Answer:

r = 1728 units

Step-by-step explanation:

Volume of sphere:  V = (4/3)(pi)(r^3), were r is the radius.

Solving this for r^3, we get

      V                           V                          7234.56 units^3

------------- = r^3 = ----------------   so that   --------------------------

(4/3)(pi)                 (4/3)(3.14)                           4.19

Thus, r = 1728 units

Ms. wilson draws a model of the factorization of a polynomial with integer factors. her model is partially complete. a 2-column
lana [24]

The equation represented by Ms. Wilson's model is n² + 13n + 40 = (n + 8)(n + 5)

<h3>How to determine the equation of the model?</h3>

The partially completed model is given as:

    |  n

    |  n²

5   | 5n  |  40

By dividing the rows and columns, the complete model is:

    |  n    | 8

n   |  n²  |  8n

5   | 5n  |  40

Add the cells, and multiply the leading  row and columns

n² + 8n + 5n + 40 = (n + 8)(n + 5)

This gives

n² + 13n + 40 = (n + 8)(n + 5)

Hence, the equation represented by Ms. Wilson's model is n² + 13n + 40 = (n + 8)(n + 5)
