Answers

Answer 1

(a) Concerning the coefficients of the equation for the volume of the eggplant ( [tex]V(ft^{3}) = 3.53\times 10^{-2}\cdot e^{2\cdot t^{2}}[/tex]), the units of the coefficients with values [tex]3.53 \times 10^{-2}[/tex] and 2 are cubic feet and [tex]\frac{1}{h^{2}}[/tex], respectively.

(b) Regarding the determination of the coefficients by linear regression, the scientist must plot the square of time versus the natural logarithm of the volume and he would have obtained that the intercept is the natural logarithm of constant A and the slope is constant B.

(c) After the solicitation of the European distributor of the film, the new formula is [tex]V' = 9.884\times 10^{-4}\cdot e^{1.543\times 10^{-7}\cdot t'^{2}}[/tex], where volume is in cubic meters and time is in seconds.

Note - The statement reports typing mistakes. We present the correct statement below:

The climatic moment in the film "The Eggplant that Ate New Jersey" comes when the brilliant young scientist announces his discovery of the equation for the volume of the eggplant: [tex]V(ft^{3}) = 3.53\times 10^{-2}\cdot e^{2\cdot t^{2}}[/tex], where [tex]t[/tex] is the time in hours from the moment the vampire injected the eggplant with a solution prepared from the blood of the beautiful dental hygienist.

(a) What are the units of [tex]3.53\times 10^{-2}[/tex] and [tex]2[/tex]?

(b) The scientist obtained the formula by measuring [tex]V[/tex] and [tex]t[/tex] and determining the coefficients by linear regression. What would he have plotted versus what on what kind of coordinates? What would he have obtained as the slope and intercept of his plot?

(c) The European distributor of the film insists that the formula must be given for the volume in cubic meters ([tex]m^{3}[/tex]) as a function of time, in seconds. Derive the formula.

(a) In this exercise, we must make use of principles for dimensional analysis. We know that the equation for the volume of the eggplant is represented by:

[tex]V(ft^{3}) = 3.53\times 10^{-2}\cdot e^{2\cdot t^{2}}[/tex] (1)

Dimensionally speaking, we have the following case:

[tex][L]^{3} = [A]\cdot e^{[B]\cdot [t]^{2}}[/tex] (2)

By direct inspection and some algebraic handling, we conclude that:

[tex][A] = [L]^{3}[/tex]

[tex][B] = [t]^{-2}[/tex]

Therefore, the units of [tex]3.53 \times 10^{-2}[/tex] and 2 are cubic feet and [tex]\frac{1}{h^{2}}[/tex], respectively.

(b) The curve fit for the exponential expression used by the scientist is of the form:

[tex]V = A\cdot e^{B\cdot t^{2}}[/tex] (3)

If we apply logarithms on both sides of the expression above, then we have the following form:

[tex]\ln V = \ln A\cdot e^{B\cdot t^{2}}[/tex]

[tex]\ln V = \ln A + B\cdot t^{2}[/tex] (4)

The scientist must plot the square of time versus the natural logarithm of the volume and he would have obtained that the intercept is the natural logarithm of constant A and the slope is constant B.

(c) An hour equals 3600 seconds and a cubic feet equals 0.028 cubic meters. Hence, we can adapt (1) to fulfill the requirements of the European film distributor by using the following conversions:

[tex]t' = 3600\cdot t[/tex] (5)

[tex]V' = 0.028\cdot V[/tex] (6)

Where:

[tex]t[/tex] - Time, in hours.[tex]t'[/tex] - Time, in seconds. [tex]V[/tex] - Volume, in cubic feet.[tex]V'[/tex] - Volume, in cubic meters.

By applying (5) and (6) in (1), we have the resulting formula:

[tex]V' = 0.028\cdot [3.53\times 10^{-2}\cdot e^{2\cdot \left(\frac{t'}{3600} \right)^{2}}][/tex]

[tex]V' = 9.884\times 10^{-4}\cdot e^{1.543\times 10^{-7}\cdot t'^{2}}[/tex]

The new formula is [tex]V' = 9.884\times 10^{-4}\cdot e^{1.543\times 10^{-7}\cdot t'^{2}}[/tex], where volume is in cubic meters and time is in seconds.

We kindly invite to check this question on exponential functions: https://brainly.com/question/2456547

Answer 2

After a small online search, I've found that the volume equation is:

[tex]V[ft^3] = 3.53 \cdot10^{-2} \cdot exp(2 \cdot t^2)[/tex]

a) We want to see what are the units of the first factor:

[tex]3.53 \cdot10^{-2}[/tex]

You can see that the volume is in cube feet, and the only part in the equation that can have units is this one, so the units of this factor should be cube feet.

b) On the vertical coordinate he would see the volume and on the horizontal coordinate he would see the time.

The graph of this function is an increasing exponential function, that grows slow at the beginning and then grows faster.

c) Remember that the term with the units is:

[tex]3.53 \cdot10^{-2}[/tex]

So we should write this as:

[tex]3.53 \cdot10^{-2} ft^3[/tex]

Now we know that:

[tex]1m^3 = 35.3 ft^3\\\\1 = \frac{1 m^3}{35.3 ft^3}[/tex]

Now we can multiply our measure by this to get:

[tex]3.53 \cdot10^{-2} ft^3 = ( \frac{1 m^3}{35.3 ft^3})*(3.53 \cdot10^{-2} ft^3) = 0.1 m^3[/tex]

Then the equation is:

[tex]V = 0.1m^3\cdot exp(2 \cdot t^2)[/tex]

Answers

Answer:

Step-by-step explanation:

When a player reaches 101 points, they win. So that means that Mack reached 101 points. Since his opponent was seven points behind, we can subtract 7 from 101 to find Mark's, that is Mack's opponent's, score:

the answer is D because
12-4= 8 and you will be left with 2x & 8 you divide both sides by 2 the 2 from 2x will cancel leaving you with x and 8 divided by 2 gives you 4
then if you say 4-12 that will give you -8 and you left with 2x & -8 you divide both sides by 2 leaving you with -4

A tank is full of water. Find the work W required to pump the water out of the spout. (Use 9.8 m/s2 for g. Use 1000 kg/m3as the weight density of water.)
(A water tank shaped like a triangular prism is given. The base of the prism is at the top and a spout is located at the top of the tank. The dimensions of the tank are 9 meters long, 4 meters wide, and 4 meters deep. The spout is 3 meters long.)

Answers

Answer:

W = 1.06 MJ

Step-by-step explanation:

- We will use differential calculus to solve this problem.

- Make a differential volume of water in the tank with thickness dx. We see as we traverse up or down the differential volume of water the side length is always constant, hence, its always 8.

- As for the width of the part w we see that it varies as we move up and down the differential element. We will draw a rectangle whose base axis is x and vertical axis is y. we will find the equation of the slant line that comes out to be y = 0.5*x. And the width spans towards both of the sides its going to be 2*y = x.

Equations are used to show the relationship between variables (usually x and y). The true statement about f(x) is that the range of f(x) is [tex]y \ge -8[/tex]

Given that:

[tex]f(x) = 2(x - 2)^2 - 8[/tex]

To identify the true statement, I will make use of graphical method.

See attachment for the graph of [tex]f(x) = 2(x - 2)^2 - 8[/tex]

From the attached graph, we can see that the graph as a minimum at:

[tex](x,y) = (2,-8)[/tex]

And it opens upward.

This implies that the minimum y-value of f(x) is at -8, and it has no maximum.

In other words, the range of the function is:

[tex]f(x) \ge -8[/tex]

Hence, the true statement is option (a):

When you are given an algebraic expression for the length of a segment, you can solve for that value by knowing that the sum of two segments AB + BC = AC.

Thus:

(x + 4) + (2x – 10) = (2x + 1)

[Regroup terms]

(x + 2x) + (4 – 10) = (2x + 1)

[Simplify]

(3x – 6) = (2x + 1)

[subtract 2x from both sides to isolate the variable]

(3x – 6) – 2x = (2x + 1) – 2x

[Regroup terms]

(3x – 2x) – 6 = (2x – 2x) + 1

x – 6 = 1

[Add 6 to both sides to isolate the constant]

What is an arithmetic sequence?

Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as;

aₙ = a₁ + (n - 1)d

Given; The first term (a₁) is 92 and the fifth term (a₅) is 80.

Then the common difference between the terms will be given as;

a₅ = a₁ + (5 - 1)d

80 = 92 + 4d

-12 = 4d

d = -3

Then the missing terms will be

92, 92 - 3, 92 - 6, 92 - 9, and 92 - 12
