Answer:

ayannah is correct

Step-by-step explanation:

Ayannah is correct becauseyou can divide both 19 and 133 by 19 which gives you 1/7. 1/7 isn't divisible by anything else so that's the simplest form.

Answer:

Ayanna is correct because 19/133= 1/7

Step-by-step explanation:

Simplest form means reducing fractions to its lowest term.

The height of the cannonball not equal to 0 when time equals 0 because initial height of the cannonball is above the ground

From the graph, we have the y-intercept to be

y-intercept = (0, y), where y > 0

This means that the graph starts above the origin

This in other words mean that the initial height of the cannonball is above the ground (e.g. it could be on a building)

Hence, the height of the cannonball not equal to 0 when time equals 0 because initial height of the cannonball is above the ground

In this case, the domain is from t = 0 till the ball lands on the floor, while the range is from the initial height of the cannonball till the maximum height

The area of circle of diameter 10 inches is 25π in.² and,

area of circle of radius 8 cm is 64π cm².

How is Area of circle is calculated ?

Area of circle is calculated using formula :

A = πr²

1) It is given that diameter of circle is 10 inches then the radius will be half of it that is :

d = 10 inches

r = 5 inches

Now calculating the area of circle using the above formula :

A = πr²

A = π(5)²

A = 25π in.²

2) It is given that radius of circle is 8 cm then calculating area using above formula :

A = πr²

A = π(8)²

A = 64π cm²

Therefore, the area of circle of diameter 10 inches is 25π in.² and,

Answer: wouldn't that be 10 feet and 8 feet?

Step-by-step explanation:

because they both are the same size on both sides

and i have no clue if that helped

Answer:

Area of two rooms is 357 square feet

Length of the baseboards = 89.5 ft

Step-by-step explanation:

Area of the room = length * width

Area of the two rooms = area of bigger room + area of smaller room

                                       = 19 * 15 + 8 * 9

                                        = 285 + 72

                                        = 357 square feet

To find the length of the baseboard, we need to subtract the width of the opening (5 feet) and width of the entry (2 1/2 feet) from the perimeter of the bigger room and subtract the width of the opening (5 feet) from the perimeter of the smaller room.

Bigger room:

length = 19 ft

Width = 15 ft

Width of the entry =  2 1/2 ft = 2.5 ft

Width of the opening between two rooms = 5 ft

Perimeter of bigger room = 2l + 2w - 5 - 2.5

                                          = 2*19 + 2*15 - 7.5

                                          = 38 + 30 - 7.5

                                           = 60.5 ft

Smaller room:

length =  8ft

Width = 9 ft

Width of the opening = 5 ft

Perimeter of the smaller room = 2*8 + 2*9 - 5

                                                   = 16 + 18 - 5

                                                   = 29 ft

Length of the base board = 60.5 + 29

                                           = 89.5 ft

Answer:

10 is the jk because x + 8 is 10

I hope it will help

Answer:

11 units

Step-by-step explanation:

It's clear that,

JL = JK + KL

Given that,

JK ⇒ ( x + 8 )

KL ⇒ 10

JL ⇒ 7x

So, by using these data we can make an expression like this.

JL = JK + KL

7x = x + 8 + 10

Now make x the subject and find the value of x.

7x = x + 8 + 10

7x = x + 18

7x - x = 18

6x = 18

6x/6 = 18/6

x = 3

And now let us find the value of JK.

JK ⇒ x + 8

To, find the value of JK we have to replace with 3.

JK ⇒ x + 8

JK ⇒ 3 + 8

JK ⇒ 11 units

Answer:

{-12, 8}

Step-by-step explanation:

Let's solve your equation step-by-step.

|p+2|=10

Solve Absolute Value.

|p+2|=10

We know eitherp+2=10orp+2=−10

p+2=10(Possibility 1)

p+2−2=10−2(Subtract 2 from both sides)

p=8

p+2=−10(Possibility 2)

p+2−2=−10−2(Subtract 2 from both sides)

p=−12

The range is the set of y outputs. In this case, the range is the profit.

A negative profit means the company lost money. This is when the cost is larger than the revenue. For instance, if the revenue was $100 but the cost is $150, then the profit = revenue - cost = 100-150 = -50 to signal they lost $50.

Positive profit means the company made money.

The x intercept represents the break-even point. This is where the company neither loses money, nor gains money. The profit is $0 here.

Answer/Step-by-step explanation:

In order to open a restaurant you have to rent a venue, furnish and decorate it, hire a staff and buy food and drinks. Before serving (selling) any meals you have to spend a lot of money. This is why the negative y-values.

At the point where the line crosses the x-axis (horizontal axis) you now begin to have a positive output to your operation. If you sell enough meals, you will turn a profit. That is, you make enough money to pay all those start-up expenses and still have money left over to keep!

The solution of y are 1.82 and -0.22

The general expression for quadratic equation is given as :

                  ax² + bx + c = 0

The quadratic formula of the above equation is given as

              x = -b ± √b²-4ac / 2a

According to the question we have been the expression as

          5y² - 8y = 2

Converting it into general expression we get

         5y² - 8y - 2 = 0

Putting the required value in above quadratic formula we get

    y = -(-8) ± √(8)² - 4*5*(-2) / 2*5

    y = 8 ± √64 + 40 / 10

    y = 8 ± √104 / 10

    y = (8 ± 10.2)/10

y = 8 + 10.2 / 10       and    y = 8-10.2 / 10

y = 18.2 / 10              and    y = -2.2/10

y = 1.82               and   y = -0.22

Hence the solution of y are 1.82 and -0.22

The curve intersects the vertical lines when

[tex]x=2 \implies y = \dfrac1{2+2^3} = \dfrac1{10}[/tex]

and

[tex]x=3 \implies y = \dfrac1{2+3^3} = \dfrac1{29}[/tex]

Split up the region into washers of thickness [tex]\Delta y[/tex].

For [tex]-1\le y\le\frac1{29}[/tex], the inner and outer radii of each washer will be constant, with outer radius [tex]x=3[/tex] and inner radius [tex]x=2[/tex]. Each washer in this interval will contribute a total volume of

[tex]\pi (3^2 - 2^2) \Delta y = 5\pi\,\Delta y[/tex]

For [tex]\frac1{29} \le y \le \frac1{10}[/tex], the washers will have a varying outer radius of length

[tex]y=\dfrac1{2+x^3} \implies x = \sqrt[3]{\dfrac1y - 2}[/tex]

and inner radius [tex]x=2[/tex]. Their volumes are

[tex]\pi \left(\left(\sqrt[3]{\dfrac1y - 2}\right)^2 - 2^2\right) \, \Delta y = \pi \left(\left(\dfrac1y - 2\right)^{2/3} - 4\right) \, \Delta y[/tex]

Let [tex]\Delta y\to0[/tex]. Then as the number of washers goes to infinity, the total volume of the solid converges to the definite integral

[tex]\displaystyle 5\pi \int_{-1}^{1/29} dy + \pi \int_{1/29}^{1/10} \left(\left(\dfrac1y - 2\right)^{2/3} - 4\right) \, dy[/tex]

The first integral is trivial, but the second one requires hypergeometric functions to evaluate exactly. With a calculator, we find the approximate volume to be 0.117884.

Answer: x=3

Step-by-step explanation:

2(4x - 3) - 8 = 4 + 2x

8x - 6 - 8 = 4 + 2x

8x - (6 + 8) = 4 + 2x

8x - 14 = 4 + 2x

8x - 14 + 14 = 4 + 14 + 2x

8x = 18 + 2x

8x - 2x = 18 + 2x - 2x

6x = 18

6x/6=18/6

x=3

x = 3

first you want to distribute 2 to 4x and -3

8x-6 -8 = 4 +2x

then you subtract the numbers on the left side

8x-6-8
8x-14= 4 +2x

then we want to rearrange the 4 and 2x

8x - 14 = 2x+4

the add 14 to each side and move 2x to both sides

6x=18

then divide

x=3

Answer:

Choice A: 11

Step-by-step explanation:

We have x² - y² = 19

x² - y²  = (x + y)(x-y)

So (x + y)(x-y) = 19

Since x and y are integers as per the first statement (x, y ∈ Z), we also have x + y = integer and x-y = integer

Take (x + y)(x - y) = 19

Since 19 is prime its only factors are 1 and 19

So we have two situations which can satisfy the above
Either x + y = 1 and x -y  19 or x + y = 19 and x -y = 1

1. Let's try x + y = 1 and x - y = 19
Adding both equations together gives us 2x = 20 (y-terms cancel)

==> x = 10 ==> 10 + y = 1 or y = -9

So 2x - 9 => 2(10) - (-9)  = 20 + 9 = 29

This is not one of the choices so we can go on to the next case

2 Let's take x + y = 19 and x - y = 1

Adding these two equations gives us
2x = 20, x = 10 as before

Use 10 in the equation x + y = 19

==> 10 + y = 19

==> y = 19 - 10 = 9

2x - y ==> 2(10) - 9 ==> 20 - 9 = 11

So answer is choice A:  11
