Hey there!!

The equation given = 3x² + 15x - 18 = 0

a = 3

b = 15

c = -18

Quadratic formula =

- b ± √(b² - 4ac ) / 2a

- 15 ± √ ( 225 + 216 ) / 6

-15 ± √ (  441 ) / 6

-15 ±  21 / 6

- 15 + 21 / 6

=  6 / 6 = 1  is one of the answer.

- 15 - 21 / 6

- 36 / 6  = -6 is the second answer.

Answers = 1 and -6

Hope my answer helps!

The volume of a sphere is 972(pi)ft3.
pav-90 [236]

Here are some simple equations that can be a life saver with this stuff :

vol of a sphere =

v = \frac{3}{4} \pi \: {r}^{3}

Circumference =

2 \times \pi \times r

sorry this might not be very helpful. I haven't don't this since last year. You basically have to work backwards. so plug in 972 for V and then do (3/4)×3.14.

then take the answer u got for ^^ and divide it by 2? not sure.

Graph the set of points. Which model is most appropriate for the set?
Tamiku [17]
Check the slope between the moving points 

<span>slope between (–6, –1) & (–3, 2) = 1 </span>
<span>slope between (-3, 2) & (–1, 4) = 1 </span>
<span>slope between (-1, 4) & (2, 7) = 1 </span>

<span>the points are collinear and make an angle of 45 degrees with the x-axis </span>

<span>we can have an equation of a line passing through (-6,-1) and slope 1 as </span>

<span>(y + 1) = 1(x + 6) </span>
<span>y = x + 5 is your linear model mostly</span>
