8 0
C² - 5c - 24 = 0
c = <u>-(-5) +/- √((-5)² - 4(1)(-24))</u>
                         2(1)
c = <u>5 +/- √(25 + 96)</u>
                  2
c = <u>5 +/- √(121)
</u>               2 <u>
</u>c = <u>5 +/- 11
</u>            2
c = <u>5 + 11</u>      c = <u>5 - 11</u>
          2                    2
c = <u>16</u>            c = <u>-6</u>
       2                    2
c = 8              c = -3

Can u explain how to get the answer???
Mazyrski [523]

Answer:

Since there are 8 sections and 3 are even

We consider that 3/8

We now multiply by 120 since they said 120 times it is spun

3/8 x 120 = 45

Given cube inscribed in sphere with edges √243 cm. Find the volume of sphere
g100num [7]

Answer:

10,300.77 cm³

Step-by-step explanation:

Radius = ½(diameter)

Diagonal:

sqrt[243 + 243]

sqrt(486)

Diameter

sqrt(486 + 243)

27

Radius: 27/2

Volume of sphere:

4/3 × pi × r³

4/3 × 3.14 × (27/2)³

10300.77 cm³

Given the system of equations, what is the solution?
Elena L [17]

Answer:

{(-34/7, -16/7)}

Step-by-step explanation:

Rearrange values, multiply to solve for x.

(5) 2y = 3x + 10

(-2) 5y = 4x + 8

Solve for x.

10y = 15x + 50 ↓

-10y = -8x -16

Combine and evaluate.

0 = 7x + 34

Subtract 34 from both sides.

7x = -34

Divide both sides by 7.

x = \frac{-34}{7}

Plugin x value into either equation to solve for y.

2y = (3 × \frac{-34}{7}) + 10

2y = \frac{-102}{7} + 10

2y = \frac{-32}{7}

y = \frac{-16}{7}
