Cone Surface Area Calculation

surface area of cone slant height is 2 radius is 1

To find the surface area of a cone, we need to know the radius and slant height of the cone.

In this case, we are given that the radius (r) is 1, and the slant height (l) is 2. We can use the Pythagorean theorem to find the height (h) of the cone:

l^2 = r^2 + h^2

2^2 = 1^2 + h^2

4 = 1 + h^2

h^2 = 3

h = sqrt(3)

Now we can use the formula for the surface area of a cone:

A = πr^2 + πrl

Substituting the values we know:

A = π(1)^2 + π(1)(2)

A = π + 2π

A = 3π

So the surface area of the cone is 3π

Answer:8%

Step-by-step explanation:Since the cards are put back after each pick, the two picks are independent events.

The probability of picking a 4 on the first pick is 1/5, as there is one card with a value of 4 out of five cards in total.

The probability of picking a number greater than 4 on the second pick is 2/5, as there are two cards with values greater than 4 (5 and 6) out of five cards in total.

The probability of both events occurring (picking a 4 and then a number greater than 4) is the product of the probabilities of each event:

1/5 x 2/5 = 2/25

So the probability of picking a 4 and then picking a number greater than 4 is 2/25.

To express this as a percentage, we can multiply by 100:

2/25 x 100 = 8%

Therefore, the probability of picking a 4 and then picking a number greater than 4 is 8%.

Shirley's water bottle holds 4 quarts when it is half full.

Step-by-Step-Explanation

If the second bottle is one-third full and holds 2 quarts, then it means that it can hold a total of 2 / (1/3) = 6 quarts when completely full.

Let's call the amount of water in Shirley's bottle "x" quarts. We know that when she pours it into the second bottle, it becomes completely full with 6 quarts. So we can set up the equation:

x + 2 = 6

Solving for x, we get:

x = 6 - 2

The sum of the first 8 terms of the sequence is 720.

A sequence is a set of numbers that are arranged in a specific order, according to some rule or pattern. Each number in the sequence is called a term, and the position of the term in the sequence is called its index or subscript. Sequences can be either finite or infinite.

We can see that this is an arithmetic sequence with a first term a = 27 and a common difference d = 18. To find the sum of the first 8 terms of the sequence, we can use the formula for the sum of an arithmetic sequence:

Sn = n/2[2a + (n-1)d]

where Sn is the sum of the first n terms, a is the first term, d is the common difference, and n is the number of terms.

Plugging in the values we know, we get:

S8 = 8/2[2(27) + (8-1)(18)]

= 4[54 + 126]

= 4(180)

= 720

Therefore, the sum of the first 8 terms of the sequence is 720.

The probability that ht/th occurs before hh, given that the first coin toss is H or T, is 1/4.

To find the probability that ht/th occurs before hh, by conditioning on the first coin toss is as follows: The sample space can be represented as T or H. 1) If the first toss is a T, then the following toss should be an H to obtain the sequence ht, which is what we want. The probability of this event is 1/2. If the second toss is T, we get the sequence tt, and the process repeats.

2) If the first toss is an H, then we need to obtain the sequence th. The probability of this event is 1/2. If we obtain the sequence hh, the process repeats. We now have two cases that must be considered: case 1: If the first toss is a tail, then the probability that ht occurs before hh can be calculated as follows:

P(ht occurs before hh|first toss is a T) = P(ht occurs before hh|TT)P(TT)+ P(ht occurs before hh|HT)P(HT)= 0 * 1/4 + (1/2) * 1/2= 1/4Therefore, the probability of ht occurring before hh, given that the first toss is a T, is 1/4. case 2: If the first toss is an H, then the probability that ht occurs before hh can be calculated as follows:

P(ht occurs before hh|first toss is an H) = P(ht occurs before hh|TH)P(TH)+ P(ht occurs before hh|HH)P(HH)= (1/2) * 1/2 + 0 * 1/2= 1/4Therefore, the probability of ht occurring before hh, given that the first toss is an H, is 1/4. Therefore, the probability that ht occurs before hh, given that the first coin toss is H or T, is 1/4.

By looking at the logistic model of US population, it can be said that the population will exceed 600 million by the year 2148.

(a) The logistic model for the US population is given by P(t) = (C/1 + Ae^(-kt)), where C is the carrying capacity, A is a constant, k is a constant, and t is time. Given that the carrying capacity for the US population is 800 million and the population was 282 million in 2000, we can formulate the logistic model as follows:

P(t) = (800/1 + Ae^(-kt))

To find the value of A, we can plug in the initial conditions. Let t = 0 correspond to the year 2000 and P(0) = 282:

282 = (800/1 + Ae^(0))
282 = (800/A + 1)
A = (800/282) - 1
A = 1.84

Therefore, the logistic model for the US population is:

P(t) = (800/1 + 1.84e^(-kt))

(b) To determine the value of k in the model, we can use the fact that the population in 2010 was 309 million. Let t = 10 correspond to the year 2010 and P(10) = 309:

309 = (800/1 + 1.84e^(-10k))
1.84e^(-10k) = (800/309) - 1
e^(-10k) = 0.593/1.84
-10k = ln(0.593/1.84)
k = -0.076

Therefore, the value of k in the model is k = -0.076.

(c) To predict the US population in the years 2100 and 2300, we can plug in the values of t = 100 and t = 300 into the model:

P(100) = (800/1 + 1.84e^(-100(-0.076))) = 535.7 million
P(300) = (800/1 + 1.84e^(-300(-0.076))) = 762.2 million

Therefore, the predicted US population in the year 2100 is 535.7 million and in the year 2300 is 762.2 million.

(d) To predict the year in which the US population will exceed 600 million, we can set P(t) > 600 and solve for t:

(800/1 + 1.84e^(-kt)) > 600
1.84e^(-kt) < (800/600) - 1
e^(-kt) < 0.333/1.84
-kt < ln(0.333/1.84)
t > -ln(0.333/1.84)/k

Using the value of k from part (b), we get:

t > -ln(0.333/1.84)/(-0.076) = 147.7

Therefore, the population of US will exceed 600 million by the year 2148.

Answer:  C $462.50

Step-by-step explanation:

It's $462.50 because since $6 has a higher profit you would want to try and sell more of that product (The football). So $6 times 45 is 270. And the max number of balls the store can have is 80, 80 minus 45 is 35 so there can only 35 baseballs left. 35 times $5.50 is 192.50. Lastly, you add the two products, and you get 462.50.

The maximum profit the store can make from selling footballs and baseballs in a typical month is $462.50.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example: so

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let's say the store sells x footballs and y baseballs.

The total number of balls sold can be expressed as x + y ≤ 80.

Also, we know that 35 ≤ x ≤ 45 and 40 ≤ y ≤ 55.

To maximize the profit, the store should sell the maximum number of footballs and baseballs that it can stock.

From the constraints, we see that the maximum number of footballs the store can sell is 45 and the maximum number of baseballs it can sell is 55, which together make a total of 100 balls.

However, this exceeds the 80-ball limit, so we need to adjust the numbers.

Let's say the store sells 45 footballs and y baseballs.

Then, y ≤ 35 since 45 + 35 = 80, which is the maximum number of balls the store can stock.

Similarly, let's say the store sells x footballs and 55 baseballs.

Then, x ≤ 25 since 25 + 55 = 80.

To find the maximum profit, we need to calculate the profit from selling 45 footballs and 35 baseballs, which will give the highest profit among the feasible combinations.

The profit from selling 45 footballs is 45 × $6 = $270.

The profit from selling 35 baseballs is 35 × $5.50 = $192.50.

The total profit is $270 + $192.50 = $462.50.

Therefore,

The maximum profit the store can make from selling footballs and baseballs in a typical month is $462.50.

Answer:

We can start by simplifying both sides of the equation:

5x² + 18x = 25x + 15 + 3x²

2x² - 7x - 15 = 0

Now we need to factor this quadratic equation:

2x² - 7x - 15 = (2x + 3)(x - 5)

Setting each factor equal to zero gives us the solutions:

2x + 3 = 0 or x - 5 = 0

Solving for x, we get:

x = -3/2 or x = 5

Therefore, the solutions to the quadratic equation are x = -3/2 and x = 5.

So, the correct answer is (x - 5)(2x+3).

Step-by-step explanation:

If we let x be the number of attendees last year then since this year's attendees 270 is 125% of x we get

125% of x = 270

125% as a decimal = 125/100 = 1.25

So we get the equation
1.25x = 270

Divide by 1.25 to get

1.25x/1.25 = 270/1.25

x = 216

So there were a total of 216 attendees last year

25% of last year attendees = 0.25 x 216 = 54

Finding the area of the circle of spilled juice as a function of time is: j(t) = πr(t)²

An equation is mathematical statement that asserts  equality of two expressions. It contains one or more variables, and typically consists of terms on either side of equals sign.

Part A:

Let the radius of the circular pattern be r at time t. Then, we have:

j = πr²

Taking the derivative of both sides with respect to time, we get:

dj/dt = 2πr(dr/dt)

Since the rate of change of the radius is unknown, we can express it in terms of the rate of change of j:

dr/dt = (1/2πr)(dj/dt)

Substituting this expression for dr/dt back into our original equation, we get:

j = πr²

dj/dt = π(2r)(dr/dt)

dj/dt = 2πr(dr/dt)

dj/dt = 2πr(1/2πr)(dj/dt)

dj/dt = dj/dt

Therefore, the area of the spilled juice as a function of time is:

j(t) = πr(t)²

Part B:

If we assume that the rate of change of the radius is constant over the first 2 minutes, we can use the formula for the area of a circle to find the area of the spilled juice after 2 minutes:

j(2) = πr(2)²

To flesh out a coordinate descent method : (i) One common approach is to choose coordinate with the largest gradient. (ii) One common approach is to use a line search, where we try out step sizes along the chosen coordinate and select the one that leads to the largest decrease in the function value. (iii) One common stopping criterion is to stop when the change in function value.

This can be done by computing the partial derivatives of the function with respect to each coordinate, and selecting the one with the largest absolute value. This approach is known as "greedy" coordinate descent, and it can help speed up convergence by focusing on the most important directions.

This approach can be more computationally efficient, since it doesn't require computing the gradient at each step. Another approach is to use a fixed step size, which can be simpler to implement but may not always lead to the best results.

By choosing the coordinate to optimize along, determining the step size, and setting a stopping criterion, we can develop a coordinate descent method that is well-suited to our particular optimization problem.

Using the system of equations, we found that :

plane speed = 267.00 mph; wind speed = 27.00 mph

What is meant by an equation?

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero. As we can balance this by deducting the right-side expression from both sides' expressions, this won't reduce the generality.

The distance travelled =  1176.00 miles

Time taken = 4 hours and 54 minutes = 4*60 + 54 = 294 minutes

The times taken for return flight = 4 hours = 240 minutes

Let,

x = speed of the plane

y = speed of the wind

In a headwind the speed reduces.

So the relative speed of the plane is (x-y)

distance = speed * time

1176 = (x-y) * 294

x-y = 4

Now for the return flight, the wind is tailwind and the speed increases.

So the relative speed of the plane is (x+y).

1176 = (x+y) * 240

x + y = 4.9

Now we have a system of equations.

x - y = 4

x + y = 4.9

Adding,

2x = 8.9

x  = 4.45 miles/min = 4.45 * 60 miles/hour = 267 miles/hour

and

y = 4.9 - x = 4.9 - 4.45 = 0.45 miles/min = 0.45*60 = 27 miles/hour

Therefore using the system of equations, we found that :

plane speed = 267.00 mph; wind speed = 27.00 mph

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

The function g(x) is given as g(x) = 4x - 1.

The function f(x) is given as f(x) = x + 3.

To find (g o f)(x/2), we need to first find f(x/2) and then substitute this value into g(x) in place of x.

f(x) = x + 3

So, f(x/2) = (x/2) + 3

Now, substitute this into the equation of g(x) in place of x -

g(x) = 4x - 1

g(f(x/2)) = 4(f(x/2)) - 1

= 4((x/2) + 3) - 1 (substituting f(x/2))
