Answer:

YZ is located at Y (0, 1) and Z (-2, 1) and is one-third the size of Y'Z'.

Step-by-step explanation:

Since Y'Z' was dilated from the origin at a scale factor of 3, you can divide its X and Y coordinates by 3 to find the coordinates of YZ.

The statement fourth "segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime" is correct.

The transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller. The image created by this transformation is identical to the original shape.

The question is incomplete.

The complete question is:

Segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3). segment YZ was dilated at a scale factor of 3 from the origin. Which statement describes the pre-image?

As we know, in the dilation image of the two-dimensional figure can be larger or smaller depending on the dilation factor.

We have:
segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3).

After dilation:

Y (0, 1) and Z (−2, 1)

Thus, the statement fourth "segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime" is correct.

Answer:

48.9 and 50.5 are rejected.

Step-by-step explanation:

Since the standard deviation shows the spread of the values of the voltages, we need to find the mean of the values and use the standard deviation to find the minimum and maximum voltage allowed.

So mean μ = Σx/N where x = individual values of voltage and N = number of values = 10

So, μ = Σx/N

= (49.3 + 50.1 + 48.9 + 49.2 + 49.7 + 50.5 + 49.9 + 49.3 + 49.8 + 50.2)/10

= 496.9/10

= 49.69

≅ 49.7 V

So, the acceptable values of voltage are in the range μ ± σ where σ = standard deviation = 0.50 V.

So, the acceptable values of voltage are in the range 49.7 ± 0.50 V

So, minimum value = 49.7 V - 0.50 V = 49.2 V

and maximum value = 49.7 V + 0.50 V = 50.2 V

So any voltage outside the range 49.2 V ≤ x ≤ 50.2 V is rejected.

There are two values outside this range which are 48.9 and 50.5. So these two values are rejected.

Answer:

X = 0 or X = -4

Step-by-step explanation:

4X(X + 4) = 0​

4 = 0 or X = 0 or X + 4 = 0

Since 4 = 0 is false, we eliminate that equation.

X = 0 or X + 4 = 0

X = 0 or X = -4

Answer

The length of the hypotenuse is 35 feet.

Explanation

This is the formula to find the hypotenuse.

[tex]l^{2} + l^{2} = h^{2}[/tex]

One leg is 21 feet. The other is 28 feet. Now insert those into the formula.

[tex]21^{2} + 28^{2} = h^{2}[/tex]

[tex]h^{2}=1225[/tex]

Now to find what h is you should find the square root of 1225.

[tex]\sqrt{1225} =35[/tex]

So the length of the hypotenuse is 35 feet.

step by step Explanation:

[tex]f(x)=2x^2+6x-4\\[/tex]

Find f(-5) by substituting x = -5 in the equation.

[tex]f(-5)=2(-5)^2+6(-5)-4\\f(-5)=2(25)-30-4\\f(-5)=50-34\\f(-5)=16[/tex]

Therefore, the answer is f(-5) = 16

Answer:

f(-5)=126

Step-by-step explanation:

what you would do first is plug -5 in for x which would give you the equation of f(-5)= 2(-5)^2 + 6(-5) -4

then you multiply the negative 5 and you will get

f(-5)= -10^2 + 30 -4

remove that square by multiplying -10 by -10 and you will get

f(-5)= 100 + 30 -4

combine like terms and you will get

f(-5)=126

Answer:

3.36 quarts of paint

Step-by-step explanation:

In this question, we're trying to find how much paint she will need to cover the night stand.

First, we need to find the area.

Solve for the area (rectangle = l * w):

42 · 28 = 1176

Now, we know that 1 quart of paint covers 350 square inches.

To find how much paint she needs, divide 1176 by 350:

1176/350 = 3.36

This means that she needs 3.36 quarts of paint to cover her whole nightstand.
