Answer:

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

Step-by-step explanation:

Given

$A = 3$ --- Amplitude

$C = \frac{\pi}{4}$ --- Right phase shift

Required

Identify the function

A sinusoidal function is defined as:

$y = A\sin(B(x + C)) + D$

Substitute values for A and C

$y = 3\sin(B(x + \frac{\pi}{4})) + D$

By comparison, only option (D) has the above format where

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

Hence (D) is correct

Use a calculator to solve this problem:<br><br> 28 + 27 × 36

Annette [7]

For this case we have that according to the order of algebraic operations PEMDAS, the multiplications have priority over the addition and subtraction, then, we have the following expression:

$28 + 27 * 36 =\\28 + 972 =\\1000$

Thus, the value of the expression is 1000.

Answer:

$28 + 27 * 36 = 1000$

Answer:

Maggie is 5 years old

Step-by-step explanation:

3M-4+M=16

add 4 to both sides

4M=20

Divide both sides by 4

20/4 = 5

M/Maggie is 5
