The answer is option A 34 units.
We need to count the distance between the points and then add them to get the perimeter.
L and M are 5 units away, as well as X from J
L and X are 12 units away, as well as M from J
Now we can add the distances:
5 + 5 + 12 + 12 = 34
THen the perimeter is 34 units

with Product (choose one)
Answers
The correct answer is Product (B) performed worse in the study because 90% failed to get relief with this product, whereas only 20% failed to get relief with Product (A).
How to solve study based problems?
In mathematics, the study based problems are analyzed with the given percentage data. The calculation is based on statistical result and comparison results.
According to the question, the detailed study of pain relievers states that the 20 people were given Product A, and all but 4 experienced relief. And in the same study, 50 people were given Product B, and all but 6 experienced relief.
Let us assume total number of people be 100.
For the Product B, only 6 people got the relief that means out of 100 people only 12 got the relief which means Product B is performed worst.
Similarly, for the Product A, only 4 people got relief that means out of 100 people almost 20 people got the relief which means it is better than the product B.
Hence, the correct answer is Product (B) performed worse in the study because 90% failed to get relief with this product, whereas only 20% failed to get relief with Product (A).

Vladimir is looking to retire in 10 years. He has a plan to put $25,000 into an investment today that earns interest at a fixed amount per year. What would be a reasonable domain and range for a function modeling the total amount of the investment, including interest?explain your answer
Answers
If Vladimir is looking to retire in 10 years and he has planned to put $25,000 into an investment from today itself, that earns interest at a fixed amount per year, considering the rate of interest to be (R%) per annum, the domain and range for a function modeling the total amount of the investment, including interest are as follows:
Domain [X = {0 ≤ years ≤ 10}]
Range (total amount), [Y = {$25,000 ≤ Y ≤ 25,000( 1 + 10R)}]
As per the question statement, Vladimir is looking to retire in 10 years and he has planned to put $25,000 into an investment from today itself, that earns interest at a fixed amount per year, and since there is no information about the rate of interest of that investment, we are considering the rate of interest to be (R%) per annum.
We are required to determine the domain and range for a function modeling the total amount of the investment, including interest using the question statement mentioned data and our assumptions.
Since the starting principal amount, say P is $25,000, given,
Time of investment, say T is 10 years, also given,
And considering the interest rate per year to be R (%),
Then after 10 years, the total amount Vladimir has is [25000( 1 + xR)].
Where, the Domain (No. of years ) is [X = {0 ≤ years ≤ 10}]
And Range (total amount), [Y = {$25,000 ≤ Y ≤ 25,000( 1 + 10R)}]
Domain of a Function: In mathematics, the domain of a function is the set or group of inputs that is accepted by the function.Range of a Function: In mathematics, the range of a function is the set or group of outputs produced by the function using values from its domain.To learn more about Domain and Range of a Function, click on the link below.

One part is a constant and the other varies directly as the connection time t minutes. When the monthly service charge is $230, the connection time is 100 minutes. When the monthly service charge is $290, the connection time is 130 minutes.a) Express S in terms of t.b) Find the value of the connection time t when the monthly service charge$S is $330.
Answers
Since the monthly charge S is made from 2 parts,
A constant part, let it b
A part depends on a direct relationship between it and the time t
Then the form of S should be
[tex]S=mt+b[/tex]Where:
m is the rate of change
b is the constant amount
Since S = 230 at t = 100
Since S = 290 at t = 130
Substitute them in the equation above to make 2 equations of m, b and solve them
[tex]\begin{gathered} 230=100m+b\rightarrow(1) \\ 290=130m+b\rightarrow(2) \end{gathered}[/tex]Subtract equation(1) from equation (2) to eliminate b
[tex]\begin{gathered} (290-230)=(130m-100m)+(b-b) \\ 60=30m \end{gathered}[/tex]Divide both sides by 30 to find m
[tex]\begin{gathered} \frac{60}{30}=\frac{30m}{30} \\ 2=m \\ m=2 \end{gathered}[/tex]Substitute m in equation (1) by 2 to find b
[tex]\begin{gathered} 230=100(2)+b \\ 230=200+b \end{gathered}[/tex]Subtract both sides by 200
[tex]\begin{gathered} 230-200=200-200+b \\ 30=b \\ b=3 \end{gathered}[/tex]a) The equation of S is (substitute m by 2 and b by 30)
[tex]S=2t+30[/tex]b) Since the monthly fee is $330, then
S = 330
Substitute it in the equation to find t
[tex]330=2t+30[/tex]Subtract 30 from both sides
[tex]\begin{gathered} 330-30=2t+30-30 \\ 300=2t \end{gathered}[/tex]Divide both sides by 2 to find t

Theater Tickets. The El Portal Center for the Arts in North Hollywood, California, holds a maximum of 400 people. The two balconies hold 94 and 91 people each; the rest of the seats are at the stage level. Solving the equation x + 94 + 91 = 400 will give you the number of seats on the stage level.
Answers
So first of all we have to solve this equation:
[tex]x+94+91=400[/tex]We can perform the operation 94+91=185 so we get:
[tex]x+185=400[/tex]And we can substract 185 from both sides of the equation:
[tex]\begin{gathered} x+185-185=400-185 \\ x=215 \end{gathered}[/tex]Then the answer to part a is 215.
Now that we have the number of seats on the stage level we can find the max amount of money the theater can bring in. This will be given by the total number of seats in the stage level multiplied by the cost per ticket for these seats plus the total number of seats in balconies (185) multiplied by the cost per ticket for these seats. Then we get:
[tex]215\cdot30+185\cdot25=11075[/tex]Then the max amount of money the theater can bring in for a show and answer to part b is $11075.

The account earns an 8% annual interest
r = 8% = 8/100 = 0.08
The balance is for 4 years
t = 4
For no 1 it is annual, then
n = 1
Substitute these values in the rule above

Solve this eq. by putting the values [-5, 10],
let, interval [-5, 10] = [a, b]
Then solve for g(a) and g(b), we know g(a) = g(-5),
g(-5) = log₂(-5+6) - 3
= log₂1 - 3
= 0 - 3
g(-5) = -3
Now, for g(b) = g(10)
g(10) = log₂(10+ 6) - 3
= log₂16 - 3
= 4 - 3
g(10) = 1
Now put these values in average rate formula,
Average rate = (g(b) - g(a)) / (b - a)
= (1 - (-3)) / (10 - (-5))
= (1 + 3) / (10 + 5)
= 4 / 15
Therefore, the average rate is 4/15 i.e, option(C)

to determine the product between the 2 numbers we must write both numbers in scientific notation
[tex]800.5=8.005\cdot10^2[/tex]now we multiply both number without the tenth potency.
[tex]8.005\cdot2=16.01[/tex]now we add the tenth potencies
[tex]\begin{gathered} 16.01\cdot10^{6+2} \\ 16.01\cdot10^8 \end{gathered}[/tex]now we move 1 decimal place more to the left to make the number between 0 and 9.9
[tex]16.01\cdot10^8=1.601\cdot10^9[/tex]
