Your answer is 6,900 because 904 is close to 900 and then after you just add the 6 so then if you put it together you will get 6,900

Answer questions 13. And 14. Please! Show minimal work...

ale4655 [162]

13. The equation of the given function is $y=4sin[\frac{(t-\frac{4}{3})}{2}]-2$

14. The equation of the cotangent function is $y=cot[2(t-\frac{1}{3})]+2$

Step-by-step explanation:

Let us revise the transformation of the trigonometric function:

y = a f[b(x + c)] + d, where

Amplitude is a
f represents the trigonometry function
Period is 2π/b
Phase shift is c (positive is to the left)
Vertical shift is d

13.

∵ y = a sin( $\frac{2\pi t}{T}$ ), where a is the amplitude

and T is the wave in seconds

∵ The amplitude is 4

∴ a = 4

∵ The period is 4π

∴ T = 4π

From the rules above

∵ The period is 2π/b

∴ T = $\frac{2\pi }{B}$

∴ 4π = $\frac{2\pi }{b}$

- By using cross multiplication

∴ 4π(b) = 2π

- Divide both sides by 4π

∴ b = $\frac{1}{2}$

∵ The phase shift is $-\frac{4}{3}\pi$

∵ c is the phase shift

∴ c = $-\frac{4}{3}\pi$

∵ The vertical shift is -2

∵ d is the vertical shift

∴ d = -2

Now substitutes the values of a, b, c and d in the form of the equation below

∵ y = a sin[b(t + c)] + d

∴ $y=4sin[\frac{1}{2}(t-\frac{4}{3})]-2$

You can write it as $y=4sin[\frac{(t-\frac{4}{3})}{2}]-2$

The equation of the given function is $y=4sin[\frac{(t-\frac{4}{3})}{2}]-2$

14.

y = cot[b(t + c)] + d

∵ The period = π

∵ The period is 2π/b

- Equate π by 2π/b to find b

∴ π = $\frac{2\pi }{b}$

- By using cross multiplication

∴ π(b) = 2π

- Divide both sides by π

∴ b = 2

∵ The phase shift is $-\frac{1}{3}\pi$

∵ c is the phase shift

∴ c = $-\frac{1}{3}\pi$

∵ The vertical shift is 2

∵ d is the vertical shift

∴ d = 2

Now substitutes the values of b, c and d in the form of the equation below

∵ y = cot[b(t + c)] + d

∴ $y=cot[2(t-\frac{1}{3})]+2$

The equation of the cotangent function is $y=cot[2(t-\frac{1}{3})]+2$

HELP ME Solve. h ÷ 4 = 9

Umnica [9.8K]

Isolate the h. Do the opposite of the sign given - Because of equal sign, what you do to one side you do to the other

h/4 = 9
h/4(4) = 9(4)
h = 9(4)
h = 36

36 is your answer for "h"

hope this helps

6 The radius of the base of a cylinder is 39 in. and its height is 33 in.. Find the surface area of the cylinder in terms of s.

Delvig [45]

<u>Answer:</u>

17650 in².

<u>Step-by-step explanation:</u>

Given that the base of cylinder is 39 inch and it's height is 33inches . We need to find the surface area of the cylinder . So we know the TSA of cylinder as ,

$\bf\implies TSA_{(cylinder)}= 2\pi r ( r + h ) \\\\\bf\implies TSA_{(cylinder)}= 2\pi 39 ( 39 + 33) in.^2\\\\\bf\implies TSA_{(cylinder)}= 2\times \dfrac{22}{7}\times 39 \times 72 \\\\\sf:\implies \boxed{\red{\bf TSA_{(cylinder)}= 17650 in^2}}$
