Answer:

500000

Step-by-step explanation:

We need to find the value of the given expression :

[tex]5^{\dfrac{5}{2}}\times 20^{\dfrac{3}{2}}\div 10^{-2}[/tex]

We can do it as per BODMAS rule.

[tex]5^{\dfrac{5}{2}}\times (\dfrac{20^{\dfrac{3}{2}}}{10^{-2}})\\\\=5^{\dfrac{5}{2}}\times {20^{\dfrac{3}{2}}}\times {10^{2}}\\\\=5^{\dfrac{5}{2}}\times {20^{\dfrac{3}{2}}}\times 100\\\\=5^{\dfrac{5}{2}}\times {(5\times 4)^{\dfrac{3}{2}}}\times 100\\\\=5^{\dfrac{5}{2}}\times {(5^{\dfrac{3}{2}})\times (4)^{\dfrac{3}{2}}}\times 100\\\\=5^{(\dfrac{5}{2}+\dfrac{3}{2})}\times 2^2^{\dfrac{3}{2}}\times 100\\\\=5^4\times 2^3\times 100\\\\=625\times 8\times 100\\\\=500000[/tex]

So, the required answer is 500000.

Step-by-step explanation:

Label the points from A-F. I attached an image of how I labeled the points.

Notice that there are similar triangles here:

Set up proportions to find the values of x, y, and z.

Let's make this problem simpler by incorporating only 2 variables instead of 3.  Let's say that the total distance between the two poles is distance d. Instead of z, let's call it d - y.

Substitute known values or variables into the proportions.

Cross-multiply and simplify Equation I.

Cross-multiply and simplify Equation II.

We now have two equations that are equal to dx, so we can set them equal to each other.

Add 6y to both sides of the equation.

Divide both sides of the equation by 6.

We can substitute this value of d back into either Equation I or II. I am going to substitute d into Equation II.

Cross-multiply and simplify the equation.

Divide y from both sides of the equation.

Divide both sides of the equation by 3.

Explanation:

In a parallelogram, there are only two sizes of angle - two are acute and two are obtuse.

Opposite angles are equal .

Consecutive angles are supplementary because they are co-interior angle on parallel lines.

An additional solution to the one given by Alan P is using the fact that the sum of the interior angles of a parallelogram is 360°.

Let one angle be  

x

The size of the other angle is given by

x

−

x

+

(

=

x

x

x

=

°

The obtuse angles are each  

180

−

21

=

159

°

The other option where the given angle is the opposite angle is described is well explained by Alan P.

Step-by-step explanation:

The interior angles of the parallelogram are 21° and 159° respectively.

What is parallelogram?

A parallelogram is defined as a quadrilateral in which both pairs of opposite sides are parallel and equal.

In a parallelogram opposite interior angles are equal and the angles on the same side of the traversal are supplementary (i.e) 180°

For the given situation,

The measure of one interior angle be [tex]x[/tex] and

Another angle was given as [tex]9x-30[/tex]°  

⇒[tex]x+9x-30[/tex]°[tex]=180[/tex]°

⇒[tex]10x=180[/tex]°[tex]+30[/tex]°

⇒[tex]10x=210[/tex]°

On dividing [tex]10[/tex] on both sides,

⇒[tex]\frac{10x}{10}=\frac{210}{10}[/tex]

⇒[tex]x=21[/tex]°

So, another angle is [tex]9x-30[/tex] = [tex]9[/tex]×[tex]21-30[/tex]

⇒[tex]189-30[/tex]

⇒[tex]159[/tex]°

Hence we can conclude that the interior angles of the parallelogram are 21° and 159°.

Answer:

B. f(x) = -x + 2

Step-by-step explanation:

First, you find the point on the y-axis which is (0,2) in this problem.

This will be your b in y = mx+ b

Then, you'll find how many blocks you are moving or rise over run. Which is -1/1 or -1.

This will be your m in y = mx + b

But we don't write the 1 so it will just be -x

Now add all your numbers in the standered form (y = mx + b) to get y = -x + 2 or f(x) = -x + 2
