Find The Area Of Each Regular Polygon. Round To The Nearest Tenth.A= _ In2 ?

Answers

Answer 1

Answer:

Area of the square = 225.0 in²

Step-by-step explanation:

Given polygon is a regular polygon that means given quadrilateral has all sides equal in measure.

And a quadrilateral with all sides equal is known to be a square.

Therefore, area of a square = (Side)²

                                              = (15)²

                                              = 225

                                              ≈ 225.0 in²

Answers

Answer:

1. 90 families

2. P 500

3. 30 sits

Step-by-step explanation:

The computation is shown below:

1. The number of families belong to the poor sector is

= 150 ×60%

= 90 families

2. The new amount is

= P 2,500 × 0.20

= P 500

3. The actual sits accommodated by the passengers is

= 60 sits ×50%

= 30 sits

(b) Reflect the point (7, -9) across the x-axis:

Answers

Answer:

(-7,-9) and (7,9)

Step-by-step explanation:7,-9 so we do across the x so you need a graph for this now x goes left so we plot the coordinates in the third box 7,-9 is in the 4 box so after we plotted that you can see it reflects.Now y coordinate since the y line goes up we plot the coordinates on top of the 4 box where our original coordinates stay now it should be 7,9 the y becomes positive which is 9.

This is not a web answer i answered myself took me some time!

This means that the slope of the tangent line at x = 4 is equal to 63.

What are some rules of exponents?

Some common rules of exponents are

xᵃ×xᵇ = xᵃ⁺ᵇ.

xᵃ/xᵇ = xᵃ⁻ᵇ.

Addition and subtraction of exponents are only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.

We also know that a multiplied by a 'n' number of times can be written

as aⁿ.

Now,  2 to the power of 6 in exponent form is 2⁶ which states 2 is multiplied by 2, 6 times.

Therefore, From the given options the expression that is equivalent to

2⁶ is 2x2x2x2x2x2.
