(Simplify your answer.)

Answers

Answer:

[tex]f(3) = -16[/tex]

Step-by-step explanation:

Given

[tex]f(x)= - 4x-4[/tex]

[tex]g(x)= 4x^2 + 4x + 2[/tex]

[tex]h(x)= 3x^2 - 3[/tex]

Required

[tex]f(3)[/tex]

We have:

[tex]f(x)= - 4x-4[/tex]

Substitute [tex]x = 3[/tex]

[tex]f(3) = -4 * 3 - 4[/tex]

[tex]f(3) = -12 - 4[/tex]

[tex]f(3) = -16[/tex]

Hence:

[tex]f(3) = -16[/tex]

c. cardioid
d. lemniscate

Answers

Answer:

Limaçon

Step-by-step explanation:

In geometry, a limaçon or limacon /ˈlɪməsɒn/, also known as a limaçon of Pascal, is defined as a roulette formed by the path of a point fixed to a circle when that circle rolls around the outside of a circle of equal radius.

The name of the shape depicted in the graph below is a. Limacon.

What are Polar Curves?

Polar curves are the curves which are formed using the polar coordinate system.

The distance of the points from the origin will be varying depending on the angle from the positive X axis.

The given curves in the option Limacon, Rose, Cardioid, Lemniscate are types of polar curves.

Limacon is the curve which is also known as Pascal's snail. It is formed by following the path by a fixed point to a circle when this circle rolls another circle's of equal radius outside.

The given shape is the limacon with inner loop.

Lemniscate will always be a 8 shaped curve.

Hence the correct option is a, limacon.

Answer:

A) 26°

Step-by-step explanation:

The angle x decreases at a rate that is 12 times the rate of increase of angle y.

x = 360 -12y

We want x = 2y, so ...

2y = 360 -12y

14y = 360

y = 360/14 ≈ 25.71 ≈ 26

The integer angle closest to y is 26°.

Cost to store-$152, Mark up 50%, Selling Price-?

Answers

Answer:

Amount of selling cost = $228

Step-by-step explanation:

Given:

Amount of cost to store = $152

Mark up = 50%

Find:

Amount of selling cost

Computation:

Amount of mark up = Amount of cost to store x Mark up

Amount of mark up = 152 x 50%

Amount of mark up = $76

Amount of selling cost = Amount of cost to store + Amount of mark up

Amount of selling cost = 152 + 76

Amount of selling cost = $228

A 4-column table with 5 rows. The first column is labeled age (years) with entries 1, 2, 3, 4, 5. The second column is labeled given value with entries 15, 12, 9, 5, 4. The third column is labeled predicted with entries 14.8, 11.9, 9, 6.1, 3.2. The fourth column is labeled residual with entries 0.2, 0.1, 0, negative 1.1, 0.8. Which point would be on a residual plot of the data?

Answers

Answer:

3,0

Step-by-step explanation:

From the table we can say that the point which is residual plot of the data is (3,0).

What is residual plot?

Residual plot shows the difference between observed and fitted values of the data. It is also known as null residual plot. In this random values in data is taken.

How to find point?

We have been given the following table:

Age Value Predicted Residual

1 15 14.8 0.2

2 12 11.9 0.1

3 9 9 0

4 5 6.1 1.1

5 4 3.2 0.8

If we observe the table then we can find that the third row of fourth column contains 0 so the point which is residual plot of the data is (3,0).

Hence the point which contains the residual plot of the data is (3,0).

Answer:

3.13π

Step-by-step explanation:

One plane is a quarter of a semi-circle, since the semi-circle is split into four equal parts. One quarter of a semicircle is one eighth of a circle, so find the are of a circle with diameter 10ft, and divide by 8:

Diameter is half the radius, so the radius is 5ft.

Area of a circle = π(radius)²

=5²π

Answer:

The shop

Step-by-step explanation:

Given

Shop

[tex]Cost = E9[/tex]

[tex]Bag = 12.5kg[/tex]

Supermarket

[tex]Cost=E1.83[/tex]

[tex]Bag = 2.5kg[/tex]

Required

The better value

To do this, we simply calculate the unit price.

This is calculated as:

[tex]Unit = \frac{Price}{Bag}[/tex]

So, we have:

Shop

[tex]Unit = \frac{9}{12.5}[/tex]

[tex]Unit = 0.72[/tex]

Supermarket

[tex]Unit = \frac{1.83}{2.5}[/tex]

[tex]Unit = 0.732[/tex]

At the shop, the unit price is £0.72 per bag while at the supermarket, the unit price is £0.732

The best value is at the shop, because it is cheaper

i.e.

[tex]0.72 < 0.732[/tex]

3(x-5) = 2(x-5)+x true or false?

Answers

Answer:

FALSE

Step-by-step explanation:

In order to solve this equation,

First, we must write it out

3(x - 5) = 2(x - 5) + x

Then, we must use the Distributive Property

3x - 15 = 2x - 10 + x

Next, we must Combine Like Terms

3x - 15 = 3x - 10

Finally, we can Subtract The Coefficients

-15 = -10

Because -15 does not equal to -10, this equation has no solution

IT IS FALSE

Irene is making bags of trail mix for hiking club. She will use 22 ounces of walnuts, 11.2 ounces of
almonds, and 12.3 ounces of cashews. This amount makes 25 bags of trail mix. How many
ounces are in each bag?

Please help :/ if i dont finish theses questions i will go to summer school & i dont wanna go there

Answers

Answer:

In each bag there will be 1.82 ounces of mixture.

Step-by-step explanation:

Since Irene is making bags of trail mix for hiking club, and she will use 22 ounces of walnuts, 11.2 ounces of almonds, and 12.3 ounces of cashews to make 25 bags of trail mix, to determine how many ounces are in each bag you must perform the following calculation:

(22 + 11.2 + 12.3) / 25 = X

45.5 / 25 = X

1.82 = X

Thus, in each bag there will be 1.82 ounces of mixture.
