tatyana61 [14]

Answer:

y=2 cos (π/4x-π/4)

Step-by-step explanation:

Given

A cosine function has an amplitude of 2, a midline of 5 and a period of 8.

To find:

A cosine function.

Explanation:

Let the function be,

$y=Acos(ws+p)$

Since amplitude is 2.

Then,

$A=2$

Also, since the period is 8.

Then,

$w=\frac{2\pi }{8}$

$w=\frac{\pi }{4}$

And, since midline is 5.

Hence, the cosine function is,

y=2 cos ( $\frac{\pi }{4}$ x- $\frac{\pi }{4}$

Answer:

the option are A.

92.4%

7.6%

91.8%

8.2%

Step-by-step explanation:

Think of it what times 61 will equal 66....

61 () = 66

(?%) = 66 /61

(?) = 1.08196

so now it gets tricky get the percentage increase correct

based on the given answer choices I'ld say it is D

% increase = (1.08196 - 1) (100) Why the subtraction of one? ?

= 8.196%

= 8.2 %
