Answer: C
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) = (3, - 0.5), thus
y = a(x - 3)² - 0.5
To find a substitute either of the x- intercepts into the equation.
Using (4, 0), then
0 = a(4 - 3)² - 0.5 = a - 0.5 ( add 0.5 to both sides )
a = 0.5
y = 0.5(x - 3)² - 0.5 ← equation of quadratic function

A recipe uses 5 cups of milk to make 25 servings. If the same amount of milk is used for each serving, how many servings can be made from three quarts?
The total number of servings is given by the equation A = 60 servings
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of servings from 3 quarts be A
Now , the equation will be
The number of servings for 5 cups of milk = 25 servings
So , the number of servings for 1 cup = 25 / 5
The number of servings for 1 cup of milk = 5 servings
And , 1 quart = 2 pints
1 pint = 2 cups
So , 1 quart = 4 cups
And , 3 quarts = 12 cups
So , The number of servings for 3 quarts or 12 cups of milk = 12 x number of servings for 1 cup of milk
Substituting the values in the equation , we get
The number of servings for 3 quarts or 12 cups of milk A = 12 x 5
The number of servings for 3 quarts or 12 cups of milk A = 60 servings
Therefore , the value of A is 60 servings
Hence , the number of servings is 60

Step-by-step explanation:
As YZ is parallel to VX, then ΔWYZ ≅ ΔWVX
⇒ WX : WV = WZ : ZX
⇒ 5.6 : (5.6 + 8.4) : 6.4 : (6.4 + J)
[tex]\implies \dfrac{5.6}{5.6+8.4}=\dfrac{6.4}{6.4+J}x^{2}[/tex]

Answer:
12520
Step-by-step explanation:
Firstly , we need to find 25²
25 × 25 = 625
Then let us multiply before we add on ,
20 × 25² = 20 × 625 = 12500
12500 + 20 = 12520
And this is the final answer.
Question
20 + 20 × 25²
Answer:
Step by step explanation:
=20 + 20 × 25²
=20 + 20 × (25 × 25)
=20 + 20 × 625
=20 + 12.500
=12.520

Two card are pulled from a normal deck of 52 cards, without replacement.
What are the odds of the two cards being a pair?
Answer:
The probability that both cards that are drawn are hearts is 1/17.
Step-by-Step-Explanation:
First off, know that there are 13 heart cards in the deck of 52 cards. Therefore, the chance of pulling a single heart card is 13/52. Let's say we do pull a heart card. Since there is no replacement for the heart card taken out of the deck, we now have 12 heart cards out of a deck of 51 cards. The chance of pulling out a heart card in now 12/51. To find the probability that both cards drawn out are hearts, multiply the two fractions together: (13/52)⋅(12/51)=156/2652=1/17.
So hence, your answer is 1/17-----------------------------------——————---------------------------------------------------------

Imagine the center of the Ferris wheel is located at (0, 0) on a coordinate grid, and the radius lies on the x-axis. Write an equation of a circle for your Ferris wheel, and sketch an image of what your Ferris wheel would look like on the grid. Now graph a circle that is similar to the Ferris Wheel. Discuss the transformations needed to show that both circles on your graph are similar.
The transformation needed to show that both circles on the graph are similar is dilation
How to model the equation of the Ferris wheelThe equation of a circle that has its center to be (0,0) is:
[tex]x^2 + y^2 = r^2[/tex]
Where r represents the radius of the circle.
The radius can take any positive value.
Assume r = 5, then the equation becomes
[tex]x^2 + y^2 = 5^2[/tex]
[tex]x^2 + y^2 = 25[/tex]
The above can represent the equation of the Ferris wheel
A circle similar to the Ferris wheel can have the following equation
[tex]x^2 + y^2 = 7^2[/tex]
[tex]x^2 + y^2 = 49[/tex]
The above circle equation has a radius of 7, and it passes through the center
So, we have:
[tex]r = 5[/tex] -- radius of the Ferris wheel
[tex]R = 7[/tex] -- radius of the similar circle
Since both circles pass through the center, either of the circles can be dilated to the other
