f(x) = V22
g(x) = V322
Find (f .g)(x). Assume x2 0.
O A. (f.g)(x) = 8x
B. (f.g)(x) = 8VC
O c. (f.g)(x) = 32x
D. (f.g)(x) = V34x
Answer:
Step-by-step explanation:
g(x) = √(32x) = √(2⁵x) = 4√(2x)
(f∘g)(x) = f(g(x))
= f(4√(2x))
= √(2 ⋅ 4√(2x))
= √(8√(2x))
= √8∜2∜x
= ∜(2⁷x)
= ∜(128x)
which doesn’t match any of the choices. There’s an error in the question.
I believe that the functions were written incorrectly and the x should not be part of the radicands (see attachment). That makes the answer A.
Lucas is having the Sunday blues and hoping for a snow day this week. He measures that there are currently 10
inches of snow on the ground.
The forecast for Monday is a 50% chance of 2.5 inches of snow. If it doesn't snow, 1.5 inches of snow will melt.
The forecast for Tueſday is a 50% chance of 1.5 inches of snow. If it doesn't snow, 0.5 inches of snow will melt.
The weather on Monday and Tuesday are independent events.
If X is a random variable that represents the amount of snow on the ground after Tuesday, drag the bars to
graph the probability distribution for all possible values of X.
Answer:
All probablities are 0.25
Step-by-step explanation:
Got it right on Khan
From the given question, we can see that there is currently ten inches of snow.
With this in mind, we can see that the weather forecast for Monday is 50% probability for 2.5 inches of snow which is 1/2 for 2.5 inches of snow.
Furthermore, if it does not snow, then there would be 2.5-1.5= 1.0 inches of snow
Additionally, the weather forecast for Tuesday is 50% probability for 1.5 inches of snow which is 1/2 for 2.5 inches of snow.
Furthermore, if it does not snow, then there would be 1.5-0.5= 1.0 inches of snow
Given that the weather on Monday and Tuesday are independent events, then all the probabilities would be 1/2:1 which would be 0.5 inches of snow.
With this in mind, all the probabilities for chances of snow is 0.25
Therefore, we can see that all the possible values of x would be 0.25

three times the quotient of 3 and 5
Three times the quotient of 3 and 5 is equivalent to 1.8
The question asked us to convert the word problem to equation and solve.
The quotient of 3 and 5 is expressed as 3/5
Taking the product of the result and 3 will give;
Three times the quotient of 3 and 5 = 3 * 3/5
Three times the quotient of 3 and 5 = 9/5 = 1.8

write the first four terms of the sequence
the rule is: start at 3 1/8, subtract 3/4
Answer:
start at 3 1/8
1st teem = 3 1/8
2nd term = 3 1/8 - 3/4
= 25/8 - 3/4
= 25/8 - 6/8
=19/8

3rd term = 2 3/8 - 3/4
= 19/8 - 3/4
= 19/8 - 6/8
=13/8
= 1 5/8
4th term = 1 5/8 - 3/4

Step-by-step explanation:
The demand d for a company’s product at cost x is predicted by the function d(x) = 500 – 2x. The price p in dollars that the company can charge for the product is given by p(x) = x + 5. Use the formula Revenue = price × demand to find the revenue function for the product.
R(x) = ________ + ________ x – _______ x^2
Answer:
-2x²+490x+2500
Step-by-step explanation:
Given that,
Demand, D(x) = 500-2x
The price for the product, P(x) = x+5
We need to find the revenue for the product. The formula for the revenue is given by :
Revenue = price × demand
Substitute all the values,
R = (x+5)(500-2x)
= 500x -2x² + 2500 -10x
= -2x²+490x+2500
So, the expression for the revenue function is "-2x²+490x+2500".

Step-by-step explanation:
Answer is in the photo
Hope it helllps
Good luck
The division of the number 405 in the ratio 4:11 is 297 and 108 respectively.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the ratio is 4:11. the number is 405 which has to be divided by the ratio.
Let the common ratio between the numbers is x. Form an equation and solve for x.
4x + 11x = 405
15x = 405
x = 405 / 15
x = 27
The numbers are,
4x = ( 4 x 27 ) = 108
11x = ( 11 x 27 ) = 297
Therefore, the division of the number 405 in the ratio 4:11 is 297 and 108 respectively.

What is measurement angle B?
Answer: 80 degrees
Step-by-step explanation:
Answer:
B = 54 to the nearest degree.
Step-by-step explanation:
Remark
This is a sine law question. They can be rather nasty because no answer or 2 answers are possible. This one is well behaved because B, you are told, is acute. The two answer kind needs the supplement of an acute angle.
Sorry this blabs on and shouldn't. You are looking for <B
Formula
Sin(<B)/the side opposite = Sin(<A) / side opposite it
Simplified
Sin(<B) / 9 = Sin(A)/11
Sin(<B) / 9 = Sin(80) / 11 Multiply both sides by 9
9*Sin(B) / 9 = 9 * Sin(80) /11 The 9s Cancel
Now all you need to do is put it in your calculator. Do you need the steps?
Sin(B) = 9*sin(80) / 11
Sin(B) = 9 * 0.9848 /11
Sin(B)= 0.8058
B = Sin-1(0.8058)
B = 53.68
B = 54

Which function is equivalent to g(x) = x2 + 15x – 54?
g(x) = (x + 9)(x – 6)
g(x) = (x – 9)(x + 6)
g(x) = (x – 18)(x + 3)
g(x) = (x + 18)(x – 3)
Answer:
g(x)=(x+18)+(x-3)

The function i.e. g(x)=(x+18)(x-3) equivalent to the given equation.
Given that,
The equation is [tex]g(x) = x^2 + 15x - 54[/tex].We need to solve it.

Rotate one of them so the right angle is in the same orientation as the other one.
1. AB = DE
2. CB = FE
3. AC = DF
4. Compare the length of two known sides: cb and EF
CB = 3 and EF = 8
8/3 = 2 2/3 scale factor
5. Ab is side de. Multiply the length of ab by the scale factor:
4 x 2 2/3 = 10 2/3
6. FD = sqrt ( 10 2/3^2 + 8^2)
FD = 13 1/3

A furniture rental store charges a down-payment of $100 and $72.50 per month for a table. Hilde paid $535 to rent the table. Solve 72.50n + 100 = 535 to find the number of months Hilde rented the table.
Answer:
6 months
Step-by-step explanation:
First, subtract 100 from both sides
72.50n + 100 = 535
72.50n = 435
Divide each side by 72.50
n = 6
So, Hilde rented the table for 6 months
