Answer:
Choice b.
.
Step-by-step explanation:
The highest power of the variable in this polynomial is . In other words, this polynomial is quadratic.
It is thus possible to apply the quadratic formula to find the "roots" of this polynomial. (A root of a polynomial is a value of the variable that would set the polynomial to .)
After finding these roots, it would be possible to factorize this polynomial using the Factor Theorem.
Apply the quadratic formula to find the two roots that would set this quadratic polynomial to . The discriminant of this polynomial is .
.
Similarly:
.
By the Factor Theorem, if is a root of a polynomial, then would be a factor of that polynomial. Note the minus sign between and .
- The root corresponds to the factor , which simplifies to .
- The root corresponds to the factor , which simplifies to .
Verify that indeed expands to the original polynomial:
.
Answer:
0.3
Step-by-step explanation:
The value of p would be 40. This is because the ratio of p:q = 10:5. this could be simplify into p:q = 2:1. Applying the ratio p:20 = 2:1, P=40.
3.75.....rounded to the nearest dollar would be 4.00
