Answer:

Step-by-step explanation:

The formula of an area of a trapezoid:

$A=\dfrac{b_1+b_2}{2}\cdot h$

b₁, b₂ - bases

h - height

From the picture we have

$b_1=19yd,\ b_2=5yd,\ h=9yd$

Substitute:

$A=\dfrac{19+5}{2}\cdot9=\dfrac{24}{2}\cdot9=12\cdot9=108\ yd^2$

If Cp = Rs 660, Loss percent = 5% find Sp

Aneli [31]

Answer:

SP = 627 Rs

Step-by-step explanation:

Percentage loss is calculated as

$\frac{CP-SP}{CP}$ , then

$\frac{660-SP}{660}$ = 5% = 0.05 ( multiply both sides by 660 )

660 - SP = 33 ( subtract 660 from both sides )

- SP = - 627 ( multiply both sides by - 1 )

SP = 627 Rs

F(x)=2x^2+7x-5+g(x)=-8x^2-3x+5 what is g(x) + f(x)

Licemer1 [7]

F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5

g(x) + f(x)
-8x² - 3x + 5 + 2x² + 7x - 5
-8x² + 2x² - 3x + 7x + 5 - 5
-6x² + 4x + 0

-2x(3x - 2)

The line ab has midpoint (-2,4). a has coordinates (3,-2). find the coordinates of b

hodyreva [135]

Answer:

B = (-7,10)

Step-by-step explanation:

Given that , a line AB has midpoint (-2,4) and the coordinates of A is ( 3 , -2). We need to find out the coordinates of B .

Let coordinate of B be ( p,q ). We can use midpoint formula , as ,

=> Midpoint = ( x₁ + x₂ / 2 , y₁ + y₂/2 )

=> ( -2,4 ) = ( p + 3)/2 , ( q -2 )/2

On comparing ,

=> -2 = p + 3/2

=> p + 3 = -4

=> p = -3 - 4

=> p = (-7)

Also :-

=> q - 2/2 = 4

=> q -2 = 8

=> q = 8 + 2

=> q = 10

<h3>Hence the coordinates of B is ( -7,10 ) .</h3>
