Answer:
(-2, -4)
Step-by-step explanation:
Let's remember how to calculate the vertex of a parabola:
If we have the equation of the parabola given in the form y = ax^2 + bx + c, the x-coordinate of the vertex is x = -b/2a. For the y-coordinate we just replace the x of the equation with -b/2a and do the calculation.
In this case, a = 1, b = 4, c = 0.
The x-coordinate of the vertex is x = -4/2*1 = -2
The y-coordinate is y = (-2) ^2 + 4*(-2) = 4 - 8 = -4
Therefore, the vertex is (-2, -4)

Nick’s parents purchased their first home in the 1980’s with a 30-year mortgage at 19.5%.
Final answer:
Using the formula for a fixed-rate mortgage payment, the monthly mortgage payment for Nick's parents, who bought a home for $125,000 with a 30-year mortgage at 19.5%, is calculated to be $2,037.40, making the answer A. $2,037.40.
Explanation:
To calculate the monthly mortgage payment for Nick's parents, who purchased their first home with a 30-year mortgage at 19.5% interest, we need to use the formula for a fixed-rate mortgage payment. The formula is:
M = P[r(1+r)ⁿ]/[(1+r)ⁿ⁻¹]
Where:
M is the total monthly mortgage payment.P is the principal loan amount.r is the monthly interest rate (annual rate divided by 12 months).n is the number of payments (loan term in years multiplied by 12 months).For this calculation:
P = $125,000r = 19.5% annual interest rate, which is 0.195/12 per month.n = 30 years x 12 months = 360 payments.We insert these numbers into our formula:
M = $125,000[0.195/12(1+0.195/12)³⁶⁰]/[(1+0.195/12)³⁶⁰⁻¹]
After calculating, we find that the monthly mortgage payment (rounded to two decimal places) would be $2,037.40.
Therefore, the answer is A. $2,037.40.

A car salesman earns 2% commission on all of his sales. If he needs to make $3,000 a month for his living expenses, what total dollar amount must he sell to make that in commission each month?
The total dollar amount he must sell to make that in commission each month is $150000.
What is percentage?In mathematics →
a percentage is a number or ratio expressed as a fraction of 100.it is often denoted using the percent sign "%".Given is that a car salesman earns 2% commission on all of his sales. He needs to make $3,000 a month for his living expenses,
Assume that the total dollar amount he must sell to make that in commission each month is ${x}. Then, we can write -
3000 = 2% of {x}
3000 = (2/100) × {x}
{x} = (3000 x 100)/2
{x] = 300000/2
{x} = 150000
Therefore, the total dollar amount he must sell to make that in commission each month is $150000.

the volume of a prism is:
A. The area of the base times the area of the side.
B. The area of the base times the perimeter of the base.
C. The perimeter of the base times the height.
D. The area of the base times the height of the prism
Please help!
The volume of a prism is calculated by multiplying the area of the base with the height of the prism. The correct answer is D. The area of the base times the height of the prism.
Explanation:The volume of a prism is calculated by multiplying the area of the base with the height of the prism. This means that out of the four options provided, the correct choice would be: D. The area of the base times the height of the prism.
For instance, if the area of the base of a rectangular prism is 30 square units and the height of that prism is 10 units, then the volume would be calculated as 30 (area of the base) * 10 (height of the prism) = 300 cubic units.

Kevin is 2 times as old as Gabriela. 12 years, Kevin was 6 times as old as Gabriela.How old is Gabriela now
Final answer:
Gabriela's current age is found by setting up algebraic equations based on the information that Kevin is twice as old as Gabriela now, and was six times as old 12 years ago. Solving the equations, we find that Gabriela is 15 years old.
Explanation:
Finding Gabriela's Current Age:
The problem statement tells us that Kevin is currently 2 times as old as Gabriela and that 12 years ago, Kevin was 6 times as old as Gabriela. To solve for Gabriela's current age, let us use algebra. Let's denote Gabriela's current age as G and Kevin's current age as K. The given information can be translated into the following two equations:
K = 2G (Kevin is 2 times as old as Gabriela now)K - 12 = 6(G - 12) (12 years ago, Kevin was 6 times as old as Gabriela)Substituting the first equation into the second, we get:
2G - 12 = 6(G - 12)
Expanding both sides:
2G - 12 = 6G - 72
Moving all terms involving G to one side and constant terms to the other side, we get:
2G - 6G = -72 + 12
-4G = -60
Dividing both sides by -4 to solve for G:
G = 15
So, Gabriela is currently 15 years old.

Alani uses 3/4 cup of pineapple juice to make one bread how much juice will she use to make 5 breads
To make five loaves of bread, Alani will use 3 3/4 cups of pineapple juice, calculated by multiplying the amount required for one loaf, which is 3/4 cup, by five.
To solve this, you multiply the amount of pineapple juice needed for one bread by the total number of breads.
Multiply the amount of juice for one bread by the number of breads: 3/4 cup × 5 = 15/4 cups.
Convert the improper fraction to a mixed number: 15/4 cups is equal to 3 3/4 cups.
Therefore, Alani will use 3 3/4 cups of pineapple juice to make five loaves of bread.

Express the given integral as the limit of a riemann sum but do not evaluate: the integral from 0 to 3 of the quantity x cubed minus 6 times x, dx.
To express the integral from 0 to 3 of the function as the limit of a Riemann sum, divide the interval into [tex]f(x) = x^3 - 6x[/tex] subintervals of equal width, find a Riemann sum, and then take the limit as n approaches infinity.
Explanation:To express the given integral as the limit of a Riemann sum without evaluating, we represent the integral of the function [tex]f(x) = x^3 - 6x[/tex]split the interval [0,3] into n equal subintervals, each of width Δx = 3/n. Then we choose sample points x_i in each subinterval [x_{i-1}, x_i]. The Riemann sum is thus [tex]R = Σ(x_i^3 - 6x_i)Δx[/tex]en from i=1 to n and x_i is any point in the ith subinterval.
As n approaches infinity, which is equivalent to Δx approaching zero, the Riemann sums converge to the integral. The limit of the Riemann sum is then represented as lim_{n to ∞} R, which gives the exact area under the curve f(x) between 0 and 3, but we are not evaluating this limit.
