Given the binomials (x-1), (x-3), (x+3), (x+5), which one is the factor of f(x) = x^3 + 6x^2 + 12x +35?
kari74 [83]
The given polynomial is
f(x) = x³ + 6x² + 12x + 35

According to the Remainder Theorem, if x = a is a zero, then
f(a) = 0, and (x-a) is a factor.

Test (x-1):
f(1) = 1 + 6 +12 + 35 = 54   
Not a factor.

Test (x-3):
f(3) = 3³ +6*3² + 12*3 + 35 = 152
Not a factor.

Test (x+3):
f(-3) = (-3)³ + 6*(-3)² + 12*(-3) + 35 = 26
Not a factor.

Test (x+5):
(-5)³ + 6*(-5)² + 12*(-5) + 35 = 0
It is a factor.

Answer: (x+5) is a factor.

What is the axis of symmetry for f(x)=5(x+7)(x-5)
Harman [31]
<span>What is the axis of symmetry for f(x)=5(x+7)(x-5)?  Multiply out this polynomial to obtain the equation of a parabola in the form y = ax^2 + bx + c.

f(x) = 5(x^2 - 5x + 7x -35)

Holding the coefficient 5, we have 1x^2 - 2x - 35.  Here a = 1 and b = -2, and
thus x = -b / (2a) provides the x-coord. of the axis of symm.  It is:

x = -(-2) / (2*1) = 1.

The axis of symmetry is the vertical line x = 1.</span>

Question 22 mary has scored 79 , 91 , 64 , 65 , and 71 on her previous five tests. what score does she need on her next test so
steposvetlana [31]
So u want to add all of the previous scores together and divide them by the number of scores [i.e: 79+91+64+65+71= 370 then u divide. 370/5 (since there are 5 sets of scores) which gets you 74.] Then it's kind of a guess and check from there.
