Answer:
A
Step-by-step explanation:
The profit for selling x pairs of shoes is given by:
[tex]P(x)=-4x^2+32x-39[/tex]
And we want to determine the number of pairs that needs to be sold in order to maximize profit.
Since the function is a quadratic with a negative leading coefficient, the maximum profit will occur at its vertex point. The x-coordinate of the vertex of a quadratic is given by:
[tex]\displaystyle x=-\frac{b}{2a}[/tex]
In this case, a = -4, b = 32, and c = -39. Substitute and evaluate:
[tex]\displaystyle x=-\frac{(32)}{2(-4)}=\frac{32}{8}=4[/tex]
So, in order to maximize profit, only four pairs of sohoes should be sold.
Our answer is A.

Answer:
A reflection about y=x
Step-by-step explanation:
The 4 transformations are
TranslationRotationReflectionDilationLet eliminate which ones won't work.
A translation wouldn't flip the triangle in a different direction after translating it so we won't translate it.
A dilation changes the length for the triangle but the triangles are congruent so we won't dilate it.
A rotation about the orgin wouldn't work nor a specific point so a rotation isnt going to work.
A reflection will work so what will we reflect about.
Some corresponding coordinates are5,6 and 7,61,6 and 7,23,8 and 9,4.A reflection makes a reflected point equidistant from the line of reflection and their original point is equidistant from line of reflection.
So let find the midpoint of all the points and find a line where all of them are on.
The midpoint respectively are
6,64,46,6Let find the line that includes both these points.
[tex] \frac{6 - 4}{6 - 4} = \frac{2}{2} = 1[/tex]
So this means our slope is x. The y value corresponds with the x value so the answer is
[tex]y = x[/tex]
So the answer is
"A reflection about y=x

What is factor?
A factor of polynomial P(x) is any polynomial which divides evenly into P(x).
How to find the solution for a polynomial?For finding the factor of a polynomial we will perform following steps:
If f(x) is any polynomial then substitute f(x) = 0.Then factorize the given polynomial by splitting the middle term. Then solve for x.According to the given question.
We have a cubic polynomial [tex]x^{3} -4x^{2} +ax -2a[/tex]
Also, x - 3a is a factor of the given polynomial.
⇒ [tex]x - 3 = 0[/tex]
⇒[tex]x = 3[/tex]
⇒ 3 is the one solution of the given cubic polynomial.
If 3 is the one solution of the cubic polynomial then it must satisfy the equation (i).
So, substitute the value of x in the given polynomial.
[tex](3)^{3} -4(3)^{2} + a (3) - 2a = 0[/tex]
⇒[tex]27 -4(3)^{2} +a(3) -2a=0[/tex]
⇒[tex]27 - 36 + 3a - 2a= 0[/tex]
⇒[tex]-9 + a = 0[/tex]
⇒ [tex]a = 9[/tex]
Therefore, the value of a is 9.

−2(−4+1)=3+8
-2({\color{#c92786}{-4x+1}})=3x+8−2(−4x+1)=3x+8
2)
Distribute
−2(−4+1)=3+8
{\color{#c92786}{-2(-4x+1)}}=3x+8−2(−4x+1)=3x+8
8−2=3+8

What’s the answer and give an explanation.
Answer:
14 = x and 2.5 = y
Step-by-step explanation:
For ABCD - the top is 8 and the sides are 11. 11 minus 8 is 3. 11 plus 3 equals 14, that’s x.
For GHIJ - the bottom is 8 and both sides are 5.5. So 8 minus 5.5 is 2.5. That’s y.
Q10/ scale factor of polygon ABCD to polygon GHIJ = 11/5.5 = 2
Q11/ scale factor of polygon GHIJ to polygon ABCD = 1:2
Q12/ x = 8 × 2 = 16
y = 8 / 2 = 4
Q13/ ABCD ⇒ label x as 16, y as 4
GHIJ ⇒ label HI line to 5.5
Q14/ ratio = 46 : 23

The RAND() function in Excel returns a pseudo-random number between 0 and 1. If you enter this function into 1000 cells (i.e. enter the formula in one cell and copy it to 999 other cells), approximately how many of these cells will contain values less than or equal to 0.2?
a. A number relatively close to 1.
b. A number relatively close to 10.
c. A number relatively close to 100.
d. A number relatively close to 500.
e. A number relatively close to 1000.
Answer:
c. A number relatively close to 100.
Step-by-step explanation:
Given
[tex]Range: 0 \to 1[/tex]
[tex]N =1000[/tex] --- i.e. the cells
Required
Number of cells that contains less than or equal 0.2
Less than or equal 0.2 means that the numbers are approximately 20% of the whole distribution
So, to calculate the number (n) of these cells, we do the following computation
[tex]n = 20\% * N[/tex]
[tex]n = 20\% * 1000[/tex]
[tex]n = 200[/tex]
200 is closer to 100 than 500. Hence, (c) is correct

Answer:
Vertical
Step-by-step explanation:
<AGB and <EGD are vertical angles because they are vertically opposite from each other since they were created from two lines crossing.
-You know that they aren't adjacent because they aren't next to each other and don't share a side or a vertex.
-They can't be supplementary because they don't add up to 180 degrees
-They can't be complementary because they don't make up 90 degrees
Find the area of the shaded religion.
Giving brainliest! <3
Answer: 240 feet
Step-by-step explanation:
What you could do is find the area of the whole thing. 12x25 is 300. Then, you can find the area of the white part, which is 60, because you multiply 12x5. then, you would subtract 60 to 300, which would get you to 240 feet.
Answer:
The answer is : 240cm² for the shaded part
The unshaded part is = 60cm²
The whole rectangle = 300cm²
Step-by-step explanation:
Area is = WL
W = width (while the) L= length
The Area = 25 × 12 = 300
The area of the full rectangle is = 300
The unshaded part is = 5 × 12 = 60
So the shaded part is = 300 - 60 = 240cm²
[tex]so \: the \: answer \: is \: = 240cm^{2} [/tex]

How to write the fraction 34/100 as a decimal
an investment of Rs 100000 is made which on interest at the rate of 8% per year if the interest is compounded continuously to what value with investment grow in 7 year period
Answer:
A = $174,742.21
A = P + I where
P (principal) = $100,000.00
I (interest) = $74,742.21
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 8/100
r = 0.08 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 100,000.00(1 + 0.08/12)(12)(7)
A = 100,000.00(1 + 0.006666667)(84)
A = $174,742.21
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $100,000.00 at a rate of 8% per year compounded 12 times per year over 7 years is $174,742.21.
A density curve for all the possible ages between 0 years and 50 years is in the shape of a triangle. What is the height of the triangle? O A. 0.04 O B. 0.02 O c. 0.01 O D. 0.08 SUBMIT
Answer:
0.04
Step-by-step explanation:
For a density curve, total area = 1
Probability lies in between 0 and 1
The Area of triangle :
Area = 1/2 base * height
Base = 0 - 50 = 50
Area = 1
Hence,
1 = 1/2 * 50 * h
1 = 50h / 2
2 = 50h
h = 2 / 50
h = 0.04
