Answer:
g-1(x)=SQRT{(x-4)/2} + 4
Step-by-step explanation:
I assume that the 2 is the exponent so ^ represents exponent
We know your function is g(x)=2(x-3)^2+4
For inverse functions we swap x and y values, note g(x) is like the y value
Isolate for y
y=2(x-3)^2+4
x=2(y-3)^2+4
(x-4)/2 = (y-3)^2
SQRT{(x-4)/2} + 4 = y
Therefore g-1(x)=SQRT{(x-4)/2} + 4
Step-by-step explanation:
48/4+[6+{12/2 of 3}-4]+20
48/4+[6+18-4]+20
12+20+20
52
Step-by-step answer:
Answer to problems of this kind is the reciprocal of the harmonic mean of the time required.
We need to find the average of the speeds, not the average of the time.
The respective speeds are 1/3 and 1/4.
The average of the speeds is therefore (1/3+1/4)/2 = 7/24 (harmonic mean of the time taken).
The time required is therefore the reciprocal of the unit speed,
T = 1/(7/24) = 24/7 = 3 3/7 minutes, or approximately 3.43 minutes.
1 gallon is equal to 8 pints
3/8 is 3 pints out of a gallon
Answer:
A and B are both 3.
Step-by-step explanation:
The given polynomial is 
.
We factor the GCF to obtain:
We factor further by grouping to get:
![3x[x^2(x-6)+3(x-6)]](https://tex.z-dn.net/?f=3x%5Bx%5E2%28x-6%29%2B3%28x-6%29%5D)
We compare this to the given factored expression:
We must have A=3,B=3, C=-6
