$\text{Given that,}\\\\(x_1,y_1) = (4,-2)~~ \text{and}~~ (x_2 ,y_2) = (4,-5)\\\\\text{Distance} = \sqrt{(x_2-x_1)^2 + (y_2 -y_1)^2}\\\\~~~~~~~~~~~~=\sqrt{(4-4)^2 + (-5+2)^2}\\\\~~~~~~~~~~~~=\sqrt{0^2+(-3)^2}\\\\~~~~~~~~~~~~=\sqrt{0+9}\\\\~~~~~~~~~~~~=\sqrt 9\\\\~~~~~~~~~~~~=3$

nida is buying a small storage box online. She sees a cube box with volume of 125cm^3. What is the length of each box edge?

aleksklad [387]

Answer:

5 cm

Step-by-step explanation:

Here, we want to get the length of each box edge

Let the length be s

Mathematically, the volume of a cube is s^3

Thus;

s^3 = 125

s^3 = 5^3

s = 5 cm

Answer:

$b = 90$

$c=80$

$d =100$

Step-by-step explanation:

Given

See attachment

Required

Find b, c and d

First, we solve for b using:

$b + 10 + b - 10 = 180$ --- base angles of a parallelogram

Collect like terms

$b + b =180+10-10$

$2b = 180$

Solve for b

$b = 180/2$

$b = 90$

Then, we have:

$d =b + 10$

$c = b - 10$ --- opposite angles

So, we have:

$d =90 + 10$

$d =100$

$c = 90 - 10$

$c=80$

the absolute value of the sum of two different integers with the same sign is 8. Pat says there are three pairs of integers that

Irina18 [472]

Disagree
They say there are three pairs of integers that match, well..
1+7=8
2+6=8
3+5=8

-1+-7=-8
-2+-6=-8
-3+-5=-8
The same applies to negative integers because the absolute value of -3 and 3 is still 3. No matter the negative or not. So that gives us 6 pairs not 3.

Answer: C.

Simple random sampling

Step-by-step explanation:

A simple random sample in statistics, is a subset of individuals chosen from a larger set. Each individual is chosen randomly and entirely by chance, such that each individual has the same probability for the entire larger set.

How do you find the missing length

uranmaximum [27]

To find the missing length of a triangle we will use the Pythagorean Theorem.
Pythagoream Theorem = a^2 + b^2 = c^2
With this formula, we can find the missing side as follows:
27^2 + 36^2 = c^2
729 + 1,296 = C
2,025 = C
45 = C^2
There for we can conclude that the answer for the missing side is: 45 inches.
