If you shift the linear parent function, f(x)=x, down 7 units what is the equation of the new function
Answers
1- You have that following parent function (the most basic function of the linear functions) given in the problem above:
f(x)=x
2- When you graph this parent function, you obtain the graph shown in the figure attached.
3- If you shift the linear parent function 7 units down, you have the following new function:
f(x)=x-7
4- The graph of the new function is shown in the second figure attached.
The answer is: f(x)=x-7
f(x)=x-7 is indeed the correct answer.just got it right

Kevin owes $4,645 on a credit card with a 19.7% interest rate compounded monthly. What is the monthly payment he should make in order to pay off this debt in 12 months, assuming he does not charge any more purchases with the card?
$387.08
$84.34
$429.62
$1,034.65
**Please help with steps too, please.
Answers
Alternatively, and somewhat more slowly, you can make use of the amortization formula.
A = P(r/n)/(1 -(1 +r/n)^(-nt))
where A is the monthly payment,
P is the current balance (4645),
r is the annual rate (.197),
n is the number of compoundings per year (12), and
t is the number of years (1).
Filling in the numbers, you have
A = 4645*(.197/12)/(1 -(1 +.197/12)^-12)
A ≈ 429.62 . . . . . corresponds to the 3rd choice

3.Find the center and the radius for the circle, given the equation:
x^2-14x+y^2+8y=16
Answers
we know that
All circles are similar. Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilations) can be found that map one figure onto another. In our attempt to prove all circles are similar, a translation and a scale factor (from a dilation) will be found to map one circle onto another

a) ∡BAD=128°-----------> by central angle
b) ∡BCD
The inscribed angle measures half of the arc it comprises.
so
∡BCD=128°/2----> 64°
c) ∡BED
The measure of the external angle is the semi difference of the arcs that it covers.
arc BCD=360°-128°=232°
∡BED=(1/2)*[232-128]-----> 52°
d) What is the relationship between BA and BE?

Luis bought stock at $66.80. The next day, the price increased $13.85. This new price changed by −2 3 /4 % the following day. What was the final stock price, rounded to the nearest cent? ?
Answers
1) Luis bought stock at ---------------> $66.80
2) The next day, the price increased $13.85--------> $66.80+$13.85=$80.65
3) This new price changed by −2 3 /4 % the following day
2 3/4%----> (2*4+3)/4----> 11/4 %----> 2.75%
so
(100%-2.75%)-----> 97.25%
the final stock price is $80.65*0.9725-----> $78.43
the answer is
$78.43

Juan had $5.25 in nickels and quarters. if he had 15 more nickels than quarters, how many quarters did he have?
Answers
First, let us say x is the number of nickels Juan had, and y is the number of quarters Juan had.
Now, we all know that a nickel is worth 5 cents and a quarter is worth 25 cents. The given said Juan had a total amount of nickels and quarters equal to $5.25 and that there should be 15 more nickels than quarters - we need a second model: $5.25 = $0.05x+$0.25y, but x = y+15 => $5.25 = $0.05(y+15)+$0.25y. Simplifying, we have $5.25 = $0.05y+$0.25y+$0.75 or $0.3y+$0.75.
Isolating the unknown, we have $5.25-$0.75 = $0.3y, or $4.50 = $0.3y.
Divide both sides by $0.3, we have y = 15. Therefore, x = 15+15 or 30.
Check the solution, 30($0.05)+15($0.25) = $5.25.
Therefore, Juan had 15 quarters.
Juan had 15 quarters. To solve this, we created a system of equations representing the total value of the coins and the relationship between the number of nickels and quarters. Calculations led to the conclusion that there were 15 quarters in total.
The question requires us to solve a system of equations to find out how many quarters Juan had if he had $5.25 in nickels and quarters, with 15 more nickels than quarters. Let's denote the number of quarters as q and the number of nickels as n. Remember, a quarter is worth $0.25 and a nickel is worth $0.05.
Based on the given information, we can establish the following equations:
0.25q + 0.05n = $5.25 (the total value equation)n = q + 15 (the number of coins equation)We can substitute the second equation into the first to find the value of q.
0.25q + 0.05(q + 15) = $5.25
Solving for q:
0.25q + 0.05q + 0.75 = $5.25
0.30q + 0.75 = $5.25
0.30q = $4.50
q = $4.50 / 0.30
q = 15
Therefore, Juan had 15 quarters.

How could the relationship of the data be classified? scatter plot with points scattered going up to the right
A fairly strong positive correlation
A fairly strong negative correlation
A fairly weak negative correlation
Answers
Answer:
The correct answer is A. A fairly strong positive correlation
Step-by-step explanation:
Scatter Plot : A graph of plotted points that show the relationship between two sets of data.
Now, the points of the scatter plot are going up this shows the increase in the data points so we can say the correlation is positive.
Now, the direction of the scatter plots is to the right. So, we can say that the correlation is strong correlation.
Hence, the correct answer is A. A fairly strong positive correlation
Answer:
the Correct Option is A : fairly strong positive correlation
Step-by-step explanation:
Scatter Plot is a graph that is graphed using points and which shows the relationship between two sets of data. Only used to show correlation.
As given the points of the scatter plot are going up this implies the increment in one set of data with respect to other so we can say here correlation is positive. And the direction of the scattered points is to the right. So, it reflects that the correlation is strong correlation.
Thus, the Correct Option is A : fairly strong positive correlation
What is cos (x)?
A) 48/58
B) 58/48
C) 26/58
D) 58/26
Answers
In order to solve for the Cos(x), you need to find the missing side. You can do that by finding the Sin(x) first and then the Cos of x or you can just use the Pythagorean theorem. I'm going to do the latter.
Formula
a^2 + b^2 = c^2
Givens
a = ???
b = 32
c = 58
Sub and solve
a^2 = ???
b^2 = 1024
c^2 = 3364
a^2 + 32^2 = 58^2
1024 + a^2 = 3364 Subtract 1024 from both sides.
a^2 = 3364 - 1024
a^2 = 2340 Take the square root of both sides.
sqrt(a^2) = sqrt(2340) Break a into its prime factors.
a = sqrt(2 * 2 * 5 * 3 * 3 * 13)
Rule
For every pair of equal factors, one can be brought outside the root sign and the other is discarded.
a = 2 * 3 * sqrt(5*13)
a = 6 sqrt(65)
The cos of an angle = opposite / hypotenuse.
Cos(x) = 6*sqrt(65) / 58 <<<<< This should be the answer
If you are offered choices, you should list them
Another choice would be 6*8.0623 / 58 = 0.8340 <<<<< Answer

A rhombus has diagonals 500 yd and 800 yd in length. Find the area in square miles.
Answers
To find the area of a rhombus with diagonals of 500 yards and 800 yards, use the formula (d1 * d2) / 2 and convert the result to square miles.
Given: The diagonals of the rhombus are 500 yards and 800 yards.
Formula: The area of a rhombus can be calculated using the formula: Area = (d1 * d2) / 2, where d1 and d2 are the diagonals of the rhombus.
Calculation: Area = (500 * 800) / 2 = 200,000 square yards.
Conversion: To convert square yards to square miles, divide the area by 3,097,600 (number of square yards in a square mile).
Final Result: The area of the rhombus is approximately 0.0646 square miles.
