Answer:
2x^2 + 6.
Step-by-step explanation:
Replace the x in f(x) by g(x):
f(g(x)) = 2(x^2 + 3)
= 2x^2 + 6.
Your simplified answer is 10 (ten)
Sin 2 x + 2 sin x = 0
2 sin x cos x + 2 sin x = 0 / : 2
sin x cos x + sin x = 0
sin x ( cos x + 1 ) = 0
sin x = 0, cos x + 1 = 0, cos x = - 1;
Answer:
x = 0, or x = π
Answer:
15 miles
Step-by-step explanation:
To find the actual distance in miles between Lynwood and Forest Hill, we can use a rule of three:
If 0.25 inch on the map is equivalent to 1 mile, then 3.75 inch on the map is equivalent to what distance:
0.25 inch -> 1 mile
3.75 inch -> X miles
0.25/3.75 = 1/X
X = 3.75/0.25 = 15 miles
The actual distance between Lynwood and Forest Hill is 15 miles.
