6-4x

 <span>1/4 evaluates to 1/4
</span>
<span>Multiply x and 16
</span>
<span>Multiply x and 1

after you have the answer it should come out to  </span>24-16x then multiply 1/4 * 24-16x

1/4 *24=6


<span>1/4*(24-16*x) evaluates to 6-4x</span>

14 times a number decreased By eight is 22 Increase by 20 times The same number
kotegsom [21]

Answer:

14x - 8 = 22 + 20x

x = -5

Step-by-step explanation:

Let "the number" be represented by x

Take each part of the statement and translate into algebraic form

"14 times a number" 14x

"decreased By eight" -8

"is" =

"22 Increased by" 22 +

"20 times The same number" 20x

Put the equation together. Solve for x by isolating.

(

14x - 8 = 22 + 20x

14x - 8 - 20x = 22 + 20x - 20x Subtract 20x from both sides

-6x - 8 = 22

-6x - 8 + 8 = 22 + 8  Add 8 to both sides

-6x = 30

-6x ÷ -6 = 30 ÷ -6  Divide both sides by -6

x = -5

Find cos B, sinB,tanb
emmasim [6.3K]

Using right triangle relations, we will get:

  • tan(B) = 1.05
  • sin(B) = 0.735
  • cos(B) =  0.7

<h3>How to find the value of the trigonometric equations?</h3>

We assume that bot triangles are equivalent, then the angle B will be the same as the angle Z.

Now remember the relations:

  • tan(θ) = (opposite cathetus)/(adjacent cathetus).
  • sin(θ) = (opposite cathetus)/(hypotenuse)
  • cos(θ) = (adjacent cathetus)/(hypotenuse).

If we step on angle B, we have:

  • opposite cathetus = 29.4
  • adjacent cathetus = 28
  • hypotenuse = 40.6

Replacing that, we get:

  • tan(B) = 29.4/28 = 1.05
  • sin(B) = 29.4/40.6 = 0.735
  • cos(B) = 28/40.6 = 0.7
