Andre performs a 90-degree counterclockwise rotation of polygon p and gets polygon p but he does not say what center of the rotation is

Answers

Answer 1

The center of rotation for the polygon p is shown as the red point in the attached graph below.

A plane figure spins around a point known as the center of rotation. Throughout the rotation, this point remains stationary.

The fixed point that the rotation revolves around in a figure or object with rotational symmetry is referred to as the center of rotation. As an illustration, we consider the point in the middle of a windmill where the blades start to rotate.A rotation is a transformation in which every point of a figure is turned through a predetermined angle and in a predetermined direction around a fixed point. The fixed point is referred to as the rotational center. The term "angle of rotation" refers to the rotation's amount and is expressed in degrees.

An irregular 14-sided polyhedron which has two congruent bases is as shown in the attached file.

What is a Polyhedron?

A polyhedron is a three dimensional solid shape made by joining together polygons.

For example we can consider a prism having 12-sided regular polygons as bases because then there would be 2 bases and 12 lateral sides for a total of 14 sides for the polyhedron.

Since the lateral faces are rectangles and not 12-sided polygons like the bases, the polyhedron is an irregular polyhedron.

Applying the above, we can draw an irregular 14-sided polyhedron which has two congruent bases as shown in the attached file.

Is (2,-1) a solution of 2x-y=5? Explai
how your work.

Answers

Answer:

Yes, (2, -1) is a solution.

Step-by-step explanation:

Plug in 2 for x and -1 in for y and see if it is a true statement.

2x - y = 5

2(2) - (-1) = 5

4 - (-1) = 5 Subtracting a negative number is the same as adding a positive number

4 + 1 = 5

5 = 5 Since this statement is true, (2,-1) is a solution.

Answers

(7,-4) is not a solution of the inequality y ≥ 5 - x

How to tell whether (7,-4) is a solution of y ≥ 5 - x?

The inequality expression is given as

y ≥ 5 - x

The solution is given as:

(7, -4)

This means that

(x, y) = (7, -4)

Substitute (x, y) = (7, -4) in the inequality y ≥ 5 - x

So, we have

-4 ≥ 5 - 7

Evaluate the difference

-4 ≥ -2

On the numbering system, -4 is less than -2

Hence, (7,-4) is not a solution of the inequality y ≥ 5 - x

The recommended mass of a Soccer ball is 0.43 kilogram. The actual mass is allowed
to vary by up to 20 grams.
a. Write and solve an absolute value equation to find
the minimum and maximum acceptable soccer ball
masses.
b. A soccer ball has a mass of 423 grams. The soccer
ball loses 0.016 kilogram of mass over time. Is the
mass now acceptable? Explain.

Answers

The absolute value equation is:

|M - 430g| = 20g

And the solutions are M = 410g and M = 450g

b) No, the mass is not acceptable.

How to write the absolute value equation?

We know that the recomended mass is 0.43kg, with an accepted error of 20 grams.

Where:

0.43kg = 0.43*1000g = 430g

Then the minimum mass accepted is: 430g - 20g = 410g

The maximum mass accepted is: 430g + 20g = 450g

These are the solutions, and the absolute value equation is, if M is the mass:

|M - 430g| = 20g

b) If the ball has a mass of 423g it is in the accepted range, if now it loses 0.016kg:

0.016kg = 0.016*1000g = 16g

The new mass is:

423g - 16g = 407g

This is smaller than the minimum accepted mass, then this mass is not acceptable.

Step-by-step explanation:

Randy's swimming coach kept track of his average 50-meter lap times during the first 3 weeks of training. How much greater was the percent of change from Week 1 to Week 2 than from Week 2 to Week 3? Round to the nearest tenth of a percent.

Answers

The percent of the first change is greater by 2.36%.

Time in 1st week = 28.8 sec

Time in 2nd week = 27.6 sec

Time in 3rd week = 27.1 sec

∴ Change of time from week 1 to week 2 = (28.8 - 27.6) sec

= 1.2 sec

∴ Percent of change from week 1 to week 2 = [tex]\frac{time change}{1st week time} \times 100[/tex] %

= [tex]\frac{1.2}{28.8} \times 100[/tex] %

= 4.17%

∴ Change of time from week 2 to week 3 = (27.6 - 27.1) sec

= 0.5 sec

∴ Percent of change from week 2 to week 3 = [tex]\frac{Time change}{2nd week time} \times 100[/tex] %

= [tex]\frac{0.5}{27.6} \times 100[/tex] %

= 1.81%

∴ The greater change was in the first week. The amount by which it was greater is = (4.17 - 1.81) %

= 2.36%

suppose that a function f has domain (-2,2) and range (-3,5). what is the domain of the function f(2x)?

Answers

The domain of the function f(2x) is (-1, 1).

Given that a function f has domain (-2,2) and range (-3,5).

We need to determine the domain of the function f(2x).

To determine the domain of the function f(2x), we need to consider how the original domain (-2,2) is affected by the transformation of multiplying the input by 2.

When we multiply x by 2, it stretches or compresses the function horizontally.

In this case, multiplying by 2 will stretch the original domain by a factor of 1/2.

To find the new domain, we divide the original domain endpoints by 2:

New domain = (-2/2, 2/2) = (-1, 1)

Therefore, the domain of the function f(2x) is (-1, 1).
