Sorry this took awhile.
So for Friday, it would be $550
Saturday, $895
Sunday, 1,095
So the total is $2540 if you add the numbers up. Hope this helps!
The correct order to express cos3x in terms of cosx is; As shown in steps 1 to 9 below.
<h3>How to simplify Trigonometric Identities?</h3>
The steps to simplify the trigonometric identities cos 3x in terms of cos x are as follows;
Step 1; cos x = cos(2x + x)
Step 2; cos(2x) cosx - sin(2x) sinx
Step 3; 1 - 2sin^2x(cosx) -(2sinxcosx)sinx
Step 4; cosx - 2sin²x cosx - 2sin²x cosx
Step 5; cosx - 4sin²x cosx
Step 6; cosx( 1 - 4sin²x)
Step 7; cosx{1 - 4(1 - cos²x)}
Step 8; cosx{-3 + 4cos²x}
Step 9; 4cos³x - 3cosx

Answer:
the ratio of perimeters is 3/5
the ratio of areas is 9/25
Step-by-step explanation:
first we divide the given sides of both figures
perimeter=side 1/side 2
=15/25
p=<u>3</u><u>/</u><u>5</u>
to find the ratios of the area
=(side 1/side 2)^2
=(3/5)^2
=<u>9</u><u>/</u><u>2</u><u>5</u>
