Answer:

  A|  12, 3

Step-by-step explanation:

The polynomial can be factored by looking for factors of 36 that sum to -15. The sum being negative while the product is positive means both factors will be negative. The answer choices suggest ...

  y = (x -12)(x -3)

A quick check shows this product is ...

  y = x^2 -12x -3x +36 = x^2 -15x +36 . . . . as required

The factors are zero when x is either 12 or 3.

The zeros of the equation are 12 and 3.

Answer:

The center is (0,0) and the radius is 5

Step-by-step explanation:

To find the center of a circle, you need to look at the equation

In this case this equation could be written as

[tex](x-0)^2+(y-0)^2=5^2[/tex]

The x value is x=0 for the center and the y values is y=0

The radius can be found by looking at the constant that is squared, so r=5

In the case of an equation like this

[tex](x-1)^2+(y+1)^2=3^2[/tex]

The center point would be (1,-1) and r=3

12• (-5)= - 120/2 = -60

ANSWER

The product is

EXPLANATION

We want to find the product of 12 and -5.

This means that we should find the result of multiplying 12 and -5

Recall that:

[tex]12 \times 5 = 5 \times 12 = 60[/tex]

Therefore,

[tex]12 \times ( - 5) = - 5 \times 12 = 60[/tex]

The product is -60

The question is incomplete, the complete question is Angela makes a pillow in the shape of a wedge to use for watching TV. The pillow is filled with 12 ft³ of fluffy material. The base is 3 ft, the height is 2 ft, what is the length of the pillow?

The length of the pillow is 4 feet

Step-by-step explanation:

The formula of the volume of the wedge is [tex]V=\frac{1}{2}bhl[/tex] , where

∵ The pillow in the shape of a wedge

∵ The pillow is filled with 12 ft³ of fluffy material

∴ The volume of the wedge = 12 ft³

∵ The base = 3 feet

∵ The height = 2 feet

- Use the formula of the volume above to find its length

∵ [tex]V=\frac{1}{2}(2)(3)l[/tex]

∴ V = 3 l

∵ V = 12 ft³

- Equate 3 l by 12

∴ 3 l = 12

- Divide both sides by 3

∴ l = 4 feet

∴ The length of the pillow is 4 feet

Answer:

3.30 for apple and 2.00 for an orange

Step-by-step explanation:

To solve this problem, we can set up a system of linear equations to represent the charges for apples and oranges at the fruit stand. We can then solve this system using the elimination method to find the cost of an apple and an orange.

To solve this problem, we can set up a system of linear equations to represent the charges for apples and oranges at the fruit stand. Let's use x to represent the cost of an apple and y to represent the cost of an orange.

From the given information, we can set up the following equations:

111x + 111y = 5.30

111x + 222y = 7.30

Next, we can solve this system of equations by using substitution or elimination. Let's use the elimination method:

Multiply the first equation by 2, and multiply the second equation by 1:

222x + 222y = 10.60

111x + 222y = 7.30

Subtract the second equation from the first:

111x = 3.30

Divide both sides by 111:

x = 0.03

Substitute this value back into either equation to solve for y:

111(0.03) + 222y = 7.30

3.33 + 222y = 7.30

222y = 3.97

y = 0.01

Therefore, the cost of an apple is $0.03 and the cost of an orange is $0.01 at the fruit stand.

The line integral over the path C from (0,0,0) to (1,3,6) can be converted into an ordinary integral by parameterizing the line segment and then substituting in the integral. The result of the integral amounts to 5.

The given integral involves a line segment from (0,0,0) to (1,3,6). Our task is to convert this line integral to an ordinary integral.

The path C from (0, 0, 0) to (1, 3, 6) can be parameterized as r(t) = ti + 3tj + 6tk for 0 ≤ t ≤ 1. So, the dr = dt(i + 3j + 6k).

Substituting for ds in the integral, we get: ∫ r(t)dt from 0 to 1, which can be reduced to three separate integrals with respect to x, y, and z respectively: ∫xdx from 0 to 1, ∫3ydy from 0 to 1, and ∫6zdz from 0 to 1. Now these can be easily integrated.

So, the solution will be:
∫xdx from 0 to 1 = [x^2/2] from 0 to 1 = 1/2,
∫3ydy from 0 to 1 = [3y^2/2] from 0 to 1 = 3/2,
∫6zdz from 0 to 1 = [6z^2/2] from 0 to 1 = 3.

Adding these up gives the result of the original line integral, which is 5.

Calculate the total wall and ceiling area, then determine the number of gallons of paint needed using the given coverage per gallon.

To calculate the total wall and ceiling area:

Calculate the total wall area: (2 x 12 x 7) + (2 x 15 x 7) = 168 + 210 = 378 square feet.

Add the ceiling area: 12 x 15 = 180 square feet.

Sum the wall and ceiling areas: 378 + 180 = 558 square feet.

To determine how many gallons of paint:

Divide the total area by the coverage of one gallon: 558 ÷ 250 = 2.232 gallons (round up to ensure enough paint).

You would need approximately 2.232 gallons of paint to paint the walls and ceiling of the bedroom.

To find the total area that needs to be painted, we first calculate the area of the walls and the ceiling.

1. Area of the walls:

The bedroom has four walls, two of which are 12 feet by 7 feet and the other two are 15 feet by 7 feet.

Total area of the walls = 2(12 * 7) + 2(15 * 7) = 2(84) + 2(105) = 168 + 210 = 378 square feet

2. Area of the ceiling:

The ceiling is the same size as the floor, which is 12 feet by 15 feet.

Area of the ceiling = 12 * 15 = 180 square feet

3. Total area to be painted:

Total area = Area of walls + Area of ceiling = 378 + 180 = 558 square feet

4. Gallons of paint needed:

Since one gallon of paint covers 250 square feet, we divide the total area by the coverage of one gallon:

Gallons needed = Total area / Coverage per gallon = 558 / 250 ≈ 2.232 gallons

Therefore, you would need approximately 2.232 gallons of paint to paint the walls and ceiling of the bedroom.

Length of radius = [tex]5\sqrt{2}[/tex]

Step-by-step explanation:

The radius of the circle is the distance between the center and the point on the circle given.

The distance formula is  [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

Where

x_1 = 0

y_1 = -6

and

x_2 = 5

y_2 = -1

plugging these into the formula we get:

[tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2} \\=\sqrt{(-1-(-6))^2+(5-0)^2} \\=\sqrt{(-1+6)^2+(5)^2} \\=\sqrt{5^2 + 5^2} \\=\sqrt{50} \\=5\sqrt{2}[/tex]

Answer:

The radius of circle = 5√2 units

Step-by-step explanation:

Points remember

Distance formula:-

Let (x₁, y₁) and (x₂, y₂) be the two points, then the distance between these two points is given by

Distance = √[(x₂ - x₁)² + (y - y₁)²]

It is given that, center of circle (0, -6) and passes through (5, -1)

To find the radius of circle

Here (x₁, y₁) = (0, -6) and (x₂, y₂) = (5, -1)

Radius r = √[(x₂ - x₁)² + (y - y₁)²]

  = √[(5 - 0)² + (-1 - -6)²]

  = √(5² + 5²) = √(25 + 25) = √50 = 5√2 units

Therefore radius of circle = 5√2 units

Answer:

8.5

Step-by-step explanation:

Twice the difference of a number and 6 equals 5 is written algebraically as 2(x-6)=5, where x is the number. Solving for x:

2(x-6)=5

(x-6)=5/2

x=6+5/2

x=17/2

So the number is 17/2, or, expressed as a decimal number, 8.5

We solve the equation 'Twice the difference of a number and 6 equals 5' by identifying variable 'x' as the unknown number, rearranging the equation, and then performing a series of number operations (multiplication, addition, and division) to find x = 8.5.

In the given problem, you are asked to solve for a number in the equation 'Twice the difference of a number and 6 equals 5'. We denote the unknown number we’re looking for as ‘x’. Thus, the equation becomes 2(x - 6) = 5.

By solving this equation step-by-step, we first distribute the 2 to both terms in the parentheses. This key step gives us 2x - 12 = 5.

Next, we add 12 to both sides to isolate 2x on the left side, which gives 2x = 17.

Finally, we divide both sides by 2 to solve for x, giving us x = 17 / 2 or 8.5.

In conclusion, the unknown number x that satisfies the condition 'Twice the difference of a number and 6 equals 5' is 8.5.
