Step-by-step explanation:

Answer:

1.) up

2.) (-2,-5)

3.) x = -2

4.) (-2,-5)

5.) y = -5

6.) -∞ < x < ∞

7.) -5 < y < ∞

8.) (0,0)

9.) (0,0) and (-4,0)

10.) two solutions

Step-by-step explanation:

1.) because the parabola opens upward and the vertex is down

2.) the lowest point of the parabola is (-2,-5)

3.) If a line was drawn through the point x = -2, the two halves of the parabola would look symmetrical ( the same on both sides).

4.) The minimum point on the graph is ( -2,-5), because that is the lowest point on this upward parabola, and we can not determine the maximum.

5.) The minimum value of y is y = -5, because that is the lowest value of y on this graph, and we can not determine the maximum.

6.) Because the arms of the parabola continue traveling through negative infinity and positive infinity on the x-axis, the domain is -∞ < x < ∞.

7.) The arms of the parabola go from y = -5 to infinity, so the range of the parabola is -5 < y < ∞.

8.) The parabola first crosses the y-axis at the point (0,0)

9.) The parabola first crosses the x-axis at the points (0,0) and (-4,0)

10,) The solution to the parabola is the variable x. The solutions (x intercepts) of the parabola are x = 0 and x = -4.

Answer:

Step-by-step explanation:

The expression under the radical can be written in vertex form as ...

  x^2 -12x +32 = (x -6)^2 -4

The function will be symmetrical about x=6. The minimum is at x=6 where we have ...

  F(6) = ∛(-4)

The maximum is at the end of the interval farthest from the vertex, so is ...

  F(10) = ∛((10 -6)² -4) = ∛12

The minimum is -∛4 ≈ -1.587; the maximum is ∛12 ≈ 2.289.

Answer:

C. 30

Step-by-step explanation:

2x = 60

x = 30

Also because the right angle of a triangle which is the angle where (2x) is at is equal to 90 degrees always, so since one of the angles is 60 the other will be 30 because the three angles of a triangle add up to 180 degrees:

90 + 60 = 150

180 - 150 = 30

Step-by-step explanation:

Exterior angles thm:

m<1 = 137

Answer:

20 - 6x = 4x - 15

35 - 6x = 4x

35 = 2x

x = 15.5

The solution to the equation 20 - 6x = 4x -15 is x = 3.5.

To solve the equation 20 - 6x = 4x - 15,

20 - 6x = 4x - 15

To isolate the variable terms on one side,  add 6x to both sides:

20 - 6x + 6x = 4x - 15 + 6x

20 = 10x - 15

Next, add 15 to both sides to further isolate the variable term:

20 + 15 = 10x - 15 + 15

35 = 10x

Finally, divide both sides by 10 to solve for x:

35/10 = 10x/10

3.5 = x

Therefore, the solution to the equation is x = 3.5.

Answer:

 46 yd

Step-by-step explanation:

The sum of horizontal lengths across the top is 8+6 = 14 yd. The length across the bottom is the same, so the total of horizontal lengths is

  14 yd +14 yd = 28 yd

The sum of vertical lengths at the right is the same as the sum of vertical lengths at the left, 9 yd, so the total of vertical lengths is ...

  9 yd + 9 yd = 18 yd

The total of all lengths around the perimeter of the figure is ...

You can use the formula for margin of error and the fact that the point estimates of both the samples are same to calculate the ratio of margin of errors of both the samples.

The margin of error from the smaller sample will be about double of the margin of error from the larger sample.

[tex]MOE_1 = 2 \times MOE_2[/tex]

Let the level of significance be [tex]\alpha[/tex] and the standard deviation of the population be [tex]\sigma[/tex] and the sample size be n, then we have:

[tex]\text{MOE(Margin of Error)} = Z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}[/tex]

For first sample :

[tex]\text{Sample size} = n_1 = 1000\\\\MOE_1 = Z_{\alpha/2}\dfrac{\sigma}{\sqrt{1000}}[/tex]

For second sample :
[tex]\text{Sample size} = n_1 = 1000\\\\MOE_2 = Z_{\alpha/2}\dfrac{\sigma}{\sqrt{4000}}[/tex]

(since it was given that they have same point estimates, so same standard deviation)

Their ratios are given by

[tex]\dfrac{MOE_2}{MOE_1} = \dfrac{Z_{\alpha/2}\dfrac{\sigma}{\sqrt{4000}}}{Z_{\alpha/2}\dfrac{\sigma}{\sqrt{1000}}} = \sqrt{\dfrac{1000}{4000}} = \dfrac{1}{2}\\\\\\MOE_1 = 2 \times MOE_2[/tex]

Thus,

The margin of error from the smaller sample will be about double of the margin of error from the larger sample.[tex]MOE_1 = 2 \times MOE_2[/tex]

Answer:

  x = {2π/3, 4π/3}

Step-by-step explanation:

The equation can be factored as ...

  (cos(x) +3)(2cos(x) +1) = 0

The solutions are the values of x where the factors are zero.

  cos(x) +3 = 0

  cos(x) = -3 . . . . . . no real solution

__

  2cos(x) +1 = 0

  cos(x) = -1/2

  x = arccos(-1/2) = 2π/3

The other solution in the desired interval is ...

  x = 2π -(2π/3) = 4π/3

The solutions are x∈ {2π/3, 4π/3}.

The measure of other supplementary angle where one angle is 100° is 80°

In the above question, it is given that two angles are supplementary angles and,

Two angles are said to be supplementary angles if their sum is 180 degrees.

We have,

The measure of one angle is = 100°

Let the angle which needs to be find as ∠x

That means, we need to find the measure of ∠x

So, according to the supplementary angles property,

100° + ∠x = 180°

∠x = 180 - 100

∠x  = 80°

Hence,  the measure of other supplementary angle where one angle is 100° is 80°

Answer:

The copy machine makes 32 copies per minute.

Step-by-step explanation:

Given that a copy machine makes 136 copies in 4 minutes and 15 seconds, to determine how many copies does it make per minute, the following calculation must be performed:

15 seconds = 0.25 minutes

136 / 4.25 = X

32 = X

Therefore, the copy machine makes 32 copies per minute.
