Since both x values are the same and since the y values are 18 digits apart, the distance between both points is 18 units.

To find the distance, you would use the <u>distance formula</u>, which is:

\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}}

But, in this case, both of the x values are 13, meaning we can cancel out the x values (or just subtract y₁ from y₂, to get the distance ):

\sqrt{(13 - 13)^{2} + (y2 - y1)^{2}}

\sqrt{(0)^{2} + (y2 - y1)^{2}}

\sqrt{0 + (y2 - y1)^{2}}

Because of this, we only need to find the distance between y₁ and y₂. Plug in the -6 and 12:

\sqrt{(12 + 6)^{2}}     <em>Plug in both y terms.</em>

\sqrt{18^{2}}     <em>Simplify as much as possible.</em>

= 18     <em>The √ and the ² cancel out.</em>

Therefore, the distance between (13, -6) and (13, 12) is 18.

<em>Hope this helps! :)</em>

ludmilkaskok [199]

Answer:

11  feet away.

Step-by-step explanation:

Given:

A water and sprinkle our sins water out in a circular pattern

Area formed by the watering pattern is 379.94 square feet

To find:

How many feet away can it spread water means we have to find distance from the middle point to the last end of circular pattern of water sprinkling (radius of a circle) = ?

solution:

By using ,Area of a circle = \pi r^{2}

Area of a circle = 379.94 square feet  (given)

\pi r^{2} = 379.94

3.14\times r^{2}  = 379.94\\

Dividing both side by 3.14

r^{2}  = \frac{379.94}{3.14}  = 121

Taking square root both side

r = \sqrt[2]{11\times11}        (Taking common)

r = 11

Therefore, radius = 11

Thus,  it can  spread water 11  feet away.

A the bead shop, there are 25 rows of beads. If there are 320 beads in each row, how many beads are in the shop?
chubhunter [2.5K]
The answer would be 8,000 because one row = 320 beads, and 25x320=8,000

If one of the zeros of the cubic polynomial x3 + ax2 + bx + c is -1, then what will be the product of the other two zeros?
zhenek [66]

Answer:

The product of the other two zeros is c

Step-by-step explanation:

Let α, β and γ be the zeros of the polynomial x³ + ax² + bx + c. Since one of the zeros is -1, therefore let γ = -1. Hence:

sum of the roots = α + β + γ = -a

-1 + β + γ = -a

β + γ = -a + 1

αβ + αγ + βγ = b

-1(β) + (-1)γ + βγ = b

-β -γ + βγ = b

Also, the product of the zeros is equal to -c, hence:

αβγ = -c

-1(βγ) = -c

βγ = c

Hence the product of the other two zeros is c
