Question

HELPPPPPPPPP! fast please will mark first as brainliest!

Answer 1

Answer:

B

Step-by-step explanation:

We have

$- 4 \sin(7t + 3)$

Here the value of a is always positive because distance is positive

$| - 4| = 4$

Next, we factor out 7 to get our period

$- 4 \sin(7(t + \frac{3}{7} ) )$

So our period is

$\frac{2\pi}{7}$

Next, our phase shift we set the inner parenthesis equal to 0.

$t + \frac{3}{7} = 0$

$t = - \frac{3}{7}$

So our phase shift is -3/7

Answer 2

Answer:

The answer is B

Step-by-step explanation:

B is correct

amplitude:4

Period 2pi/7

phase shift: -3/7
