Plug in the known variables.
5n + 2 n = number of games bowled
5(3) + 2 = 15 + 2 = 17
To answer this, you need to get "d" on one side by itself. To do this, add 8 to both sides of the equation.
d- 8 + 8 = 5 + 8
-8 and +8 cancel out leaving:
d = 13
Your answer is d = 13
The answer is C. It has the wrong graph labels.
From the identity,
sin^2(x)+cos^2(x)=1
then
cos(x)=sqrt(1-sin^2(x))
where sin(x) is given as 0.42.
Note that the above answer applies to 0<x<90 degrees
250 divided by 10 squared is 2.5
