Let f(x) = 2/x and g(x) = 2/x what is (g o f)(x)?
Answer:
(g o f)(x) = x
Step-by-step explanation:
Given the functions f(x) = 2/x and g(x) = 2/x
(g o f)(x) = g(f(x))
g(f(x)) = g(2/x)
Replace x with 2/x in g(x)
g(f(x)) = 2/(2/x)
g(f(x)) = 2 * x/2
g(f(x)) = 2x/2
g(f(x)) = x
Hence the composite function g o f)(x) is x

Thanh purchased crawfish and shrimp at a local seafood market to use at her restaurant. At the market, crawfish cost $3 per pound and shrimp cost $5 per pound. Thanh spent $200 total on 52 pounds of seafood. The system of linear equations shown can be used to represent this situation. In the system of linear equations, c represents the pounds of crawfish purchased and s represents the pounds of shrimp purchased.
{c+s=523c+5s=200
How many total pounds of shrimp did Thanh purchase?
Enter your answer in the box.
Answer:
22 pounds
Step-by-step explanation:
c+s=52, c = 52-s
3c+5s=200
3(52-s) +5s = 200
156 - 3s +5s = 200
5s-3s = 200-156
2s = 44
Shrimp = 44/2 = 22 pounds
How do I express the letters in bracket as the subject of the formula ?
especially the 1/2 power is new and unfamiliar to me.
Answer:
[tex]n = 144m^2 - 1[/tex]
Step-by-step explanation:
__________________________________________________________
FACTS TO KNOW BEFORE SOLVING :-
Let x be a number. ⇒ [tex]x^{\frac{1}{2}}[/tex] can also be written as [tex]\sqrt{x}[/tex].To make any variable the subject of any formula , we need to isolate it.__________________________________________________________
According to the question ,
[tex]3m = \frac{(n + 1)^{\frac{1}{2} }}{4}[/tex]
Lets multiply both the sides by 4.
[tex]=> \frac{(n + 1)^{\frac{1}{2} }}{4} \times 4 = 3m \times 4[/tex]
[tex]=> (n + 1)^{\frac{1}{2} } = 12m[/tex]
It can be also written as :-
[tex]=> \sqrt{(n + 1)} = 12m[/tex]
Lets square both the sides.
[tex]=> [\sqrt{(n + 1)} ]^{2} = (12m)^{2}[/tex]
[tex]=> n + 1 =144m^2[/tex]
[tex]=> n = 144m^2 - 1[/tex]
if I cupcake have 240 calories for 3 servings how many calories would it have for 5 servings
Answer:
400 calories
Step-by-step explanation:
One cupcake has 80 calories. 80 x 5 = 400
Answer:
400 Calories
Step-by-step explanation:
If there are 240 calories in 3 servings, In one serving there must be 80 because
240/3 = 80
And since there are 80 calories in one serving, in 5 servings there will be 5 times the amount of calories there is in one serving so
5 * 80 = 400

The cost c in dollars of manufacturing x bicycles at a production plant is given by th function shown below C(x)=5x^2-1000x+63,500. How many bicycles must be manufactured to minimize the cost
Answer:
100 bicycle
Step-by-step explanation:
Given the cost c in dollars of manufacturing x bicycles at a production plant expressed as C(x)=5x^2-1000x+63,500.
x is the number of bikes
To minimize the cost, dC/dx = 0
dC/dx = 10x - 1000
Since dC/dx = 0
0 = 10x - 1000
-10x = -1000
x = 1000/10
x = 100
Hence the number of bicycles that must be manufactured to minimize the cost is 100 bicycle

Find length of BA don’t answer if you’re a fake bot
Answer:
BA = 22.57
Step-by-step explanation:
perimeter = 60
2BZ + 2ZA = 60
BZ + ZA = 30, BZ = 30 - ZA
tan 25° = 0.4663
0.4663 = ZA/BZ = ZA/(30 - ZA)
multiply both sides by (30 - ZA):
0.4663(30 - ZA) = ZA
simplify:
13.99 -0.4663ZA = ZA
add 0.4663ZA to each side:
13.99 = 1.4663ZA
divide both sides by 1.4663:
ZA = 9.54
BZ = 30 - 9.54 = 20.46
BA² = 9.54² + 20.46²
BA² = 509.62
BA = 22.57

hello gimme-Dem points.
Step-by-step explanation:
ASAP!!!!!!!!! HELP ME WITH THIS QUESTION PLEASE!!!!!! IT IS TRICKY SO LOOK CAREFULLY AND HELP ME GET THE CORRECT ANSWER!!!!
May someone help me out with these problems? Please explain
Answer:
Well you have to solve each problem first to make them the same. Let's do decimals.
a) The square root of 58 is 7.61577310586. Let's round that to 7.62. You can solve this with a calculator.
b) Simply -32.0, since it is a whole negative number.
c) I think there's a typo, 'C' is the second 'b)', which is 49/7. 49 divided by 7 is seven, hence the decimal would be 7.0
d) 2.65 repeated, already a decimal, does not need changed.
e) The square root of 6 is 2.44948974278. Let's round that to 2.45.
f) is just 0. no decimal, just 0.
Now that you have these as the same form of number, you have to put them into one of these categories. The categories can be found below.
Any square root number is irrational. Any never ending number is irrational, like pi, but there are none of those in this situation. So a, and e are all irrational.
Any repeated number, in this case, 2.65 repeated, is a rational number, as is any decimal or fraction, but there are none of these, so d is rational.
-32 is and integer, because it is a negative whole number, so b is an integer.
Whole numbers are any numbers 0+. So f is the only answer that is a whole number.
Natural numbers are any numbers 1+. So c or the second b is a natural number.
Hope this helps :)

marty has 1 1/3 jugs of apple juice. he uses 3/4 of the juice to make freeze pops. what fraction amount of a jus doe marty have?
Answer:
He has 1/3 of a jug left.
Step-by-step explanation:
He starts with 1 1/3 jugs.
He uses 3/4 of 1 1/3 jugs.
A full amount is 1 or 4/4. If he uses 3/4, he has 1/4 left since
1 - 3/4 = 4/4 - 3/4 = 1/4
That means he has 1/4 of 1 1/3 jugs left.
We need to multiply 1/4 by 1 1/3.
1/4 * 1 1/3 =
= 1/4 * 4/3
= 4/12
= 1/3
Answer: He has 1/3 of a jug left.

10 green marbles
6 blue
Without looking in the hat, Tessa takes out a marble random. She replaces the marble and then takes out another marble from the hat. What is the probability that Tessa takes out a blue marbles in both draws?
The probability that Tessa takes out blue marbles in both draws will be 6.25%.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
The number of marbles of different colors stored in a hat is listed below:
8 red marbles
10 green marbles
6 blue
Without looking in the hat, Tessa takes out the marble randomly.
She replaces the marble and then takes out another marble from the hat.
Then the probability that Tessa takes out blue marbles in both draws will be
Total marbles = 6 + 10 + 8 = 24
Then we have
[tex]\rm P = \dfrac{6}{24} \times \dfrac{6}{24}\\\\P = \dfrac{1}{16}\\\\P = 0.0625\\\\P = 6.25\%[/tex]

You put $200 into an account earning 6% interest compounded yearly.
Write a rule to model the situation. Your answer should not include spaces and be formatted like: y=3(4)^x
Based on your equation, when will the account be worth $2500? Round your answer to the nearest hundredths place and do not include labels. Ex. 3.14
Answer:
43.35 years
Step-by-step explanation:
From the above question, we are to find Time t for compound interest
The formula is given as :
t = ln(A/P) / n[ln(1 + r/n)]
A = $2500
P = Principal = $200
R = 6%
n = Compounding frequency = 1
First, convert R as a percent to r as a decimal
r = R/100
r = 6/100
r = 0.06 per year,
Then, solve the equation for t
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(2,500.00/200.00) / ( 1 × [ln(1 + 0.06/1)] )
t = ln(2,500.00/200.00) / ( 1 × [ln(1 + 0.06)] )
t = 43.346 years
Approximately = 43.35 years

Many large cities use taxes on entertainment tickets to pay for improvements to public facilities, like stadiums, arenas, and concert venues. A city council proposal would increase the current ticket tax in order to raise funds for a new public concert hall. Council representatives plan to conduct a survey outside of a large concert in the summer and ask selected adults if they would support an increase in the ticket tax to pay for the new concert hall. Which type of bias will most likely affect the survey results? This is response bias because it is likely that many who respond will not provide a truthful opinion of the ticket tax. This is undercoverage bias because only those attending the concert will have an opportunity to register an opinion. This is nonresponse bias because many who are asked about the ticket tax may choose to not provide a response. This is voluntary response bias because many vocal supporters of the ticket tax may demand to register their opinion.
Answer:
This is undercoverage bias because only those attending the concert will have an opportunity to register an opinion.
Step-by-step explanation:
Undercoverage bias occurs when the sample chosen for a research is not representative of the entire population. Most times when research involving surveys to obtain the opinions of people on a subject matter, the entire population affected by the issue cannot be surveyed. A sample that represents the true population can be used for this research.
In the survey above, the sample that was surveyed was not representative of the entire population of citizens paying taxes on entertainment tickets. The selection process does not represent the true population.
