Step-by-step explanation:
a x^2/4
b -x^2/4+3
c 4x^2
d -x^2
Answer:
f^-1 (x)=(x/2)^(1/3)
Step-by-step explanation:
y=2x^3
x=2y^3
2y^3=x
y^3=x/2
y=(x/2)^(1/3)
Answer:
Yes
Step-by-step explanation:
If they're perpendicular, that means that angle ECM = 90 degrees and angle ACE = 90 degrees. To figure out if this works, plug that into the two equations they give:
ECM = 3x + 15
becomes
90 = 3x + 15
75 = 3x
25 = x
ACE = 4x - 10
becomes
90 = 4x - 10
100 = 4x
25 = x
Since you get x = 25 for both, you know that they are perpendicular because they both measure 90 degrees
Ok, this is what you do,
7(^^^^^
84
7 goes into 8 1 time so it would be this
1
7(^^^^
84
- 7
and it leaves you with 14
1
7(^^^^
14
then how many time does 7 go into 14? 2 times
so it would be
12
7(^^^^
14
-14
AND YOUR ANSWER IS 12.
