What is an angle that is adjacent to ∠CED?

Answer: To find the time it takes Victoria to make one necklace, we can divide the total time by the number of necklaces she can make in that time. If it takes her 4 days to make 8 necklaces, it takes her 4/8 = 0.5 days to make one necklace.

Next, we can convert 0.5 days into hours to find the time it takes her to make one necklace. Since there are 24 hours in a day, it takes her 0.5 * 24 = 12 hours to make one necklace.

So, it takes Victoria 12 hours to make one necklace.

The number of euros with Richard in the beginning is 2.5 euros.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the money with Richard at the beginning be $x.

Richard gambled and doubled his money.

Now, the money is 2x.

He gave one euro to his friend and gambled again.

Here, 2x-1

This time he tripled his money.

So, the money is 3(2x-1)

After this he bought a hamburger for two euro.

Now, 6x-3-2

6x-5

Now he had four times the euros in his wallet that he gambled the first time.

Here, 6x-5=4x

6x-4x=5

2x=5

x=2.5

Therefore, the number of euros with Richard in the beginning is 2.5 euros.

The conversion of the units gives:

NUMBER 1: 75 mi/hr = 36.957 m/s

NUMBER 2: 5d = 432000 seconds

Unit conversion is the process of converting a quantity expressed in one unit of measurement to another unit of measurement. For example, converting a distance measured in meters to feet, or converting a weight measured in kilograms to pounds.

NUMBER 1

1 mile = 5820 feet, 1 feet = 0.3048 meter.

1 hour = 60 minutes = 60 * 60 seconds = 3600 seconds

To convert 75 mi/hr to m/s, we have:
75 mi/hr = (75 * 5820 * 0.3048)m / (60 * 60)s = 36.957 m/s

NUMBER 2

Since we have 24 hours in a day, 60 minutes in 1 hour and 60 seconds in a minute. Thus, 5 days can be written as:

5d = 5 * 24 * 60 * 60 = 432000 seconds

Answer:

17/30

Step-by-step explanation:

Number of students = 30

Number of girls and A students = 13+4 = 17

Probability of a student being chosen at random being either a girl or an A student = Total Number of girls and A students/Total No of students = 17/30

Probably of a student chosen at random being either a girl or an A student would be 17/30

The probability of choosing a girl or an A student is 17/30 or 0.567.

There are a couple of ways to approach this problem, but one common method is to use the formula:

                  P(girl or A) = P(girl) + P(A) - P(girl and A)

where P(girl) is the probability of choosing a girl, P(A) is the probability of choosing an A student, and P(girl and A) is the probability of choosing a student who is both a girl and an A student.

To calculate each of these probabilities, we first need to find the total number of girls and A students in the class:

                 Total number of girls: 13

                 Total number of A students: 4 boys + 5 girls = 9

Now we can calculate each probability:

                  P(girl) = number of girls / total number of students = 13 / 30

                  P(A) = number of A students / total number of students = 9 / 30

                  P(girl and A) = number of girls who made an A / total number of students = 5 / 30

Plugging in the values, we get:

                  P(girl or A) = P(girl) + P(A) - P(girl and A)

                  = 13/30 + 9/30 - 5/30

                  = 17/30

Therefore, the probability of choosing a girl or an A student at random from the class is 17/30, or about 0.567.

(b)  Choice A  - everywhere in (π/2, 3π/4)

(c) Choice A    - everywhere in (π/2, 3π/4)

Step-by-step explanation:

This can be answered by knowing that the interval (π/2, 3π/4) lies in the second quadrant which lies between π/2 and π

π/2 = 90° and 3π/4 = 135° which lies in the second quadrant

If an angle  θ lies in the first quadrant, we have the following facts:
sin(θ) is positive

cos(θ) is negative

tan(θ) = sin(θ)/cos(θ) is also negative (+ve divided by -ve is negative)

Therefore sin(t) is positive in the interval (π/2, 3π/4).
Correct choice is A

(b)

cos(t) is negative in the interval (π/2, 3π/4).
Choice A

(c) tan(t) is negative in the interval (π/2, 3π/4).
Choice A

Answer:

t=2

Step-by-step explanation:

We have the equation:

[tex]t+\frac{1}{4} = \frac{27}{12}[/tex]

And the main thing here is if we do one thing to an equation we do it to both sides. So if we subtract 1/4 from one side, we do it to both sides. If we subtract 1/4 from the left side it cancels out with the 1/4 leaving us just with the "t" unknown, giving us a solution:

[tex]t=\frac{27}{12} - \frac{1}{4}[/tex]

Now from here we can just multiply the 1/4 by 3/3 so we get the same denominator and combine them into one fraction:

[tex]t=\frac{27}{12} - \frac{3}{12}[/tex]

Now subtract the numerators:

[tex]t=\frac{24}{12}[/tex]

Simplify:

We compute the functions as follows

1. g(f(0)) = -3

2. f(f(2)) = 5

3. f(g(x)) = 6x - 1

4. g(h(x)) = 3x² + 3

5. g(f(x)) = 6x - 3

6.  f(f(x)) = 4x - 3

7. g(g(x)) = 9x

A function is a  mathematical equation that shows the relationship between two variables.

Given that

Let's compute the given functions.

To compute the function g(f(0)), we first compute g(f(x)).

So, g(f(x)) = 3f(x)

= 3(2x - 1)

= 6x - 3

So, g(f(0)) = 6(0) - 3

= 0 - 3

= -3

So, g(f(0)) = -3

To compute the function f(f(2)), we first compute f(f(x)).

So, f(f(x)) = 2(f(x)) - 1

= 2(2x - 1) - 1

= 4x - 2 - 1

= 4x - 3

So, f(f(2)) = 4(2) - 3

= 8 - 3

= 5

So, f(f(2)) = 5

To compute the function f(g(x)), since we have

So, f(g(x)) = 2(g(x)) - 1

= 2(3x) - 1

= 6x - 1

So, f(g(x)) = 6x - 1

To compute the function g(h(x)), Since

So, g(h(x)) = 3(h(x))

= 3(x² + 1)

= 3x² + 3

So, g(h(x)) = 3x² + 3

To compute the function g(f(x)), Since

So, g(f(x)) = 3(f(x))

= 3(2x - 1)

= 6x - 3

So, g(f(x)) = 6x - 3

To compute the function f(f(x)), Since f(x) = 2x - 1,

So, f(f(x)) = 2(f(x)) - 1

= 2(2x - 1) - 1

= 4x - 2 - 1

= 4x - 3

So, f(f(x)) = 4x - 3

To compute the function g(g(x)), Since g(x) = 3x

So, g(g(x)) = 3(g(x))

= 3(3x)

= 9x

So, g(g(x)) = 9x

A. To find the profit-maximizing level of price and output, we need to find the equilibrium point where the marginal revenue equals marginal cost.

The marginal cost of production is the derivative of the total cost function: MC = dC/dQ = 3.

The marginal revenue is the derivative of the inverse demand function: MR = dP/dQ = -1.

So at the profit-maximizing level of output, MC = MR.

3 = -1

Q = 6

Then we can substitute Q = 6 back into the inverse demand function to find the price:

P (Q) = 12 - Q

P (6) = 12 - 6

P = 6

So the profit-maximizing level of output is 6 units at a price of $6.

B. To find the maximum profit of the firm, we need to calculate the total revenue and the total cost at the profit-maximizing level of output.

The total revenue is the product of the price and the quantity:

TR = P * Q

TR = 6 * 6

TR = 36

The total cost is given by the total cost function:

TC = C (Q)

TC = 3 * Q

TC = 3 * 6

TC = 18

So the maximum profit is the difference between the total revenue and the total cost:

Profit = TR - TC

Profit = 36 - 18

Profit = 18

The maximum profit of the firm is $18 at an equilibrium price level of $6 and an output level of 6 units.

Answer: The equation that can be solved for t to find the time (in seconds) when the diver hits the water is:

h(t) = 25 - 16e^(-ft) = 0

Where h(t) is the height of the diver in feet at time t, and f is a positive constant related to the speed of the fall.

To find the time when the diver hits the water, we set h(t) equal to zero and solve for t. This gives us the time when the height of the diver is equal to the water surface.

25 - 16e^(-ft) = 0

25 = 16e^(-ft)

e^(-ft) = 25/16

-ft = ln(25/16)

t = -ln(25/16)/f

Note that the negative sign in the equation for t indicates that the time is counted from the moment the diver starts falling. The constant f can be determined from the physical characteristics of the diver and the conditions of the fall, but it is not necessary to know the exact value of f to find the time when the diver hits the water.

Let x be the cost of the bench. Then the cost of the garden table is 3x.

The combined cost of the bench and the table is 1000, so x + 3x = 1000.

Combining like terms, we get 4x = 1000.

Dividing both sides by 4, we get x = 250.

The cost of the bench is 250.

Answer:

250.

Step-by-step explanation:

Let's call the cost of the bench "x".

The cost of the garden table is then 3x.

So the combined cost of both is x + 3x = 4x = 1000

So x = 250, and the cost of the bench is 250.

The expected value of x is (m+1)/2, and m must be a positive integer.

The expected value of x is the average value of x that we would expect to get if we selected an integer from the set {1, 2, ..., m} many times. To find the expected value of x, we multiply each possible value of x by its probability of being selected and then sum these products. In this case, each integer in the set {1, 2, ..., m} has an equal probability of being selected, so the expected value is (1 + 2 + ... + m) / m = (m(m+1)) / 2m = (m+1) / 2.

The number of ways to choose 3 students out of 10 to come in first, second, and third place in a spelling contest, with no ties, is calculated using the combination formula. The combination formula is:

C(n, r) = n! / (r! (n-r)!)

Where n is the total number of items, and r is the number of items to choose. In this case, n = 10 and r = 3.

So, the number of ways to choose 3 students out of 10 is:

C(10, 3) = 10! / (3! (10-3)!) = 10! / (3! 7!) = 10 x 9 x 8 / (3 x 2 x 1) = 120.

Therefore, there are 120 different ways to choose 3 students out of 10 to come in first, second, and third place in a spelling contest, with no ties.
