Area of trapezoid:

A = 1/2(b1+b2)h

where

b1 = 30,

b2 = 28+12 = 40

Triangle FOG

a^2 = c^2 - b^2

a^2 = 13^2 - 12^2

a^2 = 169 - 144

a^2 = 25

a = √25

a = 5

FO = 5 so height h = FO = 5

Now you can find the Area of trapezoid

A = 1/2(b1+b2)h

A = 1/2(30 + 40) (5)

A = 1/2(70)(5)

A = 175

A $60,000 piece of machinery depreciates in value at a rate of 11% per year. About what will its value be in 5 years?

kicyunya [14]

Answer:

$27000

Step-by-step explanation:

11% of 60000 is 3300 per year. You need the value for five years so multiply 3300 * 5 to get 33000. 33000 is the total depreciation of the five years. Then subtract 33000 from 60000 to get 27000.

A circle passes through (3,-1),(-2, 4), and (6,8)

Vaselesa [24]

Answer:

D = -6, E = -8 , F = 0

Step-by-step explanation:

standard form = $x^{2} + y^{2} + Dx + Ey + F = 0$

now, when circle passes through (3,-1);

⇒ $3^{2} + (-1)^{2} + D(3) + E(-1) + F = 0$

⇒ $3D - E + F + 10 = 0$ ...............( equation 1)

when circle passes through (-2,4);

⇒ $(-2)^{2} + 4^{2} + D(-2) + E(4)+ F = 0$

⇒ $-2D + 4E + F + 20 = 0$ ...............( equation 2)

when circle passes through (6,8);

⇒ $6^{2} + 8^{2} + D(6) + E(8) + F = 0$

⇒ $6D + 8E + F + 100= 0$ ................( equation 3)

by solving these 3 equations , we get;

D = -6, E = -8, F = 0

hence,

standard form = $x^{2} + y^{2} + Dx + Ey + F = 0$

= $x^{2} + y^{2} - 6x - 8y = 0$
