a is the beggining number and n is the amount of times needed to do this. if is 17 you would need to subtract 7 from the originol number 12 (a) that many times.

Need help please stressing out over this problem!?!?!

$v = \frac{4}{3} \times \pi \times {r}^{3}$

Finding the radius,

$d = 2r, \: r = \frac{d}{2} = \frac{8}{2} = 4inches$

Plugging in our values,

$v = \frac{4}{3} \times 3.14 \times {4}^{3} = \frac{4}{3} \times 3.14 \times 64 = 267.95 {inches}^{3} \\$

Rounding to the nearest whol number,

$v = 268 {inches}^{3}$

What is the discriminant of this equation?<br> 3x2 + 8x = 0

Likurg_2 [28]

If the 2 is an exponent, it should be marked as such.
“3x2” means 3x⋅2
“3x^2” means 3x²

3x²+8x = 0
Discriminant = 8²-4(3)(0) = 64
