The standard form of the vertex form equation is y = 2x² - 12x + 17
How to convert the equation?The vertex form of a quadratic equation is represented as:
y = a(x - h)² + k
Using the above form, the quadratic equation can be represented as:
y = 2(x - 3)² + 1
Expand
y = 2(x² - 6x + 9) - 1
Further expand
y = 2x² - 12x + 18 - 1
Evaluate the like terms
y = 2x² - 12x + 17
Hence, the standard form of the vertex form equation is y = 2x² - 12x + 17

You decide to buy a car with a base price of $11,499 at an interest rate of 6.2%. The car will be compounded monthly in those 5 years. What will your monthly payment be? Round the money to the nearest hundredth
Answer:
A = $15,696.72
Step-by-step explanation:
Use the compound amount formula: A = P(1 + r/n)^(nt). Here the number of compounding periods is nt, or (12 per year)(5 years) = 60.
Our formula becomes A = $11,499(1 + 0.062/12)^60, which works out to:
A = $11,499(1 + 0.0052)^60, or
A = $15,696.72
The monthly payment is $15,696.72/60, or $261.61.
Which of the following statements are true about the graph of f(x) = 6(x + 1)2 -9?
Check all of the boxes that apply.
a. The vertex is (1, -9).
b. The graph opens upward.
c. The graph is obtained by shifting the graph of f(x) = 6(x + 1)2 up 9 units.
d. The graph is steeper than the graph of f(x) = x2.
e. The graph is the same as the graph of f(x) = 6x2 + 12x - 3.
Answer:
Step-by-step explanation:
a. The vertex is (1, -9). False. The vertex is (-1, -9).
b. The graph opens upward. True. That coefficient '6' is positive.
c. The graph is obtained by shifting the graph of f(x) = 6(x + 1)2 up 9 units. False. It's DOWN 9 units.
d. The graph is steeper than the graph of f(x) = x^2. True. The given function increases 6 times faster than does x^2.
e. The graph is the same as the graph of f(x) = 6x2 + 12x - 3.
Let's put f(x) = 6(x + 1)^2 -9 into standard form. Expanding the first term, we get f(x) = 6(x^2 + 2x + 1) - 9, or f(x) = 6x^2 + 12x + 6 - 9. YES, TRUE

The sum of two numbers is 17

Find the two numbers
Graph the equations, and determine your answer by marking the point of intersection
The two numbers are 7 and 10 whose sum is 17 and whose difference is 3.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that the sum of two numbers is 17 and the difference of those same two numbers is 3.
We need to find those two numbers.
Let x and y are the two numbers.
Sum of two numbers is 17
x+y=17..(1)
Difference of two numbers is 3
x-y=3..(2)
From equation 1,
x=17-y
Now substitute this in equation 2.
17-y-y=3
17-2y=3
17-3=2y
14=2y
Divide both sides by 2
y=7
Now add y value in equation 1
x+7=17
Subtract 7 from both sides
x=10
Hence, the two numbers are 7 and 10.

What is the equation of a circle that has a diameter of 10 units if its center is at (3,8)?
Answer:
Step-by-step explanation:
[tex](x-3)^2+(y-8)^2 = 25[/tex]
The equation of circle: (x - 3)² + (y - 8)² = 25
What is equation of circle?An equation of circle with center (h, k) and radius 'r' is,
(x - h)² + (y - k)² = r²
For given example,
a diameter of circle = 10 units
So, the radius would be (r) = 10/2
r = 5 units
And the center (h, k) = (3, 8)
So, the equation of the circle would be,
⇒ (x - 3)² + (y - 8)² = 5²
⇒ (x - 3)² + (y - 8)² = 25
Therefore, the equation of circle: (x - 3)² + (y - 8)² = 25

Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as there are no options to select from.
However, a general explanation is as follows.
Given
[tex]2\ cups = 1\ pint[/tex]
Required
Is [tex]c = 2p[/tex] a correct expression?
Let
[tex]c = cups[/tex]
[tex]p = pint[/tex]
So:
[tex]2\ cups = 1\ pint[/tex]
becomes
[tex]2 * c = 1 * p[/tex]
[tex]2c = p[/tex]
Divide both sides by 2
[tex]c =\frac{1}{2}p[/tex]
Hence:
[tex]c = 2p[/tex] is incorrect

When the winning score in golf is the lowest number, the lowest number is -1.
The value of the expression -273 - (-576) will be:
= -273 - (-576)
= -273 + 576
= 303
Also, -56/4 = -14. The value of the expression (2 - 19) + (-12) will be:
= (2 - 19) + (-12)
= -17 - 12
= -29
The value of -2x = 22 will be:
-2x = 22
Divide both side by -2
-2x/-2 = 22/-2
x = -11
The value of 5 + 3x = -22 will be;
5 + 3x = -22
5x = - 22 - 5
3x = -27
x = -27/3 = -9
5(x + 3) = 35
5x + 15 = 35
5x = 35 - 15

What fraction of all the 10-digit numbers with distinct digits have the property that the sum of every pair of neighboring digits is odd?
Answer:
1/126
Step-by-step explanation:
Answer attached, I hope this is the answer.
the sum of every pair of neighboring digits is odd must be odd number and even number in the neighbor. (different parity)
The fraction of all the 10-digit numbers with distinct digits that have the property that the sum of every pair of neighboring digits is odd is 1/126.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
We have two types of fractions.
Proper fraction and improper fraction.
A proper fraction is a fraction whose numerator is less than the denominator.
An improper fraction is a fraction where the numerator is greater than the denominator.
Example:
1/2, 1/3 is a fraction.
3/6, 99/999 is a fraction.
1/4 is a fraction.
We have,
For a 10-digit number to have the property that the sum of every pair of neighboring digits is odd, the digits must alternate between odd and even numbers.
Specifically, if the first digit is odd, then the second digit must be even, the third digit must be odd, the fourth digit must be even, and so on.
If the first digit is even, then the second digit must be odd, the third digit must be even, the fourth digit must be odd, and so on.
There are 5 odd digits and 5 even digits, so there are 5 choices for the first digit. After selecting the first digit, there are 5 choices for the second digit (it must be one of the other type), 4 choices for the third digit (it must be the opposite type of the second digit), 4 choices for the fourth digit (it must be the opposite type of the third digit), and so on.
Therefore, the number of 10-digit numbers with distinct digits that have the given property is:
5 x 5 x 4 x 4 x 3 x 3 x 2 x 2 x 1 x 1 = 5! x 4!
where the factorials arise from the number of choices for each digit.
The total number of 10-digit numbers with distinct digits is:
10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 10!
Therefore, the fraction of all the 10-digit numbers with distinct digits that have the given property is:
(5! x 4!) / 10! = (5! x 4!) / (10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) = 1/126
Thus,
The fraction of all the 10-digit numbers with distinct digits that have the property that the sum of every pair of neighboring digits is odd is 1/126.
