Left side = 170-58 =121'

Bottom side = 96-4 =92'

Now let's calculate the upper oblique (slantwise) side by Pythagoras

oblique² = 92²+28² = 9248 & oblique =√9248 = 96.167'

The perimeter of the backyards = 96.167+93+92+121 = 402.167 ft

A particle p is moving along the x-axis the displacement x metres from O can be writen as x=t^5-12t²+9 find the velocity

Lisa [10]

Answer:

$v = t (5t^{3} - 24)$

Step-by-step explanation:

We are given an expression to solve for the displacement (x), so in order to find velocity (v), we need to differentiate the function.

============================================================

Solving :

⇒ $\frac{dx}{dt} = \frac{d}{dx} (t^{5} - 12t^{2} + 9)$

⇒ $v = (5)t^{5-1} - (2)12t^{2-1} + 0$

⇒ $v = 5t^{4} - 24t$

⇒ $v = t (5t^{3} - 24)$

Using this equation, we can find the velocity if a value of t is given.

Answer: a) 138.32 and b) 35 years approx.

Step-by-step explanation:

Since we have given that

$R(t)=21.4e^{0.13t}\\\\C(t)=18.6e^{0.13t}$

So, Profit is given by

$Profit=R(t)-C(t)\\\\Profit=21.4e^{0.13t}-18.6e^{0.13t}\\\\Profit=e^{0.13t}(21.4-18.6)\\\\Profit=2.8e^{0.13t}$

Difference in years of 1990 and 2020=30

So, Profit becomes :

$P(30)=2.8e^{0.13\times 30}\\\\P(30)=2.8\times 49.40\\\\P(30)=138.32$

(b) How long before the profit found in part (a) is predicted to double? (Round your answer to the nearest whole number.) years after 1990.

So, profit doubles , we get :

$138.32\times 2=2.8e^{0.13t}\\\\276.65=2.8e^{0.13t}\\\\\dfrac{276.65}{2.8}=e^{0.13t}\\\\98.80=e^[0.13t}\\\\\ln 98.80=0.13t\\\\4.593=0.13t\\\\\dfrac{4..593}{0.13}=t\\\\35.33=t$

Hence, a) 138.32 and b) 35 years approx.
