.Which one of the following is true when ds/dt=3t^2/2s

Mathematics
1 answer:
ser-zykov [4K]3 years ago
4 0
1) Given: ds / dt = 3t^2 / 2s

2) Separate variables: 2s ds = 3t^2 dt

3) Integrate both sides:

∫ 2s ds = ∫ 3t^2 dt

s^2 + constant = t^3 + constant

=> s^2 = t^3 + constant

=> s = √ (t^3 + constant)

Answer: option B.

OverLord2011 [107]

Answer:

1) C  2) (-2,0) 3) 4)  5) c )S={(0,3)} 6) (0,2) 7)  8) Missing graph 9) Vertical line (check below) 10) B 11)

Step-by-step explanation:

1) Solving by the Addition/Elimination Method. Firstly, let's reduce one variable by making some algebraic adjustments and then adding it up:

2) Solving by Substitution Method. Where y=x+2 is plugged in the 2nd equation.

3) Solving it, again, by the Substitution Method due to the I equation form:

4) By the Addition Method

5) To use the graph method to solve the system of Linear equations is possible by graphing each equation on the Cartesian Plane.

Check the graph below, this system has only one solution.

c)S={(0,3)}

2.375 in expanded form
kari74 [83]

Answer:

2375^-3

Step-by-step explanation:

Move the decimal place from 2.375 to the back of the number so it should look like this, 2375.

Than move the decimal place back to its original spot and count the amount of spaces you move. Remember, if you move forward, your exponent should be negative. For example, if the problem is 6.321, you would move the decimal place to the back like this, 6321. And then move it back to where it originally was, 6.321, the amount of spaces I moved was 3 spaces and I moved forward so It would be 6.321^-3

The table shows the predicted growth of particular bacterium after various numbers of hours. Write an explicit formula for the s
Oksana_A [137]

Answer:

D

-29

Step-by-step explanation:

Problem 1

In the first hour, the number of bacteria is 22

In the second hour,the number of bacteria is 44

It looks like the formula is some multiple of 22

That means you should pick D

Problem 2

n = 12

a = 15

d = - 4

an= 15 + (n - 1)*d

a12 = 15 + 11*(-4)

a12 = 15 - 44

a12 = - 29
