A cell phone costs $750 and loses 28% of its value each year. What is the value of the phone after 2 years?

Answer:

8

Step-by-step explanation:

Let's call the missing side as x

Base on the pythagorean theorem, we have :
17² - 15² = x²

289 - 225 = x²

x² = 64

So, x equals 8.

To find the probability that the mean weight of 19 fish is between 16.1 and 20.6 lb, you would need to know the distribution of the weights of the individual fish. If the weights of the fish are normally distributed with a mean of 18.4 lb and a standard deviation of 2.5 lb, then you can use a normal distribution to find the probability that the mean weight of the 19 fish falls in the specified range.

How does probability work exactly?

Probability is calculated by dividing the total possible outcomes by the number of outcomes that are theoretically possible. Probability differs from odds in this regard. Calculating odds involves dividing the likelihood of a particular event by the likelihood that it won't occur.

Answer:

5/6

Step-by-step explanation:

Number of people in management majors = 10, number of people in world climate = 20.

Total number of people in class = Number of people in management majors + number of people in world climate = 10 + 20 = 30

Number of people with brown eyes = 10 / 2 + 20 / 2 = 5 + 10 = 15

Probability that a person chosen at random is a management major or has brown eyes = P(M or B)

P(M or B) = P(M) + P(B)

But probability of management major [P(m)] = Number of people in management majors / total number = 10 / 30 = 1/3

probability of brown eyes = Number of people with brown eyes / total number = 15 / 30 = 1/2

P(M or B) = P(M) + P(B) = 1/3 + 1/2 = 5/6

Answer:

1) AD = 9 in

2) DE = 9.25 in

3) ∠EDC = 36°

4) ∠AEB = 108°

5) 11.5 in

Step-by-step explanation:

1) AD = BC = 9in

2) AC = BD (diagonals are equal)

⇒ BD = 14.25

⇒ BE + DE = 14.25

⇒ 5 + DE = 14.25

DE = 9.25

3) Since AB ║CD,

∠ABE = ∠EDC = 36°

4) ∠ABE = ∠BAE = 36°

Also ∠ABE + ∠BAE + ∠AEB = 180 (traingle ABE)

⇒ 36 + 36 + ∠AEB = 180

∠AEB = 108

5) midsegment = (AB + CD)/2

= (8 + 15)/2

To write the big number in short form, we write them in the positive power of 10.

To write the very small number, we write them in the negative power of 10.

Given information-

The number whose value Bethany wants to estimate is,

\((4.296\times10^{11})(1.8614\times10^{-14})\)

Here the power of the 10 is 11 and -14 for the two number.

First solve the number without the multiple of 10 or the power of 10 is zero as,

\((4.296\times1.8614)(10^{11}\times10^{-14})\\8\times(10^{11}\times10^{-14})\)

The power of the two numbers with same base is added in the multiplication. thus,

\(8\times(10^{11-14})\)

The angle θ is maximized when c = 2 (halfway between two points).

The maximum angle at which a conveyor can be inclined while still delivering a predetermined amount of bulk material in a given amount of time. As the maximum angle is approached, the rate of bulk material handling is usually reduced.

Given that, in the figure, find the value of c in the interval [0, 4] on the x-axis that maximizes angle θ.

Express θ as a function of c, Let α be the angle to the left of θ and let β be the angle to the right, then,

tanα = 2/c

and tanβ = 2/(4-c)

At this point, we suppose that it might be easier to use cotangent in order to keep c inn numerator,

cotα = c/2

cotβ = (4-c)/2

We have, α+β+θ = π, so,

θ = π-α-β

= π-cot⁻¹c/2-cot⁻¹(4-c)/2

Differentiate, set equal to 0 and solve

dθ/dc = 1/1+(c/2)².1/2+1/1+(4-c/2)²(1/2)

Put dθ/dc = 0

1/1+(c/2)².1/2+1/1+(4-c/2)²(1/2) = 0

1/1+(c/2)²-1/1+(4-c/2)² = 0

1/1+(c/2)² = 1/1+(4-c/2)²

(4-c/2)² = (c/2)²

(c/2) = (4-c/2)

4-c = c

2c = 4

c = 2

Hence, The angle θ is maximized when c = 2 (halfway between two points).

The solution will provide the optimal Values for x41, x42, x43, x44, and x45 that maximize the objective function while satisfying the given constraints.

To optimize the variables x41, x42, x43, x44, and x45 subject to the given constraints, we can formulate it as a linear programming problem. The objective is to maximize the sum of the variables x41, x42, x43, x44, and x45. The constraints are that the variables x1, x2, x3, x4, x5 must equal 0, x21, x22, x23, x24, x25 must equal 4, and x31, x32, x33, x34, x35 must equal 0.

The linear programming problem can be written as follows:

Maximize: x41 + x42 + x43 + x44 + x45

Subject to:

x1 + x2 + x3 + x4 + x5 = 0

x21 + x22 + x23 + x24 + x25 = 4

x31 + x32 + x33 + x34 + x35 = 0

This is the Taylor polynomial of degree n = 4 for f(x) = sin(x) centered at a = π/6.

To approximate the function f(x) = sin(x) using a Taylor polynomial with degree n = 4 centered at a = π/6, we can use the Taylor series expansion of sin(x) around the point a.

The Taylor series expansion for sin(x) is given by:

sin(x) = sin(a) + cos(a)(x - a) - (1/2)sin(a)(x - a)^2 - (1/6)cos(a)(x - a)^3 + (1/24)sin(a)(x - a)^4 + ...

Plugging in the values a = π/6 and n = 4, we have:

sin(x) ≈ sin(π/6) + cos(π/6)(x - π/6) - (1/2)sin(π/6)(x - π/6)^2 - (1/6)cos(π/6)(x - π/6)^3 + (1/24)sin(π/6)(x - π/6)^4

Simplifying this expression, we have:

sin(x) ≈ 1/2 + √3/2(x - π/6) - (1/2)(x - π/6)^2 - (√3/6)(x - π/6)^3 + (1/24)(x - π/6)^4

b) the Cartesian coordinates of the point are (-4, 0).

c)  the Cartesian coordinates of the point are (sqrt(3), -1).

(a) To convert (2, 2 pi/3) from polar coordinates to Cartesian coordinates, we use the formulas x = r cos(theta) and y = r sin(theta):

x = 2 cos(2 pi/3) = -1

y = 2 sin(2 pi/3) = sqrt(3)

So the Cartesian coordinates of the point are (-1, sqrt(3)).

(b) To convert (4, 3 pi) from polar coordinates to Cartesian coordinates, we use the formulas x = r cos(theta) and y = r sin(theta):

x = 4 cos(3 pi) = -4

y = 4 sin(3 pi) = 0

So the Cartesian coordinates of the point are (-4, 0).

Step-by-step explanation:

Make use of the fact that for any \(a\) and \(b\):

\(\begin{aligned}& (a + b)\, (a - b) \\ =\; & a^{2} - a\, b + a\, b - b^{2} \\ =\; & a^{2} - b^{2}\end{aligned}\).

In other words, the difference \((a^{2} - b^{2})\) between two squares could be written as the product of \((a + b)\) and \((a - b)\).

Apply this identity to rewrite and simplify the expression in this question. In this example, \(a = 3\, y + 2\, z\) whereas \(b = 3\, y - 2\, z\).

the C-CAPM with power utility and lognormal consumption growth predicts that the representative agent in country A will consume more in the current period and that the price of an identical financial asset will be lower compared to country B.

The C-CAPM is a financial model that relates the consumption patterns and asset prices in an economy. In this scenario, the difference in subjective discount factors implies that the representative agent in country A values future consumption relatively less compared to country B. As a result, the representative agent in country A tends to consume more in the current period, prioritizing immediate consumption over saving for the future.

Furthermore, the C-CAPM suggests that the price of an identical financial asset, such as a stock or bond, will be lower in country A. This is because the higher subjective discount factor in country A implies a higher expected return requirement for investors. As a result, investors in country A will demand a higher risk premium, leading to a lower price for the financial asset.
