Step-by-step explanation:
For each pair of functions f and g below, find f(g(x)) and g(f(x)).
Then, determine whether f and g are inverses of each other.
Simplify your answers as much as possible.
(Assume that your expressions are defined for all x in the domain ofthe composition.
You do not have to indicate the domain.)
Answer:
a) f(g(x)) = [tex]\frac{1}{2(\frac{1}{2x} )}[/tex] = [tex]\frac{1}{\frac{1}{x} } }[/tex] = x
g(f(x)) = [tex]\frac{1}{2(\frac{1}{2x} )}[/tex] = [tex]\frac{1}{\frac{1}{x} } }[/tex] = x
f and g are inverses
b) f(g(x)) = x + 3 + 3 = x + 6
g(f(x)) = x + 3 + 3 = x + 6
f and g are not inverses
Step-by-step explanation:
a)
f(g(x)) = [tex]\frac{1}{2(\frac{1}{2x} )}[/tex] = [tex]\frac{1}{\frac{1}{x} } }[/tex] = x
g(f(x)) = [tex]\frac{1}{2(\frac{1}{2x} )}[/tex] = [tex]\frac{1}{\frac{1}{x} } }[/tex] = x
Since f(g(x)) = g(f(x)) = x, then f and g are inverses
b)
f(g(x)) = x + 3 + 3 = x + 6
g(f(x)) = x + 3 + 3 = x + 6
Since f(g(x)) = g(f(x)) ≠ x, then f and g are not inverses

in an arithmetic sequence, the sum of the first n terms is s_n=n^2. find a_8
i'm not sure how to do this, so yeah
Answer:
[tex]a_{8} = 15[/tex]
Step-by-step explanation:
[tex]a_{1} + a_{2} + ..... + a_{7} + a_{8} = 8^{2} = 64[/tex]
[tex]-a_{1} - a_{2} ..... - a_{7} = - 7^{2} = -49[/tex] Now add the two equations
[tex]a_{8} = 64 - 49 = 15[/tex]
[tex]a_{8} = 15[/tex]

Step-by-step explanation:
Carla and Andrew have 29 puppies. Andrew has 8 more than twice Carla How many puppies does person have?
Answer:
Andrew has 22 puppies, Carla has 7 puppies.
Step-by-step explanation:
Let's set up an equation.
Carla and Andrew have 29 puppies.
C + A = 29
Andrew has 8 more than twice Carla.
A = 2C + 8
Let's use substitution by plugging A into C + A = 29.
A = 2C + 8 & C + A = 29
C + (2C + 8) = 29
Now, let's combine like terms.
3C + 8 = 29
Subtract 8 from both sides.
3C = 21
Divide both sides by 3.
C = 7
Carla has 7 puppies. Plug in this value back into C + A to find how many puppies Andrew has.
C + A = 29
7 + A = 29
A = 22
Andrew has 22 puppies.
Let's check our work. Plug in Andrew and Carla's number of puppies back into our original equations.
C + A = 29
7 + 22 = 29
29 = 29
Correct!
A = 2C + 8
22 = 2(7) + 8
22 = 14 + 8
22 = 22
Your answer is correct!
Hope this helps!
what is 64x6+27 written as a sum of cubes?
Answer:
To transform the given expression to the sum of cubes, calculate first the cube root of the terms. The cube root of the first term, 64x^6 is 4x^2 and that of the second term, 27 is 3.
Thus, the answer to this is (4x^2)^3 + 3^3

Step-by-step explanation:
Answer:
0.03 or 3%
Step-by-step explanation:

r = 1200/(7000 * 6)
r = 1200/42000
r = 0.03
the height of the rectangular box is 4 times its width, and its length is 2 in more than its width. the volume of the box is 60in^3
Step-by-step explanation:
height= 4b
length = 2 + b
volume = 60in³
or, l ×b × h = 60in³
or, (2+b) × b × 4b = 60in³
or, 4b²(2+b) = 60in³
or, 8b² + 4b³ = 60
or, 2b² + b³ = 15
or, b³ + 2b² -15= 0
b= 1.95
l= 2+1.95=3.95
h= 4×1.95 = 7.8

Carrie is planning her birthday party at a restaurant. She cannot spend more than $75 on the party. The cost per person for the meal is $12. There is also a $10 charge for the room. The number of friends, f, that Carrie can invite is represented by the inequality 12f + 10 < 75. How many friends can Carrie invite to the party if her budget is $75 or less?
Answer:
Carrie can only bring 4 people.
Step-by-step explanation:
75-10= 65
65-12= 53
12 * 4 =48
anything above that is more than her budget.

find the measure of the arc or angle indicated. assume that lines which appear tangent are tangent
Answer:
Option (1)
Step-by-step explanation:
By the property of alternate segment theorem,
"Angle formed between the tangent and the chord in a circle measures the half of the measure of the intercepted arc"
m(∠EFG) = [tex]\frac{1}{2}[/tex] × m(minor arc FG)
minor arc FG = 2m(∠EFG)
= 2(76°)
= 152°
Therefore, Option (1) will be the correct option.

PLLSSSSS HELPPPP I DONT GET THIS AT ALL
Answer:
[tex]y\leq 4[/tex]
Step-by-step explanation:
The range is about the y values, and by looking at this parabola we can see that the maximum value is a 4. So the range would be the maximum and below (where the parabola extends to). So the values in the range would be equal to 4 and less than since the parabola is negative.
Hope this helps :)
