which second degree polynomial function has a leading coefficient of -1 an root 4 with multiplicity 2?

2 answers:

4 0

A root of 4 means the factor is (x - 4)
Multiplicity 2 means it has a power of 2 => => (x - 4)^2
Leading Coefficient -1 means it will be reflected opening downward
- (x - 4)^2
-(x^2 - 8x + 16)
-x^2 + 8x - 16

Divide x5+15x4+54x3−25x2−75x−34 by x+8.

Wittaler [7]

we are given

$x^5+15x^4+54x^3-25x^2-75x-34$

divide by x+8

we can use long division

so, we will get

$Quotient=x^4+7x^3-2x^2 -9x-3$

$Remainder=-10$

we can also write it as

$\frac{x^5+15x^4+54x^3-25x^2-75x-34 }{x+8}=(x^4+7x^3-2x^2 -9x-3)-\frac{10}{x+8}$ ..............Answer

Transversal c intersects the parallel lines, a and b, in the picture below.

lidiya [134]

Answer:

x = 96

Step-by-step explanation:

Since the lines a and b are parallel then

99 and x + 3 are alternate angles and congruent, hence

x + 3 = 99 ( subtract 3 from both sides )

x = 96 → C
