What is the value of R? (Assume R > 0)
R/4=36/R
A)8
B)9
C)12
D) 20
The value of R is 12.
What are square roots?A value that yields the original number when multiplied by itself is known as the square root of a number. The square root is a backwards technique for figuring out a number. Thus, squares and square roots are connected ideas.
Given R/4 = 36/R
multiply both sides by R
R/4 x R = 36/R x R
R²/4 = 36
multiply both sides by 4
R²/4 x 4 = 36 x 4
R² = 144
so R = √144
R = 12
Hence R = 12 for given condition.

If (x,2) is a solution to the equation -2x+4y=-8, what is the value of x
Answer:
x=8
Step-by-step explanation:
-2x+4y=-8
Let y = 2
-2x+4*2=-8
-2x+8=-8
Subtract 8 from each side
-2x+8-8=-8-8
-2x=-16
Divide by -2
-2x/-2 = -16/-2
x = 8

Order 0.5, -1/7, -0.2, and 1/3 from least to greatest.
Hey there! I'm happy to help!
Let's convert the decimals to fraction form.
0.5=5/10=1/2
-1/7
-0.2= -2/10= -1/5
1/3
We know that the bigger the number in the denominator, the smaller the fraction is if the numerators are all the same.
First off, we have the negative numbers which are smaller than the other numbers. We have -1/7 and -1/5. We know that the 1/5 is a bigger fraction, but it is negatively bigger, so that is going to be the lesser number.
-1/5, -1/7
And with our bigger ones, we have 1/3 and 1/2. 1/2 is the bigger number here, so that will be the last one. Let's also be sure to convert back to our original forms! Here is our order :
-0.2, -1/7, 1/3, 0.5

Answer:
g(x) = (x -3)² -6
Step-by-step explanation:
You know that a function f(x) is translated h units to the right when x is replaced by x-h.
g(x) = f(x-h) . . . . . translated h units right
You also know that a function f(x) is translated k units up when k is added to the function value.
g(x) = f(x) +k . . . . . translated k units up
__
Here, we want to translate f(x) 3 units right and 6 units down. Using the above relations, we will get ...
g(x) = f(x -3) -6
Using the given definition of f(x), this becomes ...
g(x) = (x -3)² -6

Jerimiah records lap times at the track meet on Saturday. He records a time of 85 seconds for Jennifer's lap, but she really completed the lap in 84.25 seconds.
What is the approximate percentage of error in Jerimiah's measure?
Answer:
I'm not sure. What I would do, though, is find the difference of the two times and then find the percentage of that within the original time. So the difference is .75. So the percentage would be .25%. Just an educated guess.
Where is the error in the solution below? Explain what the error is and solve the equation correctly. Be sure to check your answer.
Answer:
The error in the question is that in the second line, both sides are not multiplied by x. This causes an imbalance in the equation.
Step-by-step explanation:
[tex]\frac{5}{x}= x-4[/tex]
Multiply both sides by x.
[tex]x(\frac{5}{x}) = x(x-4)[/tex]
[tex]5= x^{2} -4x[/tex]
Subtract 5 from the equations.
[tex]x^{2} -4x-5=0[/tex]
Factorise the equation (Quadratics)
[tex](x-5)(x+1)=0[/tex]
Null Factor Law
[tex]x=5[/tex] or [tex]x=-1[/tex]
Here, we have to go through the equation and correct it:
Starting equation: 5/x = x - 4
Multiply both sides by x:
x * (5/x) = x * (x - 4)
[tex]5 = x^2 - 4x[/tex]
Move all terms to one side to set up a quadratic equation:
[tex]x^2 - 4x - 5 = 0[/tex]
Now, we have a quadratic equation that needs to be solved.
We can solve this quadratic equation using factoring, completing the square, or the quadratic formula.
In this case, let's use factoring:
(x - 5)(x + 1) = 0
This gives you two possible solutions:
x - 5 = 0 --> x = 5
x + 1 = 0 --> x = -1
So, the correct solutions for the equation 5/x = x - 4 are x = 5 and x = -1. The error in your solution was in the step where you multiplied by x; you didn't distribute x properly to both terms on the right side of the equation.
This causes an imbalance in the equation.

The profitability, P, of a popular restaurant franchise can be modeled by the function P (t) = t4 – 9t3 + 24t2 – 20t, where t is the number of months since the restaurant opened. How many months after the franchise opens will it begin to show a profit?
5 months
3 months
2 months
1 month
Replace t with the months given as choices to see which one gives a positive value as an answer.
P(1) = 1^4-9(1)^3 + 24(1)^2-20(1) = -4
P(2) = 2^4-9(2)^3+24(2)^2-20(2) = 0
P(3) = 3^4 -9(3)^3+24(3)^2-20(3) = -6
P(5) = 5^4-9(5)^3+24(5)^2-20(5) = 0
P(6) = 6^4-9(6)^3+24(6)^2-20(6) = 96
It shows a profit in month 6 so it would start showing a profit in month 5.
The answer is 5 months
