A)2.8
b1) 4.5/2.8
b2)impossible because if you want to do trigonometry you can't have that is an angle (Which is 148.1) larger than 90 degrees.
but if its angle BAF then the angle would be 2.8/5.3
c)41.32

If the center is (2,-1) and the radius is 5 what is the equation ?

HACTEHA [7]

The standard equation of a circle:

(y-k)² + (x-h)² = R² (1), where R is the radius and h, k are the coordinates of the center.: C(h, k)
In the problem the coordinates of the center C(2,-1).
Replace in (1) h by 2 and k by -1:

(y+1)² + (x-2)² = 25

A line passes through the point (-2, 8) and has a slope of-5/2.

chubhunter [2.5K]

Answer:

$y = -\frac{5}{2} x + 3$

Step-by-step explanation:

We are given that a line passes through (-2, 8) and has a slope of -5/2.

We want to write the equation of this line in slope-intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y-intercept.

Since we are already given the slope of this line, we can immediately plug it into the equation.

Replace m with -5/2.

$y = -\frac{5}{2} x+ b$

Now we need to find b.

As the equation passes through the point (-2, 8), we can use its values to help solve for b.

Substitute -2 as x and 8 as y.

$8 = -\frac{5}{2} (-2) +b$

Multiply.

8 = 5 + b

Subtract 5 from both sides.

3 = b

Replace b with 3 in the equation.

$y = -\frac{5}{2} x + 3$

PLEASE ANSWER FIRST GETS BRAINLIEST <br><br> x^2 +2= 38

Levart [38]

x^2 + 2 = 38

Subtract 2 from each side:

x^2 = 36

Take the square root of both sides:

x = √36

x = 6
