to the amount of food that my cat Poe eats is 3 : 2.
If Jade eats 6 ounces of food, how many ounces of
food will Poe eat? (Your answer should be a whole
number.)
Answer: 4
Step-by-step explanation:
6/? = 3/2
3 x 2 = 6
2 x 2 = 4
Therefore; 4
The ounces of food that Poe eat is 4 ounces.
What is Ratio?Ratio is defined as the relationship between two quantities where it tells how much one quantity is contained in the other.
The ratio of a and b is denoted as a : b.
Given that,
ratio of the amount of food that my cat Jade eats to the amount of food that my cat Poe eats is 3 : 2.
For some constant k,
Ounces of food Jade eat = 3k
Ounces of food Poe eat = 2k
Jade eats 6 ounces of food.
3k = 6
k = 6 / 3 = 2
Ounces of food that Poe eats = 2k = 2 × 2 = 4
Hence Poe eats 4 ounces of food if Jade eats 6 ounces of food.

The standard form for a parabola with vertex (h,k) and an axis of symmetry of y=k is:(y-k)^2=4p(x-h)The description below is for a parabola. Write it in standard form. When answering the questions type coordinates with parentheses and separated by a comma like this (x,y). If a value is a non-integer then type is a decimal rounded to the nearest hundredth.Vertex is (2,2); directrix is x=2-\sqrt[]{2}, focus is (2+\sqrt[]{2},2)The value for p is: AnswerThe value for h is: AnswerThe value for k is: Answer
Given that a parabola has
[tex]\begin{gathered} Vertexis(2,2) \\ directrix\text{ }is\text{ }x=2-\sqrt[]{2} \\ focus\text{ }is\text{ }(2+\sqrt[]{2},2) \end{gathered}[/tex]And that the standard form of a parabola can be expressed as
[tex]\mleft(y-k\mright)^2=4p\mleft(x-h\mright)[/tex]We are asked to find the value of p, h and k. This can be seen below.
Explanation
Recall, If a parabola has a horizontal axis, the standard form of the equation of the parabola is this
[tex](y-k)^2=4p(x-h)[/tex]where p≠ 0. The vertex of this parabola is at (h, k). The focus is at (h + p, k). The directrix is the line x = h - p. The axis is the line y = k. If p > 0, the parabola opens to the right, and if p < 0, the parabola opens to the left.
Value of h and k

Hello there. To solve this question, we'll have to remember some properties about dividing polynomials.
Given the polynomials, we want to evaluate the division:
[tex](1+3x+x^4)\div(3-2x+x^2)[/tex]Rewriting it the way we perform long division:
We start with the higher degree terms, namely x^4 and x².
Dividing x^4 by x², we get x². Now we multiply every term from the division by this factor and subtract from the term being divided.
Now, we have a 2x³ as the higher degree term from the term being divided. Dividing it by x², we get 2x. Multiply each term of the divisor and subtract from it.
Finally, the highest degree term from the term being divided is x². Dividing it by x², we get 1. Multiply each term of the divisor and subtract it from the dividend.
Now, the highest degree term from the dividend is -x, when the highest degree term from the divisor is x². We cannot proceed with the long division anymore.
It means that we have a quotient:
[tex]x^2+2x+1[/tex]And a remainder:
[tex]-x-2[/tex]Notice if we rewrite it as:
[tex]x^4+3x^2+1=(x^2-2x+3)\cdot(x^2+2x+1)-x-2[/tex]We have the division P(x)/D(x) written in the form:
[tex]P(x)=D(x)\cdot Q(x)+R(x)[/tex]Where Q(x) and R(x) are the quotient and remainder polynomials.

x=4b) 150 g of syrup are needed to make 8 flapjacks.
Find the quantity of oats needed to make 16 of these flapjacks.
Based on the fact that 150g of syrup are needed when making 8 flapjacks, the quantity that is needed to make 16 flapjacks is 300 g.
How to find out quantity needed?The quantity of oats needed to make 8 flapjacks is 150 g.
Assuming direct proportion, the quantity of oats needed to make 16 flapjacks can be found by the formula:
= (Quantity of oats needed for 8 flapjacks x Number of flapjacks to be made) / Number of flapjacks made
Solving for the quantity of oats needed gives:
= (150 x 16) / 8

If a triangle’s original dimensions are 24 cm by 40 cm, which triangle would be an enlargement of the original by a scale factor of 2.2?
The triangle’s enlargement dimensions will be 52.8 cm by 80 cm.
What is scale factor?The size by which the shape is enlarged or reduced is called as its scale factor.
Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape.
It is used to increase or decrease the size of an object.
The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.
For example, a rectangle has a length of 5 units and a width of 2 units. Now, if we increase the size of this rectangle by a scale factor of 2, the sides will become 10 units and 4 units, respectively. Hence, we can use the scale factor to get the dimensions of the changed figures.
Given:
A triangle’s original dimensions are 24 cm by 40 cm
scale factor=2.2
Thus,
enlarged dimensions= scale factor x original dimensions
[2.2] x 24 = 52.8 cm
[2.2] x 40 = 80 cm
Hence, the triangle’s enlargement dimensions will be 52.8 cm by 80 cm.

What steps would you need to take to graph the function:
f(x)=-3x^3-6x^2+3x+6
Name any x-intercepts and y-intercepts in the graph of the function.
Describe the end behavior of the function.
For extra credit, draw a sketch of the function by hand or in Paint.
The x-intercepts in the graph are ( - 2, 0 ), ( 1, 0 ) and ( - 1, 0 ) and the y-intercepts of the graph is ( 0, 6). The graph of the function tends to infinity in the negative y-axis direction after intersecting the x-axis at ( 1, 0).
Consider the function,
f(x) = - 3x³ - 6x² + 3x + 6
To find the x-intercept of the function we substitute y = 0.
f(x) = y = - 3x³ - 6x² + 3x + 6
- 3x³ - 6x² + 3x + 6 = 0
3x³ + 6x² - 3x - 6 = 0
3x²( x + 2 ) - 3 ( x - 2) = 0
( x + 2 )( 3x² - 3) = 0
Therefore,
x = - 2 and;
3x² - 3 = 0
3x² = 3
x = ± 1
Hence, the x-intercepts are ( - 2, 0 ), ( 1, 0 ) and ( - 1, 0 ).
Now, the y-intercept will be when x = 0,
y = - 3x³ - 6x² + 3x + 6
y = - 3(0)³ - 6(0)² + 3(0) + 6
y = 6
Hence, the y-intercept is ( 0, 6).
The graph of the function intersects the x-axis at ( - 2, 0) and ( - 1, 0 ) and then intersects the y-axis at ( 0, 6) then after intersecting the x-axis at ( 1, 0 ) the graph tends to infinity in the negative x-axis direction.

the equation of a line is y=mx+b. if we know the line passes through (7,8), what does that tell us
The equation of the line is given as y = -2x + 22. This means that when x is equal to zero, y = 22. M also shows how steep the line is, being the gradient.
What is the calculation that justified the above?In order to arrive at a logical solution, we must assume the value of the slope as this is not given.
Assuming the slope of the line is -2, we thus can say:
The equation of a line that passes through a point (x₁,y₁) and a slope m is given by
(y - y1) = m (x - x1)
Recall that the slope, m = -2
While
Point (x1, y1) = (7, 8)
Hence, the equation of the line is:
y-8 = (-2) (x-7)
y-8 = -2x + 14
y = -2x+ 14 + 8
Hence,
y = -2x + 22

Each line in the Euclidean plane that is defined by a solution to a linear equation can be thought of as the sum of all solutions to a linear model with two variables.This is how equations in this class came to be referred to be "linear." A hyperplane of size n in Euclidean space is made up of all the solutions to an equation system with integer variables (a subdomain of dimension n1).The usage of linear equations is widespread throughout all fields of mathematics, physics, and engineering because they can commonly properly represent non-linear systems.The graph of the line passes through (0,9) and (2,6) .

9 hearing aids are produced and sold.
The revenue, R(x), of producing and selling 'x' Awesome Hearing Aids is modeled by the function,
R(x) = -3x² + 56x
We need to find the number of hearing aids produced and sold in order to maximize the revenue.
We use the differentiation method to find the maximum of the function R(x).
Differentiate R(x) with respect to x and equate it with 0,
R'(x) = -6x + 56
Then, -6x + 56 = 0
⇒ 6x = 56
⇒ x = 56/6 = 9.33 ≈ 9 [since x is the number of hearing aids]
Now we find the second derivative of R(x) at x = 9.
R''(x) = -6
⇒ R''(9) = -6 < 0
Since R''(9) < 0, the revenue R(x) is maximum at x = 9.
So the maximum revenue is obtained after x = 9.
Therefore maximum revenue = R(9) = -3 x 9²+56 x 9 = $ 261
