Find the area of the polygon defined by the coordinates (0, -5), (-5, 0), (-15, -20), and (-20, -15).

lapo4ka [179]

This is a rectangle... Did you draw the points?

Find
- the length of the segment going from (-5,0) to (0,-5)
- and the length of the segment from (-20,-15) to (-15,-20).

These are the length and width of the rectangle; multiply both quantities.

The width is found with the formula:
$\sqrt{x_1 - x_2)^2 + (y_1 - y_2)^2} = \sqrt{((-15) - (-20))^2 + ((-20) - (-15))^2}$
The length is $\sqrt{x_1 - x_2)^2 + (y_1 - y_2)^2} = \sqrt{((-15)-(0))^2+((-20)-(-5))^2}$

Rajeev buys good worth Rs 6650.He gets a rebate of 6% on it.After getting the rebate, he pays sales tax @10%. Find the amount he

finlep [7]

Rajeev will pay Rs 6876.10 for the goods.

Step-by-step explanation:

Given,

Worth of goods = Rs 6650

Rebate = 6%

Amount of rebate = 6% of worth of goods

Amount of rebate = $\frac{6}{100}*6650=0.06*6650$

Amount of rebate = Rs 399

Amount after rebate = 6650 - 399 = Rs 6251

Sales tax = 10%

Amount of sales tax = 10% of amount after rebate

Amount of sales tax = $\frac{10}{100}*6251=0.1*6251$

Amount of sales tax = Rs 625.10

Total amount of goods paid = Amount after rebate + sales tax

Total amount of goods paid = 6251+625.10 = Rs 6876.10

Rajeev will pay Rs 6876.10 for the goods.

G(n) = 3n - 3 f(n) = 2n - 4 Find g(-3) f(-3)

dlinn [17]

Answer:

G(-3) = -12, and F(-3) = -10.

Step-by-step explanation:

G(n) = 3n - 3

G(-3) = 3(-3) - 3, which is equivalent to -9 - 3, or -12.

F(n) = 2n - 4

F(-3) = 2(-3) - 4, which is equivalent to -6 - 4, or -10.

Please help!!! will pick brainliest

GaryK [48]

Answer:

432 cm^2

Step-by-step explanation:

Bottom rectangle:

24 * 9.5 = 228

Top rectangle:

Just move the tiny triangle over to the right side and you have a full rectangle.

24 * 8.5 = 204

Add the area of both rectangles to get the total area.

228 + 204 = 432

The area of the whole figure is 432 cm^2
