D, 7:5 because the original ratio is 21:15 (comedies:action), which can be dived by 3. 21/3=7 15/3=5
Answer:
43.9% people surveyed owned a cell phone
Step-by-step explanation:
Using a venn diagram
Number of people with cell phone = 232
Total number of people surveyed= 528
Percentage of people owning cell phone =232/528 × 100/1 = 43.9%
We can simply multiply the roots together to find the original function.
(x + 2)(x - 4)(x - 4)(x - 3)
FOIL.
x^2 - 4x + 2x - 8(x - 4)(x - 3)
Combine like terms.
x^2 - 2x - 8(x - 4)(x - 3)
FOIL.
x^3 - 2x^2 - 8x - 4x^2 + 8x + 32(x - 3)
Combine like terms.
x^3 - 6x^2 + 32(x - 3)
FOIL.
x^4 - 6x^3 + 32x - 3x^3 + 18x^2 - 96
Combine like terms.
<h3>x^4 - 9x^3 + 18x^2 + 32x - 96 is the original function with the given roots.</h3>
