Answer:

vertex form f(x) = (x - 4)^2 - 4

Step-by-step explanation:

f(x)=x^2-8x+12 in vertex form

look at -8x

take -8 divide it by 2 and square result get 16

f(x) = x^2 - 8x + 16 - 16 + 12

f(x) = (x - 4)^2 - 16 + 12

f(x) = (x - 4)^2 - 4

vertex form f(x) = (x - 4)^2 - 4

A factory produce bicycles at a rate of 110+0.5t^2-0.9t bicycles per week (t in weeks)

klasskru [66]

Answer:

221

Step-by-step explanation:

Day 8 is the first day of the second week.

Day 21 is the last day of week 3.

We need to know the n umber of bicycles made from t = 1 to t = 3

The function is b(t) = 110 + 0.5t^2 - 0.9t, where t is in weeks.

We need to integrate the function with the limits of 1 to 3.

$\int_{1}^{3} (110 + 0.5t^2 - 0.9t) dt$

$\int_{1}^{3} (110 + \dfrac{t^2}{2} - \dfrac{9t}{10}) dt$

$= 110t + \dfrac{t^3}{6} - \dfrac{9t^2}{20} \Biggr|_{1}^{3}$

$= 330.45 - 109.72$

$= 220.7333$
