Step-by-step explanation:
If the student will need to save every month in order to pay off the remaining costs in 10 months, the amount she will need to save per month is $690
Amount and interest
Given the following information from the question
The total cost of fee = $23,500
Amount got as help;
An academic scholarship of $8,200.
Other scholarships and grants of $7.400.
Grandparents pay $1,000
Amount she had = 8200 + 7400 + 1000

In this problem, p is in dollars and x is the number of units.
Find the producer's surplus at market equilibrium for a product if its demand function is p = 121 − [tex]x^{2}[/tex] and its supply function is p = [tex]x^{2}[/tex] + 6x + 65. (Round your answer to the nearest cent.)
The market equilibrium is the point where the demand and supply functions are equal
The producer's surplus at market equilibrium for a product is #105
How to determine the producer's surplusThe functions are given as:
[tex]p = 121 - x^2[/tex]
[tex]p = x^2 + 6x + 65[/tex]
Equate both functions
[tex]x^2 + 6x + 65 = 121 - x^2[/tex]
Collect like terms
[tex]x^2 + x^2 + 6x + 65 - 121 = 0[/tex]
Evaluate the like terms
[tex]2x^2 + 6x -56 = 0[/tex]
Divide through by 2
[tex]x^2 + 3x -28 = 0[/tex]
Expand
[tex]x^2 + 7x - 4x - 28 = 0[/tex]
Factorize
[tex]x(x + 7) - 4(x +7)= 0[/tex]
Factor out x + 7
[tex](x - 4)(x +7)= 0[/tex]
Solve for x
x = 4 or x = -7
The number of units cannot be negative,
So, we have:
x = 4
Substitute 4 for x in [tex]p = 121 - x^2[/tex]
[tex]p = 121 - 4^2[/tex]
p = 105
Hence, the producer's surplus at market equilibrium for a product is #105

Graphing an interger function and finding its range for a given domain
For the function and given domain, the range is {-9,-1,5,7}.
Linear FunctionA linear function can be represented by a line. The standard form for this equation is: [tex]y=ax+b[/tex], for example, y=2x+7.
Domain and RangeThe domain of a function is the set of input values for which the function is real and defined. On the other words, when you define the domain, you are indicating for which values x the function is real and defined.
While the domain is related to the values of x, the range is related to the possible values of y that the function can have.
The equation of this exercise, 2x+1, is a linear equation because it presents the form: ax+b. Thus, you already know that your graph will be a line.
Find values of y for given domain:For this, you should replace -5,-1, 2,3 for x in the equation 2x+1.
For x=-5, [tex]y=2*(-5)+1=-10+1=-9[/tex]
For x=-1, [tex]y=2*(-1)+1=-2+1=-1[/tex]
For x=2, [tex]y=2*(2)+1=4+1=5[/tex]
For x=3, [tex]y=2*(3)+1=6+1=7[/tex]
Therefore, the range is {-9,-1,5,7}
Plot the graphFrom the values x of domain and the values of y calculated previously, plot the points and draw the line. See the image attached.

stabilizes? In other words, how many total iterations occur until the pattern isn't different between generations? You
may use any resources or additional graph paper to determine this number. Type the number of your answer in the
space provided. Example: (Generation 0 + Generation 1 + Generation 2 + Generation 3 + Generation 4) = 5 generations
Answer: ↓↓↓
Step-by-step explanation: Generation time (G) is defined as the time (t) per generation (n = number of generations). Hence, G=t/n is the equation from which calculations of generation time (below) derive.
Jeremy received a basket containing 8 red and 4 green apples.
When he randomly selects and eats two apples from the basket, these are
events.
The probability that both of the apples Jeremy eats are green is
.
Answer:
It is more probable that he pick two red apples than green. Because their are more red apples thank green so the chances of him picking green apples are very slim.
Have a nice day/night!
This is an example of probability without replacement and can simply be done using the formula.
The probability that both apples he ate will be green is 1/12
Probability without replacementThis is done when we pick a value from a data set and does not replace it and hence affects the value of the original data set.

ASpoon is sold at a loss of 47%. If it was sold at 200
Calculate the Cost Price
Answer:
377.36(2decimal places)
Step-by-step explanation:
Solution
First write down all known info about problem
Loss(L) percent:47%
Selling price(SP):200
Cost Price is unknown but CP percent equals 100%(basic percent b'cos it represents the basic cost of the item)
When at a loss, the CP is higher than the SP so subtract the L% from the CP% to get the SP percent...
∴SP% equals CP%-L%
100%-47%:53% ∴SP%:53%
We can simply cross multiply now by saying,
If 53% equals 200
∴100% equals a variable(x)
Cross multiplying,we get:
53x equals (200×100) so dividing both sides by 53,
x equals 377.36(2 decimal places)
Therefore, the CP is 377.36

vertex (-2 , 6)
y = a(x -[-2])² + 6
y = a(x + 2)² + 6
This is passing through (-4,8)
