Q1 - D. f(x) =
Q13 - A. ±1, ±2, ±3, ±4, ±6, ±8, ±12, ±24.
Q14 - A.
Step-by-step explanation:
Question 1:
We know that rational roots always occurs in pairs. So, the zeros of the function will be 5, -3, -1+3i, -1-3i
So, the factored form is
i.e.
i.e.
i.e.
Hence, the polynomial function is .
Question 13:
Rational Zeros Theorem states that 'If p(x) is a polynomial with integer coefficients and if is a zero of p(x) = 0. Then, p is a factor of the constant term of p(x) and q is a factor of the leading coefficient of p(x)'.
Let, is a zero of
. Then, p is a factor of -24 and q is a factor of 1.
Thus, possible values of p = ±1, ±2, ±3, ±4, ±6, ±8, ±12, ±24 and q = ±1
This gives, possible values of are ±1, ±2, ±3, ±4, ±6, ±8, ±12, ±24.
Question 14:
We have, f(x) = 7x + 6 and g(x) =
Then, (f+g)(x) = f(x) + g(x) = 7x + 6 +
So, (f+g)(x) =
Amount paid by Mary for her computer is .
<u>Solution: </u>
Given that, Sam purchased a computer for .
Price of the printer that Mary purchased was the price that Sam paid.
Need to calculate amount Mary pay for her computer. Assuming that Mary purchased same computer that is purchased by Sam and store selling the computer have same rates for all customers .
So, amount Mary pay for computer = Amount Sam paid for computer =
Hence, amount paid by Mary for her computer is .
