Answer:
a number which produces a specified quantity when multiplied by itself
Step-by-step explanation:
The square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 9 is 3, because 3 x 3 = 9. The symbol for the square root is "√". So, √9 = 3.
There are two types of square roots: the principal square root and the negative square root. The principal square root is the positive value that, when multiplied by itself, gives the original number. The negative square root is the negative value that, when multiplied by itself, gives the original number. For example, the square roots of 9 are 3 and -3, because both 3 x 3 = 9 and -3 x -3 = 9.
The square root of a number can be approximated using a calculator or can be found using mathematical techniques such as the Newton-Raphson method. The square root of a number can also be expressed as an irrational number, meaning that it cannot be expressed as a fraction of two integers. For example, the square root of 2 is an irrational number that cannot be expressed exactly as a fraction.

Required Information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Show that if n is an integer and m+ 5 is odd, then n is even using a proof of contraposition. Rank the options below. We can write n = 2k +1 for some integer k. As n + 5 Is two times an integer, it is even. Assume that n is odd. Thus, if n is odd, then 3 + 5 is even. Then, 13 + 5 = (2K+993 +5=863 +1242 +66+6 = 2(4x3 +672 + 3k + 3).
If n is an integer and m + 5 is odd, then n must be even.
To prove this statement using contraposition, we need to show that if n is odd, then m + 5 must be even. Assume that n is odd, which means we can write n = 2k + 1 for some integer k.
Then, we can rewrite m + 5 as (2k + 1) + 5 = 2k + 6 = 2(k + 3), which is even.
Therefore, we have shown that if n is odd, then m + 5 is even.
By contraposition, we can conclude that if m + 5 is odd, then n must be even. Overall, the proof uses the fact that odd + odd = even and even + odd = odd, along with the definition of even and odd integers.

Indentify any vertical asymptotes and holes of f(x)= x^2+6x+9/x^2-9
The vertical asymptote of the function [tex]f(x) = \frac{x^2 + 6x + 9}{x^2 - 9}[/tex] is at x = 3.
What is an asymptote?Asymptote is a line or curve that serves as the boundary of another line or curve in mathematics.
Given, A function [tex]f(x) = \frac{x^2 + 6x + 9}{x^2 - 9}[/tex].
Factoring the numerator and the denominator we have,
[tex]f(x) = \frac{(x+3)(x+3)}{(x+3)(x-3)}[/tex]
Now, The holes of the function are at [tex]f(x) = \frac{(x+3)}{(x-3)}[/tex], x + 3 = 0, x = - 3.
And the asymptote of the function is at x - 3 = 0, x = 3.
Therefore, The asymptote will be a dotted vertical line at x = 3.

meters from ground level? Round your answer to two decimal places.
Gravity Formula
The rock will be 9 meters from ground level at a time of:
x = 5.76 seconds.
How to model the situation?The quadratic function that models a projectile's height is given as follows:
y = -4.9t² + v(0)t + h(0)
In which:
v(0) is the initial velocity.h(0) is the initial height.The parameters for this problem are given as follows:
v(0) = 22, h(0) = 45.
Hence the height function is given as follows:
y = -4.9t² + 22t + 45.
The rock is 9 meters from ground level when:
9 = -4.9t² + 22t + 45.
-4.9t² + 22t + 36 = 0
4.9t² - 22t - 36 = 0.
Hence the discriminant is given as follows:
D = 22² - 4(4.9)(-36)
D = 1189.6.

Choose 1 answer:
WILL GIVE ALL MY PONITS
Answer:
Veronica's attempt at ordering the hikes from least to greatest by the number of animals seen per kilometer is not correct.
To order the hikes by the number of animals seen per kilometer, we need to calculate the number of animals seen per kilometer for each hike. We can do this by dividing the number of animals seen by the length of the hike in kilometers.
Using this method, we can calculate the number of animals seen per kilometer for each hike as follows:
Rivers Edge: 8/3 = 2.67 animals/km
Wooded Marsh: 24/8 = 3 animals/km
Canyon Creek: 35/15 = 2.33 animals/km
Based on these calculations, the correct order of the hikes from least to greatest by the number of animals seen per kilometer is Rivers Edge, Canyon Creek, Wooded Marsh.
Veronica's mistake appears to be that she simply ordered the number of animals seen in each hike from least to greatest, rather than calculating the number of animals seen per kilometer.
Mr.Aba builds a circular patio with a diameter of 12 feet.He covers the patio with paving stones.The cost of the paving stones is $10.50 per square foot.To the nearest dollar,how much do the paving stones cost?
The total cost of the paving stones for building a circular patio with a diameter of 12 feet is C. $1,187.
How is the total cost determined?The area of the circular patio using its diameter and pi (22/7) is determined with the formula below.
The unit cost per square foot is multiplied by the area to determine the total cost.
A = π (d/2)^2
The diameter of a circular patio = 12 feet
The area, A = π (d/2)^2
= 22/7(12/2)^2
= 113.14 ft²
The cost per square foot of paving stones = $10.50
The total cost = $1,187.97 ($10.50 x 113.14)
= $1,188

prove that for every positive rational number r satisfying the condition r2<2 one can always find a larger rational number r h (h>0 ) for which (r h)2<2 .
Answer: Suppose there exists a positive rational number r such that r^2 < 2. Then we have 2 - r^2 > 0. Let h = (2 - r^2)/4. Then h > 0 because r^2 < 2.
Consider the number rh = r + h. We have:
(rh)^2 = (r + h)^2 = r^2 + 2rh + h^2 = r^2 + 2(2 - r^2)/2 + (2 - r^2)/16
= r^2 + 2 + (2 - r^2)/16
< 2 + 2 + (2 - 2)/16 = 2.
Thus, for any positive rational number r such that r^2 < 2, there exists a larger positive rational number rh = r + h such that (rh)^2 < 2.

find mGHJ in degrees inscribed angles
If the measure of the intercepted arc GHJ is 180°, the measure of the inscribed angle GHJ will be mGHJ = 360° - 180° = 180°.
What is angle?Angel is a geometric figure that can be described as the amount of rotation between two straight line or planes and angles is measured in degree with the full circle being 360°.
The measure of an inscribed angle in a circle is always equal to the measure of its intercepted arc. The measure of the arc intercepted by a central angle is determined by the formula, mGHJ = 360° - mJKH. Therefore, the measure of an inscribed angle in a circle with intercepted arc GHJ is equal to mGHJ = 360° - mJKH. This means that the measure of an inscribed angle in a circle can vary depending on the measure of its intercepted arc. For example, if the measure of the intercepted arc GHJ is 180°, the measure of the inscribed angle GHJ will be mGHJ = 360° - 180° = 180°.

1/5 x 10 multiply fractions: parts of a group
Two buckets, each with a different volume of water, start leaking water at the same time, but at different rates. Assume the volumes are changing linearly.
The difference between the starting volumes is 200 milliliters, the first bucket has the larger volume.
What is the difference between the starting volumes?We know that the volumes can be modeled by linear equations, and remember that a general linear equation is:
y = a*x + b
Where a is the slope and b is the initial value.
If the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
For the first bucket we have the points (1, 2900), (10, 2000), then the slope is:
a = (2000 - 2900)/(10 - 1) = -900/9 = -100
So we can write:
y = -100*x + b
To find the value of b, we can replace the value of one of the points in the equation. I will use the first point (1, 2900)
2900 = -100*1 + b
2900 + 100 = b
3000 = b
Now for the other bucket, we have the points (1, 2725) and (10, 2050), so the slope is:
a = (2725 - 2050)/(10 - 1) = -75
So this line is:
y = -75*x + b
Again, replacing the values of one of the points we will get:
2725 = -75*1 + b
2725 + 75 = b
2800 = b
Then the difference in the starting volumes is:
3000 - 2800 = 200
The first bucket has 200 milliliters more.

A total of 3 ft falls over 3 days. On the first day, 1/6 of the total rain falls. On the second day, 7/12 of the total rain falls. How much rain falls each day in inches? Show your work. Please help.
Answer:
Day 1: 6 inches
Day 2: 21 inches
Day 3: 9 inches
Step-by-step explanation:
First, we need to convert the total rainfall from feet to inches. Since 1 foot is equal to 12 inches, 3 feet is equal to 36 inches.
On the first day, 1/6 of the total rainfall falls, so:
(1/6) * 36 = 6 inches
On the second day, 7/12 of the total rainfall falls, so:
(7/12) * 36 = 21 inches
To find the rainfall on the third day, we can subtract the rainfall on the first and second days from the total rainfall:
36 - 6 - 21 = 9 inches
Therefore, the amount of rainfall on each day, in inches, is:
Day 1: 6 inches
Day 2: 21 inches
Day 3: 9 inches
