Which figures are polygons? Figure A has 6 sides all made of line segments. figure b is a regular hexagon. it has 6 sides made all of segments. Figure c is shaped iike a long semicircle. the bottom is a segment. The top part is curved. Figure D has 7 sides which are all segments.

Answers

Answer 1

A polygon is a closed figure made by joining line segments, where each line segment intersect exactry two other line segments.

A polygon is said to be a regular polygon if the sides are all of the same length.

Thus, the figures that are polygon are:

Figure A which has 6 sides all made of line segments.

Figure B which is a regular hexagon, having 6 sides made all of segments.

Figure D has 7 sides which are all segments.

Given that (-4,5) is on the graph of f(x), find the corresponding point for the function f(2x)

Answers

Answer:

the correct answer is (-2,5)

Step-by-step explanation:

you multiply 1/2 by -4 to get the x value

To find the corresponding point on the function f(2x) given a point on the original function f(x), simply multiply the x-coordinate by 2. In this case, the corresponding point is (-8,5).

Given: Point (-4,5) is on the graph of f(x).

To find: Corresponding point for the function f(2x).

Solution:

When x = -4, 2x = 2*(-4) = -8.So, the corresponding point for f(2x) would be (-8,5).

Rita bought a table on sale for $278.80 . this price was 66% less than the original price. what was the original price?

if it was 66% less then the original, then u paid 34%

34% of the original price = 278.80
0.34x = 278.80
x = 278.80 / 0.34
x = 820 <== original price was $ 820

The distance you travel while hiking is a function of how fast you hike and how long you hike at this rate. You usually maintain a speed of three miles per hour while hiking. Write a statement that describes how the distance that you travel is determined. Then identify the independent and dependent variables of this function.

Answers

If hours is represented as h, your distance is therefore 3*h (due to that for every hour, you walk 3 miles. For example, in one hour you'd walk 3 miles, in 2 hours you'd walk 3+3=3*2=6 miles,etc.). If distance is represented by d, we get 3*h=d. Since you have to figure out the distance from the equation (that's the purpose of it!), the distance is the dependent variable. In addition, since you can't have 2 separate variables in one equation, h is the independent variable due to that you have to put a number for h in to figure out the distance

Find the Perimeter of the polygon with the vertices X(-1,3), Y(3,0), and Z(-1,-2). Round the answer to the nearest hundredth

Answers

The perimeter is 14.47

Since you have 3 vertices, the polygon you have is a triangle. The sides of the triangle will be XY, XZ, and YZ. Just use the pythagorean theorem to calculate the length of each side and then add the lengths together for the result. Side XY = sqrt( (-1-3)^2 + (3-0)^2) = sqrt(16+9) = sqrt(25) = 5 Side XZ = sqrt ( (-1-(-1))^2 + (3-(-2))^2) = sqrt(0+25) = sqrt(25) = 5 Side YZ = sqrt( (3-(-1))^2 + (0-(-2))^2) = sqrt(16 + 4) = sqrt(20) = 4.47 Now add the length of each side together 5 + 5 + 4.47 = 14.47

Daniel income tax rate is 15% if he made 32,000 this year what will his pay be in taxes this year

Answers

Final answer:

Daniel will pay $4,800 in taxes for the year by applying a 15% tax rate to his $32,000 income.

Explanation:

To calculate the amount of income tax Daniel will pay on his $32,000 income, we will apply the 15% tax rate that corresponds to the income bracket provided in the reference material. Here's how the calculation is done:

First, identify the total income: $32,000.Next, multiply the total income by the tax rate: $32,000 * 15% (or 0.15).The calculation will be: $32,000 * 0.15 = $4,800.

Therefore, Daniel will pay $4,800 in taxes for the year.

Answers

The left bottom sector will be the next shape that is going to be shaded.

Given that,
Five circles in a row. Each circle is divided into 4 equal-sized sectors.
In the first circle, the top left sector is shaded.
In the second circle, the bottom left sector is shaded.
In the third circle, the bottom right sector is shaded.
In the fourth circle, the top right sector is shaded.
In the fifth circle, t the bottom right sectoris shaded.
Which shape was most likely her conjecture for the next shape is to be determined.

Fraction is defined as the number of compositions that constitutes the Whole.

Here,
Let assign a number of shading to the various sector of the circle,
1 = the top left sector
2 = the bottom left sector
3 = the bottom right sector
4 = the bottom right sector

Now,
Series of shading the sector of a circle,
1, 2, 3, 4, 3, 2,1

The sum of 16 and a number x is equal to 20

Answers

" the sum " means add

16 + x = 20 <= ur equation

The sum of 16 and 4 is equal to 20.
This is how I know:
20-16=4
How do I know this?
Sum means to add. To get the sum of something that equals another number, you must see what number adds up with 16 to get 20. So, this means that 16+4=20.

The measure of one of the acute angles in a right triangle is 59°. what is the measure of the other acute angle?

Answers

The answer is: 31° .
________________________________

59 + 90 + x = 180

59 + 90 = 149 ;

x + 149 = 180 ;

Subtract 149 from each side of the equation:

x + 149 - 149 = 180 - 149 = 31 .

The answer is: 31° .

in a right triangle, the acute angles will add to 90 degrees

that is because one of the angles is 90 and the sum of all the angles is 180
so if x and y are the acute angles and z is the right angle then
x+y+z=180, subsitutuing 90 for z
x+y+90=180
minus 90
x+y=90

so if one is 59 degrees then
59+y=90
minus 59 from both sides
y=31

the other acute angle is 31 degrees

When 75% of a number is added to 6, the result is 3 more than the number. find the number?

Answers

hello :
let : x this the number
(75/100)x +6 = x+3

(3/4)x - x = 3 -6
(-1/4)x = -3
x = 12

To find the number in question, an equation is set up and solved, resulting in the number 12, which satisfies the given conditions where 75% of the number added to 6 equals 3 more than the number itself.

The question asks to find a number such that when 75% of it is added to 6, the result is 3 more than the number itself. To find this number, we can set up an equation: Let the number be represented by x. So, we have 0.75x + 6 = x + 3. To solve for x, we subtract 0.75x from both sides of the equation to get 6 = 0.25x + 3. Next, we subtract 3 from both sides to get 3 = 0.25x. Finally, dividing both sides by 0.25 gives us x = 12. Therefore, the number we are looking for is 12

Let the age of Jen 2 years later be x,

age of jack two years later = 2x
total age of jack and jen now = 2x + x - 2 - 2

3x = 70
x = 70/3

age of jen now = x - 2

A rectangle is twice twice as long as it is wide and has the same perimeter as a square whose area is 9 square feet feet larger than that of the rectangle. what are the dimensions of both the rectangle and the square?

Answers

The dimension of rectangle : 6 and 12 units

square= 9 units

What is Perimeter ?

Perimeter is the distance around the edge of a shape.

Given:

let the width of rectangle be x.

length= 2x

let the side of square is y units.

Perimeter of rectangle = Perimeter of square

and, Area of square= Area of rectangle + 9

First, Perimeter of square= 4* side

= 4y units

Perimeter of rectangle,

=2(l+b)

=2(2x+x)

=6x units

Since, Perimeter of rectangle = Perimeter of square

6x=4y

3x=2y

Now, Area of square= Area of rectangle +9

y²= x*2x+9

y²= 2x²+9

y²= 2(2y/3)²+9

y²= 8y²/9+9

1/9 y²= 9

y²=81

y=±9

So, x=2y/3= 2*9/3

x= 6

Hence, dimension of rectangle is 6 and 12.

dimension of square is 9 units.
