Elly buys 75 shares of stock in a mutual fund for a total investment of $450. She sells 50 shares of her stock for total proceeds of $400. Determine if Elly made a profit or loss, and how much per share.
Answer:
She made a profit of $ 2 on each share of stock
Step-by-step explanation:
Elly buys 75 shares of stock in a mutual fund for a total investment of $450.
cost of 1 share of stock= $ 450/75
= $ 6
She sells 50 shares of her stock for total proceeds of $400.
selling price of 1 share of stock=$ 400/50

What is the volume in cubic meters of a greenhouse that is 30 feet long, 15 feet wide, and 8 feet high
The volume of the greenhouse is approximately 101.952 cubic meters.
To calculate the volume of the greenhouse in cubic meters, we first need to convert the measurements from feet to meters.
1 foot is approximately equal to 0.3048 meters.
Given measurements:
Length = 30 feet
Width = 15 feet
Height = 8 feet
Converting to meters:
Length = 30 feet * 0.3048 meters/foot ≈ 9.144 meters
Width = 15 feet * 0.3048 meters/foot ≈ 4.572 meters
Height = 8 feet * 0.3048 meters/foot ≈ 2.4384 meters
Now, we can calculate the volume in cubic meters:
Volume = Length * Width * Height
Volume ≈ 9.144 meters * 4.572 meters * 2.4384 meters ≈ 101.952 cubic meters
The volume of the greenhouse is approximately 101.952 cubic meters.

Upon graduation from college, Warren Roberge was able to defer payment on his $22,000 student loan for 3 months. Since the interest will no longer be paid on his behalf, it will be added to the principal until payments begin. If the interest is 6.94 % compounded monthly , what will the principal amount be when he must begin repaying his loan?
Using the compound interest formula, we calculate that after 3 months, the new principal amount that Warren Roberge will owe on his student loan is $22,000(1 + 0.0694/12)^(12*0.25).
Explanation:To find the principal amount that Warren Roberge will owe when he begins repaying his student loan, we need to consider the interest compounding monthly over the 3-month deferment period. The formula for compound interest is: A = P(1 + r/n)^(nt), where A is the amount of money accumulated after n years, including interest, P is the principal amount (the initial amount of money), r is the annual interest rate (in decimal form), n is the number of times that interest is compounded per year, and t is the time in years.
In this case, P = $22,000, r = 6.94/100 = 0.0694, n = 12 (since the interest is compounded monthly), and t = 3/12 = 0.25 (since the deferment period is 3 months, or 0.25 years).
Substituting these values into the formula, we find that A = $22,000(1 + 0.0694/12)^(12*0.25).
Therefore, after 3 months, the principal amount that Warren will owe on his student loan will be A.

How much would $400 be worth after 16 years, if it were invested at 3% interest compounded annually? (Use the formula below and round your answer to the nearest cent.)
A(t)=P(1+ r/n)^nt
Final answer:
Using the compound interest formula A(t) = P(1 + r/n)^(nt) with the values P = $400, r = 3%, n = 1, and t = 16 years, the investment would grow to $722.44.
Explanation:
To calculate how much $400 would be worth after 16 years when invested at a 3% interest rate compounded annually, we can use the compound interest formula A(t) = P(1 + r/n)^(nt). In this formula, P represents the principal amount ($400), r is the annual interest rate (3% or 0.03), n is the number of times interest is compounded per year (1 for annually), t is the number of years the money is invested (16 years), and A(t) is the amount of money accumulated after t years, including interest.
To solve for A(t), we substitute the values into the formula:
A(t) = 400(1 + 0.03/1)^(1×16)
A(t) = 400(1 + 0.03)^16
A(t) = 400(1.03)^16
After calculating the power term:
A(t) = 400(1.80611123467)
Finally, we multiply the principal amount by the factor:
A(t) = $722.44
The $400 investment at 3% interest compounded annually would be worth $722.44 after 16 years.

| 2z - 3| = 4z - 1
The solution to the given inequality expression is -1 and 2/3.
Solving inequality expressionTo solve the equation |2z - 3| = 4z - 1, we need to consider two cases: one where the expression inside the absolute value is positive and another where it is negative. Remember that the absolute value of a number is always non-negative.
Case 1: (2z - 3) is non-negative (greater than or equal to zero).
In this case, |2z - 3| = 2z - 3. So we have:
2z - 3 = 4z - 1
Now, let's solve for 'z':
2z - 4z = -1 + 3
-2z = 2
z = 2 / -2
z = -1
Case 2: (2z - 3) is negative (less than zero).
In this case, |2z - 3| = -(2z - 3) = -2z + 3. So we have:
-2z + 3 = 4z - 1
Now, let's solve for 'z':
-2z - 4z = -1 - 3
-6z = -4
z = -4/-6
z = 2/3
Therefore, we have two possible solutions: z = -1 and z = 2/3.

An incompressible steady flow pattern is given by u=x^3+2z^2 and w=y^3-2yz. what is the most general form of the third component v(x,y,z) which satisfies continuity?
Final answer:
For an incompressible steady flow with u and w components as [tex]x^{3} +2z^{2}[/tex] and [tex]y^{3}-2yz[/tex], respectively, the v component of the velocity that satisfies continuity is of the form [tex]v(x,y,z)=y^{2}-3x^{2y}+f(x,z)[/tex], where f(x, z) is an arbitrary function of x and z.
Explanation:
The question is asking for the most general form of the third component v(x, y, z) of a velocity vector field that satisfies the continuity equation for an incompressible steady flow. Given that the u and w components of the velocity are
u = [tex]x^{3} +2z^{2}[/tex] and
w = [tex]y^{3}-2yz[/tex],
respectively, we can use the continuity equation for incompressible flow, which is
∇ ⋅ β = 0,
or written out,
∂u/∂x + ∂v/∂y + ∂w/∂z = 0.
By substituting the given components into the continuity equation, and taking the respective partial derivatives, we get:
∂u/∂x = [tex]3x^{2}[/tex],
∂w/∂z = -2y,
So, the continuity equation becomes: [tex]3x^{2}[/tex] + ∂v/∂y - 2y = 0.
Rearranging terms we get: ∂v/∂y = 2y - [tex]3x^{2}[/tex]
Integrating with respect to y, we find that v must generally be of the form: [tex]v(x,y,z)=y^{2}-3x^{2y}+f(x,z)[/tex], where f(x, z) is an arbitrary function of x and z since the partial derivative with respect to y of any function that does not contain y will be zero, preserving the continuity.
