E = exterior angle = 60 degrees

n = number of sides of the regular polygon

n = 360/E

n = 360/60

n = 6

The regular polygon has 6 sides.

I suppose it's going to look like this, you just need to continue the graph for other figure numbers and numbers of circles

y=7(10)= 70

Step-by-step explanation:

Answer:

X     Y

3     21

8     56

10    70

Step-by-step explanation:

Find Y by plugging in each X value to the given function.

Encuentre Y reemplazando cada valor de X en la función dada.

When x = 3 : y = 7 * 3 = 21

Cuando x = 3 : y = 7 * 3 = 21

When x = 8 : y = 7 * 8 = 56

Cuando x = 8 : y = 7 * 8 = 56

When x = 10 : y = 7 * 10 = 70

Cuando x = 10 : y = 7 * 10 = 70

The area of the planned school garden have dimensions of g + 4 and g + 10 respectively.

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the area of the planned school garden as:

A = g² + 14g + 40

A = g² + 10g + 4g + 40 = g(g + 10) + 4(g + 10)

A = (g + 4)(g + 10)

The linear equations of the candles are y = 0.5x + 8 and y = 0.4x + 8. And both relationships are the function.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A candle burns down at the rate of 0.5 inches per hour.

The original height of the candle was 8 inches.

Let y be the height of the candle and x be the number of hours.

Then the linear equation will be given as

[tex]\rm y = mx + c[/tex]

where m is the rate and c is the initial value. Then the linear equation of the candle will be

y = -0.5 x + 8

The function is a linear function.

If the value of m is replaced by 0.4. Then the linear equation will be

y = 0.4x + 8

And this will also be a linear function.

Answer:

the dryer costs $450

step-by-step explanation:

w + d = 831

w = d-69 (they told us we will have to take $69 from the cost of the dryer to determine the cost of the washer)

(d-69) + d = 831

Let's combine like terms

2d - 69 = 831

add 69 to both sides to solve for d

2d = 900

divide both sides by 2 to solve for d

d = 450; the dryer costs $450

Answer:

Step-by-step explanation:

The equation of a circle:

(a, b) - the center of a circle

r - the radius of a circle

x² - 8x + 16 + y² + 10y + 25 = 81

(x² - 2(x)(4) + 4²) + (y² + 2(y)(5) + 5²) = 81

use: (a - b)² = a² - 2ab + b² and (a + b)² = a² - 2ab + b²

(x - 4)² + (y + 5)² = 9²

Therefore

the radius: r = 9

the center: (4, -5)

The radius is 9 and the center of the circle  (4, -5)

A circle's center is a point throughout the circle that is equally spaced from every other point on the circumference. The line of refraction symmetry is formed by all lines that traverse the circle. Additionally, every angle possesses rotational symmetry surrounding the centre.

The equation of a circle:

(x - a)² + (y - b)² = r²

The center of a circle will be (a, b)

The radius of a circle will be r

x² - 8x + 16 + y² + 10y + 25 = 81

Solving the above equation on the basis of the Equation of a circle.

(x² - 2(x)(4) + 4²) + (y² + 2(y)(5) + 5²) = 81

Using the identity in the above-given equation.

(a - b)² = a² - 2ab + b² and (a + b)² = a² - 2ab + b²

(x - 4)² + (y + 5)² = 9²

The center of the circle will be at coordinates 4 and 5. And the radius of the circle derived is 9.

The area of the trapezoidal tarp in the hotel is 47.3 square inches

The area of a trapezoid is calculated using:

Area = 0.5 * (Sum of parallel sides) * Height

From the complete question, the parallel sides are:

10 ft and 12 ft

So, we have:

Area = 0.5 * (10 +  12) * h

Evaluate

Area = 11 * h

The height (h) is calculated using the following cosine function

cos(120 - 90) = h/5

This gives

cos(30) = h/5

Make h the subject

h = 5cos(30)

Evaluate

h = 4.3

So, we have:

Area = 11 * 4.3

Evaluate

Area = 47.3

Hence, the area of the trapezoid is 47.3 square inches
