What does complumentary mean in geometry?

1 answer:

8 0

If you have a right triangle and one angle in the triangle is 45 degrees, the other would have to be complementary (an angle that adds up to another to form a right angle) so the other angle would have to be 45 degrees to make that a right angle 90 degrees. So complementary angles are two angles that add up to equal 90 degrees.

use the elimination method to solve the system of equations. choose the correct ordered pair. 6x-4y=-8 and 11x+4y=76

nika2105 [10]

Answer:

(4,8)

Step-by-step explanation:

6x-4y=-8

11x+4y=76 eliminate y

6x+11y=-8+76

17 x=68

x=68/17=4

substitute x :

6x-4y=-8

6(4)-4y=-8

-4y=-8-24

y=-32/-4

y=8

Answer:

Loss of $1.16 millions.

Step-by-step explanation:

It is given that the profit made by company is $1.38 million

It is $2.54 million higher than the last year.

The last year profit which is represented by (p) can be calculated as:

p = Current year profit - 2.54

p= 1.38 - 2.54

p = -1.16

This mean last year there was a loss of $1.16 millions last year in company.

alexira [117]

Answer:

I = 1.47001

Step-by-step explanation:

we have the function

$f(x,y)=sin(x^2y^2)\\$

In polar coordinates we have

$x=rcos\theta\\y=rsin\theta$

and dA is given by

$dA=rdrd\theta$

Hence, the integral that we have to solve is

$I=\int \limt_2^4 \int \limit_0^{\pi /2}sin(r^4cos^2\theta sin^2\theta)rdrd\theta$

This integral can be solved in a convenient program of your choice (it is very difficult to solve in an analytical way, I use Wolfram Alpha on line)

I = 1.47001

Hope this helps!!!
