A chemist makes a solution of acetic acid. The chemist makes at least 2 liters and wants to store the solution in several smalle

r jars. One jar holds 0.5 liter, which the chemist fills completely, and the remaining jars each hold 0.35 liter.
​Which inequality can be used to determine the number of smaller jars, n, the chemist needs?
A
2≤0.5n+3.52≤0.5n+3.5
B
2≥0.5n+3.52≥0.5n+3.5
C
2≤0.35n+0.52≤0.35n+0.5
D
2≥0.35n+0.52≥0.35n+0.5

What is the surface area of the cube with the given edge length, s?
iren [92.7K]
A cube has 6 sides.
 first calculate the area of 1 side  and then multiply it by 6
 

the area for one side = S^2 ( or SxS)

15^2 = 15 x 15  = 225 square inches 

now multiply that by 6:
225 x 6 = 1350 square inches total

the answer is B.

What kind of problem do we need to use “indefinite integral” to solve? Use a real life example to explain.
anastassius [24]

Answer:

Indefinite integration acts as a tool to solve many physical problems.

There are many type of problems that require an indefinite integral to solve.

Basically indefinite integration is required when we deal with quantities that vary spatially or temporally.

As an example consider the following example:

Suppose that we need to calculate the total force on a object placed in a non- uniform field.

As an example let us consider a rod of length L that posses an charge 'q' per meter length and suppose that we place it in a non uniform electric field which is given by

E(x)=\frac{E_{o}}{e^{kx}}

Now in order to find the total force on the rod we cannot use the similar procedure as we can see that the force on the rod varies with the position of the rod.

But if w consider an element 'dx' of the rod at a distance 'x' from the origin the force on this element will be given by

dF=E(x)\times qdx\\\\dF=\frac{qE_{o}}{e^{kx}}dx

Now to find the whole force on the rod we need to sum this quantity over the whole length of the rod requiring integration, as shown

\int dF=\int \frac{qE_{o}}{e^{kx}}dx

Similarly there are numerous problems considering motion of particles that require applications of indefinite integration.

Which system of equations can you use to find the roots of the equation? x3 – 10x = x2 – 6 y = x3 – x2 + 10x + 6 y = 0 y = x3 –
Maslowich

Answer:

answer is:

y=x^{3}-10 x,y=x^{2}-6

Step-by-step explanation:

we are asked to find which system of equations can we use to find the roots of the equation:

x^{3}-10x=x^{2}-6

since the system of equation in last part is given as:

y=x^{3}-10 x,y=x^{2}-6

so, on equating both the equations i.e. on equating both the values of 'y' we get the desired equation as:

x^{3}-10x=x^{2}-6.

PLS HELP ME IS EZZZZZ
Arte-miy333 [17]

Answer:

825.663706143591cm

Step-by-step explanation:

80cm × 4 = 320cm

100cm × 3 = 300cm

The radius is 40

40 × 2 = 80cm

Circumference is πd

π80 = 251.327412287183

÷ 2 = 125.663706143591cm

In total

320 + 300 + 80 + 125.663... =

825.663706143591cm
