Question:

Which of the equivalent expressions for P(x) reveals the profit when the price is

zero without changing the form of the expression? P(x) = -3x² + 432x - 1680

a) P(x) = -3(x - 4)(x - 140)

b) P(x) = -3(x - 72)² + 13872

Find the profit when the price is zero

Answer:

- P(x) = -3(x - 140)(x - 4).

- P(0) = -1680

Step-by-step explanation:

Given

P(x) = -3x² + 432x - 1680

Required

- Find equivalent of P(x)

- Find P(x) when x = 0

To find the equivalent of P(x), we simply factorize P(x) = -3x² + 432x - 1680.

This is done as follows

P(x) = -3x² + 432x - 1680

P(x) = -3x² + 12x + 420x - 1680

P(x) = -3x(x - 4) + 420(x - 4)

P(x) = (-3x + 420)(x - 4)

Further expand -3x + 420

P(x) = -3(x - 140)(x - 4).

Hence, the equivalent of

P(x) = -3x² + 432x - 1680

without changing its form is

P(x) = -3(x - 140)(x - 4).

When price is 0, then x = 0.

Substitute 0 for P(x) in P(x) = -3(x - 140)(x - 4).

P(0) = -3(0 - 140)(0 - 4).

P(0) = -3(-140)(-4)

P(0) = -1680

Hence, the profit when price is 0 is -1680

Answer:

Question 1: She needs 12 blue beads and 48 black beads.

Question 2: She needs 10 blue beads and 25 black beads.

Step-by-step explanation:

I used ratios

question one's ratio is 3:12 and the second one's ratio is 4:10. If you keep that ratio consistent than those are the numbers you get based on the number of beads long she wants her necklace.

that's my best guess

[tex]\frac{2}{3}[/tex]

[tex]\frac{4}{6}[/tex]

[tex]\frac{12}{18}[/tex]

[tex]\frac{14}{21}[/tex]

I hope this helps :)

Answer:

2/3= 4/6= 12/18= 14/21

Step-by-step explanation:

2/3= __/6

you know that that denominator doubles because 3*2=6, so what you do to the denominator you have to do to the numerator and vice versa. 2*2= 4 so the answer would be 4/6

To find 12/__

You should know that everything is equal to 2/3 in this equation. To get from 2 to 12 you need to multiply by 6. what you do to the top you have to do to the bottom. 3*6=18

_/21

You times 2/3 by 7 because 3*7=21.

2*7=14

Side length = 5.3851 inches

Step-by-step explanation:

area for square is given by [tex]side^2[/tex]

here area is given

lets calculate side now

[tex]29 = side^2\\=>\sqrt{29} =side \\=>5.3851[/tex]

Thus, we see length of side is 5.3851 which is greater than 5.35 and does not fall between 5.25 and 5.35.

An equation which should be used to calculate the volume of the geometric figure (see attachment) is: A. V = 1/3(6)4)(8).

Based on the geometric figure shown, we can logically deduce that it is a pyramid. Mathematically, the volume of a pyramid can be calculated by using this formula:

Volume = 1/3 × b × h

Where:

Substituting the parameters into the formula, we have:

Volume = 1/3 × 6 × 4 × 8

Volume = 1/3(6)4)(8).

Answer:

Table C is a linear function. Table A is an exponential function. And lastly table B is a quadratic function.

Step-by-step explanation:

I know that table C is linear because it has a constant rate of change the whole entire time.

I know table A is exponential because of the way it drastically increases at the end.

And lastly I know that table B is quadratic because if I were to graph it and keep on placing points, it would make a parabola.

Answer:

b = 6 mm

Step-by-step explanation:

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

b² + 8² = 10²

b² + 64 = 100 ( subtract 64 from both sides )

b² = 36 ( take the square root of both sides )

b = [tex]\sqrt{36}[/tex] = 6

b = 6 mm

Step-by-step explanation:

To find the missing side of a right triangle, we can use the Pythagorean theorem. This is...

[tex]a^2+b^2=c^2[/tex]

It is important to know that c will always be the hypotenuse, or in this case 10. We can plug everything we know from the picture into the theorem.

[tex]8^2+b^2=10^2[/tex]

[tex]64+b^2=100[/tex]

Subtract 64 from both sides.

[tex]b^2=36[/tex]

A lot of people make the mistake of thinking the final answer is 36, but since b is squared we need to find the square root of 36.

[tex]\sqrt{36}=6[/tex]

b = 6

Answer:

x = 5

y = 3

Step-by-step explanation:

9x and 45 are alternate interior angles, meaning they're congruent, so set them equal to one another, like so:

9x = 45

Divide both sides by 9:

x = 5

Solving for y, the two sides are of equal length, so set them equal:

6y = 18

Divide both sides by 6:

y = 3

Step-by-step explanation:

By alternate interior angle

9x=45°

x=5°

All parallel sides are equal in parallelogram

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

6, 2, 7, 12, 6, 1, 7, 1, 9, 7, 8

First put the numbers in order from smallest to largest

1,1, 2,6,6,  7, 7, 7, 8, 9, 12

The mean is adding all the numbers and dividing by the number of numbers

( 1+1+ 2+6+6+  7+ 7+ 7+ 8+ 9+ 12 )/11

66/1 =6

The mean is 6

The median is the middle

There are 11 terms

11/5 = 5.5  so 6 is the middle number

1,1, 2,6,6,    7,      7, 7, 8, 9, 12

7 is the median

Mode is the most often

7 appears three times so it is the mode

mutlak değerden + veya- çıkar.

|X-4|<3

-3 <x-4 <3

-3+4 <x <3+4

1 <x <7

The solution to the inequality |x-4| < 3 is x> 1 or x<7

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given:

An inequality,

|x-4| < 3.

Simplifying,

-3 < x - 4 < 3

Adding 4 to all sides,

1 < x < 7

Therefore, the solution is 1 < x < 7.

Answer:

Pet Hotel: 42.50 x + 64 y =277

Animal Spa: 35.50x + 50.5y = 225.50

Step-by-step explanation:

Hi, to answer this question we have to write an equation for each place:

For Pet Hotel, the total cost (277) must be equal to the product of the number of cats (x) and the charge per cat (42.50) plus the product of the number of dogs (y) and the charge per dog (64) .

Mathematically speaking:

Pet hotel: 42.5 x + 64 y =277

Same process for Animal Spa:

Animal Spa: 35.5 x + 50.5y = 225.50

The system is:

42.5 x + 64 y =277 (Pet Hotel)

35.5 x + 50.5y = 225.50 (Animal Spa)

Answer:

no solutions

Step-by-step explanation:

-(2x + 4) + x = 3x − 4x − 4

Distribute

-2x - 4 + x = 3x − 4x − 4

Combine like terms

-x +4 = -x -4

Add x to each side

-x+x+4 = -x+x-4

4 = -4

This is never true so there are no solutions

Answer:

Infinite number of solutions

Step-by-step explanation:

-(2x + 4) + x = 3x − 4x − 4

-2x - 4 + x = -x - 4

-x - 4 = -x - 4

-4 = -4

This equation remains true for all x,

Hence infinitely many solutions

Step-by-step explanation:

Answer:

A =63.585  units^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2 where r is the radius

We have a diameter of 9

r = d/2 = 9/2 = 4.5

A = (3.14) * (4.5)^2

A =63.585  units^2

Answer:

x = 45

y = 20

Step-by-step explanation:

Set the x-variables and y-variables with its corresponding ones, like so:

4x - 35 = 3x + 10

Subtract 3x from both sides:

x - 35 = 10

Add 35 to both sides:

x = 45

Solving for y:

2y - 5 = y + 15

Subtract y from both sides:

y - 5 = 15

Add 5 to both sides:

y = 20

Answer:

By vertically opposite angle

2y-5=y+15

y=20°

4x-35=3x+10

x=45°

Answer:

12

Step-by-step explanation:

It takes twelve 1/20 tiles to exactly cover three 1/5 tiles, so 35=12/20.

The number of twentieths required to make three fifths is required.

Twelve twentieths equal to three-fifths

The question can be rephrased as "How many times do you have to add [tex]\dfrac{1}{20}[/tex] to get [tex]\dfrac{3}{5}[/tex]"

The end result should be [tex]\dfrac{3}{5}[/tex]

Let the number of times be [tex]x[/tex]

[tex]x\times \dfrac{1}{20}=\dfrac{3}{5}\\\Rightarrow x=\dfrac{3}{5}\times 20\\\Rightarrow x=12[/tex]

So, twelve twentieths equal to three-fifths.
