Answer:

$7,719.33

Step-by-step explanation:

$24,500 x 0.06 = $1,470

($24,500 + $1,470) x 0.06 = $1,558.20

($24,500 + $1,558.20) x 0.06 = $1,563.49

($24,500 + $1,563.49) x 0.06 = $1,563.81

($24,500 + $1,563.81) x 0.06 = $1,563.83

$1,470 + $1,558.20 + $1,563.49 + $1,563.81 + $1,563.83 = $7,719.33

Answer:

-10

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-3-7)/(0-(-1))

m=-10/(0+1)

m=-10/1

m=-10

Answer:

The slope is -10.

Step-by-step explanation:

Goal

Given

Step 1

[tex] \large \boxed{m = \frac{y_2-y_1}{x_2-x_1} }[/tex]

From the given coordinate points, substitute the values in the formula.

[tex]m = \frac{7 - ( - 3)}{ - 1 - 0} \\ m = \frac{7 + 3}{ - 1} \longrightarrow \frac{10}{ -1} \\ m = - 10[/tex]

Therefore, the value of m or slope is -10.

Answer: y = 3

Step-by-step explanation:  

So, we must find an equation of a line that passes through these two points such that we find the slope first as,  

m = (3-3) / (2-(-1)) = 0 / 3 = 0. Then we bring up the point-slope form of an equation to find the line such that  

y - y1 = m(x - x1). Next,  

y - 3 = 0(x - (-1))

y - 3 = 0..............Then add 3 such that the equation of a line is

Answer:

D - 33

Step-by-step explanation:

From 5 to 6, the number is increasing by 1. Then from 6 to 8, it increases by 2. From 8 to 11 it increases by 3. This pattern continues throughout the entire sequence. Since between 20 and 26, it increases by 6, 26+7 should equal the number between 26 and 41. This number would be 33.

(5, 2) & (-4, -9)

Step-by-step explanation:

Use the vertex form, y = a(x − h)² + k, to determine the values of a, h, and k

(h, k) = (5, 2)

(h, k) = (-4, -9)

Answer:

200.6 degrees Celsius

We have the given number, 176.8 degrees Celsius, and we add or increase it by 23.8 degrees.

176.8 + 23.8 = 200.6

Our final answer is 200.6 degrees Celsius.

Answer:

All exterior angles will add up to 360 degrees, regardless of the number of sides.

For the sum of the interior angles, use this formula:

The sum of the interior angles = (N x 180) - 360

Where N = the number of sides

So, (40 x 180) - 360 = 6840 degrees

The measure of each interior and exterior angle of a regular 40-gon are [tex]171^\circ[/tex] and [tex]9^\circ[/tex] respectively.

Important information:

Interior angle of a regular polygon is [tex]\dfrac{(n-2)\times 180^\circ}{n}[/tex], where n is the number of sides.

A regular 40-gon has 40 sides. So, the measure of each interior angle is:

[tex]\dfrac{(40-2)\times 180^\circ}{40}=38\times 4.5^\circ[/tex]

[tex]\dfrac{(40-2)\times 180^\circ}{40}=171^\circ[/tex]

Exterior angle of a regular polygon is [tex]\dfrac{360^\circ}{n}[/tex], where n is the number of sides.

A regular 40-gon has 40 sides. So, the measure of each exterior angle is:

[tex]\dfrac{360^\circ}{40}=9^\circ[/tex]

Therefore, the measure of each interior and exterior angle of a regular 40-gon are [tex]171^\circ[/tex] and [tex]9^\circ[/tex] respectively.
