Find the coordinates of the vertex for the parabola defined by the given quadratic function.
f(x) = 2x² – 20x +7
The vertex is
(Type an ordered pair.)
Answer:
(5, -43)
Step-by-step explanation:
The value of the x-coordinate of the vertex of a function in standard form is given by -b/2a. The value of a is the coefficient of the x^2 term. The value of b is the coefficient of the x term. In this problem, a = 2 and b = -20. When you evaluate -b/2a you would replace the b with -20 and replace the a with 2 so you get -(-20)/2(2) so the value of x is 5. Determine the value of y by evaluating f(5) = 2(5)^2 - 20(5) +7.
Use the order of operations to simplify the expression.
(5)^2 - (1/4)^2

Answer:
The first answer choice is correct due to its Y-Intercept
Step-by-step explanation:
Of your 2 answer choices, the first answer choice is the best.
This is because your Y-Intercept is one of the most important things you look our first.
It should be (0,-4) which the first one clearly has.
Now, you could look at the growth, it is growing at a different rate that is increasing as opposed to a constant rate.
Both of them have that, but like I said the Y-Intercept Clearly exposed the right answer.
Therefore The first answer choice is correct.

So, to find the mean they added up the scores from 20 seasons and divided by 20, the number of seasons to get an average score of 10.4.
10.4 = (x1 +x2 +x3 ... +x20 )/20
Then;
10.4*(20) = (x1 +x2 +x3 ... +x20 )
208 = sum of the first 20 seasons
We want to add one more number in there, the 21st season with a score of 14. Add the 14 to the sum of the first 20 seasons and then divide by 21, the new number of seasons you're averaging.

Answer:
41/25
Step-by-step explanation:
So (-1)¹⁰ equals 1 because any number multiplied by a positive exponent is positive. Next, you do (-22)⁰ which equals 1. Anything to the zeroth power equals one. Now you add 1 and 1 which equals 2. Then you do -(3/5)² which equals -9/25 (You do 3 * 3 which equals 9 and 5 * 5 which equals 25. You then add the negative sign outside the parenthesis to get -9/25). Then you multiply 2 by 25 so both numbers have a common denominator of 25. That equals 50/25 ( 50/25 is 2). You subtract 50/25 by 9/25. That equals 41/25.

Hamilton, NY has 73465 residents, and 12 members on their Board of Trustees. The three districts of Basel, Heights, and Dagonal have the following populations:
Basel: 13,244 Heights: 30, 415 Dagonal: 29,806
Determine the standard quota (to two decimal places) for the Dagonal district.
6) Gotham City is to apportion 16 seats to districts with populations as follows:
North: 785 South: 1,125 East: 1,950 West: 415
Find the standard divisor
What are the standard, lower, and upper quotas for the four districts?
a) The determination of the standard quota for the Dagonal district is 40.57%.
b) 1. The standard divisor is 267.19 (4,275/16).
2. The standard, lower, and upper quotas for the four districts are as follow:
North South East West
Standard quota 18.36% 26.32% 45.61% 9.71%
Lower quota 18% 26% 45% 9%
Upper quota 18% 26% 46% 10%
What is the quota method of apportionment?The quota method of apportionment is the use of the standard divisor to round off standard quotas, according to some agreed ground norms.
When the standard quota is rounded down to an integer, it gives the lower quota, and rounding up gives the upper quota.
The standard divisor is calculated as the total population divided by the total number of seats.
The standard divisor gives the average number of people represented by a Board or seat member.

The function f(x) = x2 is translated 7 units to the left and 3 units down to form the function g(x). Which represents g(x)?
A. g(x) = (x − 7)2 − 3
B. g(x) = (x + 7)2 − 3
C. g(x) = (x − 3)2 − 7
D. g(x) = (x − 3)2 + 7
Answer:
B. g(x)=(x+7)^2-3
Step-by-step explanation:
Vertex form is F(x)= a(x-h)^2+k
a is the reflection
h and k are the vertex (x,y) = (h,k)
in this case there is no shrink or stretch (a)
if it is translating left or right it is "h". In this case it is translated left so its -7. However if you look at vertex form it is "x-h" so -7-7= +7
If it translating up or down it is "K". In this case it is translated down so its -3.
If it was translated up or right then its positive. If it was translated down or left its negative.
After you figure out what h and k are then you just plug it in. h=-7, k=-3
so the answer in vertex form is, g(x)=(x+7)^2-3

Explain how you would add 38+45
Answer:
83
Step-by-step explanation:
first add whatever is in the 1's place so for 38, 8 is in the 1's place and for 45, 5 is in the 1's place
so first it will be 8+5 which is 13 so you are going to carry the 1 over to the tens place so now it will be 30 + 40 + 10 and that equals 80 so you add 80 and 3 which looks like 80+3 and that equals 83

In shop class, Adriana makes a pyramid with a 4-inch square base and a height of 6 inches. She then cuts the pyramid vertically in half as shown. What is the area of each cut surface?
The area of the square pyramid is the amount of space on it
The total surface area of each cut surface is 33.28 square inches
How to determine the surface area of each cut surface?The given parameters are:
Base (b) = 4 cm
Height (h) = 6 cm
Start by calculating the slant height (l) using:
l = √((4/2)^2 + 6^2)
l = 6.32
The lateral surface area is calculated using:
L = 2bl
So, we have:
L = 2 * 4 * 6.32
Evaluate the product
L = 50.56
The total surface area is calculated using:
T = L + b^2
So, we have:
T = 50.56 + 4^2
Evaluate
T = 66.56
Divide the total surface area by 2
T/2 = 33.28
Hence, the total surface area of each cut surface is 33.28 square inches

Step-by-step explanation:
this question has been asked before and answered incorrectly but people corrected them in the comments.
A circular sinkhole has opened near an intersection. The four corners of the intersection are occupied by a grocery store, a dollar store, a gas station, and a restaurant, and each corner contains part of the sink hole. The grocery stores property has 2/3 of the angle in the intersection at the dollar store has, but has 5° more of the sinkhole edge to stabilize. The gas station has the same angle on the intersection at the dollar store and 88° more edge To stabilize. What is the measure of the arc of the sinkhole that falls within the restaurants property?
The measure of the arc of the sinkhole that falls within the restaurants property is -21°
Measure of angles subtendedLet x be the angle at the dollar store at the intersection
Now the angle of the grocery store at the intersection, y is 2/3 that of the dollar store. So, y = 2x/3
Since both x and y are supplementary,
x + y = 180°
x + 2x/3 = 180°
5x/3 = 180°
x = 180° × 3/5
x = 36° × 3
x = 108°
Angle subtended by gas station at sinkholeThe gas station has the same angle at the intersection but has 88° more of the sinkhole edge to stabilize. So, the angle the gas station store subtends at the sinkhole is z = x + 88°
Angle subtended by grocery store at sinkholeAlso, since the grocery stores property has 2/3 of the angle in the intersection at the dollar store has, but has 5° more of the sinkhole edge to stabilize. The angle the grocery store subtends at the sinkhole is k = y + 5° = 2x/3 + 5°
Measure of arc subtented by restuarantLet k' be the angle subtended by the restuarant at the sinkhole.
Since the sinkhole is a circle, we have that
x + z + k + k' = 360°
x + x + 88° + 2x/3 + 5° + k' = 360°
8x/3 + 93° + k' = 360°
8x/3 + k' = 360° - 93°
8x/3 + k' = 267°
So, making k' subject of the formula, we have
k' = 267° - 8x/3
Substituting the values of the variables into the equation, we have
k' = 267° - 8 × 108°/3
k' = 267° - 288°
k' = -21°
So, the measure of the arc of the sinkhole that falls within the restaurants property is -21°
