Answer:
At a point when r = 6 ft
The rate of change of Area with time is given as
(dA/dt) = 36π = 113.1 ft²/min
Step-by-step explanation:
Area of a circle, A = πr²
A = πr²
(dA/dt) = (dA/dr) × (dr/dt)
(dA/dr) = 2πr, (dr/dt) = 3
(dA/dt) = 2πr × 3 = 6πr
At a point when r = 6 ft
(dA/dt) = 6πr = 6π × 6 = 36π = 113.1 ft²/min
Answer:
is the number such that lim h → [infinity] eh + 1 h = 1.
Step-by-step explanation:
The number e is known as the Euler's constant or Euler's number. The number basically is a mathematical expression that is equal to the rational number 2.71828. In addition, it is also the base of the natural logarithm or the Naperian logarithms. It is the number that the natural logarithm is equal to one. In addition, it is the limit of :

as n approaches infinity.
The expression is calculated as a sum of the infinite series
e =

Answer:
5. 66%
Step-by-step explanation:
Sales tax = $19.80
Cost of item before sales tax = $330
Cost of item after sales tax = 19.80+19.80 + 19.80+330
= $349.80
Sales tax rate
19.80349.80×100%5.66%\begin{lgathered}\frac{19.80}{349.80} \times 100\% \\ 5.66\%\end{lgathered}
349.80
19.80
×100%
5.66%
So rate of sales tax is 5.66%
