You foil for this one so it means that you multiply -3 with g, then multiply -3 with -f, you should get -3g+3f, but i'm not sure if i did it correctly if i did get it wrong then my bad

For an acute angle θ, the equation sin(θ)=cos(6) is true. What is the value of θ? Show or explain your answer

sweet [91]

Answer:

$\theta= 84$

Step-by-step explanation:

Given

$\sin(\theta) = \cos(6)$

Required

Find $\theta$

In trigonometry,

If $\sin(\theta) = \cos(\alpha)$ , then

$\theta + \alpha = 90$

So, in this case:

$\theta + 6= 90$

Subtract 6 from both sides

$\theta + 6-6= 90-6$

$\theta= 90-6$

$\theta= 84$

Hence, the value of $\theta$ is 84 degrees

What is the center of a circle whose equation is x2 + y2 – 12x – 2y + 12 = 0?

Vadim26 [7]

Answer:

(6,1)

Step-by-step explanation:

Just look for the terms with x and y in them. Divide their coefficients by two, and multiply by -1. And then put them in an ordered pair.

So in this case, -12x --> 6 and -2y --> 1

Obviously the more orthodox way would be to actually complete the square, but I'm lazy, this way is faster, and since this seems to be multiple choice, as long as you have the correct answer, it shouldn't matter.

If using the method of completing the square to solve the quadratic equation x^2+13x+15=0 which number would have to be added to

Ray Of Light [21]

Answer:

The number to be added to complete the square is (13/2)^2

But the solved value for x are:

x = 11.71 or -1.28

Step-by-step explanation:

x ^ 2 + 13x + 15 = 0

x^2 + 13x = -15

(The coefficient of x^2 is 1, hence needless diving through)

Add the square of half the coefficient of x to both sides

x^2 + 13x + (13/2)^2 = -15 + ( 13/2)^2

(x + 13/2)^2 = -15 + 169/4

(x + 13/2)^2 = 109/4

Take the square of both sides

x + 13/2 = +-10.44/ 2

x = 10.44/2 + 13 /2

x = 23.44/2

x = 11.71

x = 10.44/2 - 13/2

x = -2.56/2

x = -1.28

Therefore x = 11.71 or -1.28

But the number to be added to complete the square is (13/2)^2
