Tamiku [17]

by pythagorean formula, the last side is √(61)

by cos rule

cos A

=  \frac{ {6}^{2}  + 61 -  {5}^{2} }{2 \times 6 \times  \sqrt{61} }  \\  =  \frac{72}{12 \sqrt{61} }   \\  =  \frac{6}{ \sqrt{61} }

A = 39.81

-(5y) - y = 18
-6y = 18
y = -3
x = 5(-3)
x = -15
(-15, -3)

5x + 4(-7x - 3) = -35
5x -28x -12 = -35
-23x = -23
x = 1
y = -7(1) - 3
y = -10
(1,-10)

If using the method of completing the square to solve the quadratic equation x2 - 6x – 7 = 0, which number would have to be adde
Vanyuwa [196]

Answer:

(-3)^2

Step-by-step explanation:

You add 7 on both sides, giving you x^2 - 6x = 7

Then, take half of b, and square it. Giving you x^2 - 6x +(-3)^2 = 7

The answer will be (-3)^2 for this question, but this is not the full solution.

Hope this helped. Good luck on the rest!

How do you do this question?
vivado [14]

Answer:

-1

Step-by-step explanation:

dy/dt = y² − 1 = (y + 1) (y − 1)

At t = 0, y = 0, and dy/dt = -1.  Therefore, y is initially decreasing.

As y decreases, dy/dt increases.  When y = -1, dy/dt = 0 and changes signs from negative to positive.

As y increases above -1, dy/dt again becomes negative.  So y continues to approach -1 as t approaches infinity.
