Given the function h(a) = -x^2+ 7x + 14, determine the average rate of change

Yakvenalex [24]

Answer:

- 2

Step-by-step explanation:

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

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

Here [a, b ] = [1, 8 ], thus

f(b) = f(8) = - 8² + 7(8) + 14 = - 64 + 56 + 14 = 6

f(a) = f(1) = - 1² + 7(1) + 14 = - 1 + 7 + 14 = 20

average rate of change = $\frac{6-20}{8-1}$ = $\frac{-14}{7}$ = - 2

Factor completely 3x^5-75x^3=

KiRa [710]

Answer:

$\huge\boxed{3x^5-75x^3=3x^3(x-5)(x+5)}$

Step-by-step explanation:

$3x^5=3\cdot x^{3+2}=3\cdot x^3\cdot x^2=\boxed{3x^3}\cdot x^2\\\\75x^3=25\cdot\boxed{3x^3}\\\\3x^5-75x^3=3x^3(x^2-25)=3x^3(x^2-5^2)\\\\\text{Use}\ a^2-b^2=(a-b)(a+b)\\\\=3x^3(x-5)(x+5)$
