The quantity is 25/8.

Given in words to evaluate the expression, 2 squared times 2 to the power of negative 5 and over 5 to the power of negative two.

Square of a number denotes a number to the power of 2.

The expression is :   [tex]\frac{2^2\times2^{-5}}{5^{-2}}[/tex]

We have to use the law of exponents here:

   [tex]a^m \times a^n = a^{m+n}[/tex]

and

  [tex]\frac{a^m}{a^n} = a^{m-n}[/tex]

In the above cases, the bases should be same for the two numbers.

So   [tex]2^2 \times 2^{-5} = 2^{-3}[/tex]

Also, negative exponents like  [tex]a^{-m} = \frac{1}{a^m}[/tex].

Therefore,     [tex]\frac{2^{-3}}{5^{-2}} = \frac{5^2}{2^3} =\bold{ \frac{25}{8} }[/tex]

Answer: -13w - 7

Step-by-step explanation:

-6w + (-8) + 1 + (-7w)

Combine the like terms

-8 + 1 = -7

-6w + (-7) + (-7w)

-6w + (-7w) = -13w

-13w + (-7)

However, because adding a negative number is the same as subtracting the number as a positive, you can just make it -13w - 7

Answer:

y = -9/8x +7

Step-by-step explanation:

We know two points on the line so we can find the slope

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

m = ( -2 -7)/(8 -0)

  = -9/8

We also know the y intercept which is 7

The slope intercept form of the line is

y = mx+b where m is the slope and b is the y intercept

y = -9/8x +7

Answer:

[tex]y=-\frac{9}{8}x+7[/tex]

Step-by-step explanation:

Slope-intercept form is y=mx+b

Use the formula for slope: m=(y2-y1)/(x2-x1)

m=(-2-7)/(8-0)

m=-9/8

The graph shows that b, the y-intercept, is at (0,7)

Therefore, the final equation is [tex]y=-\frac{9}{8}x+7[/tex]

Answer:

y=5x+11

Step-by-step explanation:

using point-slope equation, we substitute.

parallel lines have the same slope.

y-y¹=m(x-x¹)

y-6=5(x+1)

y-6=5x+5

y=5x+11

Answer: rise is 4 and run is 5

Step-by-step explanation:

Answer:

down below

Step-by-step explanation:

To find the rise over run, you need to pick a point that intersects one of the axises. Then, you need to find a point that intersects the other axis. Third, you find the first point and begin moving up or down until you reach the height of the other point. From there, you count along that height line until you reach the second point. The number from counting on the y axis is the rise and the number from counting on the x axis is the run. So, you take the rise and put it over the run.

Hope this helps! :)

The m variable is the slope of the line and controls its 'steepness'. A positive value has the slope going up to the right. A negative slope goes down to the right. The b variable is the y intercept - the point where the line crosses the y axis.

example 1                                                    

y = mx + b

m = slope b = y-intercept

y = 3x - 1

m = 3 and b = -1

example 2

y = b + mx

b = y-intercept m = slope

y = 5 - 1/2x

m =- 1/2 and b = 5

The reliability of a two-component product if the components are in parallel, with individual reliabilities of 0.95, and 0.80 is 0.99. The answer is option b.

The probability that a specific object will carry out its intended function for a specific amount of time under a specific set of circumstances without experiencing any failures is known as reliability.

The reliability definition is based on four criteria: function, fulfillment likelihood, duration, and environment. Maintainability and reliability are related because when a machine or product malfunctions, there may be a way to get it back into working order.

When we use the phrase "talking reliability-smart," we mean that any of the aspects that shape the device in parallel can be considered. This does not necessarily imply that they are physically parallel (in all circumstances), as parallel capacitors have a certain behavior in the circuit and may malfunction if one of them fails.

Parallel forms reliability is a measure of reliability obtained by giving the same set of people different versions of an assessment tool (each version must contain items that probe the same construct, talent, knowledge base, etc.

The complete question is given below:-

Answer:

Step-by-step explanation:

I think x=-2

The value of x is 11. Then the length of the line segment PR, PQ, and QR will be 52, 30, and 22, respectively.

An axis is a term used to describe a line on which points are located, particularly if that line is connected to a triangle or other geometric shape. Since two factors determine a line, two points are transparently collinear. If the points are in a line, then the points are collinear points.

Let A, B, and C be the collinear points. Then the condition of the collinear will be

AB + BC = AC

PQ = 2x + 8, QR = x + 11, and PR = 5x - 3.​ From the figure, the points P, Q, and R are the collinear points. Then we have

PQ + QR = PR

2x + 8 + x + 11 = 5x - 3

3x + 19 = 5x - 3

22 = 2x

x = 11

Then the line segment PR, PQ, and QR will be

PQ = 2 × 11 + 8

PQ = 22 + 8

PQ = 30

QR = 11 + 11

QR = 22

PR = 5 × 11 - 3

PR = 55 - 3

PR = 52

The value of x is 11. Then the length of the line segment PR, PQ, and QR will be 52, 30, and 22, respectively.

Answer:

12.88

Step-by-step explanation:

Answer:

its 12.88

Step-by-step explanation:

when 1/2 divided by (-8 / 12), it is equivalent to ( -3 /4)

Let an expression be 'x'

Given that, an expression must exist that is equivalent to -3/4 when divided by (-8/12).

This leads us to the conclusion that = x / (-8 / 12) = -3 / 4

It is equivalent to = x * (- 12 / 8) = -3 / 4

We get = x * (- 12 / 8) * (- 8 / 12) = -3 / 4 * (-8 / 12) by multiplying (- 8 / 12) on both sides.

We get = x = - 3/ 4 * (-8 / 12) by canceling like numbers.

x = 24 / 48

x = 1 / 2

Therefore, 1/2 divided by (-8 / 12) equals (-3 / 4).
