Two years ago, an investment of R1 500000 has increased to R1 700000 and has delivered R40 000 worth of dividends over the two years. Then the return on investment would be 16%.

We can use the following formula to calculate ROI:

ROI = (gain from investment - cost of investment) / cost of investment

where, gain from investment is the total value of the investment (including dividends), and cost of investment is the initial investment.

Using the values given in the question, we can calculate the ROI as:

ROI = ((R1,700,000 + R40,000) - R1,500,000) / R1,500,000 = R240,000 / R1,500,000

ROI = 0.16 or 16%

Therefore, the return on the investment is 16%.

It is a function that has different definitions based on the input.

In this problem, the function is defined by:

Due to the equal sign, x = 2 is part of the second definition, hence:

g(2) = 2³ - 9(2)² + 27(2) - 25 = 1.

Answer:

x = 65

Step-by-step explanation:

the sum of the interior angles of a quadrilateral = 360°

sum the angles and equate to 360

x + 95 + 118 + 82 = 360

x + 295 = 360 ( subtract 295 from both sides )

x = 65

Step-by-step explanation:

it seems you solved the tricky part yourself already.

just to be sure, let's do the first derivative here again.

the easiest way would be for me to simply multiply the functional expression out and then do a simple derivative action ...

f(t) = (t² + 6t + 7)(3t² + 3) = 3t⁴ + 3t² + 18t³ + 18t + 21t² + 21 =

= 3t⁴ + 18t³ + 24t² + 18t + 21

f'(t) = 12t³ + 54t² + 48t + 18

and now comes the simple part (what was your problem here, don't you know how functions work ? then you are in a completely wrong class doing derivatives; for that you need to understand what functions are, and how they work). we calculate the function result of f'(2).

we simply put the input number (2) at every place of the input variable (t).

so,

f'(2) = 12×2³ + 54×2² + 48×2 + 18 = 96 + 216 + 96 + 18 =

Step-by-step explanation:   Peter has less than charlie so charlie is more than or/and equal to being solid line underneath or solid line on graph represented by ≥ 65 stays equal to 65 or more which is a correct statement for charlie as charlie cards are increasing at 65 and has 65 and Peter is shown as ≤ 65 but is slightly wrong as we were told in question that 'he has just started collecting' this means it has to be or certainly less than charlie has - Just in diagram is interpreted as a dotted line on graph coordinates represented by < 65 instead IS LESS THAN 65 would be correct way to interprete inequality of Peters relationship value to that of charlie given amount

Answer:

10 quarters, 9 dimes, and 20 nickels.

Step-by-step explanation:

q - 1 = d, 2q = n or q = 1/2n

.25q + .10(q - 1) + .05(2q) = 4.40

.25q + .10q - .10 + .10q = 4.40

.45q - .10 = 4.40

.45q = 4.50

4.5/.45 = 10

He has 10 quarters, 9 dimes, and 20 nickels.

Answer:

\(-\frac{x^2y^2}{2}\)

Step-by-step explanation:

We have an extremely large equation and are asked to divide it, so let's solve it step-by-step :

Remove the parenthesis to make it easier to read :

\(\frac{-3x^3 *2x^3y^4z *3z^2}{4x^3z*3yz*3xyz}\)

Multiply the numerators :

\(\frac{-18x^6y^4z^3}{4*3*3x^3yyzzz}\)

Multiply the denominators :

\(\frac{-18x^6y^4z^3}{36x^4y^2z^3}\)

Apply the negative rule :

\(-\frac{18x^6y^4z^3}{36x^4y^2z^3}\)

Cancel the common factor which is 18 :

\(-\frac{x^6y^4z^3}{2x^4y^2z^3}\)

Apply the addition exponent rule :

\(\frac{y^4z^3x^{6-4} }{2y^2z^3}\)

Subtract :

\(\frac{x^2y^4z^3 }{2y^2z^3}\)

Apply the rule for y :

\(\frac{x^2y^{4-2} z^3 }{2z^3}\)

Subtract :

\(\frac{x^2y^2z^3 }{2z^3}\)

Cancel the common factor of z^3 :

\(-\frac{x^2y^2}{2}\)

A relation represented in an X-Y coordinate is the graph of a function if and only if there is no vertical line which passes through two points of the relation. In other words, each vertical line passes through at most one point in the relation.

This is the case of the given line. Therefore, it is the graph of a function.

Substitute x = 2 to y = 3x - 1

The correct answer is 3/2. In this case, x = 3/2, and its square, (3/2)^2 = 9/4, is rational. x satisfies the given condition.option (c)

To explain further, we need to understand the properties of rational and irrational numbers.

A rational number can be expressed as a fraction of two integers, while an irrational number cannot be expressed as a fraction and has non-repeating, non-terminating decimal representations.

In the given options, (a) √5102.0 (£) and (b) √2 are both irrational numbers.

Their squares, (√5102.0)^2 and (√2)^2, would also be irrational, violating the given condition. On the other hand, (d) 4/5 is rational, and its square, (4/5)^2 = 16/25, is also rational.

Option (c) 3/2 is rational since it can be expressed as a fraction. Its square, (3/2)^2 = 9/4, is rational as well.

Therefore, (c) 3/2 is the only option where x is rational, but its square is irrational, satisfying the condition mentioned in the question.

In summary, the number x that satisfies the given condition, where x^2 is irrational but x is rational, is (c) 3/2.option (c)

The rate of the plane in still air is 1130 km/hr and the rate of the wind is: 140 km/hr

Let the speed of plane in still air be p km/hr and wind speed be w km/hr.

The speed of plane with air is (p + w) km/hr and speed of plane against air is (p − w) km/hr

Flying with air: (p + w)⋅4 = 5080

or p + w = 1270  ----(1)

Flying against air: (p − w)⋅9 = 8910

or p − w = 990;(2)

Adding equations (1) & (2) we get,

(p + w) + (p − w) = 1270 + 990

or 2p = 2260

∴ p = 2260/2

= 1130 km/hr.

Putting p = 1130 in equation (1)

we get,

1130 + w = 1270

or

w = 1270 − 1130

w = 140  km/hr.

The speed of plane in still air is 1130 km/hr and wind speed is  140 km/hr.

The question is incorrect, The correct question is

Joseph selects a card from a standard deck of 52 cards and then replaces it afterwards. He decides to record the total number of red cards that he selects and calculates the proportion of red cards that he has selected so far after each pick. He then constructs a graph to visualize his results. Which of the following statements is FALSE?

A. The theoretical probability for selecting a red card in each pick is 0.5.

B. For a given number of selections, we can use Joseph's graph to find the number of diamonds that he has picked so far.

C. This is an example of the law of large numbers.

D. The relative frequency of selecting a red card changes with the increase in number of selections.

In the class, Lucy's score is 6.

In statistics, the median is the middle value in a sorted, ascending or descending list of numbers. Thus, it represents the midpoint of the data.

The median is often compared with other descriptive statistics such as the mean (average), mode, and standard deviation.

Since Lucy is one of the 29 students in the class and her score was the same as the median score for her class.

Thus, the median score will be 15th score (i.e. the midpoint of 29). Using the frequency in of each score from the figure, let's keep adding the frequency until we reach 15 and we will then check the corresponding score at the 15th position:

2 + 2 + 4 + 7 = 15

Thus, the the corresponding score at the 15th position is 6.

Therefore, the median score is 6 and consequently Lucy's score is 6.

These two perpendicular bisectors will meet at (1, 5, 1). These are the coordinates of the triangle's circumcenter.

the triangle's circle's center. It is the point where the "perpendicular bisectors," or lines parallel to the centre of both sides, cross.

The intersection of any two perpendicular bisectors of any two triangle sides is known as the circumcenter of a triangle ABC.

The equation y=1 is the perpendicular bisector of sides B(3,0) and C(3,2). Because AB's midpoint is at 3,1 and its slope is unknown. The perpendicular bisector has zero slope. The equation for such a line is y=y1.

The equation for the perpendicular bisector of A(0,0) and B is also x=1.5 (3,0). The reason is that AB has a midpoint of zero slope and (1.5,0). The perpendicular bisector's slope won't be clearly defined. The equation for such a line is x=x1.
