Answer:
0.6
Step-by-step explanation:
cos H = GH/FH
FH^2=20^2+15^2
FH^2=400+225=625
FH=25
cos H= 15/25=3/5=0.6
Answer:

Step-by-step explanation:
Given the function

We can rewrite it as

Now we can apply the power rule

Now we can rewrite it

Now we can plug in x=-8

Answer:
X+4
Step-by-step explanation:
Nth term = a1r^(n-1)
4th term = 15* (1/3)^3 = 15/27 = 5/9
X is -1 . if you put the equation into form and do a two step equation you should end with -1
