Answer:

12

Step-by-step explanation:

The Pythagorean theorem is

a^2+b^2 = c^2  where a and b are the sides and c is the hypotenuse ( the side opposite the right angle)

a^2 + b^2 = c^2

Substitute the known values

5^2 + b^2 = 13^2

25+b^2 = 169

Subtract 25 from each side

25+b^2-25 =169-25

b^2 = 144

Take the square root of each side

sqrt(b^2) = sqrt(144)

b=12

Answer:

Given:

To find:

missing side b

Solution:

Using Pythagorean theorem,

(Hypotenuse² = base² + perpendicular²)

b² = c² - a²

= 13² - 5²

= 169 - 25

= 144

b = √144

= 12

Answer:

a.)

Step-by-step explanation:

because 3 to the left is a negative and 2 units up means positive

The answer is b=18. To solve, multiply 6 by 3 to get 18. This is called doing the inverse operation. Since the equation is a division equation, we would have to multiply in order to find the missing variable.

The given rational function is r(x) = 6x − 6 / x^2To determine the intercepts, the following conditions are applied

x-intercepts  When y = 0, the following equation is obtained:6x − 6 = 0x = 1Since the degree of the denominator is higher than the degree of the numerator, the x-axis is a horizontal asymptote. Therefore, the main answer is x-intercept: (1,0)y-intercept: (0,-1)Horizontal asymptote: y = 0Vertical asymptote: x = 0The conclusion is that the intercepts of the rational function r(x) = 6x − 6 / x^2 are:(1,0) for the x-intercept and (0,-1) for the y-intercept. The horizontal asymptote is y = 0 while the vertical asymptote is x = 0.

Answer:

Option F, 10 inches.

Step-by-step explanation:

For a circle of radius R, the perimeter is:

P = 2*pi*R

such that pi = 3.14

If we have a section of that circle defined by an angle θ, the length of the arc is:

A = (θ/360°)*P =  (θ/360°)* 2*pi*R

In this case, we have a circle whose radius is defined by the length of the windshield wiper.

We also know that in one 90° revolution (so it travels the length of the arc of 90° two times) the tip travels a distance of 31 in.

Then:

A = 2*[(90°/360°)*2*3.14*R] = 31in

We need to solve this for R.

R = 31in/( 2*(90°/360°)*2*3.14) = 9.8in

We can round this to the next whole number:

R = 10in

The correct option is F.

Answer:

y = 2x + 11

Step-by-step explanation:

To find the slope, use the equation (y2 - y1)/ (x2 - x1). You get (15 - 5)/(2 - (-3), or 2. Then, use the slope you just found in the equation y - y1 = slope (x - x1), or y - 15 = 2 (x - 2). Simplifying down you get y = 2x -4 + 15, or y = 2x + 11, which is your final answer.

The area of the rectangular base of his friend's tank is 468.75 square inches. So, Option D is correct.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

One of Julian's friends also has a rectangular aquarium.

The dimensions of his friend's tank are each exactly 1 1/4 times the dimensions of Julian's tank.

Let x be the length of Julian's tank.

Let y be the width of Julian's tank.

So, the Area of Julian's tank = length × Width

                                               = xy

Since we are given

300 = xy

Now we are given that the dimensions of his friend's tank are each exactly times the dimensions of Julian's tank.

So, the length of his friend's tank = 5/4 x

So, the width of his friend's tank = 5/4 y

So, Area of his friend's tank = ( 5/4 x) (5/4 y)

                                           = 25 / 16 xy

                                           = 25 / 16 (300)

                                           = 468.75

Hence the area of the rectangular base of his friend's tank is 468.75 square inches.

So, Option D is correct.

Step-by-step explanation:

The critical angle for the reversed glass would be 43.04 degrees.

Optical fibers are based on the principle of total internal reflection. An optical fiber consists of a cylindrical core that carries light along its length. The core is surrounded by a layer of cladding that reflects the light back into the core, preventing it from leaking out.

Therefore, the core must have a higher index of refraction than the cladding. The critical angle is defined as the angle of incidence at which light is refracted at 90 degrees and does not pass through the boundary of the two media. The critical angle is determined by the formula: Critical angle = sin^-1(n2/n1) Where n1 and n2 are the refractive indices of the two media.

Given that flint glass (n1) has an index of refraction of 1.66 and  crown glass (n2) has an index of refraction of 1.52, we can calculate the critical angle as follows:Critical angle = sin^-1(n2/n1)Critical angle = sin^-1(1.52/1.66)

Critical angle = sin^-1(0.9157)Critical angle = 66.38 degrees

Therefore, the critical angle for this optical fiber is 66.38 degrees. If the glass were reversed, the critical angle would still exist. However, it would be a different angle because the refractive indices of the two media would be different.

In this case, the critical angle would be defined as follows:Critical angle = sin^-1(n1/n2)Critical angle = sin^-1(1.66/1.52)Critical angle = sin^-1(1.0921)Critical angle = 43.04 degrees

In conclusion, the present value of your return from this investment, when the stock price is 98, is approximately $1.965.

To find the present value of your return from the investment, we need to calculate the value of the European put option at time t=1/2 and then discount it back to the present value using the nominal annual interest rate of 6 percent compounded monthly.

(a) If S(1/2) = 102:
To calculate the value of the European put option at time t=1/2, we need to determine if it is in-the-money or out-of-the-money.

The strike price is K=100, and since the stock price is greater than the strike price (102 > 100), the put option is out-of-the-money. In this case, the put option has no intrinsic value.

The present value of your return from this investment would be $5, as the put option has no value. There is no profit or loss.

(b) If S(1/2) = 98:
Similar to the previous case, we need to determine if the put option is in-the-money or out-of-the-money. Since the stock price is less than the strike price (98 < 100), the put option is in-the-money.

The intrinsic value of the put option is given by the difference between the strike price and the stock price:

K - S(1/2) = 100 - 98 = 2.

To calculate the present value of your return from this investment, we need to discount the intrinsic value of the put option back to the present value. The nominal annual interest rate of 6 percent compounded monthly translates to a monthly interest rate of 6% / 12 = 0.5%.

Using the formula for the present value of a future cash flow:
Present Value = Intrinsic Value / (1 + Monthly Interest Rate)^(Number of Months)

Number of Months = 1/2 years * 12 months/year = 6 months.

Present Value = 2 / (1 + 0.005)^(6)
Present Value ≈ $1.965.

In conclusion, the present value of your return from this investment, when the stock price is 98, is approximately $1.965.

The decision rule for testing the hypotheses at a 5% level of significance is as follows:

A. Reject H0 if p > 0.025.

Do not reject H0 if p ≤ 0.025.

In hypothesis testing, the p-value is compared to the significance level (α) to make a decision. If the p-value is less than or equal to the significance level, we do not reject the null hypothesis (H0). If the p-value is greater than the significance level, we reject the null hypothesis.

In this case, the null hypothesis (H0) is that the slope coefficient (β1) is equal to 0, while the alternative hypothesis (Ha) is that β1 is not equal to 0. To make a decision, we compare the p-value associated with the coefficient estimate (b1) to the significance level (α = 0.05).
