Final height of the rectangle picture of pharmacy area is 391 ft2.
ozzi

Answer:The height of the pharmacy area is 17 feet

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = length × width

The pharmacy area is rectangular. The height of the pharmacy area becomes the width of the rectangle.

The area of the pharmacy area is given as 391 ft^2

The length of the pharmacy area is given 23 feet

Therefore

23 × h = 391

h = 391/23 = 17 feet

The profit of football club after a take over is modelled by p(t)=t3-24t2+20t+120 in which years was the club making losd?
NemiM [27]

Answer:

16 years

Step-by-step explanation:

Given

P(t) = t^3 - 24t^2 + 20t + 120

Required

Year they made loss

P(t) = t^3 - 24t^2 + 20t + 120

Start by differentiating P w.r.t t

Using first principle:

\frac{dP}{dt} = 3t^2 - 48t + 20

Equate to 0, in order to solve for t

\frac{dP}{dt} = 0

So, we have:

3t^2 - 48t + 20 = 0

Solve using quadratic equation

t = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}

Where

a = 3, b = -48 and c = 20

So, we have:

t = \frac{-(-48) \± \sqrt{(-48)^2 - 4*3*20}}{2*3}

t = \frac{-(-48) \± \sqrt{2064}}{2*3}

t = \frac{-(-48) \± \45.4}{2*3}

t = \frac{48 \± \45.4}{6}

Split:

t = \frac{48 + \45.4}{6} or t = \frac{48 - \45.4}{6}

t = \frac{93.4}{6} or t = \frac{2.6}{6}

t = 15.56 or t = 0.43

Approximate to whole numbers

t = 16 or t = 0

<em>Hence, they made loss 16 years after they took over</em>
