Step-by-step explanation:

a) $11 = 3 lines of a classified ad

$x = 2 limes of a classified ad

cross multiply

3x = 22

divide by the coefficient of x

which is 3

3x/3 = 22/3

x = 7.33 approximately 7

x = 7.

b) $11 = 3 lines of a classified ad

$x = 5 lines of a classified ad

cross multiply

3x = 55

diviee by the coefficient of x

which is 3

3x/3 = 55/3

x =18.33 approximately 18

x =18.

The price of a certain computer stock t days after it is issued for sale is p(t)=100+20t−6t^2 dollars. The price of the stock in
Elanso [62]

Answer:

0 < t < \frac{5}{3}

After 1.67 days the stocks would be sold out.

Step-by-step explanation:

The price of a certain computer stock after t days is modeled by

p(t) = 100 + 20t - 6t²

Now we will take the derivative of the given function and equate it to zero to find the critical points,

p'(t) = 20 - 12t = 0

t = \frac{20}{12}

t = \frac{5}{3} days

Therefore, there are two intervals in which the given function is defined

(0, \frac{5}{3}) and (\frac{5}{3}, ∞)

For the interval (0, \frac{5}{3}),

p'(1) = 20 - 12(1) = 20

For the interval (\frac{5}{3}, ∞),

p'(2) = 20 - 12(2) = -4

Positive value of p'(t) in the interval (0, \frac{5}{3}) indicates that the function is increasing.

0 < t < \frac{5}{3}

Since at the point t = 1.67 days curve is showing the maximum, so the stocks should be sold after 1.67 days.
