Step-by-step explanation:

Answer:

-6

Step-by-step explanation:

If the square root of a number is 6, then the number must be 36 (6*6=36)

However, negatives*negatives also equal positives, so

-6*-6 also =36

hence, your answer should be -6

Final answer:

The other square root of a number whose one square root is 6 is -6, because both 6 and -6 squared give the positive number 36.

Explanation:

The question you're asking pertains to finding square roots of a number. Given that one square root of a number is 6, the other square root would also be 6, but with an opposite sign, so it's -6. This is because when either 6 or -6 is squared (multiplied by itself), the result is 36. So, the number you're looking for is 36, and it has two square roots: 6 and -6. This is because the equation x² = √x holds true for both positive and negative values of x that yield the same positive result when squared.

To find the other square root of the number, we need to consider the fact that a positive number has two square roots - one positive and one negative.

Since the given square root is positive and equal to 6, the other square root would be its negative counterpart, which is -6.

letter answer

H

Answer:

(-5, 3)

Step-by-step explanation:

The smallest value y can have is just above -5 and the largest is just below 3.  Thus, the range of this function is (-5, 3).  This does not include -5 or 3.

Answer:

540 degrees.

Step-by-step explanation:

The formula for the sum of the interior angles is

S(n) = 180(n - 2)  where n = the number of sides.

For a pentagon, with 5 sides it is 180(5 - 2)

= 3*180

= 540 degrees.

Answer:

I think the answer is 540?

Step-by-step explanation:

The domain of the function for this situation is [8, 12].

The given function is c = 34.95u + 6.25, where c represents the total cost in dollars and u represents the number of uniforms bought.

To find the domain of the function for this situation, we need to determine the range of values that u can take within the given restrictions.

The question states that there should be at least 8 players but not more than 12 players on the volleyball team.

Therefore, the domain of the function is the set of numbers greater than or equal to 8 and less than or equal to 12. In interval notation, the domain can be represented as [8, 12].

Final answer:

The domain of the function c = 34.95u + 6.25 for the number of uniforms needed by a volleyball team is {8, 9, 10, 11, 12}, which corresponds to the number of players on the team, ranging from 8 to 12.

Explanation:

The function c = 34.95u + 6.25 represents the total cost to buy uniforms, where u is the number of uniforms. To determine the domain of this function based on the number of players, we note that there are at least 8 players and no more than 12 players on the volleyball team. Therefore, the number of uniforms (and hence the value of u) can range from 8 to 12, inclusive.

The domain of the function in this context is the set of whole numbers from 8 to 12. So, the domain is {8, 9, 10, 11, 12}.

Answer:

y + 1 - 5(x - 2)

Step-by-step explanation:

Borrow (2, -1):  Substitute 2 for x and -1 for y, and -5 for m in  y = mx + b:

-1 = -5(2) + b.  Then b = 9, and the desired equation in point-slope form is:

y - (-1) = -5(x - 2), or

y + 1 - 5(x - 2)

The point-slope form of a line with slope -5 that contains the point

(2,-1) is y+1=-5(x-2). Therefore, option B is the correct answer.

The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point.

The equation of the point slope form is: (y - y₁) = m(x - x₁)

where, (x, y) is a random point on the line and m is the slope of the line.

Given that, a line with slope -5 that contains the point (2, -1).

Substitute m=-5 and (x₁, y₁)=(2, -1) in the point slope form, we get

(y-(-1))=-5(x-2)

y+1=-5(x-2)

y+1=-5x+10

5x+y-9=0

Therefore, option B is the correct answer.

Answer: Bea's uncle is 25 years old.

Step-by-step explanation:

Given the equation [tex]3x- 15= 60[/tex], we can say that the variable "x" represents the age of Bea's uncle. Then to find his age, we need to solve for "x":

We must add 15 to both sides of the equation:

[tex]3x- 15+(15)= 60+(15)\\3x=75[/tex]

Now we need to divide both sides of the equation by 3:

[tex]\frac{3x}{3}=\frac{75}{3}\\\\x=25[/tex]

Therefore, we can conclude that Bea's uncle is 25 years old.

Answer:

[tex]330\ orcas[/tex]

Step-by-step explanation:

step 1

Find the total area of fictional Puget Loud

The area of the rectangular shape is

[tex]A=110*15=1,650\ mi^{2}[/tex]

step 2

Divide the total area by 5 mi² of territory per animal to find the number of orcas that could live in Puget Loud

[tex]1,650/5=330\ orcas[/tex]

Final answer:

To determine how many orcas could live in Puget Loud, calculate the total area (Length × Width) and divide it by the amount of space required per orca (5 mi²). The calculation gives us 330 orcas.

Explanation:

To estimate the number of orcas that could live in Puget Loud, we first need to calculate the total area of Puget Loud. We do this by multiplying the length by the width of the rectangular region.

Total area of Puget Loud = Length × Width
Total area of Puget Loud = 110 miles × 15 miles
Total area of Puget Loud = 1650 square miles

Next, we need to divide the total area of Puget Loud by the territory required per orca. Each orca requires approximately 5 square miles.

Number of orcas = Total area / Territory per orca
Number of orcas = 1650 mi² / 5 mi² per orca
Number of orcas = 330

Therefore, Puget Loud could potentially support 330 orcas.

If you want to look into it a little further, you can notice that if you sort the ordered pairs by their x-values, you get ...

(-1, 2), (0, 3), (1, 4)

That is, the y-values increase (by 1) as the x-values increase (by 1).

All of the other answer choices have -1 as the coefficient for x, which means the y-values will decrease as x increases. None of these choices (b–d) is viable.

Step-by-step explanation:

Final answer:

The scale factor of all radii of circle Y to all radii of circle Z is 0.4.

Explanation:

To find the scale factor of all radii of circle Y to all radii of circle Z, we can compare their radii.

Circle Y:
Center: (2,3)
Radius: 4

Circle Z:
Center: (2,-3)
Radius: 10

The scale factor is determined by comparing the radii of the two circles. The radius of circle Y is 4 and the radius of circle Z is 10. To find the scale factor, we divide the radius of circle Y by the radius of circle Z: 4/10 = 0.4.

Therefore, the scale factor of all radii of circle Y to all radii of circle Z is 0.4.

-0.75-(-2/5)+0.4+(-3/4) =  -0.7 simplified, how I got this answer can be found below in 16 steps.

1 - First thing we want to do is remove the parentheses.

-0.75 - (-2/5) + 0.4 - 3/4

2 - Then we simplify, multiply -1 by -1.

-0.75 + 1 (2/5) + 0.4 - 3/4

3 - Then multiply 2/5 by 1.

-0.75 + 2/5 + 0.4 - 3/4

4 - Then we want to write - 0.75/1 as a fraction with a common denominator, we do this by multiplying by 5/5.

-0.75/1 * 5/5 + 2/5 + 0.4 - 3/4

5 - Then we write each expression with a common denominator of 5, we multiply each one by a factor of one.

-0.75 * 5/1*5 + 2/5 + 0.4 - 3/4

6 - Then we multiply 5 by 1.

-0.75 * 5 / 5 + 2/5 + 0.4 - 3/4

7 - Then we combine the numerators over the common denominator.

-0.75*5+2/5+0.4-3/4

8 - We multiply -0.75 by 5.

-3.75 + 2/5 + 0.4 - 3/4

9 - Then we add -3.75 and 2.

-1.75/5+0.4-3/4

10 - And then we divide -1.75 by 5.

-0.35 + 0.4 - 3/4

11 - Then add -0.35 and 0.4.

0.05 - 3/4

12 - We then write 0.05/1 as a fraction with a common denominator, we do this via multiplying it by 4/4.

0.05/1 * 4/4 - 3/4

13 - Then we write each expression with a common denominator of 4, through multiplying each by a factor of 1.

0.05 * 4/4 - 3/4

14 - We combine the numerators over the common denominator.

0.05 * 4 - 3 / 4

15 - We simplify.

-2.8 / 4

16 - Then we divide -2.8 / 4

The final answer is -0.7
