Mekhanik [1.2K]

Answer:

5 1/3

Step-by-step explanation:

16 - (2z-4)/3

Let z = 18

16 - (2*18-4)/3

Multiply inside the parentheses first

16 - (36-4)/3

Subtract inside the parentheses

16 - (32/3)

Divide inside the parentheses and change to a mixed number

16 - 10 2/3

Borrow 1 from 16 in the form of 3/3

15 3/3 - 10 2/3

5 1/3

What is the period for the function y = -4 cos (5x +3)? (4.3)

BlackZzzverrR [31]

The periodicity of function is $\frac{2 \pi}{5}$

Solution:

Given that we have to find the period of function

Given function is:

$y = -4 + cos(5x+3)$

Use the below formula:

$\mathrm{Periodicity\:of\:}a\cdot \cos \left(bx\:+\:c\right)\:+\:d=\frac{\mathrm{periodicity\:of}\:\cos \left(x\right)}{|b|}$

Thus,

$Peridocity\ of\ cos(5x + 3) - 4 = \frac{\text{periodicity of cos(x)}}{5}$

Now find the periodicity of cos(x)

We know that,

periodicity of cos(x) = $2 \pi$

Therefore,

$Peridocity\ of\ cos(5x + 3) - 4 = \frac{2 \pi}{5}$

Thus the periodicity of function is $\frac{2 \pi}{5}$
