Answer:

y=4\sin(\frac{3}{2}x+\frac{2\pi}{3})

Step-by-step explanation:

The graph of the cosine function can be obtained by shifting the sine function to the left by \frac{\pi}{2} units.

The given cosine function is:

y=4\cos(\frac{3}{2}x+\frac{\pi}{6})

When we shift this function to the left by \frac{\pi}{2} units, we obtain a sine function

y=4\sin(\frac{3}{2}x+\frac{\pi}{6}+\frac{\pi}{2})

y=4\sin(\frac{3}{2}x+\frac{2\pi}{3})

These two functions have the same graph

The second option is correct.

Answer:

y = (x - 3)² - 4      Vertex form

(3, -4)    Vertex

Step-by-step explanation:

f(x) = x² - 6x + 5

Complete the square

y = (x - 3)² + 5 - (-3)²

y = (x - 3)² + 5 - 9

y = (x - 3)² - 4      Vertex form

(3, -4)    Vertex

Select the correct answer. For what value of x is sin x = cos 19º, where 0°< x < 90°? OA. 38° ° O B. 71° OC. 26° O D. 19°​
Lerok [7]

Answer:

x = 71°

Option B is correct answer.

Step-by-step explanation:

We need to find for what value of x is sin\: x = cos 19^{\circ}, where 0°< x < 90°?

Solving:

sin\: x = cos\: 19^{\circ}\\Finding \:cos\: 19^{\circ}=0.94551\\Putting\:value:\\sin\:x=0.94551\\Now\:taking\:sin\:inverse\\x=sin^{-1}(0.94551)\\x=71^{\circ}

So, we get x = 71°

Option B is correct answer.

What is the answer to 6x = 54
Morgarella [4.7K]

Answer:

It's division because to get x by itself, you need to divide both sides. X = 9

Step-by-step explanation:

6x = 54

Divide both sides by 6

54/6 = 9
