7(1-8n) = 7 - 56n Work - 7 - 7 x 8n= 7 - 56b
-5(1+2k)-8(-4+5k) = 27 - 50k Work - -5-10k+32-40k = 27-10k-40k = 27-50k

What is the value of the discriminant for the quadratic equation 0 = x + 2 + x2? Discriminant = b2 – 4ac

navik [9.2K]

Ax^2 + bx + c = 0
x^2 + x + 2 = 0

a = 1
b = 1
c = 2

b^2 - 4ac

1^2 - 4(1)(2)
= 1 - 8
= -7

The value of the discriminant is -7.

What is the angle measure of an arc bounding sector with an area of 5pie square miles?

Snowcat [4.5K]

if the diameter is 20, the its radius must be half that or 10.

$\textit{area of a sector of a circle}\\\\ A=\cfrac{\theta \pi r^2}{360}~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ A=5\pi \\ r=10 \end{cases}\implies \begin{array}{llll} 5\pi =\cfrac{\theta \pi (10)^2}{360}\implies 5\pi =\cfrac{5\pi \theta }{18} \\\\\\ \cfrac{5\pi }{5\pi }=\cfrac{\theta }{18}\implies 1=\cfrac{\theta }{18}\implies 18=\theta \end{array}$
