Answer:

150(2)^t

Step-by-step explanation:

The function that represents the worth, w(t), of the basketball at any given time, t, can be written as:

w(t) = 150(2)^t

where t is the number of years since the basketball was collected.

This function uses the formula for exponential growth, where the value of the basketball doubles each year. The initial value of the basketball is $150, and the value is multiplied by 2 for each year that passes. Therefore, after one year, the basketball is worth $300 (2 times $150), after two years it is worth $600 (2 times $300), and so on.

By plugging in different values of t, we can calculate the worth of the basketball at any given time.

Step-by-step explanation:

If you look at the graph of y = 16x^4 - 81, you see that it intersects the x-axis at two distinct places so there are two real solutions.  Whenever a polynomial function intersects the x-axis, there are at least one or more real roots.

I attached a picture of the graph using Desmos, where you'll see that there are two real roots.

To write the given quadratic equation, y = (x + 1)^2 - 4, in factored form, we can start by expanding the equation using the square of a binomial:

y = (x + 1)(x + 1) - 4

y = (x^2 + 2x + 1) - 4

y = x^2 + 2x + 1 - 4

y = x^2 + 2x - 3

Now, to find the zeros of the equation, we set y = 0 and solve for x:

x^2 + 2x - 3 = 0 To factor this quadratic equation, we need to find two numbers whose product is -3 and whose sum is 2. The numbers that satisfy this condition are 3 and -1:

(x + 3)(x - 1) = 0

Now, setting each factor equal to zero, we can find the values of x:

x + 3 = 0  =>  x = -3

x - 1 = 0  =>  x = 1

Therefore, the factored form of the equation y = (x + 1)^2 - 4 is (x + 3)(x - 1) = 0, and the zeros of the equation are x = -3 and x = 1.

First, we need to find the number of students who bring lunch:

1/3 x 36 = 12 students bring lunch.

Next, we need to find the number of students who order lunch:

So, the total number of students who eat lunch each day is:

12 (who bring lunch) + 6 (who order lunch) = 18 students.

So the frequency of individuals with red hair in population b after 10 generations of migration is approximately 0.02%.

We need to use the Hardy-Weinberg equation, which describes how the frequencies of alleles in a population will change over time.
The equation is:
p^2 + 2pq + q^2 = 1
Where:
p = frequency of one allele
q = frequency of the other allele
p^2 = frequency of homozygous dominant individuals
2pq = frequency of heterozygous individuals
q^2 = frequency of homozygous recessive individuals
In this case, the recessive trait is red hair, so we'll use q to represent the frequency of the recessive allele.
In population a, q = 0.49, so p (the frequency of the dominant allele) = 1 - q = 0.51.
In population b, q = 0.25, so p = 0.75.
After the emigrants from population a migrate to population b, the new frequency of the recessive allele in population b will be:
q' = (0.1 x 0.49) + (0.9 x 0.25) = 0.286
This is the new value of q after one generation of migration. To calculate the frequency of red-haired individuals after 10 generations, we need to use the equation:
q^10 = (0.286)^10 = 0.0002
So the frequency of individuals with red hair in population b after 10 generations of migration is approximately 0.02%.
The frequency of individuals with red hair in population b after 10 generations of migration is approximately 0.02%. This is based on the assumption that the emigrants from population a mate randomly with members of population b and that the population sizes remain constant over time.

Answer:

Step-by-step explanation:

To show that points C(-4, 3), A(6, 1), and T(2, -3) form a right-angled triangle, we can calculate the slopes of the lines connecting these points.

The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:

slope = (y2 - y1) / (x2 - x1)

Let's calculate the slopes of the lines formed by the points:

Slope of line CA:

m_CA = (1 - 3) / (6 - (-4))

= (-2) / 10

= -1/5

Slope of line CT:

m_CT = (-3 - 3) / (2 - (-4))

= (-6) / 6

= -1

Slope of line AT:

m_AT = (-3 - 1) / (2 - 6)

= (-4) / (-4)

= 1

Since two lines are perpendicular if and only if the product of their slopes is -1, we can check if the product of the slopes of CA and AT is -1. If it is, then the triangle formed by the points C, A, and T is a right-angled triangle.

Product of slopes m_CA and m_AT:

(-1/5) * (1) = -1/5

The product of the slopes is -1/5, which is not equal to -1. Therefore, the points C(-4, 3), A(6, 1), and T(2, -3) do not form a right-angled triangle.

Hence, we can conclude that the points C, A, and T do not form a right-angled triangle based on the slopes of the lines connecting them.

The expected value is 0.8, variance is 0.48, and standard deviation is 0.693 with the given probability.

a. The probability of getting one success in two trials with p=0.4 is given by the binomial probability formula:

f(1) = 2C1 * (0.4)^1 * (0.6)^1 = 0.48

b. The probability of getting zero successes is:

f(0) = 2C0 * (0.4)^0 * (0.6)^2 = 0.36

c. The probability of getting two successes is:

f(2) = 2C2 * (0.4)^2 * (0.6)^0 = 0.16

d. The probability of at least one success is:

P(at least one success) = 1 - P(no success)

= 1 - f(0)

= 1 - 0.36

= 0.64

e. The expected value of a binomial distribution with n trials and probability of success p is given by:

E(X) = np

In this case, n = 2 and p = 0.4, so:

E(X) = 2 * 0.4 = 0.8

The variance of a binomial distribution is given by:

Var(X) = np(1-p)

So:

Var(X) = 2 * 0.4 * 0.6 = 0.48

The standard deviation is the square root of the variance:

So the equation of the parabola in standard form is y = (5/4)x^2 - (7/4)x + 2.

One way to approach this problem is to use the standard form of the equation for a parabola, which is y = ax^2 + bx + c. We can set up a system of three equations using the three points given and solve for the coefficients a, b, and c.

Starting with the point (-2, 18):

18 = a(-2)^2 + b(-2) + c

18 = 4a - 2b + c

Using the point (0, 2):

2 = a(0)^2 + b(0) + c

2 = c

Using the point (4, 42):

42 = a(4)^2 + b(4) + c

42 = 16a + 4b + c

Substituting c = 2 into the second equation, we get:

2 = 2

This is always true, so it doesn't provide any additional information.

Substituting c = 2 into the first and third equations, we get:

18 = 4a - 2b + 2

42 = 16a + 4b + 2

Simplifying each equation:

9 = 2a - b

20 = 4a + b

Solving this system of equations, we get:

a = 5/4

b = -7/4

The answer is that there are 32 ways to place two indistinguishable kings on an empty chess board so that they do not attack each other.

To answer this question, we need to understand the basic rules of chess. A king can move one square in any direction, including diagonally. So, to ensure that two kings are not attacking each other, we need to place them on two squares that are not adjacent to each other, and not on the same diagonal line.
There are 64 squares on a chess board, and the first king can be placed on any of those squares. The second king, however, has fewer options because it cannot be placed on the same row, column or diagonal as the first king.
The number of ways to place the second king will depend on where the first king was placed. For example, if the first king was placed in one of the corners, then the second king will have only two possible squares to be placed in. On the other hand, if the first king was placed in the center of the board, then the second king will have fewer options.
Overall, there are 32 possible squares for the second king to be placed in, which means that there are 32 possible ways to place two indistinguishable kings on an empty chess board so that they do not attack each other.

However, there are two gods who are not given a place on the throne - Hades and Hestia.

Hades, the god of the underworld, is not included in the twelve thrones because he rules over the dead in the underworld. As a result, he does not need a place on Olympus. Hestia, the goddess of the hearth, voluntarily gave up her seat to Dionysus, as she preferred to live a peaceful and uneventful life on earth. She is regarded as one of the "lesser" gods but still holds great importance in Greek mythology, as she is responsible for the protection of the home and family.

Step-by-step explanation:

First, let's simplify the expression by combining like terms:

x - 7x^2 + 8 - x^2 - x + 6x^2 + 8

= -7x^2 + 5x^2 - x^2 + x + 16

= -x^2 + 2x + 16

Now we need to factor the quadratic expression -x^2 + 2x + 16. We can use the quadratic formula or complete the square to find the roots, but it turns out that the expression doesn't factor nicely. However, we can rewrite it as -(x^2 - 2x - 16) and then use the quadratic formula to find the roots of the expression inside the parentheses:

x = (-(-2) ± sqrt((-2)^2 - 4(-16)))/(2(1))

x = (2 ± sqrt(68))/2

x = 1 ± 2sqrt(17)/2

x = 1 ± sqrt(17)

So we have:

-x^2 + 2x + 16 = -(x - (1 + sqrt(17)))(x - (1 - sqrt(17)))

Therefore, the expression is equal to -x^2 + 2x + 16, which corresponds to the option:

Let's use x to represent the cost of one orange and y to represent the cost of one lemon. We can then set up a system of two equations:16x + 13y = 9.29 19x + 6y = 9.05 These equations represent the total cost of buying a certain number of oranges and lemons in two different scenarios.

To understand why we need two equations, let's consider the first equation: 16x + 13y = 9.29

This equation tells us that if we buy 16 oranges and 13 lemons, the total cost will be $9.29. But we don't know the individual prices of oranges and lemons yet. That's where the second equation comes in: 19x + 6y = 9.05

This equation tells us that if we buy 19 oranges and 6 lemons, the total cost will be $9.05. Again, we don't know the individual prices yet.

By setting up a system of equations, we can solve for x and y, which represent the prices of oranges and lemons, respectively.

One way to solve this system is by elimination. We can multiply the first equation by 19 and the second equation by -16, which will allow us to eliminate y:

304x + 247y = 176.51
-304x - 96y = -144.8

Adding these two equations together gives: 151y = 31.71
Dividing both sides by 151, we get: y = 0.21
Now we can substitute this value of y into one of the original equations to solve for x. Let's use the first equation:
16x + 13(0.21) = 9.29
16x + 2.73 = 9.29
16x = 6.56
x = 0.41

So the cost of one orange is $0.41 and the cost of one lemon is $0.21.

If A and B are mutually exclusive events, P(A ∩ B) = 0, and the general addition law can be simplified to the sum of the individual probabilities for A and B

Given data ,

If events A and B are mutually exclusive, it means that they cannot occur simultaneously. In this case, the intersection of events A and B, denoted as A ∩ B, would indeed have a probability of 0

And , P(A ∪ B) = P(A) + P(B)

Therefore , if A and B are mutually exclusive, the probability of either event A or event B occurring is equal to the sum of their individual probabilities.

Hence , the probability is solved

Answer:

x = -18.4

Step-by-step explanation:

3-8x=95-3x

add 3x to both sides

3-5x=95

subtract 3 from both sides

-5x=95-3

-5x=92

divide both sides by -5

x=-18.4
