During a rainfall, the depth of water in a rain gauge increases at a rate modeled by r(t)=0.5+tcos(πt380) , where t is the time in hours since the start of the rainfall and r (t) is measured in centimeters per hour. how much did the depth of water in the rain gauge increase from t = 0 to t = 3 hours?

Answers

Answer 1

During a rainfall, the depth of water in a rain gauge increases  1.4658 cm.

What is a cosine function?

Cosine is a trigonometric function, used in a right triangle to define the ratio of the side adjacent to and the hypotenuse of this triangle.

During a rainfall, the depth of water in a rain gauge increases at a rate modeled by:

[tex]R(t)=0.5+tcos(\frac{\pi t^3}{80})[/tex]

Where:

t is the time in hours since the start of the rainfall R(t) is measured in centimeters per hour.

So, when t=0, the depth of water will be:

[tex]R(t)=0.5+tcos(\frac{\pi t^3}{80})\\R(0)=0.5+0cos(\frac{\pi 0^3}{80})\\R(0)=0.5 cm[/tex]

So, when t=3, the depth of water will be:

[tex]R(t)=0.5+tcos(\frac{\pi t^3}{80})\\R(3)=0.5+3cos(\frac{\pi 3^3}{80})\\R(3)=1.9658 cm[/tex]

So the difference will be:

[tex]R(3)-R(0)=1.4658 cm[/tex]

stocks x and y have the following data. assuming the stock market is efficient and the stocks are in equilibrium, which of the following statements is correct?

Answers

The correct statement is these two stocks must have the same dividend yield.

What is the dividend yield of the stock?

Dividend yield of a stock is the dividend per share divided by the total market price of the stock.

Dividend yield = dividend per share / market price

Dividend per share = market value x (required return - expected growth)

Dividend per share for Stock X = $25 x (10% - 7%) = $0.75

Dividend per share for Stock Y = $40 x (12% - 9%) = $1.20

Dividend yield for Stock X = 0.75 / 25 = 0.03

Dividend yield for Stock Y = 1.20 / 40 = 0.03

Here is the complete question:

Stocks A and B have the following data. Assuming the stock market is efficient and the stocks are in equilibrium, which of the following statements is CORRECT? A B Required return 10% 12%Market price $25 $40Expected growth 7% 9%

Answers

The value of WACC from the given information is about 7.4%.

What is WACC?

WACC is defined as the weighted average cost of capital. It is the rate at which a firm is projected to pay all of its security holders on average to finance its assets.

The firm's cost of capital is frequently referred to as the WACC. It is important to note that the external market, not management, determines this.

The formula of WACC is:

[tex]\text{Weighted Average Cost of Capital (WACC)} = \dfrac{\text{Annual Dividend}}{\text{Sales price of Proffered Stock} - \text{Sales price} \times \text{FC}}[/tex]

According to the given information,

Annual Dividend = $8.50,

Sales price of Proffered Stock =$120.

Flotation Cost(FC) = 4%.

Now, putting the values in the formula of WACC,

[tex]\text{Weighted Average Cost of Capital (WACC)} = \dfrac{\text{Annual Dividend}}{\text{Sales price of Proffered Stock} - \text{Sales price} \times \text{FC}}\\\\\text{Weighted Average Cost of Capital (WACC)} =\dfrac{8.5}{\$120- (\$120 \times 4\%)}\\\\\text{Weighted Average Cost of Capital (WACC)} =0.074(Approx.)[/tex]

Then, the WACC in terms of percentage is 7.4%.

The area of the shaded region is = (72π - 144) mm²

What is the area of a shaded region?

The area of a shaded region is that enclosed part of a plane figure that is shaded.

Suppose;

A square is inscribed in a circle with a diameter of 12√2 millimeters. Everything outside of the square is shaded.

Let's first find the area of the circle.

Area of circle = [tex]\mathbf{\pi r^2}[/tex]

Area of circle = [tex]\mathbf{\pi \times (\dfrac{12 \sqrt{2}}{2})^2}[/tex]

Area of circle = 72π sq mm

We know that the side of the inscribed square = [tex]\mathbf{\dfrac{12\sqrt{2}}{\sqrt{2}}}[/tex] = 12 mm

Area of the square = side(L)²

Area of the square = 12²

Area of the square = 144 sq mm

Now, the area of the shaded region can be estimated by finding the difference between the area of the square from that of the circle.

Area of a cylinder, V= πr²h

Where:

r= base radiush= height.

Area of the base, A= πr²

So,

volume of the cylinder;

V= A×h

For instance,

if volume of a cylinder is 50cm³ and area of the base is 10cm²

V= A*h

50 = 10 × h

50 = 10h

h = 50/10

h = 5cm

If the area of the base is doubled at a constant volume, that is A = 20cm², V = 50cm²

V= A×h

50 = 20 × h

50 = 20h

h = 50/20

A relation that assigns to each element x from a set of inputs or ________ exactly one element in a

Answers

The complete sentence is:

"A relation that assigns to each element x from a set of inputs or domain exactly one element in a..."

How to complete the sentence?

First, let's describe what a mathematical relation is.

A relation between two variables maps the element from the set of inputs, also called the domain, into the set of outputs, also called the range.

So we have something like:

y = h(x)

Where the relation h() is mapping the element x into the element y.

Now, the sentence that we need to complete is:

"A relation that assigns to each element x from a set of inputs or ________ exactly one element in a..."

So we need a synonym for the set of inputs, which we already know that is also called the domain, so the complete sentence would be:

"A relation that assigns to each element x from a set of inputs or domain exactly one element in a..."
