Answer:

Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring. While factoring may not always be successful, the Quadratic Formula can always find the solution.

The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.

I need help with this question pls

Answer:61.8°

Step-by-step explanation:

Length of arc=(theta)/360 x 2 x π x radius

9.7=(theta)/360 x 2 x 3.14 x 9

9.7=56.52(theta)/360

cross multiply

9.7 x 360=56.52(theta)

3492=56.52(theta)

Divide both sides by 56.52

3492/56.52=56.52(theta)/56.52

61.8=theta

theta=61.8°

Reposting becuase it want let me edit my last one and somebody spam answered it.

Answer:

5Step-by-step explanation:

If you use the distance formula you can solve it pretty easily. The distance formula is:

d = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2} \\$

The two points you want are A and D. A is (-1, -4) and D is (3, -1). Plug that into the formula...

d = $\sqrt{(3 - (-1))^2 + (-1 - (-4))^2}$

d = $\sqrt{4^2 + 3^2}$

d = $\sqrt{16 + 9}$

d = $\sqrt{25}$

I can solve it in a different way if you want me to.

Dorothy is using fabric to cover a photo album the width of the fabric is 5/8 of a yard the area of the fabric is 5/16 square ya

saul85 [17]

For this case we assume that the photo album is rectangular in shape and therefore the fabric too. By definition, the area of a rectangle is given by:

$A = a * b$
