The required investment return on the fund is $6300 which is 16.8% of the investment.

Given that,
purchased 5,000 shares of a mutual fund at a price of $7.50 per share. Later sell those shares for $8.35 per share. During the time you owned the shares, the fund paid a dividend of $0.41 per share.

When someone applies for their money on something so that he can get a higher value in returns of his money.

Here,
Profit = 5000[8.35 + 0.41-7.50]
profit = $6300
Profit percentage = 6300 / [7.5 × 5000] × 100%
Profit percentage = 16.8%

Thus, the required investment return on the fund is $6300 which is 16.8% of the investment.

Step-by-step explanation:

(√2) can be interpreted as 2^(1/2) and the second term can be interpreted as 2^(1/3). The law of exponents tells us that we must add the exponents when multiplying two numbers with the same base. 1/2 + 1/3 is 3/6+2/6 = 5/6 so the final answer would be 2^(5/6)

The value of numerical expression 4(16)³ / 10³ will be 16.384.

Answer:

[tex]\textsf{a)} \quad y=1.8(3.2)^x[/tex]

[tex]\textsf{b)} \quad y=5(7)^x[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Function}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]

Given ordered pairs:

The y-intercept is the y-value when x = 0.

Therefore, as the y-intercept is 1.8, a = 1.8.

[tex]\implies y=1.8b^x[/tex]

Substitute point (1, 5.76) into the equation and solve for b:

[tex]\begin{aligned} y&=1.8b^x\\\implies 5.76&=1.8 \cdot b^1\\5.76&=1.8b\\b&=\dfrac{5.76}{1.8}\\b&=3.2\end{aligned}[/tex]

Therefore, the exponential equation is:

[tex]\boxed{y=1.8(3.2)^x}[/tex]

To complete the given table, simply substitute the values of x into the found equation:

[tex]\begin{array}{c|l}x&\phantom{189}y\\\cline{1-2} \vphantom{\dfrac12}}0&\phantom{18}1.8\\\vphantom{\dfrac12}}1&\phantom{18}5.76\\\vphantom{\dfrac12}}2&\phantom{1}18.432\\\vphantom{\dfrac12}}3&\phantom{1}58.9824\\\vphantom{\dfrac12}}4&188.74368\end{array}[/tex]

Given ordered pairs:

The y-intercept is the y-value when x = 0.

Therefore, as the y-intercept is 5, a = 5.

[tex]\implies y=5b^x[/tex]

Substitute point (2, 245) into the equation and solve for b:

[tex]\begin{aligned} y&=5b^x\\\implies 245&=5 \cdot b^2\\49&=b^2\\b&=\sqrt{49}\\b&=7\end{aligned}[/tex]

Therefore, the exponential equation is:

Answer:

21.64 % probability of rain at a random year

Step-by-step explanation:

79/365 * 100

21.64 %

78.9 kg.

To convert 78,900 grams to kilograms, we can divide the number of grams by 1,000. Since 1 kilogram is equal to 1,000 grams, dividing the number of grams by 1,000 will give us the equivalent number of kilograms.

Therefore, 78,900 grams is equivalent to 78,900 / 1,000 = 78.9 kilograms.

The zeros of the quadratic equation: h(x) = x^2 - 2x - 35

are -5 and 7, thus the correct option is B.

Here we have the quadratic equation:

h(x) = x^2 - 2x - 35

Using the quadratic formula we will get the two solutions:

[tex]x = \frac{2 \pm \sqrt{(-2)^2 - 4*1*-35} }{2*1} \\\\x = \frac{2 \pm 12 }{2} \\\\[/tex]

The solutions are:

x = (2 + 12)/2 = 7

x = (2 - 12)/2 = -5

With the help of similar triangles the height of Flagpole is 15.13 feet

what is similar triangle?

Triangles that are similar in shape but differ in size are known as similar triangles. Examples of related objects are all equilateral triangles and squares with any side length. To put it another way, if two triangles are comparable, then their corresponding angles and sides are congruent and equal in size.

solution:

let C is the point of reflection in triangle ABC and EDC

∠ ABC = ∠ EDC ( 90 Degree)

∠ ACD = ∠ ECD ( Reflective angle )

By symmetry,

AB/ED = BC/CD

5.6/ x  = 7.4 / 20

       x  =  15.13 feet

Hence the height of flagpole is 15.13 feet

What is area of circle?

The area encircled by a circle with radius r is known as πr^2 in geometry. Here, the Greek letter π stands for the constant proportion of a circle's circumference to its diameter, which is roughly equal to 3.14159.

Given:

A circular cookie cake costs $15.70.

The diameter of the cookie cake is 10 inches.

We have to find the cost of one square inch of the cookie cake.

Let the diameter is 10 inches.

So, the radius is 10/2 = 5 inches.

Area of circle = πr^2

                      = 3.14 x (5)^2

                       = 3.14 x 25

Area of circle  = 78.5 square inches.

So, the cost of one square inch cookie cake is,

78.5 / 15.70 = 5

Hence, the cost of one square inch of the cookie cake is $5.

Yes, human can distinguish pixels on a same-sized HDTV with 2 times 10 to the 6th power pixels.

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.

In the scientific form, we write a number in the form of base×10ⁿ.

Where 0 ≤ base < 10 and n can be any rational number.

Given,

Humans can distinguish up to 18,400,000 individual dots called pixels on a typical computer display

We need to check whether human distinguish pixels on a same sized HDTV with 2 x 10 to the 6th power pixels

2×10⁶ pixels.

Part A: The bill is $27.32

Part B: The percentage is 19%

My work:

Part A

   ?                   8

---------     =    ---------

25.30             100

equals 2.02400

then round to get the tax amount which is $2.02

to find the bill cost we need to add the tax and the cost of the meal:

2.02 + 25.30 = 27.32

Part B

to find the tip we need to subtract the bill from the total lunch cost:

27.32 + t = 4.92                              (t = tip)

32.24 - 27.32 = 4.92

So now that we know the tip we can figure out how much percentage that is of the cost of the meal:

4.92              ?

--------    =   --------

25.30         100

which equals 19.4466403/100
