Answer:

  • No

Step-by-step explanation:

Let's assume (x + 5) is the factor of f(x) = x^3 − 4x^2 + 3x + 7

then f(-5) should be equal to zero. Verifying:

  • f(-5) =
  • (-5)^3 - 4(-5)^2 +3(-5) + 7 =
  • -125 - 100 - 15 + 7 =
  • -233

Since -233 ≠ 0, the statement is false, so (x + 5) is not a factor of given polynomial

Suppose the diameter of a circle is \color{green}{4}4start color green, 4, end color green. what is its radius?
taurus [48]
By definition we have the relationship between the diameter of a circle and its radius is as follows:
 r = d / 2
 where
 r: radio
 d: diameter
 Since the diameter of the circle is 4, then the radius will be given by
 r = (4) / 2 = 2
 answer
 the radius of the circle is 2 units.
