Answer:
y=2x
100 miles
Step-by-step explanation:
The slope is determined by change of y/ change of x
when using the points (0,0)-(50,100) is
100-0/50-0= 100/50=2
so the slope is 2.
Also there is no Y intercept on the equation bc it goes through the origin.
100 miles is the y point for 50 miles per hour
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
