Answer:

2 27/34.

Step-by-step explanation:

2 3/8 = (2*8 + 3) / 8 = 19/8.

4 1/4 = (4*4 + 1) / 4 = 17/4 = 34/8.

So the ratio of 2 3/8 to 4 1/4 = 19 to 34, so we can write:-

19 / 34 = x / 5

34x = 5*19

x = 95/34

2 27/34.

Which second degree polynomial function f(x) has a lead coefficient of 3 and roots 4 and 1?

Stella [2.4K]

Answer:

f(x) = 3x² - 15x + 12

Step-by-step explanation:

Given f(x) has roots x = a and x = b, then

(x - a) and (x - b) are the factors

f(x) is then the product of the factors

f(x) = a(x - a)(x - b) ← where a is a multiplier

Given roots are x = 4 and x = 1, then

(x - 4) and (x - 1) are the factors

With a = 3, then

f(x) = 3(x - 4)(x - 1) ← expand factors using FOIL

= 3(x² - 5x + 4) ← distribute

= 3x² - 15x + 12
