You Dont Have To Answer Both Of 3 And 4 You Can Answer One If You'd Like.

Answers

Answer 1

Answer:

below

Step-by-step explanation:

3. 2x² - 2x + 9 = y

a) The equation of the axis of symmetry is x = 0.5 (since it's the x-coordinate of the vertex)

b) To find the vertex, we need to complete the square:

2x² - 2x + 9 = y

2(x² - x) + 9 = y

2(x² - x + 1/4) + 9 - 2(1/4) = y

2(x - 1/2)² + 8.5 = y

So the vertex is at (0.5, 8.5).

c) The parabola opens up since the coefficient of x² is positive.

d) The vertex is the minimum point.


4. -x² + 10x = y

a) The equation of the axis of symmetry is x = 5 (since it's the x-coordinate of the vertex).

b) To find the vertex, we need to complete the square:

-x² + 10x = y

-(x² - 10x) = y

-(x² - 10x + 25 - 25) = y

-(x - 5)² + 25 = y

So the vertex is at (5, 25).

c) The parabola opens down since the coefficient of x² is negative.

d) The vertex is the maximum point.

. Liliana is renting a beach house for a family vacation. The house charges a $75 cleaning fee plus $95 per night. If Liliana wants to spend a maximum of $645 on the rental, which inequality represents “n”, the number of nights can she afford to rent the beach house?

Answers

Answer:

6 nights

Step-by-step explanation:

Set up your equation:

645=95n+75

then subtract the cleaning fee from the total to remove it from both sides

570=95n

then divid the remaining budget by the $95 per night charge

570/95= n =6

Meaning that she can afford 6 nights in the beach house at that price

Suppose you have a collection of coins, and each coin is either a nickel (worth 5s) or a dime (worth 10k ) or a quarter (worth 25s) You know that (i) you have 4 times more dimes than nickels (ii) you have 18 coins in total and (iii) altogether the coins are worth 290 e How many of each type of coin do you have? I have nickels and dimes and Ifntoraininteaer on diacimain number [more..]

Answers

Substituting these values back into equation (i), we get D = 4(3) = 12. There are 3 nickels, 12 dimes, and 3 quarters in the collection.

Let's assume the number of nickels is N, the number of dimes is D, and the number of quarters is Q. From the given information, we can deduce three equations:

(i) D = 4N (since there are 4 times more dimes than nickels),

(ii) N + D + Q = 18 (since there are 18 coins in total), and

(iii) 5N + 10D + 25Q = 290 (since the total value of the coins is 290 cents or $2.90).

To solve these equations, we can substitute the value of D from equation (i) into equations (ii) and (iii).

Substituting D = 4N into equation (ii), we get N + 4N + Q = 18, which simplifies to 5N + Q = 18.

Substituting D = 4N into equation (iii), we get 5N + 10(4N) + 25Q = 290, which simplifies to 45N + 25Q = 290.

Now we have a system of two equations with two variables (N and Q). By solving these equations simultaneously, we find N = 3 and Q = 3.

Substituting these values back into equation (i), we get D = 4(3) = 12.

Therefore, there are 3 nickels, 12 dimes, and 3 quarters in the collection.

A researcher wishes to estimate the population proportion of adults who are confident in the U.S. banking system. He wishes to estimate the proportion to within 5% with 95% confidence. How many adults should be included in the sample? A. 384 B. 385 C. 73 D. 1537 E.

Answers

Rounding up to the nearest whole number, the sample size needed is approximately 385. Therefore, the correct answer is B.

To determine the sample size needed to estimate a population proportion with a desired level of confidence and margin of error, we can use the formula:

n = (Z^2 * p * (1-p)) / E^2

Where:

n = sample size

Z = Z-score corresponding to the desired level of confidence (in this case, 95% confidence corresponds to a Z-score of approximately 1.96)

p = estimated proportion of adults confident in the U.S. banking system (unknown, but we can assume 0.5 to be conservative)

E = margin of error (5% expressed as a decimal, so E = 0.05)

Using these values, we can calculate the sample size:

n = (1.96^2 * 0.5 * (1-0.5)) / 0.05^2

n ≈ 384.16

(01.06) Below are two different functions, f(x) and g(x). What can be determined about their slopes? f(x)= 3x − 3 The function g(x) going through 0, 2 and 1, 5 (1 point) The function f(x) has a larger slope. The function g(x) has a larger slope. They both have the same slope. The relationship between slopes cannot be determined.

Answers

Answer:

They both have the same slope

Step-by-step explanation:

The standard equation of a given line is expressed as y = mx+c where m is the slope and c is the intercept.

given the function f(x)= 3x − 3, comparing this equation with the standard format, we will have;

mx = 3x

Divide through by x

mx/x = 3x/x

m = 3

Hence the slope of the function f(x)= 3x − 3 is 3.

For a function g(x) passing through the points (0, 2) and (1, 5), to determine the slope, we will use the formula for calculating slope expressed as;

m = Δy/Δx = y₂-y₁/x₂-x₁

From the coordinates, x₁ = 0, y₁ = 2, x₂ = 1, y₂ = 5

m = 5-2/1-0

m = 3/1 = 3

Hence the slope of g(x) passing through the points (0, 2) and (1, 5) is also 3.

This shows that both functions have the same slope.

Find the exact values of the remaining five trigonometric functions given the values for the sixth. Let sinθ=32,cosθ<0.

Answers

The exact values of the remaining five trigonometric functions are as follows:

1. cosθ = -√(-1023)

2. tanθ = 32/(-√(-1023))

3. secθ = 1/(-√(-1023))

4. cscθ = 1/32

5. cotθ = (-√(-1023))/32

Given that sinθ = 32 and cosθ < 0, we can use the Pythagorean identity to find the value of cosθ:

\(cos^2\)θ = 1 - \(sin^2\)θ

\(cos^2\)θ = 1 - \((32/1)^2\)

\(cos^2\)θ = 1 - 1024

\(cos^2\)θ = -1023

Since cosθ < 0, we take the negative square root:

cosθ = -√(-1023)

Now, we can find the remaining trigonometric functions:

1. cosθ: We already found that cosθ = -√(-1023).

2. tanθ: tanθ = sinθ/cosθ

tanθ = 32/(-√(-1023))

3. secθ: secθ = 1/cosθ

secθ = 1/(-√(-1023))

4. cscθ: cscθ = 1/sinθ

cscθ = 1/32

5. cotθ: cotθ = 1/tanθ

cotθ = (-√(-1023))/32

Therefore, the exact values of the remaining five trigonometric functions are as follows:

1. cosθ = -√(-1023)

2. tanθ = 32/(-√(-1023))

3. secθ = 1/(-√(-1023))

4. cscθ = 1/32

5. cotθ = (-√(-1023))/32

Note: The value of √(-1023) is an imaginary number, so the exact values of the trigonometric functions involve complex numbers.

Answer:

184

Step-by-step explanation:

First, note that the sides that are opposite to each other are congruent (this will come into play in a second). We can find the area of each triangle by doing 0.5(b)(h) (aka half * base* height). Since we've established tha opposite sides are congruent and the triangles are opposite to each other, they must be congruent. That means that the area is going to be the exact same for both triangles. So, we get the expression (0.5)(6)(4)(2), which comes out to 6*4 = 24. Then, to find the area of the 2 rectangles that are the sides, just do 5*10*2 = 100 square meters for both rectangles combines. Lastly, we need to find the area of the floor. The dimensions of the floor are 6 and 10, so we just do 6*10 = 60. Now, add all those numbers together. We get 100+60+24 = 184. Hope this helps! Let me know if anything is still confusing.

what is logistic growth function with oscillation?

Answers

Logistic growth function with oscillation is a mathematical model that describes the growth of a population that is limited by its resources.

The logistic growth function itself is an S-shaped curve that levels off as the population approaches its carrying capacity. However, when there are additional factors that cause oscillations or fluctuations in the population size, the model can be modified to include periodic behavior.

One example of a logistic growth function with oscillation is the Lotka-Volterra predator-prey model. In this model, the population of predators and prey are linked through a set of differential equations that describe how the two populations interact with each other. The oscillations in this model occur due to the interplay between the predator and prey populations, with each population affecting the growth of the other.

6c-8-2c=-16+c what’s the value of c

Answers

Answer:

The correct answer is c = -8/3.

Step-by-step explanation:

The first step in solving this problem would be to simplify by combining like terms on the left side of the equation.

6c - 8 - 2c = -16 + c

4c - 8 = -16 + c

Then, we can subtract c from both sides of the equation to get rid of the positive c on the right side of the equation.

4c - c - 8 = -16 + c - c

3c - 8 = -16

Next, we can add 8 to both sides of the equation.

3c - 8 + 8 = -16 + 8

3c = - 8

Then, we can divide both sides of the equation by 3.

c = -8/3

Net Present Value
A project has estimated annual net cash flows of $15,000 for ten
years and is estimated to cost $47,500. Assume a minimum acceptable
rate of return of 20%. Use

Answers

The required rate of return (or minimum acceptable rate of return) is 20 percent. If the net cash flows are $15,000 per year for ten years, the total cash flow is $150,000. The project's cost is $47,500. We can now apply the net present value formula to determine whether or not the project is feasible.

Net Present Value (NPV) = Cash flow / (1 + r)^n - Cost Where, r is the discount rate, n is the number of years, and Cost is the initial outlay.

Net Present Value = 150000 / (1 + 0.20)^10 - 47500

Net Present Value = $67,482.22

Since the NPV is positive, the project is feasible. When calculating net present value, it's important to remember that a positive NPV implies that the project is expected to generate a return that exceeds the cost of capital, whereas a negative NPV indicates that the project is expected to generate a return that is less than the cost of capital, and as a result, it should be avoided.

a circle is inscribed in a unit square. a smaller square is then inscribed within the circle. what is the side length of the smaller square?

Answers

To solve this problem, we need to use some basic geometry concepts. First, we know that the diagonal of a unit square is the square root of 2, since the sides are of length 1.  The side length of the smaller square inscribed within a circle inscribed in a unit square is 1.

Next, we know that the circle inscribed in the square will have a diameter equal to the diagonal of the square, which is the square root of 2. The radius of the circle will therefore be half of the diameter, which is sqrt(2)/2.
Now we can use the radius of the circle to find the side length of the smaller square inscribed within it. If we draw the diagonal of the smaller square, it will be twice the radius of the circle, or sqrt(2). This is because the diagonal of the square passes through the center of the circle and therefore has a length equal to twice the radius.
We can then use the Pythagorean theorem to find the length of each side of the smaller square. If we let x be the side length of the smaller square, then we have:
x^2 + x^2 = 2
2x^2 = 2
x^2 = 1
x = 1
Therefore, the side length of the smaller square is 1, which makes sense since it is inscribed within a unit square.

find the zeros and their multiplicities. consider using descartes' rule of signs and the upper and lower bound theorem to limit your search for rational zeros. write numbers as integers or simplified fractions.

Answers

The zeros of the polynomial are: x = 1/2 (with multiplicity 1), x = 3 (with multiplicity 1), and x = 5/2 (with multiplicity 1).We have found all three real zeros of the polynomial, which confirms that there are no complex zeros.

f(x) = 2x³ - 112x² + 27x - 41x + 15

To find the zeros and their multiplicities of this polynomial, we can begin by using Descartes' Rule of Signs. Let's consider the sign changes in the coefficients:

There are 2 sign changes in the coefficients (from 2x³ to -112x² and then to 27x, and finally to -41x and 15), which means there are either 2 or 0 positive real zeros.

There are no sign changes when we replace x with -x, which means there are either 0 or 2 negative real zeros.

Thus, there can be either 0, 2, or 4 real zeros, but we cannot determine their exact number or location with Descartes' Rule of Signs alone.

Next, we can use the Upper and Lower Bound Theorem to limit our search for rational zeros. According to this theorem, any rational zero of the polynomial must be of the form p/q, where p is a factor of the constant term (15 in this case) and q is a factor of the leading coefficient (2 in this case). Therefore, the possible rational zeros of the polynomial are:

±1/2, ±1, ±3/2, ±5, ±15/2, ±30

We can use synthetic division or long division to check these possible rational zeros and see which ones are actually zeros of the polynomial. Doing so, we find that the rational zeros of the polynomial are:

x = 1/2 (with multiplicity 1), x = 3 (with multiplicity 1), and x = 5/2 (with multiplicity 1).
