Question 5 of 30<br> What is the period of the graph of y<br> 5cos(4x – 1) + 3?

Anastaziya [24]

Answer:

Period is $\frac{\pi}{2}$

Step-by-step explanation:

For the function $y=acos(bx-c)+d$ , the period is $\frac{2\pi}{|b|}$ .

Therefore, the period of the function is $\frac{2\pi}{|b|}=\frac{2\pi}{|4|}=\frac{2\pi}{4}=\frac{\pi}{2}$ .

What this means is that the function's wave cycle will repeat every $\frac{\pi}{2}$ units.

Please help me ... 6a + 2(c - b) when a = 2, b = 1, and c = 9 I know thë answer but I just need an explanation

Angelina_Jolie [31]

Answer:

Step-by-step explanation:

Let the expression representing a situation is,

y = 6a + 2(c - b)

Where, a, b and c are the constants

If a = 2, b = 1 and c = 9

By substituting these values in the expression,

y = 6(2) + 2(9 - 1)

y = 12 + 16

y = 28

Therefore, for all given values of the constants value of y is 28.
