The graph of the quadratic function can be seen on the image at the end.
How to graph the quadratic function?The only way to graph or sketch a function by hand, is by finding some points on the graph and then connecting them.
To find the points we need to evaluate the quadratic equation.
if x = 0
y = 5*0^2 + 2 = 2
So we have the point (0, 2)
if x = 1
y = 5*1^2 + 2 = 7
So we have the point (1, 7)
if x = -1
y = 5*(-1)^2 + 2 = 7
So we have the point (-1, 7)
And so on, once you have enough points, you can graph them on the coordinate axis and then connect them. The graph of the quadratic equation can be seen on the image at the end.

What is equation?A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.
the equation is
4(8x + 2) = 4(7x + 2 + x)

Martina has been given a list of 5 bands and asked to place a vote. Her vote must have the names of her favorite and second favorite bands from the list. How many different votes are possible?
Answers
Answer:
Step-by-step explanation:
Martina has been given 5 bands and asked to place a vote for her favorite and second favorite bands. The number of different votes possible can be calculated using combinations.
A combination is a way of selecting items from a set, where order does not matter and repetition is not allowed. To find the number of combinations, we can use the formula:
C(n, k) = n! / (k! * (n - k)!)
where:
n is the number of items
k is the number of items being selected
! denotes factorial, which is the product of all positive integers up to that number
Step-by-step, the calculation is as follows:
Determine the number of items and the number of items being selected:
n = 5 (the number of bands)
k = 2 (the number of bands Martina is voting for)
Calculate the number of combinations using the formula:
C(n, k) = n! / (k! * (n - k)!)
C(5, 2) = 5! / (2! * (5 - 2)!)
C(5, 2) = 120 / (2 * 3!)
C(5, 2) = 120 / (2 * 6)
C(5, 2) = 120 / 12
C(5, 2) = 10
So, there are 10 different votes possible for Martina's favorite and second favorite bands from the list of 5 bands.

Graph the image of square CDEF after a dilation with a scale factor of

, centered at the origin.
Answers
Answer:
Step-by-step explanation:
To graph the image of square CDEF after a dilation with a scale factor of 2, centered at the origin, you would need to double the x and y-coordinates of each vertex of the square.
Assuming square CDEF has vertices at (a, b), (a, b + 1), (a + 1, b + 1), and (a + 1, b), the image of the square after the dilation would have vertices at:
(2a, 2b)
(2a, 2b + 2)
(2a + 2, 2b + 2)
(2a + 2, 2b)
So, the side length of the image square would be double the side length of the original square, and its overall shape would be the same.
To graph the image, you would plot each of the new vertices and connect them to form the image square.
The solution is given below.

What are the coordinates of (-5,6) after a dilation of 2 centered at the origin
Answers
Answer:
(-10, 12).
Step-by-step explanation:
A dilation with a scale factor of 2 centered at the origin expands distances from the origin by a factor of 2. If a point in the plane is represented by the coordinates (x, y), then the point obtained by a dilation centered at the origin with scale factor k is represented by (kx, ky).
So, if the original point is (-5, 6), then after the dilation of 2 centered at the origin, the new point is represented by (2 * -5, 2 * 6) = (-10, 12).
So the coordinates of (-5, 6) after a dilation of 2 centered at the origin are (-10, 12).

What is the equation of line?The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.
To find the equation of the line passing through the two points (-2, 4) and (4, 2), we can use the point-slope form of a line. The point-slope form of a line is given by:
y - y₁ = m(x - x₁)
where m is the slope of the line and (x₁, y₁) is any point on the line.
To find the slope of the line, we can use the formula:
m = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) and (x₂, y₂) are the two given points.
Plugging in the values for the given points, we get:
m = (2 - 4) / (4 - (-2))
m = -2 / 6
m = -1/3
Next, we can use one of the given points to write the equation in point-slope form:
y - 4 = -1/3 (x - (-2))
y - 4 = -1/3 x + 2
y = -1/3 x + 6
This is the equation of the line passing through the two given points (-2, 4) and (4, 2).

The billing period is 31 days long. She is planning to purchase $7,400 worth of new kitchen cabinets this billing cycle. She will use her tax refund to pay off her entire bill next month. If she purchases the kitchen cabinets on the last day of the billing cycle instead of the first day, how much would she save in finance charges? Round to the nearest ten dollars.
Answers
If Mrs. Imperiale's credit card has an APR of 13.2%. The amount she would save in finance charges Round to the nearest ten dollars is $80.
What is the amount saved?Finance charge if bought on the first day
Finance charge = (31 × 7400 ÷ 31) × (0.132 ÷ 12)
Finance charge = 7400 × 0.011
Finance charge= $81.40
Finance charge if bought on the last day
Finance charge = (1 × 7400 ÷ 31) × (0.132 ÷ 12)
Finance charge = 238.709677 × 0.011
Finance charge= $2.625
Finance charge = $2.63
Savings = $81.40 - $2.63
Savings = $78.77
Savings = $80 ( Approximately)
Therefore the savings is $80.

Give the domain of
s(x)=6/25-x^2
Answers
Answer: The domain of a function is the set of all possible input values (x-values) for which the function is defined and produces a valid output (y-value).
In this case, the function s(x) = 6/25 - x^2 has no restrictions on the input values for x, so the domain of the function is all real numbers.
Therefore, the domain of the function s(x) = 6/25 - x^2 is:
(-∞, ∞)
This means that the function can be evaluated for any real value of x.

r log a + y log c
Answers
The required r log a + y log c is equivalent to the expression as [tex]r log a + y log c = log (a^r c^y)[/tex].
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The expression r log a + y log c can be simplified using logarithmic properties. Specifically, we can use the rule that says:
[tex]log a^b = blog a[/tex]
Using this rule, we can write the expression as:
[tex]r log a + y log c = log a^r + log c^y[/tex]
Now we can use the rule that says:
log a + log b = log ab
to combine the two logarithms:
[tex]log a^r + log c^y = log (a^r c^y)[/tex]
Therefore, the expression r log a + y log c simplifies to:
[tex]r log a + y log c = log (a^r c^y)[/tex]

If your car gets 24 miles per gallon, how much does it cost to drive 450 miles when gasoline costs $2.70 per gallon?
Answers
Answer:
Cost $50.63
Step-by-step explanation:
To calculate the cost, we need to find out how many gallons of gasoline the car will consume in 450 miles. We can use the formula:
Gallons = Total miles / Miles per gallon
Gallons = 450 miles / 24 miles per gallon
Gallons = 18.75
Next, we multiply the number of gallons by the cost per gallon to get the total cost:
Total cost = Gallons * Cost per gallon
Total cost = 18.75 gallons * $2.70 per gallon
Total cost = $50.63
So, it will cost $50.63 to drive 450 miles when gasoline costs $2.70 per gallon and your car gets 24 miles per gallon.
