A square with side x, is changing with time where x(t)=3t+1. What is the formula for the rate of change of the area of the squar

lawyer [7]

Answer:

A' = 6(3t +1)

Step-by-step explanation:

The area is the square of the side length, so ...

A = (3t +1)²

The derivative with respect to t is then

A' = 2(3t +1)·(3) = 6(3t +1)

If you like, you can multiply out the area expression first, then differentiate.

A = 9t² +6t +1

A' = 18t +6

This can be factored, if you like, to ...

A' = 6(3t +1)

Suppose that the population of a town Increases by 3% each year. the population of the town today is 25,000

jolli1 [7]

Answer:

The population of town after 1 year is 25,750 .

Step-by-step explanation:

Given as :

The rate of increase in the population of town each year = 3 %

The initial population of town = 25,000

Let the population of town after one year = x

So,

The population after n year = initial population × $(1+\dfrac{\textrm rate}{100})^{\textrm n}$

Or, The population after 1 year = 25,000 × $(1+\dfrac{\textrm 3}{100})^{\textrm 1}$

Or, The population after 1 year = 25,000 × $(1.03)^{1}$

Or, The population after 1 year = 25,000 × 1.03

∴ The population after 1 year = 25,750

Hence The population of town after 1 year is 25,750 . Answer

At a certain clothing store, all shirts are on sale for the same price. Mr.Chan bought 6 shirts and paid a total of $62.99, incl

baherus [9]

You would subtract the tax first which 62.99-2.99=60$. Then you would divide the $60 left by 6 and 60 divided by 6 equals 10 so each shirt costs $10.
