Answer:

Step-by-step explanation:

The square root is only defined for arguments that are greater than or equal to zero.

  √x . . . . defined for x ≥ 0

It will only have non-negative values.

  √x . . . . has values ≥ 0

Using these facts, we can answer the questions.

__

1. The domain is the set of values x may have. The square root function limits the domain to x ≥ 0.

__

2. The range is the set of values y may have. The square root function is never negative, so the range must be 2 or greater.

  y ≥ 2

Answer:

1/6 mile

Step-by-step explanation:

Distance divided = 1/2 miles

No of sections = 3

Each division must equal = 1/2/3

                             = 1/2*1/3 = 1/6 mile.

The distance between each of the signs i.e between the first and second , second and third is 1/6 of the mile.

This can be done in decimals as well

1/2 mile= 0.5 mile.

When we divide 0.5 mile by 3 we get  0.167 which is equal to 1/6 in fractions.

Answer:

Yes, that is enough statistical evidence to suggest to conclude that residents of Legacy Ranch use less water on average

Step-by-step explanation:

The data given by the American Water Works Association are;

The per capita water use in a single-family home, μ = 76 gallons per day

The number of responders in the sample, n = 27

The sample mean water used by the sample, [tex]\overline x[/tex] = 71 gallons

The standard deviation, s = 9.5 gallons per day

The level of significance, α = 0.01

The test statistics is given as follows;

The null hypothesis, H₀; μ ≥ 76 gallons

The alternative hypothesis, Hₐ; μ < 76 gallons

[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex]

Therefore, we have;

[tex]t=\dfrac{71-76 }{\dfrac{9.5}{\sqrt{27}}} \approx -2.734817[/tex]

At n - 1 = 27 - 1 = 26 degrees of freedom, the critical-t = 2.5

From the test statistic, of t ≈ -2.734817, the p-value < 0.01, and from a graphing calculator, the p-value is given as Prob = 0.005544418

Therefore, given that the p-value is less the significant level, and less than 0.01, is therefore statistically significant, and therefore, there is sufficient statistical evidence against the null hypothesis, therefore we reject the null hypothesis, and there is enough statistical evidence to suggest to conclude that residents of Legacy Ranch use less water on average.

Answer:

x = 1.3

Step-by-step explanation:

Eliminate fractions first.  Multiply all four terms by 100.  The result will be:

380 + 450x - 140 = 825

Combine like terms:

240 + 450x = 825, or

585 = 450x, or:

x = 1.3

Answer:

r = 6 inch

Step-by-step explanation:

Given that,

The height of a cone, h =8 inches

The slant height of the cone, l = 10 inches

We need to find the radius of the base. The relation between height, radius and the slant height of the cone is given by :

[tex]r=\sqrt{l^2-h^2} \\\\r=\sqrt{10^2+8^2} \\\\r=6\ inch[/tex]

So, the radius of its base is equal to 6 inches.

Answer:

The answer is D.

Step-by-step explanation:

Answer:

the correct option is 75

Step-by-step explanation:

The standard notation for how to write tables is in the next way.

[tex]\left[\begin{array}{ccc}inpt&outpt\\x_1&y_1\\x_2&x_2\end{array}\right][/tex]

Where the input values are represented in the x-axis (the horizontal one) and the output values are on the y-axis (the vertical one).

In this case, we want to find the number of (x-value) for the height of 250.

Then we need to look at the vertical axis and find the value y = 250.

Now let's move to the right until you meet with the point.

Once you reach the point, move down to the axis, the value at which you intersect the axis is the x-value.

We can see that the point is on the middle of the x-values:

x = 70 and x = 80

Then the x-value of the point is x = 75

This means that the correct option is 75

Answer:

x=-3 is not a solution

Step-by-step explanation:

well, lets plug it and and see!

6(-3)-19=3(-3)-10

-18-19=-9-10

-37=-19

-37 DOES NOT equal -19.

so x=-3 is not a solution

hope this helped! :)

Answer:

A) y=2x-3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(9-5)/(6-4)

m=4/2

m=2

y-y1=m(x-x1)

y-5=2(x-4)

y=2x-8+5

y=2x-3

Answer:

5, -28, 10.4, -.875, 0, 8003

Step-by-step explanation:

Answer:

The correct answer should be the first option.

Step-by-step explanation:

Answer:

First option. The graphs domain is -∞<x<∞ and its range is -5 ≤ y < ∞

Step-by-step explanation:

I graphed this function

Domain: x ∈ R

Range: y ∈ [-5, + ∞

Minimum (1, -5)

Verticle intercept (0, -4)

Given:

i) 3, -5, -2, 1

ii) -1, -8, -7, -2

iii) -2, -4, 0, 2

To find:

increasing order of the given numbers.

Solution:

Increasing order: We need to start from the smallest number, then write larger number and end with the largest number.

We know that all negative numbers are less than the positive numbers and larger negative value is always the smaller one.

For example: -3 is less than -1.

i) We have,

3, -5, -2, 1

So, the increasing order of these number is -5, -3, -2, 1.

ii) We have,

-1, -8, -7, -2

So, the increasing order of these number is -8, -7, -2, -1.

iii) We have,

-2, -4, 0, 2

So, the increasing order of these number is -4, -2, 0, 2.

Answer:linear

Step-by-step explanation:

Answer:

(-4,5)

Step-by-step explanation:

use elimination method to solve

x+2y=6

3x+4y=32

make the x coefficient to be equal by multiplying the x by 3

3x+6y=18

-3x+4y=32

since the signs for the z coefficient are different than you add 3x+-3x=0

6y+4y=10y

18+32=50

10y=50

y=5

if y is equal to 5 then substitute

x+(2*5)=6

x+10=6

x=-4

(-4,5)

Answer:

The answer is (3, -3)

Step-by-step explanation:

Translating it down means subtracting from the second value, or the y value. 0 - 3 = -3. You keep the x value the same.

Answer:

C(3, -3).

Step-by-step explanation:

When it is translated down, the y-coordinate changes.

Subtract 3 from the y-coordinate.

C(3, 0) becomes C(3, -3).

Answer:

1 : 5
