Write the equation of the quadratic function with roots -10 and -8 and a vertex at (-9, -3)
Answer:
y = 3x² + 54x + 240
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (- 9, - 3), thus
y = a(x + 9)² - 3
To find a substitute either of the roots into the equation
Using (- 8, 0), then
0 = a(- 8 + 9)² - 3
0 = a - 3 ( add 3 to both sides )
a = 3
y = 3(x + 9)² - 3 ← in vertex form
Expand factor and simplify
y = 3(x² + 18x + 81) - 3
= 3x² + 54x + 243 - 3
= 3x² + 54x + 240 ← in standard form
Which of the following statements uses the commutative property of addition?
2 + (3 + 4) = (2 + 3) + 4
2 + (3 + 4) = (2+ 3) + (2 + 4)
2 + (3 + 4) = 2 + (4 + 3)
The statement 2 + (3 + 4) = 2 + (4 + 3) is the one that uses the commutative property of addition, which states that changing the order of numbers being added does not affect the sum. So correct answer is first option.
The statement that uses the commutative property of addition is 2 + (3 + 4) = 2 + (4 + 3). The commutative property of addition states that the order in which two numbers are added does not change the sum.
This is represented by the equation A+B=B+A. In our specific example, changing the order of 3 and 4 does not affect the sum when added to 2.
This demonstrates the commutative property in a clear manner.
is 20 a perfect sqaure
Answer:
No. 16 is and 25 is.
Step-by-step explanation:
Final answer:
The number 20 is not a perfect square because there is no integer that when multiplied by itself equals 20.
Explanation:
The question "is 20 a perfect square" is related to Mathematics and involves understanding what constitutes a perfect square. A perfect square is a number that can be expressed as the product of an integer with itself. In other words, when you multiply an integer by itself, the resulting product is a perfect square. For example, the number 16 is a perfect square because it can be expressed as 4 times 4.
To determine if 20 is a perfect square, we look for an integer that when multiplied by itself equals 20. However, multiplying 4 by 4 gives us 16, and multiplying 5 by 5 gives us 25. Since there is no integer that can be multiplied by itself to give 20, we conclude that 20 is not a perfect square.

Determine the area of each face of a cube 306.6
Answer: 51.1 units squared
Step-by-step explanation: the area of each face is 306.6 so then you would divided that by 6 since there are 6 sides in a cube so you get 51.1 and if multiplied by 6 it equals 306.6
The area of each face of a cube 306.6 is 51.1 square units.
What is a cube?A solid three-dimensional shape called a cube contains six square faces, eight vertices, and twelve edges.
A cube has 6 faces.
So the area of each face is (side x side).
So total area is equal to 6 times the area of each side.
Area = 6 x (side x side)
Now, substitute in your numbers and solve for the side length
306.6 = 6 (side)²
so first divide both sides by 6,
we get,
(side)² = 51.1
Therefore, the area of each face is 51.1 square units.

what is the distributive property of 12 + 20
Answer:
12 + 20 = 4x3 + 4x5 = 4x(3 + 5)
Step-by-step explanation:
The distributive property states that
a*(b + c) = a*b + a*c
You can use the distributive property in reverse to factor out a common factor from the sum of 2 numbers. If you realize that 12 = 4*3 and 20 = 4*5 then you can write
12 + 20 = 4*3 + 4*5 = 4*(3 + 5)

Answer:

Step-by-step explanation:
We can express 5 × 23 as
5(20 + 3) ← distribute terms in parenthesis by 5
= 5 × 20 + 5 × 3
= 100 + 15
= 115
By distributive property , the number 5 x 23 = 115
What is Distributive Property?
The distributive property states that multiplying the sum of two or more addends by a number produces the same result as multiplying each addend individually by the number and adding the products together.
For a product of two numbers , a and d , d = b + c
By distributive property ,
a x ( b + c ) = a x b + a x c
Given data ,
Let the number be 5 x 23
Now , the number 23 can be split into ( 20 + 3 )
By opening the parentheses ,
5 x ( 20 + 3 )
The number 5 is first multiplied by 20 and then multiplied by 3 , and the sum of both the products will be taken
So ,
5 x 23 = 5 ( 20 + 3 )
5 x 23 = 5 ( 20 ) + 5 ( 3 )
5 x 23 = 100 + 15
5 x 23 = 115
Hence , by distributive property the product 5 x 23 is 115

40% of what number is 52?
A. 130
B. 200
C. 242
D. 1300
Answer:
130
Step-by-step explanation:
40 percent of what number is 52?
let this number be x
so, the equation is
40/100 x X= 52
divide 40/100 from both sides
X=52÷40/100
When you divide by a fraction, you multiply by its reciprocal
X=52 x 100/40
X=5200/40
X=130
40 percent of 130 is 52.
The value of the unknown number is 130.
Option A.
What is the value of the unknown number?Given the parameter:
"40% of what number is 52"
Let's represent the unknown number as "x."
To determine the number for which 40% is equal to 52, we can set up an equation and solve for the unknown number.
Hence:
40% of the number = 52
40% of x = 52
40% × x = 52
Convert the percentage to a decimal.
40% = 40/100 = 0.40
Now, rewrite the equation as:
0.40 × x = 52
0.4x = 52
To solve for the value of "x," divide both sides of the equation by 0.40:
x = 52/0.4
x = 130.
Therefore, 40 percent of 130 is 52.
Option A) 130 is the correct answer.

Your mother gave you $13.32 with which to buy a present. This covered 3/5 of the cost. How much did the present cost
Answer:
$22.20
Step-by-step explanation:
We are told that $13.32 only covered 3/5 of the cost. Does this mean it covered the whole cost? No. The 5 in the denominator represents the whole cost, and the 3 represents the fraction of the cost. In this case, 13.32 represents the 3, as it did not cover the whole cost.
Let's set up our equation by making 13.32 into a fraction.
13.32/x
We will represent the present's actual cost with the letter x.
13.32/x = 3/5
We want to make sure the 13.32 is in the numerator, equal to the 3 in the numerator in the 3/5 number, because we know that $13.32 only covered for a fraction of the present's cost, not the whole cost.
We solve this by doing cross multiplication. Multiply the 13.32 by the 5.
13.32 x 5 = 66.6
Next we divide 66.6 by 3 to get 22.2
66.6/3 = 22.2
This gives us our final answer of $22.20. This means that the cost of the original present was $22.20
The question involves setting up a proportion to find the total cost of the present. This was done step-by-step by dividing $13.32 by 3 to find 1/5 of the cost, and then multiplying by 5 to find the full cost. The present cost approximately $22.20
Explanation:The subject of your question is mathematics, particularly a topic in proportion. The information given is that $13.32 represents 3/5 of the cost of the present. We could set up a proportion to help calculate the full cost. If 3/5 is equal to $13.32, then 1 (or 5/5) would be equal to the full price of the present. We can solve for the full price by dividing $13.32 by 3 and then multiplying by 5 (since 5/5 represents the whole or full cost).
Step-by-step:
Divide $13.32 by 3. This gives you approximately $4.44, which represents the cost for 1/5 of the present. Multiply $4.44 by 5. This will give you the full cost of the present which is approximately $22.20.Learn more about Proportion here:https://brainly.com/question/31548894

Solve the system of equations
6x+7y = 5 2x-3y =7
Answer:
The solution is (2 , -1)
Step-by-step explanation:
* You have two ways to solve the system of equations
1. Elimination method:
By making the coefficients of one of the two variables equal in the 2
equations in magnitude and different in sign to eliminate it and find the
other variable
2. Substitution method:
By finding one of the two variables in terms of the other in one of the
two equations and substitute this value in the second equation
* Lets solve our system using the elimination method
∵ 6x + 7y = 5 ⇒ (1)
∵ 2x - 3y = 7 ⇒ (2)
- Multiply equation (2) by -3 to eliminate x
∵ (-3)(2x) - (-3)(3y) = (-3)(7)
∴ -6x + 9y = -21 ⇒ (3)
- Add equation (1) and (3)
∴ 7y + 9y = 5 + -21
∴ 16y = -16
- Divide each side by 16
∴ y = -1
- Substitute the value of y in equation (1)
∴ 6x + 7(-1) = 5
∴ 6x - 7 = 5
- Add 7 to both sides
∴ 6x = 12
- Divide both sides by 6
∴ x = 2
* The solution is (2 , -1)

B.9x − 3
C.12x + 5
D.12x − 3
Answer:
The answer is D. 12x - 3.
Step-by-step explanation:
To add these functions, we just add the terms.
f(x) + g(x) = (7x - 4) + (5x + 1)
7x - 4 + 5x + 1 | Simplify
7x + 5x - 3
12x - 3.
Answer:
Option D. (12x - 3)
Step-by-step explanation:
Madden's total cups of coffee made is represented by the function f(x).
f(x) = 7x - 4
Jenn's total cups of coffee made is represented by the function g(x).
g(x) = 5x + 1
Now we have to write a function that represents the total cup of coffee that represents they made.
That will be represented by f(x) + g(x) = (7x - 4) + (5x + 1)
f(x) + g(x) = 12x - 3
Therefore, option D. will be the answer.
