Answer: AC = 7√3
tan 30° = 
=> 
Step-by-step explanation:
Step-by-step explanation:
2x + 2y = 184 ---- eqn 1
y = 184 - 2x / 2
y = 92 - x ---- eqn 2
Answer:
18.5÷11.99 is correct the answer is most likly option B
Answer:
a = 8, b = 
Step-by-step explanation:
Given the exponential function
f(x) = a
To find a and b use the given coordinate points on the graph
Using (0, 8 ), then
8 = a
[
= 1 ] , then
a = 8
f(x) = 8
Using (2, 18 ) , then
18 = 8b² ( divide both sides by 8 )
= b² , that is
b² =
( take the square root of both sides )
b =
= 
Thus
f(x) = 8
When you collect terms, for
the first one you get
-x² -3xy +4 = -x² -3xy +4 . . . . . . equivalent equations.
