(y¹-y¹/x¹-x¹)
8-11/10-19
-3/-9
1/3
Step-by-step explanation:
1/3 or one-third is your answer!
Let be Z the money ;
We have ( 40 / 100 ) x Z = $85 ;
( 4 / 10 ) x Z = $85 ;
( 2 / 5 ) x Z = $85 ;
Z = $( 85 x 5 ) ÷ 3 ;
Z = $425 ÷ 3 ;
Z = $141,66 ≈ $142 ;

Answer:

Step-by-step explanation:
we want to solve the following trigonometric equation:

The first step of solving trigonometric equation is to rewrite the equation in terms of one trigonometric function . With Pythagorean theorem, we know that sin²x=1-cos²x . It will be helpful to rewrite the equation in terms of one trig functions. Therefore, substitute 1-cos²
in the place of sin²
:

simplify:

Consider cos²
x. Thus,

solving the quadratic equation yields:

back-substitute:

take inverse trig in both sides

In conclusion,

Answer:
answer is b
