90 = 2 · 3 · 3 · 5 = 2 · 3² · 5¹
If n has the form

and

is an integer, then greatest possible value of n = 3² · 5¹ =
45
(2, 4) is an ordered pair that solves truly into that equation.
<u>Short answer</u> = C) 8/10
<u>Working :</u>
Tan A = 8/6 = Opposite / AdjacentOpposite = 8 units
Adjacent = 6 units
Hypotenuse = 
= 
= 
= 10 units
Cos B = Adjacent/ Hypotenuse
∴ cos B= 8/10
Answer: g(f(4))=9
Step-by-step explanation:
To find g(f(4)), you first find f(4). Then, you plug it into g(x).
f(4)=4-7 [subtract]
f(4)=-3
Now, we know f(4) into g(x).
g(f(4))=(-3)² [exponent]
g(f(4))=9
Now, we know that g(f(4))=9.
