Step-by-step explanation:

Given :

A cylindrical tank with radius 3m is being filled with water at a rate 4m³/min.

To Find :

How fast is the height of the water increasing.

Solution :

We know, volume of cylinder is given by :

[tex]V = \pi r^2h[/tex]       ....1)

Also, we have given that, [tex]\dfrac{dV}{dt} = 4 \ m^3/min[/tex] .

Differentiating equation 1) w.r.t  t we get :

[tex]\dfrac{dV}{dt} =3^2 \pi \dfrac{ dh }{dt}\\\\\dfrac{dh}{dt} = \dfrac{4}{3^2 \times \pi}\\\\\dfrac{dh}{dt} = 0.141 \ m/min[/tex]

Therefore, the height of water is increasing at a rate of 0.141 m/min.

The selling price of each of the remaining calculators should be $65 so that the merchant makes a profit of $150 in the entire operation.

The merchant bought a batch of 15 calculators at $40 each, so the total cost of the batch is:

Cost price = 15 calculators × $40/calculator

= $600

The merchant sold 5 calculators at a promotional price of $100 each.

So, the revenue from selling these 5 calculators is:

Revenue = 5 calculators × $100/calculator

= $500

Now, we need to calculate the profit made from the sale of these 5 calculators:

Profit = Revenue - Cost price

Profit = $500 - $600

= -$100 (Negative because the merchant incurred a loss on these 5 calculators)

The merchant wants to make a profit of $150 in the entire operation. So, adding the profit from selling the first 5 calculators:

Desired profit = $150

Current profit = -$100

Additional profit needed = Desired profit - Current profit

Additional profit needed = $150 - (-$100)

= $250

The merchant has 15 - 5 = 10 calculators left to sell.

We need to distribute the additional profit of $250 among the remaining 10 calculators:

Additional profit per calculator = Additional profit needed / Number of remaining calculators

Additional profit per calculator = $250 / 10 calculators

= $25

Now, let's calculate the selling price of each of the remaining calculators:

Selling price = Cost price + Additional profit per calculator

Selling price = $40 + $25 = $65

So, the selling price of each of the remaining calculators should be $65.

Answer:

The range of the function is:

Range R = {14, 17, 20}

Step-by-step explanation:

Given the function

[tex]f(x) = 3x + 2[/tex]

We also know that range is the set of values of the dependent variable for which a function is defined.  

In other words,  

We are given that the domain of the function is:

Domain D = {4, 5, 6}

Now,

substituting x = 4 in the function

f(4) = 3(4) + 2

f(4) = 12 + 2

f(4) = 14

substituting x = 5 in the function

f(5) = 3(5) + 2

f(5) = 15 + 2

f(5) = 17

substituting x = 6 in the function

f(6) = 3(6) + 2

f(6) = 18 + 2

f(6) = 20

Thus, we conclude that:

at x = 4, y = 14

at x = 5, y = 17

at x = 6, y = 20

Thus, the range of the function is:

Range R = {14, 17, 20}

Step-by-step explanation:

Answer:

3 months

Step-by-step explanation: Let after m months they saved same amount of money.

Given,

Saving of Jaclyn = $ 120,

Amount earned by him/her per month = $ 40,

So, the total amount contained by him/her in m months = Saving + earning for m months

= 120 + 40m,

Similarly, saving of Pedro = $ 180,

Amount earned by him/her per month = $ 20,

So, the total amount contained by him/her in m months = 180 + 20m

Thus, we can write,

120 + 40m = 180 + 20m

40m = 180 + 20m - 120

40m - 20m = 60

20m = 60

⇒ m =  = 3.

Hence, it will take 3 months before which Jaclyn and Pedro have saved the same amount of money.
