Please, refer to the images below
Step-by-step explanation:
We need to solve for x in the equation
cos (x+ pi) ^2 = sin (x)
cos (x+ pi) = - cos(x)
(-cos (x)) * (-cos (x)) = sin(x)
cos(x) ^2 = sin(x)
We know that
cos(x) ^2 + sin(x) ^2 = 1
cos(x) ^2 = 1 - sin(x) ^2
1 - sin(x) ^2 = sin(x)
sin(x) ^2 + sin (x) -1 = 0
Let A = sin(x)
A^2 + A - 1 = 0
(solutions attached in picture 1)
This means that
x = arcsin(A)
(solutions attached in picture 2)
Answer:
Step-by-step explanation:
so he gets a 12% commission on his sales. He sold a slide that costs 270.
so he would get 12% of 270
turn ur percent to a decimal..." of " means multiply
0.12 * 270 = $ 32.40 <===
The ratio of the park's length and width is 300/240=5/4
if he takes the length as 10in then the width should be 8in,
so it's area should be 80in²
