Answer:
p= 9
Step-by-step explanation:
you can rewrite the equation as 7p = 63 if that makes more sense for you
then divide both sides by 7
you get 9

Suppose a number is chosen at random from the set {0,1,2,3,...,497}.
What is the probability that the number is a perfect cube?
===========================================================
Explanation:
Cube values in the set {0,1,2,3,...} until we reach a result larger than 497
0^3 = 01^3 = 12^3 = 83^3 = 274^3 = 645^3 = 1256^3 = 2167^3 = 3438^3 = 512We stop here because 512 is larger than 497.
Or you could note that [tex]\sqrt[3]{497} = 497^{1/3} \approx 7.921[/tex] helping us see that we stop at 8.
The list of nonnegative perfect cubes less than 497 is {0,1,8,27,64,125,216,343}
There are 8 items in that set out of 498 items in the set {0,1,2,3,...,497}
So the probability of getting a perfect cube is 8/498 = 4/249

Anna is writing a computer game program. She needs to “move” a square 2 units to the left and 3 down by applying a translation rule to the coordinates of the vertices. The square is aligned with the coordinate axes with one corner of the pre-image square at the origin and the diagonally opposite corner at (4,4). After the transformation what will be the coordinates of the image of each of the four vertices.
A. Write the transformation rule for this particular translation. Use the format given in class.
B. Show the math work that is used to calculate the new coordinates mathematically. State the final coordinate pairs. There should be four pairs of coordinates.
C. Graph, sketch, or draw a picture of the situation. Sketch (on a grid) the pre-image and image of the square. Be sure to include the line segments that form the sides of the square. You MUST label all eight coordinate pairs on your sketch or graph. (You may use Desmos or graph paper for this part. You may even include a link to your Desmos graph.)
The original square has one verticles at the origin, which is at (0,0), and the opposite corner at (4,4), we draw the square show below:
The transformation is moving each verticles 2 unit left and 3 units down.
In term of x-axis translation (horizontal transformation), we move 2 units left or, -2.In term of y-axis translation ( vertical transformation), we move 3 units down, or -3.The tranformation rulw can be written as:
[tex]x = x - 2 \\ y = - 3[/tex]
From the graph shown above, we write the 4 cordinate pairs:
(0,0)
(4,0)
(4,4)
(0,4)
Aplying the transformation rule, we subtract 2 from x cordinate and subtract 3 from each y cordinate.
The new transformed cordinate are:
(0,0) >>>>>> (0-2, 0-3) >>>>>>> (-2, -3)
(4,0) >>>>>> (4-2, 0-3) >>>>>>> (2, -3)
(4,4) >>>>>> (4-2, 4-3) >>>>>>> (2, 1)
(0,4) >>>>>> (0-2, 4-3) >>>>>>> (-2, 1)
We name the first four cordinates A,B,C and D, respectively.

WidgCo is a company that produces and sells widgets. Let p denote the price per widget (measured in dollars), and let x be the monthly demand for widgets. WidgCo's marketing department determines that p and x are related by the following demand equation: p(x) = 211 − 5x. The cost of producing x widgets is given by C(x) = 1,401 + 16x. Construct the revenue function, R(x). Find the production level that will result in the maximum revenue. Find the maximum monthly revenue. Enter your answer to part c in the box below. Round your answer to the nearest cent.
Answer:
The answer to this question can be defined as follows:
i) [tex]\bold{p(x)= -5x^2+ 217x- 1,401} \\[/tex]
ii) x=22 units
iii) Maximum profit: 953.45
Step-by-step explanation:
Given value:
p(x) = 211 − 5x \\
C(x) = 1,401 + 16x
The formula for calculating the profit function value:
[tex]\to \bold{P(x)= xp(x) - C(x)}[/tex]
[tex]= x(211-5x)- 1,401 + 16x\\\\= 211x -5x^2-1,401+16x\\\\= -5x^2+ 217x- 1,401 \\[/tex]
The formula for calculating the value for maximum profit:
[tex]p'(x) = - 10x + 217 =0[/tex]
[tex]217= 10x\\\\x= \frac{217}{10}\\\\x= 21.7[/tex]
So, the production level is 22 units
Maximum profit:
[tex]\to p(21.7)= - 5 (21.7)^2+217 (21.7) -1,401\\\\[/tex]
[tex]=-5 (470.89) +217 (21.7) -1,401\\\\=-2354.45+ 4708.9-1,401\\\\= 953.45[/tex]
The maximum monthly revenue of WidgCo is; $489
We are given;price function; p(x) = 211 - 5x
Cost function; C(x) = 1401 + 16x
We know that revenue would be gotten by the formula;Revenue = number of units sold × price per unit
Thus;
R(x) = x(211 - 5x)
Expanding this gives;
R(x) = 211x - 5x²
Maximum revenue will be the revenue for the number of widgets when R'(x) = 0. Thus;R'(x) = 211 - 10x
At R'(x) = 0, we have;
211 - 10x = 0
x = 211/10
x = 21.1
x ≈ 21 widgets
Thus;Maximum Revenue is;
R(20) = 195(21) - 1401 - 5(21)²
R(20) = $489

Two rhombuses with the same side lengths are always congruent ?
Answer:
False
Step-by-step explanation:
A rhombus is a quadrilateral with
1. all side length equal
2. opposite side parallel
3. opposite angles are congruent.
______________________________________
If there are two rhombus with same side length ,
conditions so that they must be always congruent.
1. Side length must be equal
2. corresponding angles to equal sides must also be equal.
It is possible that the sides of two rhombus will be same
but their angles can differ and hence the two rhombus may or may not be congruent.
Thus,
Two rhombuses with the same side lengths are always congruent
given statement is false

A recipe for homemade modeling clay includes 1/3 cup of salt for every cup of water. If there are 6 cups of salt, how many gallons of water are needed?
Answer:
Step-by-step explanation:
If for a cup of water, 1/3 cup of salt is needed, to get the number of gallons of water needed for 6 cups of salt, we will use the following equation;
1/3 cup of salts = 1 cup of water
6 cups of salt = x cups of water
cross multiply
1/3 * x= 6*1
x/3 = 6
multiply both sides by 3
x/3 * 3 = 6*3
x = 18
Hence 6 cups of salt will need 18 gallons of water

find the slope, vertical and horizontal intercept of (2,9) and (4,3)
Answer:
Slope: -3
Vertical Intercept (y-intercept): 15
Horizontal Intercept (x-intercept): 5
Step-by-step explanation:
[tex]\frac{3-9}{4-2}[/tex] = [tex]\frac{-6}{2}[/tex] = -3
then we put the slope into point slope form.
y-9=-3(x-2)
in order to find the x-intercept, we need to make the y value 0.
-9=-3(x-2) ⇒-9=-3x+6 then subtract 6 from both sides.
-15=-3x divide both sides by -3 to get 5, the x-intercept.
in order to find the y-intercept, we need to make the x value 0.
y-9=-3(-2) ⇒y-9=6 then add 9 to both sides.
y=15

Functions hand k are inverse functions, and both are defined for all real numbers.
Using this relationship, what is the value of each function composition?
(h o k)(3)=
(K o h)(-46)=
Answer:
(h o k)(3)= 3
(K o h)(-4b)= - 4b
Step-by-step explanation:
Composition of a function and its inverse function returns the input
(h o k)(3)= 3
(K o h)(-4b)= - 4b
Answer:
[tex](h\circ k)(3)=3[/tex]
[tex](k\circ h)(-4b)=-4b[/tex]
Step-by-step explanation:
Remember that for two functions to be inverses, the following must be true:
[tex]h(k(x))=k(h(x))=x[/tex]
Since we know they are indeed inverses, they are true.
So, whatever input we put in, we'll just get it back out again.
So, for our first problem:
[tex](h\circ k)(3)[/tex]
We can rewrite this as:
[tex]=h(k(3))[/tex]
We can imagine our x being 3 here.
Therefore, using the above identity, we can conclude that:
[tex]h(k(3))=3[/tex]
For our second example, the same thing:
[tex](k\circ h)(-4b)[/tex]
This is the same as saying:
[tex]k(h(-4b))[/tex]
Again, using the above property, we can imagine our x is -4b. So, this will be equivalent to:
[tex]k(h(-4b))=-4b[/tex]
And we're done!
An Integrated Circuit (IC) chip is declared as "good" if it passes the quality acceptance test. Otherwise, the chip is declared as "bad". A mechanical machine produces two IC chips in pairs. Tests show that the first chip is good with probability 3/5. When the first chip is good, the probability that the second chip is good is 4/5. When the first chip is bad, the probability that the second chip is good is 2/5. a) What is the probability that both chips are good? b) What is the probability that both chips are bad? c) What is the probability that exactly one chip is good?
Answer:
a) The probability of both chips being good = 0.48
b) The probability of both chips being bad = 0.24
c) The probability of one chip being good = 0.60
Step-by-step explanation:
Probability of first chip being good = 3/5 = 0.60
Probability of second chip being good = 4/5 = 0.80
Probability of first chip being bad = 0.40 or 2/5 (1 - 3/5)
Probability of second chip being good if the first is bad = 2/5 = 0.4
Therefore, the probability of it being bad = 0.60 (1 - 0.40)
For both chips to be good, the probability = 0.60 * 0.80 = 0.48
For both chips to be bad, the probability = 0.60 * 0.40 = 0.24
