Multiply the polynomials (x+3)(x^2-6x+5)

LekaFEV [45]

Answer:

$\huge\boxed{x^3-3x^2-13x+15}$

Step-by-step explanation:

$\text{Use FOIL:}\\\\(a+b)(c+d)=ac+ad+bc+bd$

$(x+3)(x^2-6x+5)\\\\=(x)(x^2)+(x)(-6x)+(x)(5)+(3)(x^2)+(3)(-6x)+(3)(5)\\\\=x^3-6x^2+5x+3x^2-18x+15\\\\\text{combine like terms}\\\\=x^3+(-6x^2+3x^2)+(5x-18x)+15\\\\=x^3-3x^2-13x+15$

What is the average rate of change for ƒ(x) = −2^x + 70 over the interval 2 ≤ x ≤ 6? A) −15 B) −16 C) −30 D) −32

N76 [4]

Answer:

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b ] = [ 2, 6 ], thus

f(b) = f(6) = - $2^{6}$ + 70 = - 64 + 70 = 6

f(a) = f(2) = - 2² + 70 = - 4 + 70 = 66

average rate of change = $\frac{6-66}{6-2}$ = $\frac{-60}{4}$ = - 15 → A
