The cone pictured has a surface area of ______ square centimeters. (Use 3.14 for π.)

Answers

Assuming that the units are in cm
Given,

Diameter of the cone = 12 cm


Using the above, the radius of the cone can be determined, which is half the diameter of the cone

∴ Radius of the cone (r) = 12/2 = 6 cm
Height of the cone (h) = 7 cm

Using the above, slant height (s) = √(r² + h²) = √(6² + 7²) = √36 + 49 = √85 = 9.22 cm

π = 3.14

Now using the above values, we can calculate the total surface area of the cone.
Total surface area of the cone (A) = Lateral surface area of the cone (L) + Base surface area of the cone (B)

Lateral surface area of the cone (L) = π r s = 3.14 x 6 x 9.22 = 173.70 cm²
Base surface area of the cone (B) = π r² = 3.14 x 6² = 113.04 cm²

Total surface area of the cone = L + B = 173.70 + 113.04 = 286.74 cm²

Let h(x)=xg(x), where g(x)=the inverse of f(x). Find h'(5) using the chart.....(type that in a minute) ...?

Answers


h(x) = x g(x)
h'(x) = x g'(x) + (1)g(x)
h'(x) = x g'(x) + g(x)

Since g(x) = f^-1(x), then
g'(x) = 1/f'(x)

h'(x) = x/f'(x) + f^-1(x)
Therefore,
h'(5) = 5/f'(5) + f^-1(5).

Then, an interval of 68% is narrower than 90%, which is narrower than 95%, which is narrower than 98%.

The only option of the list that is right is the second one.

Answer: the 90% confidence interval is narrower than the 95% confidence interval.


why wouldn't the man stand in line to step on the scale ?

answer ?

Answers

Final answer:

The man wouldn't stand in line to step on the scale because the scale measures weight, not mass. When you stand on a bathroom scale, it measures the force exerted on it due to your weight. Weight is the force of gravity acting on an object, while mass is the amount of matter in an object.

Explanation:

The man wouldn't stand in line to step on the scale because the scale measures weight, not mass. When you stand on a bathroom scale, it measures the force exerted on it due to your weight. Weight is the force of gravity acting on an object, while mass is the amount of matter in an object. So, if the man were on the Moon or in an elevator accelerating, the scale reading would be different because the force of gravity on him would be different, but his mass would remain the same.

11-8 The Choi Company's next expected dividend, D1, is $3.18; its growth rate is 6 percent; and its stock currently sells for $36. New stock can be sold to net the firm $32.4 per share.

a. What is Choi's percentage flotation cost, F?

b. What is Choi's cost of new common stock, Re ?

Answers

Final answer:

Choi's percentage flotation cost is 10%, and the cost of new common stock is 15.81%, calculated using the difference in current stock price and net price per share for the flotation cost, and the dividend discount model for the cost of new common stock.

Explanation:

Calculating Choi's Flotation Cost and Cost of New Common Stock

The percentage flotation cost of Choi Company's new stock is 90.28% and the cost of new common stock is 15.94%.

To calculate Choi's percentage flotation cost (F), we start by looking at the difference between the price the stock currently sells for and the net amount the firm receives when selling new stock. The current stock price is $36, and the firm can net $32.4 per share from selling new stock, so the flotation cost per share is $36 - $32.4 = $3.6 per share. To find the percentage flotation cost, we divide this amount by the market price of the stock:

F = Flotation cost per share / Current stock price = $3.6 / $36 = 0.10 or 10%

Next, to calculate Choi's cost of new common stock (Re), we use the dividend discount model (DDM), which claims that the price of a stock is the present value of all future dividends. The expected dividend, D1, is $3.18 and the growth rate, g, is 6%. The cost of new common stock, taking into account the flotation cost, is calculated using the formula:

Re = (D1 / Net price per share) + g = ($3.18 / $32.4) + 0.06 = 0.0981 + 0.06 = 0.1581 or 15.81%

the principal will randomly choose 6 students from a large school to represent the school in a newspaper photograph. the probability that a chose student is an athlete is 30%. (assume that this doesn't change) What is the probability that 4 athletes are chosen? ...?

Answers


This is a binomial distribution. The probability of a binomial distribution is given by

P = nCr * p^r * q^(n-r)

For this problem,
n = 6
r = 4
p = 0.30
q = 0.70

P = 6C4 * 0.30^4 * 0.70^(6-4)
P = 5.95%
Final answer:

To find the probability of choosing exactly 4 athletes from 6 students when the chance of any student being an athlete is 30%, we use the binomial probability formula considering a fixed number of trials, a binary outcome, a constant probability, and independent trials.

Explanation:

The question asks about the probability of choosing 4 athletes out of 6 students from a school, given that each student has a 30% chance of being an athlete. We can treat this as a binomial probability problem because we have a fixed number of trials (six students chosen), two possible outcomes (athlete or not), a constant probability of success (30% chance the student is an athlete), and independence between trials.

To calculate the probability of exactly 4 athletes being chosen, we use the binomial probability formula:

P(X = k) = C(n, k) * [tex]p^k[/tex] * [tex](1-p)^(n-k)[/tex]

Where:

n is the number of trials (6 students)k is the number of successful trials (4 athletes)p is the probability of success on a single trial (30% or 0.3)C(n, k) is the combination of n items taken k at a time

Using these values, we find the probability that 4 out of 6 students chosen are athletes.

Farmer Ed has 7000 meters of fencing and wants to enclose a rectangular plot that borders on a river. If farmer Ed does not fence the side along the river, what is the largest are that can be enclosed? ...?

Answers

Let

x--------> the length side of the rectangular plot (assume side along the river)

y------> the width side of the rectangular plot

we know that

the perimeter of the rectangular plot is equal to

[tex]P=x+2y[/tex]

[tex]P=7,000\ m[/tex]

so

[tex]7,000=x+2y[/tex]

Clear variable y

[tex]y=(7,000-x)/2[/tex] -------> equation [tex]1[/tex]

The area of the rectangular plot is

[tex]A=x*y[/tex] ------> equation [tex]2[/tex]

substitute equation [tex]1[/tex] in equation [tex]2[/tex]

[tex]A=x*[(7,000-x)/2][/tex]

[tex]A=x*[(7,000-x)/2]\\\\ A=3,500x-0.5x^{2}[/tex]

we know that

To find the larger area that can be enclosed------> Find the vertex of the quadratic equation

The quadratic equation is a vertical parabola open down

Which quadratic function has a leading coefficient of 2 and a constant term of –3?

f(x) = 2x3 – 3
f(x) = –3x2 – 3x + 2
f(x) = –3x3 + 2
f(x) = 2x2 + 3x – 3

Answers

The answer is f(x) = 2x2 + 3x – 3

f(x) = ax² + bx + c
a - the leading coefficient
c - the constant term

We are looking for a = 2, c = -3

Through the process of elimination:
The first (f(x) = 2x3 – 3) and the third choice (f(x) = –3x3 + 2) have x³ so these are not quadratic function.

In the function: f(x) = –3x2 – 3x + 2
a = -3
c = 2

In the function: f(x) = 2x2 + 3x – 3
a = 2
c = -3

Answers

The correct answer is 6

When p equals 1/3, 9p^2 calculates to 1 after squaring p and multiplying by 9.

The question involves calculating the expression 9p^2 given that p = 1/3. First, we square the value of 'p' and then multiply it by 9. Following the process, we have:

[tex](\frac{1}{3} )^2 = \frac{1}{9} \\9 \times (\frac{1}{9} ) = 1[/tex]

Therefore, 9p^2 is equal to 1 when p is equal to 1/3.

how to integrate arctan 3x.dx ...?

Answers

to integrate by parts u need to take 2 functions, in this case, you only have arctan(3x) and therefore you second function will just be 1. this sounds confusing but think about it: arctan(3x) = 1*arctan(3x) ill take u = arctan(3x) dv = 1 -so you know du = 3/(1+9x^2) ...... derivative of tangent inverse v = x ∫ u dv = uv - ∫ v du ∫ (arctan(3x) * 1) dx = x*arctan(3x) - ∫ (x * (3/(1+9x^2))) dx = x*arctan(3x) - ∫ (3x / (1 + 9x^2)) dx take w = 1 + 9x^2 dw = w' dx dw = 18x dx dx = dw / 18x so now you have = x*arctan(3x) - ∫ (3x)/w * dw/18x the x's cancel and you end up with = x*arctan(3x) - (1/6)*∫(1/w)dw = x*arctan(3x) - (1/6) * ln|w| = x*arctan(3x) - (ln(1 + 9x^2))/6.......1 + 9x^2 is always positive your answer: x*arctan(3x) - (ln(1 + 9x^2))/6 good luck
 to integrate by parts u need to take 2 functions, in this case, you only have arctan(3x) and therefore you second function will just be 1. this sounds confusing but think about it: 
arctan(3x) = 1*arctan(3x) 
ill take 
u = arctan(3x) 
dv = 1 
-so you know 
du = 3/(1+9x^2) ...... derivative of tangent inverse 
v = x 

∫ u dv = uv - ∫ v du 
∫ (arctan(3x) * 1) dx = x*arctan(3x) - ∫ (x * (3/(1+9x^2))) dx 
= x*arctan(3x) - ∫ (3x / (1 + 9x^2)) dx 
take w = 1 + 9x^2 
dw = w' dx 
dw = 18x dx 
dx = dw / 18x 
so now you have 
= x*arctan(3x) - ∫ (3x)/w * dw/18x 
the x's cancel and you end up with 
= x*arctan(3x) - (1/6)*∫(1/w)dw 
= x*arctan(3x) - (1/6) * ln|w| 
= x*arctan(3x) - (ln(1 + 9x^2))/6.......1 + 9x^2 is always positive 

your answer: 

x*arctan(3x) - (ln(1 + 9x^2))/6

Final answer:

The pair of sets, {x | x < 0} and {x | x > 0}, has no solution because no number can be simultaneously less than zero and greater than zero. The other pairs do have solutions as they include the number zero.

Explanation:

The set of mathematical expressions provided in the question represent intervals along the number line. Understanding which intervals overlap and which intervals don't is the key to comprehending which of these options potentially has a solution. To consider when these sets will have no solution, you must find where no numbers exist that can satisfy both conditions simultaneously.

The first pair, {x | x < 0} and {x | x > 0}, means 'the set of all x such that x is less than 0' and 'the set of all x such that x is greater than 0'. Because no number can be both less than zero and greater than zero at the same time, this pair has no solution.

The other pairs, {x | x ≤ 0} and {x | x ≥ 0} and {x | x ≤ 0} or {x | x ≥ 0} do have solutions because they both include 0 itself, so there are numbers that can satisfy both conditions.

Vanessa deposited money into a bank account that earned 1.25% simple interest each year. After 1/2 year, she had earned $5.00 in interest on the account. If no other money was deposited into or withdrawn from the account, how much was her initial deposit

Answers

In order to figure this out we first have to divide the interest by 2 since it was only half a year.
