Your grandmother originally invested R 2950.00, which grew at 5% interest for 18 years to become R 6649.93.

To determine how much your grandmother originally invested, we need to use the formula for the future value of a lump sum, which is:

FV = PV x (1 + r)^n

Where:

FV is the future value of the investment

PV is the present value or the initial investment

r is the interest rate

n is the number of compounding periods

We know that the investment was made 18 years ago, and the interest rate was 5%. We also know the future value of the investment, which is R 6649,93. Therefore, we can rearrange the formula to solve for PV:

PV = FV / (1 + r)^n

Plugging in the values, we get:

PV = 6649.93 / (1 + 0.05)^18 ≈ R 2950.00

Answer:

The relationship between the mass m in kilograms of an organism and its metabolism p in calories per day can be represented by p = 73.3m³ . To find the metabolism of an organism that has a mass of 16 kilograms, we can substitute m = 16 into the equation:

p = 73.3m³ p = 73.3(16)³ p = 73.3(4096) p = 299,648 calories per day

Therefore, an organism with a mass of 16 kilograms has a metabolism of 299,648 calories per day.

I hope that helps!

Step-by-step explanation:

An organism with a mass of 16 kilograms has a metabolism of 299,708.8 Calories per day according to the given relationship.

We can use the given formula to find the metabolism P of an organism with a mass of 16 kilograms:

P = 73.3m³

where m = 16 kg

Substituting the value of m:

P = 73.3(16)³

P = 73.3(4096)

P = 299,708.8 Calories per day.

1888 ounces bags of dried dill can be made

Addition: Addition is one of the four basic operations of arithmetic, the other three being subtraction, multiplication and division. The addition of two whole numbers results in the total amount or sum of those values combined

let us consider that, x = dried cilantro , y = dried dill

so by the given information we can write addition of dried cilantro an dried dill is equal to 253

x + y = 253

and also said that container of dried cilantro is 17 pounds heavier than that of container of dried dill so we can write, x = y + 17

substitute the value of x in the 1st equation

y + 17 + y = 253

2y + 17 = 253

2y = 253 - 17

2y = 236

y = 236/2

y = 118

Answer:

You may make dried dill in 1888 ounce bags.

Step-by-step explanation:

What does addition mean?

One of the four fundamental operations in mathematics is addition. The other three are subtraction, multiplication, and division. When two whole numbers are added, the sum or total of those values is obtained.

Consider that x represents dried cilantro and y represents dry dill.

So, using the information provided, we can say that adding dry cilantro and dried dill equals 253.

x + y = 253

and added that a container of dried cilantro weighs 17 pounds more than a container of dried dill, leading us to derive the equation x = y + 17

substitute the value of x in the 1st equation

y + 17 + y = 253

2y + 17 = 253

2y = 253 - 17

2y = 236

y = 236/2

y = 118

so there is 118 pounds of

and it will be sold in 1 ounce bags

we know, 1 pound = 16 ounces

so 118 pounds = (118×16) = 1888 ounces

which will make 1888 ounces bags.

Answer:

x = 25

Step-by-step explanation:

Given the midpoint of two points (x1,y1) and (x2,y2) = ((x1 + x2) / 2, (y1 + y2) / 2))

Midpoint of (x,6) and (-9,14) = ((-9 + x) / 2, (14 + 6) / 2) = (8,10).

The y coordinates cancel out because the midpoints work, so we can set the x value of the first coordinate as a midpoint of the second coordinate.

(-9 + x)/2 = 8

×2 ×2

(-9 + x) = 16

-9 + x = 16

+9 +9

x - 9 + 9 = 16 + 9

x = 25

___________

We can test this answer by substituting our answer back into the midpoint formula.

x = 25 → ((-9 + x) / 2, (14 + 6) / 2) = (8,10)

((-9 + 25) / 2, (14 + 6) / 2)) = (16/2, 20/2) = (8,10)

Hello.

First, "half a number" means we divide that number by 2.

Let's say the number is z.

Divide z by 2:

\(\displaystyle\frac{z}{2}\)

Add 5 to it:

\(\displaystyle\frac{z}{2} +5\)

Now, this expression equals 11:

\(\displaystyle\frac{z}{2} +5=11\)

Subtract 5 from both sides:

\(\displaystyle\frac{z}{2} =11-5\)

\(\displaystyle\frac{z}{2} =6\)

Now, in order to get rid of the fraction, we should multiply the entire equation by 2:

\(\displaystyle\frac{z}{2} *2=6*2\)

\(z=6*2\)

The equation for traveling x miles in the cab can be written as:

Cost = $0.60 + $0.14 * x. The cab charges $0.88 for a ride of 2 miles. And the cab charges $1.72 for a trip of 8 miles.

a. The equation for traveling x miles in the cab can be written as:

Cost = $0.60 + $0.14 * x

b. To find the number of miles for a cab ride that costs $0.88, we can set up the equation:

$0.88 = $0.60 + $0.14 * x

Subtracting $0.60 from both sides, we get:

$0.88 - $0.60 = $0.14 * x

$0.28 = $0.14 * x

Dividing both sides by $0.14, we find:

x = $0.28 / $0.14

x = 2 miles

Therefore, the cab charges $0.88 for a ride of 2 miles.

c. To calculate the cost of a trip of 8 miles, we can substitute x = 8 into the equation:

Cost = $0.60 + $0.14 * 8

Cost = $0.60 + $1.12

Cost = $1.72

Therefore, the cab charges $1.72 for a trip of 8 miles.

The decrease in diameter of the bar due to the applied load is -0.005434905d and the final diameter of the bar is 1.005434905d.

A compressive load of 80,000 lb is applied to a bar with a circular section of 0.75 in diameter and a length of 10 in.

if the modulus of elasticity of the bar material is 10,000 ksi and the Poisson's ratio is 0.3.

We have to determine the decrease in diameter of the bar due to the applied load.

Let d be the initial diameter of the bar and ∆d be the decrease in diameter of the bar due to the applied load, then the final diameter of the bar is d - ∆d.

Length of the bar, L = 10 in

Cross-sectional area of the bar, A = πd²/4 = π(0.75)²/4 = 0.4418 in²

Stress produced by the applied load,σ = P/A

= 80,000/0.4418

= 181163.5 psi

Young's modulus of elasticity, E = 10,000 ksi

Poisson's ratio, ν = 0.3

The longitudinal strain produced in the bar, ɛ = σ/E

= 181163.5/10,000,000

= 0.01811635

The lateral strain produced in the bar, υ = νɛ

= 0.3 × 0.01811635

= 0.005434905'

The decrease in diameter of the bar due to the applied load, ∆d/d = -υ

= -0.005434905∆d

= -0.005434905d

The final diameter of the bar,

d - ∆d = d + 0.005434905d

a) Since the coefficient of x2 is negative, MU2 will always be non-negative as long as x2 ≤ 25.

Graphically, if we plot the utility function u(x1, x2) as a three-dimensional surface, it would be challenging to visualize without specific values for x1 and x2. However, we can analyze the partial derivatives at specific points to determine the slope in different directions.

b) The utility value of (22, 10) is higher than (21, 02), so (22, 10) is ranked higher.

c) Given prices P1 = 2, P2 = 1, and income m = -8, the problem becomes:

Maximize: -x1² + 150x1 - 2x2² + 100x2 + x1²²

Subject to: 2x1 + x2 ≤ -8

d) d. To solve the problem, we can use optimization techniques to find the optimal values of x1 and x2 that maximize the utility function while satisfying the budget constraint.

a. To determine if preferences are monotonic, we need to check if the marginal utility of each good is non-negative. The marginal utility of x1 (MU1) is given by the partial derivative of the utility function with respect to x1, and the marginal utility of x2 (MU2) is given by the partial derivative of the utility function with respect to x2.

MU1 = ∂u/∂x1 = -2x1 + 150 + 2x1^2 + 1

MU2 = ∂u/∂x2 = -4x2 + 100

To check for monotonicity, we need to verify if MU1 ≥ 0 and MU2 ≥ 0.

Setting MU1 ≥ 0:

-2x1 + 150 + 2x1^2 + 1 ≥ 0

2x1^2 - 2x1 + 151 ≥ 0

To find the roots of this quadratic equation, we can use the quadratic formula:

x1 = (-b ± √(b^2 - 4ac)) / (2a)

For this equation, a = 2, b = -2, and c = 151. Substituting these values into the quadratic formula, we get:

x1 = (-(-2) ± √((-2)^2 - 4(2)(151))) / (2(2))

x1 = (2 ± √(4 - 1208)) / 4

x1 = (2 ± √(-1204)) / 4

Since the discriminant (√(-1204)) is negative, the roots are complex, which means the quadratic equation does not have real solutions. Therefore, MU1 is not always non-negative.

Setting MU2 ≥ 0:

-4x2 + 100 ≥ 0

-4x2 ≥ -100

x2 ≤ 25

b. To find a bundle that is ranked higher than (21, 02) = (100, 100), we need to find a bundle (x1, x2) that results in a higher utility value than the given bundle.

Substituting (21, 02) into the utility function:

u(21, 02) = -(21^2) + 150(21) - 2(02^2) + 100(02) + (21^2)

= -441 + 3150 - 0 + 0 + 441

= 3150

To find a higher-ranked bundle, we need to increase the utility value. Let's consider the bundle (22, 10):

u(22, 10) = -(22^2) + 150(22) - 2(10^2) + 100(10) + (22^2)

= -484 + 3300 - 200 + 1000 + 484

= 3100

The utility value of (22, 10) is higher than (21, 02), so (22, 10) is ranked higher.

c. The consumer's utility maximization problem can be set up as follows:

Maximize: u(x1, x2) = -x1² + 150x1 - 2x2² + 100x2 + x1²²

Subject to: P1x1 + P2x2 ≤ m

where P1 and P2 are the prices of goods x1 and x2, respectively, and m is the consumer's income.
