A would be wrong because the second part (up 1) would give you (5,1) The origin is (0,0)

B is correct because (5,0) has a 5 as the x coordinate

C is wrong because the y coordinate is 0

D is wrong because A is on the x since the y coordinate is 0

E is correct because (5,0) has a 5 on the x and a 0 on the y

Step-by-step explanation:

use the F.O.I.L method to solve this.

"firsts"

1 * 2 = 2

"outsides"

1 * -√3 = -√3

"insides"

√3 * 2 = 2√3

"lasts"

√3 * - √3 = -3

so you get:

2 - √3 + 2√3 - 3

phone, it can expect to sell 1,000-2x phones.
The company uses the function r defined by r(x)=x⋅(1,000−2x) to model the expected revenue, in dollars, from selling cell phones at x dollars each.

Answer the 2 questions below.



a) What are the X-Intercepts and what do they mean in this situation?

b) At what price should the company sell their phones to get the maximum revenue? Explain your reasoning

Answers

Answer:

Step-by-step explanation:

The x intercepts are 0 and

1000 - 2x = 0              given condition

1000 = 2x                   Divide by 2

500 = x

So the two intercepts are 0,0 and 500,0

The intercepts mean that for (0,0) the phone company hasn't charged anything, yet. For 500,0 the phone company can sell a single phone -- not when they cost 500 dollars apiece.

The answer to the B part is completing the square.

r(x) = - 2x^2 + 1000x

r(x) = -2(x^2 - 500x )

1/2 ( 500) = 250

250^2 is what you put inside the bracket's to complete the square.

r(x) =  - 2(x^2 - 500x + 250^2) + 2*250^2

r(x) = -2(x - 250)^2 + 2*62500

r(x) = - 2(x - 250)^2 + 125000

They should sell their phones at 250 dollars a piece. The total revenue is 125000. Your graph shows exactly the same thing.

Answer:

Properties of Dilation

Each angle of the figure is the same. Midpoints of the sides of the figure remain the same as the midpoint of the dilated shape. Parallel and perpendicular lines in the figure remain the same as the parallel and perpendicular lines of the dilated figure. The images remain the same.

Similarity. In order for two figures to be similar, they must have congruent (equal) corresponding angle measures and proportional sides. Dilations create similar figures because multiplying by the scale factor creates proportional sides while leaving the angle measure and the shape the same.

A similarity transformation is one or more rigid transformations (reflection, rotation, translation) followed by a dilation. When a figure is transformed by a similarity transformation, an image is created that is similar to the original figure. ... In general, similarity transformations preserve angles.

A dilation stretches or shrinks a figure. The image created by a dilation is similar to the original figure. The scale factor of a dilation is the ratio of corresponding side lengths. In this course, the center of dilation will always be the origin.

Dilations in Animation

The three basic rigid motions are translations, reflections, and rotations. In addition to being rigid motions, these are also considered transformations. Transformations change the location or orientation of an image but not the shape.

Isometric transformations have the same shape AND size, similarity transformations just have the same shape. Isometric transformations have the same shape AND size, similarity transformations just have the same size. They are the same, no differences. ... A stretch is not a similarity transformation.

Felipe’s solution to an equation is shown below:


Given: x^2+6x+8=0

Step 1: (x+2)(x+4)=0

Step 2: x+2=0 or x+4=0

Step 3: x= -2 or x= -4


Which property of real numbers did Felipe’s use for step 2?


A. Distributive property of multiplication over addition


B: Multiplication property of equality


C. Commutative property of multiplication


D: Zero product of multiplication

Answers

Answer:

D. Zero product of multiplication

Step-by-step explanation:

The given equation is presented as follows;

Given: x² + 6·x + 8 = 0

By factorization, to find numbers represented by variables, 'a' and 'b', such that  a + b = 6 and a×b = 8, we have, a = 2, and b = 8 as a possible solution by observation

Step 1: (x + 2)·(x + 4) = 0

Given that (x + 2) × (x + 4) = 0, we have

Step 2: x + 2 = 0 or x + 4 = 0, by zero product of multiplication

The zero-product property states that the when two non zero numbers are multiplied, the result is nonzero

Therefore, when two numbers are multiplied, and have a result of zero, for example, i × j = 0, then, either, i = 0, or j = 0

By the zero-product rule, either, (x + 2) = 0, or (x + 4) = 0

Therefore, we have;

Therefore;

Step 3: x = -2 or x = -4

The property of real numbers Felipe's use for step 2 is the Zero product of multiplication.

Find the volume of a pyramid with a square base, where the side length of the
base is 8.7 cm and the height of the pyramid is 13.1 cm. Round your answer
to the nearest tenth of a cubic centimeter.

Answers

Answer: V= 330.513 cm 3

Step-by-step explanation:

Area = l x w and with a square the length and width are the same, additionally the volume of a pyramid can be found by using the formula (L)(w)(h)/3 so

8.7 x 8.7 = 75.69cm^2

75.69 x 13.1 = 991.539

991.539 ÷ 3 = 330.513 cm^3
