The force field is given by F = xi + yj. The parabola goes from (0, 0) to (6, 36) and is parameterized as r(t) = ti + t^2j, where 0 ≤ t ≤ 6, and r'(t) = i + 2tj.

The work done by the force along the curve C1 is given by the integral below:∫ C 1 F.dr = ∫ 0 6 F(r(t)).r'(t)dt= ∫ 0 6 (ti + t^3j).(i + 2tj) dt= ∫ 0 6 (t + 2t^4) dt= (t^2/2 + 2t^5/5) [0,6]= 252

The straight line segment goes from (0, 0) to (6, 36) and is parameterized as r(t) = 6ti + 36tj, where 0 ≤ t ≤ 1, and r'(t) = 6i + 36j.

The work done by the force along the curve C2 is given by the integral below:∫ C 2 F.dr = ∫ 0 1 F(r(t)).r'(t)dt= ∫ 0 1 (6ti + 36tj).(6i + 36j) dt= ∫ 0 1 (36t + 216t) dt= (126t^2) [0,1]= 126

Therefore, the answer to the problem is: A. If C1 is the parabola: x = t, y = t^2, 0 ≤ t ≤ 6, then ∫C1 F.dr = 252.B.

If C2 is the straight line segment: x = 6t, y = 36t, 0 ≤ t ≤ 1, then ∫C2 F.dr = 126.

Step-by-step explanation:

The order of operations to evaluate these expressions is as follows:

Parentheses

Exponents

Multiplication/Division

Addition/Subtraction

So, for B.)

\(9^\frac{1}{2}+\sqrt{25}-8\div2+3^2\)

This can be rewritten as
\(9^\frac{1}{2}+25^\frac{1}{2}-8\div2+3^2\)

Since there are no parentheses, evaluate the exponents first:

\(3+5-8\div2+9\)

Next, there are no multiplication steps, but there is one division:

\(3+5-4+9\)

To finish, evaluate from left to right:

\(3+5-4+9\\8-4+9\\4+9\\13\)

Follow the same pattern for C.)

\((\frac{1}{2})(\frac{3}{5})(2^3-6)\)

This expression can be rewritten as

\((1\div2)(3\div5)(2^3-6)\)

First, evaluate the expressions in the individual parentheses, keeping in mind the expression \((2^3-6)\) must be evaluated following the same pattern (evaluate the exponent before subtracting six):

\((.5)(.6)(8-6)\\(.5)(.6)(2)\)

To finish, evaluate from left to right:

Step-by-step explanation:

The thermostat is set at 70 f. The medical examiner measured the liver temperature at 29.18 0c. The body been dead in 42.351 hours.

The time difference between the death of a body and finding a body is referred to as the post-mortem interval or PMI. It plays a vital role as it aids in determining the exact possible time of the death of the body. It gives us a time frame within which the identification of the human remains could possibly be made.

The liver temperature or rectal temperature is used to determine the true body temperature.

The body heat is lost at the rate of 1.5 degrees every hour. The body temperature of the dead body decreases at a rate of 1.5 degrees per hour.

As per the question, the thermostat is set at 70 F.

The liver temperature is 35.96 degrees Celsius. By converting it into Fahrenheit, it becomes 96.73 F.

F = 29.18×9/5+32

F = 84.524

So, from the normal body temperature, the rectal temperature is subtracted, and the difference is divided by 1.5. It is calculated by using the Glaister equation.

PMI = 98.7 F − dead body temperature / 1.5

PMI = 98.7−84.524/1.5

PMI = 42.351

Thus, the answer is 42.351 hours.

The extreme value of the function f(x) is the minimum value of the profit, which occurs when x = 15.

The given function f(x) represents the profit in thousands of dollars of selling x items. To find the meaning of the extreme value, we need to find the critical points of the function, which are the values of x where the derivative of the function is equal to zero or undefined.

The derivative of the given function is:

f'(x) = 12x - 180

Setting f'(x) = 0 to find critical points:

12x - 180 = 0

Solving for x, we get:

x = 15

So, x = 15 is the critical point of the function.

Now, we need to determine whether this critical point is a maximum or a minimum.

To do so, we can use the second derivative test. The second derivative of the given function is:

f''(x) = 12

Since f''(15) = 12 > 0, the critical point x = 15 is a minimum.

Therefore, the extreme value of the function f(x) is the minimum value of the profit, which occurs when x = 15. This minimum value represents the least amount of profit that can be earned by selling the items.

Step-by-step explanation:

Max has $35 a day to spend, and he can spend as much time as he likes on his leisure pursuits. Windsurfing equipment rents for $10 an hour, and snorkeling equipment rents for $5 an hour.

If Max equalizes the marginal utility per hour from windsurfing and from snorkeling, he can increase his total utility by spending less time windsurfing and more time snorkeling. The concept of total utility is based on the entire quantity of products consumed. On the other hand, the marginal utility is dependent on the unit quantity of a commodity consumed. Hence, the relationship between total utility and marginal utility is as follows: Marginal utility refers to the extra satisfaction generated from the consumption of the last unit of the product, whereas total utility refers to the total satisfaction derived from the consumption of all the goods.

According to the given information, Windsurfing equipment costs $10 per hour, and snorkeling equipment costs $5 per hour. Max's budget is $35, and he may devote as much time as he wants to his leisure activities. If Max balances the marginal utility per hour of windsurfing and snorkeling, he can increase his total utility by spending less time windsurfing and more time snorkeling, which is answer (D) can increase his total utility by spending less time windsurfing and more time snorkeling.

The span of {u, v} represents a plane in three-dimensional space. w is not in the span of {u, v}. the span of {u, v, w} is the entire three-dimensional space.

(a) The span of {u, v} represents a plane in three-dimensional space. Geometrically, this plane can be visualized as a flat surface extending infinitely in all directions. It includes all possible vectors that can be obtained by scaling and adding u and v. Any vector lying on this plane can be expressed as a linear combination of u and v.

(b) To determine if w is in the span of {u, v}, we need to check if w can be expressed as a linear combination of u and v. We can write w as follows:

w = a*u + b*v

Solving the system of equations formed by equating corresponding components, we have:

-2 = 3a - 2b

2 = -a + 2b

6 = -2a - 6b

Solving this system, we find that there are no values of a and b that satisfy all three equations simultaneously. Therefore, w is not in the span of {u, v}.

(c) The span of {u, v, w} is the entire three-dimensional space. To justify this, we consider the matrix A whose columns are u, v, and w:

A = [u v w] = [1 3 -2; -1 1 2; -2 -6 6]

We can row-reduce matrix A to its echelon form:

[1 3 -2; -1 1 2; -2 -6 6] -> [1 3 -2; 0 4 0; 0 0 0]

The echelon form shows that the columns of A are linearly independent, and they span the entire three-dimensional space. Therefore, any vector in three-dimensional space can be expressed as a linear combination of u, v, and w, indicating that the span of {u, v, w} is the entire three-dimensional space.

Step-by-step explanation:

The value of the standard deviation of the variance S is equivalent to 250 and the value of the variance (S) is equivalent to 62500.

Given that:

2Ax = 0.08

Ax = 0.2

A fully discrete whole life insurance issued to (x) is 1000.

Firstly we have to find out the value of variance S.

Variance S = (insurance issued)^2 * [2Ax - Ax^2]/(1- Ax)^2

Variance S = (1000)^2 * [0.08 -  0.2^2]/(1- 0.2)^2

Variance S = (1000)^2 * [0.04]/.64

Variance S = (1000)^2 * .0625

Variance S = 62500

Standard deviation of S = (insurance issued) * [\(\sqrt{2Ax - Ax^2}\)]/(1- Ax)

Standard deviation = 1000 * [\(\sqrt{0.08 - 0.2^2}\)]/(1- 0.2)

Standard deviation = 1000 * 0.2/0.8

Standard deviation = 1000 * 1/4 = 250
