what is the perimeter of this polygon with coordinates (2,4), (3,-2), (-2,-3), and (-1,2)

Answer:

A

Step-by-step explanation:

Table 1 shows the linear relationship between the two variables.

A linear relationship is one in which two variables have a direct connection, which means if the value of x is changed, y must also change in the same proportion.

According to the given question.

We have some tables. Which represents the relationship between the two variables x and y.

Since,

If x is linearly related to y then the slope will same for every points.

For the

Table 1.

For the points (9, 13) and (14, 16)

\(slope = \frac{16-13}{14-9}\)

\(\implies slope = \frac{3}{5}\)

For the points (14, 16) and (19, 19)

\(slope = \frac{19-16}{19-14} =\frac{3}{5}\)

So we can see that the slope is same for each pair of points.

Hence, table 1 shows the linear relationship between the two variables.

Table 2:

For the points (-4, 2) and (2, 10)

\(slope = \frac{10-2}{2+4} =\frac{8}{6} =\frac{4}{3}\)

For the points (8, 50) and (2, 10)

\(slope = \frac{10-50}{2-8} =\frac{-40}{-6} =\frac{20}{3}\)

Since, the slope are not same. Therefore, table 2 doesn't shows the linear relationship between the two variables.

For table 3

Since the slope is changing therefore, table 3 doesn't shows the linear relationship between the two variables.

Answer: y=-2x+7

Step-by-step explanation:

If all you are asking for is to solve for y, then that means you have to isolate this variable. You can do so by simply subtracting 2x from both sides of the equation. This leaves you with y=-2x+7. Hope this helps!

Answer:

Area of rectangle OABC = 18 units²

Step-by-step explanation:

From the graph attached,

Vertices of the rectangle are O(0, 0), C(3, 0) and A(0, 6).

Length of side AO = 6 units

Length of side OC = 3 units

Area of the rectangle = Length × Width

                                    = OC × AO

                                    = 3 × 6

                                    = 18 square units

The parametric equations for an object moving clockwise along the ellipse are x =  3 cos((2π/3) t) and y = 5 sin((2π/3) t)

Given: the equation of an ellipse x²/9 + y²/25 = 1

Beginning at (0,5) and requiring 3 seconds

The parametric equations representing an ellipse x²/a² + y²/b² = 1  are

x = a cos(t) and y = b sin(t)

where t is the parameter with values between [0, 2π]

If t represents time. Then, if a lap around the ellipse is completed in T seconds we have,

x = a cos((2π/T) t)

y = b sin((2π/T) t)

where 2π/T is the period of the motion.

Combining these results, therefore, we have the parametric equations:

x =  3 cos((2π/3) t)

y = 5 sin((2π/3) t)

The growth rate of the population, given the initial population and the population after 10 years is 12. 5 % every 10 years.

To find the percent change or growth rate of a quantity between two different values, you can use the formula:

Percent change = ( new value - old value ) / old value x 100%

The new value would be the population of the village after 10 years which is 450 people.

The old value is the initial population of the village which is 400

The growth rate of the population is:
= ( 450 - 400 ) / 400 x 100 %

= 12. 5 %

The growth rate for the village is therefore 12. 5 % every ten years.

Answer:

4.28%

Step-by-step explanation:

We Know

Last year you earned $72,400

This year you earned $75,500

What was the rate of change in your earnings since last year?

We Take

(75,500 ÷ 72,400) x 100 ≈ 104.28%

Then We Take

104.28 - 100 = 4.28%

So, the earning increased by about 4.28%.

Step-by-step explanation:

given

\( \frac{7056}{x} = 42 \\ \\ 42x = 7056 \\ x = \frac{7056}{42} \\ = 168\)

also given

\( \frac{y}{112} = 8 \\ y = 8(112) \\ = 896\)

therefore

\( \frac{x}{y} = \frac{168}{896} \\ = \frac{3}{16} \)

Answer:

  192.7 cm³

Step-by-step explanation:

You want the volume of a regular pentagonal prism with a base side length of 4 cm and a height of 7 cm.

The area of a regular n-gon is given by the formula ...

  A = n·s²/(4·tan(180°/n))

For n=5 and s=4 cm, the area of the prism base is ...

  A = 5·(4 cm)²/(4·tan(36°)) = 20/tan(36°) cm² ≈ 27.528 cm²

The volume of a prism is ...

  V = Bh

where B is the base area, and h is the height. Here, we have h=7 cm, so the volume is ...

  V = (27.528 cm²)(7 cm) ≈ 192.7 cm³

The volume of the interior of the box is about 192.7 cm³.
