Answer:
Ds/dt = 1,25 in/minute
Step-by-step explanation:
s is side of the cube
V(c) = s³
Differentiation on both sides of the equation with respect to time.
DV(c) / dt = 2*s* Ds/dt (1)
In that equation:
s = 2
DV(c) /dt = 5
By subtitution in equation (1)
5 = 2*s*Ds/dt
2*2*Ds/dt = 5
Ds/dt = 5/4 Ds/dt = 1,25 in/minute
The rate of change of the side length of the cube with respect to time, in inches per minute, at the moment when S = 2 inches is [tex]\dfrac{5}{12} \: \rm in^3/min[/tex]
How to calculate the instantaneous rate of growth of a function?Suppose that a function is defined as;
[tex]y = f(x)[/tex]
Then, suppose that we want to know the instantaneous rate of the growth of the function with respect to the change in x, then its instantaneous rate is given as:
[tex]\dfrac{dy}{dx} = \dfrac{d(f(x))}{dx}[/tex]
Let the rate of change of volume V with respect to time t is given by:
[tex]\dfrac{dV}{dt}[/tex]
And let the rate of change of volume S with respect to time t is given by:
[tex]\dfrac{dS}{dt}[/tex]
The relation between V and S is [tex]V = S^3[/tex]. Using this value, and the chain rule of differentiation, we get:
[tex]\dfrac{dV}{dt} = \dfrac{dS^3}{dt} = 3S^2\dfrac{dS}{dt} = 3S^2\dfrac{dS}{dt}\\\\\dfrac{dS}{dt} = \dfrac{1}{3S^2} \dfrac{dV}{dt}[/tex]
At S = 2, we are given that: [tex]\dfrac{dV}{dt} = 5 \: \rm in^3/min[/tex]
Putting these values in the equation for rate of S, we get:
[tex]\dfrac{dS}{dt} = \dfrac{1}{3S^2} \dfrac{dV}{dt}\\\\\dfrac{dS}{dt} = \dfrac{1}{3(2)^2}\times 5 = \dfrac{5}{12} \: \rm in^3/min[/tex]
Thus, the rate of change of the side length of the cube with respect to time, in inches per minute, at the moment when S = 2 inches is [tex]\dfrac{5}{12} \: \rm in^3/min[/tex]

Kelly had 13 cups of strawerries. She wants to divide the strawberries into small daily servings. How many 1/3 cup servings are in the 13 cups of strawberries?
Answer:
Number of servings in 13 cups strawberries = 39
Step-by-step explanation:
Total amount of strawberries Kelly has = 13 cups
Amount of strawberries Kelly used in one serving = [tex]\frac{1}{3}[/tex] cups
Number of servings in 13 cups of strawberries = [tex]\frac{\text{Total amount of strawberries with Kelly}}{\text{Strawberries required in one serving}}[/tex]
= [tex]\frac{13}{\frac{1}{3}}[/tex]
= [tex]13\times \frac{13}{1}[/tex]
= 39
Therefore, number of servings in 13 cups strawberries = 39

I can't see the words on your image very well but I can give you an explanation of the remainder theorem.
The theorem allows you to find the remainder of a division without doing the division itself.
You can find the remainder when a polynomial is divided by a linear expression like 3x - 2, for example, using this theorem.
An example will explain the method:
What is the remainder when x^3 - x^2 - 2x - 5 is divided by 2x - 1?
Put 2x - 1 = 0, this gives x = 0.5.
Now we plug x = 0.5 into the polynomial:
This = (0.5)^3 - (0.5)^2 -2(0.5) - 5 = -6.125
So the remainder is -6.125.
The formal definition is
The remainder when P(x) is divided by x - a is f(a).

Jeevan buys a bike for Rs 200000. At the end of 1 year, the value of the bike has depreciated by 15 percent.How much is the bike now worth?
Answer:
Rs.170000
Step-by-step explanation:
Given data
Cost price of bike= Rs 200000
Time= 1 year
Rate of depreciation= 15%
Let us apply the formula for depreciation
A=P(1-r)^t
A= 200000(1-0.15)^1
A= 200000(0.85)^1
A= 200000*(0.85)^1
A= 200000*(0.85)
A=Rs.170000
Hence the value of the bike will be Rs.170000

In a pet adoption center, there were a total of 252 cats and dogs. The number of cats exceeds the number of dogs by 44. Find the number of cats and dogs in the adoption center.
Answer:
cats = 148
dogs = 104
Step-by-step explanation:
(d + 44) + d = 252
2d + 44 = 252
-44 -44
2d = 208
divide by 2
d = 104
252 - 104 = 148
Which represents the volume of the cylinder, in cubic
units?
1207
1307
3002
325.7
Answer: 300π
Step-by-step explanation: Volume=(pi)(radius^2)(height)
Volume=(pi)(5^2)(12)
V=(pi)(25)(12)
V=(pi)(300)
The volume of the given cylinder is equal to 300π.
What is volume?Volume is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write volume as -
V = ∫∫∫ F(x, y, z) dx dy dz
Given is to find the volume of the cylinder shown in the image.
The volume of cylinder is given by -
V = πR²h
Here, the radius of the cylinder base is 5 units. The height of the cylinder
is 12 units. So, we can write the volume as -
V = π x 5 x 5 x 12
V = 300π
Therefore, the volume of the given cylinder is equal to 300π.
