Find the surface area of a right cone that has a radius of 9 inches and a height of 12 inches. Round your answer to the nearest hundredth. The surface area is about ⬜ square inches.

Answers

Answer 1
Answer:

The surface area of the right cone is:

[tex]678.58in^2[/tex]

Explanation:

The surface area of a right cone is:

[tex]A=\pi r(r+\sqrt[]{r^2+h^2})[/tex]

Here, r = 9 in, and h = 12 in

so

[tex]\begin{gathered} A=9\pi(9+\sqrt[]{9^2+12^2}) \\ \\ =9\pi(9+15) \\ =216\pi \\ =678.58in^2 \end{gathered}[/tex]

Justify which statistics methodology needs to be used in the above context and
a) Determine the probability of losing money.
b) Find the probability of losing money when the standard deviation is equal to 10%.

Answers

a) The probability of losing money when standard deviation is 5% is 2.27%

b) The probability of losing money when standard deviation is 10% is 15.87%

Given,

There is an investment whose return is normally distributed.

The mean of the distribution = 10%

The standard deviation of the distribution = 5%

a) We have to determine the probability of losing money:

Lets take,

x = -0.005%

Now,

P(z ≤ (-10.005 / 5) ) = P(z ≤ - 2.001) = 0.02275

Now,

0.02275 × 100 = 2.27

That is,

The probability of losing money is 2.27%

b) We have to find the probability of losing money when the standard deviation is 10%

Let x be 0.01%

Now,

P(z ≤ (-10.01/10)) = P(z ≤ -1.001) = 0.15866

Now,

0.15866 × 100 = 15.87

That is,

The probability of losing money is 15.87%

Based on the conversion rates between kilometers and feet, the number of feet per minute for each kilometer per hour is 54.6807 feet per minute.

In other words, 1 km / h is equal to 54.6807 feet per minute.

If there are 880 ft / minute therefore, the number of kilometers per hour is:

Answers

We need to know how to calculate compound interest to solve this problem. The present value is $2577.32

Compound interest is the interest that is earned on interest. Inorder to calculate the compound interest we need to know the principal amount, the rate of interest, the time period and how many times the interest is applied in per time period. In this question we know the amount after 9 years and the rate of interest is 9.5% and the interest is compounded quarterly. We will use the formula for compound interest get the principal value.

A=P[tex](1+\frac{r}{n}) ^{nt}[/tex]

where A= amount, P= principal, t=time period, n= number of times interest applied per time period, r=rate of interest

A=$6000

r=9.5%

t=9 yrs

n=4

6000=P[tex](1+\frac{9.5}{400} )^{36}[/tex]

6000= P x 2.328

P=6000/2.328=2577.32

Kaitlin races her bicycle for 98 m. A wheel of her bicycle turns 49 times as the bicycle travels this distance. What is the diameter of the wheel? Use the value 3.14 for n. Round your answer to the nearest tenth

Answers

Answer:

0.6m

Explanation:

Given the following

Total distance covered = 98m

pi = 3.14

Circumference of the wheel is the distance travelled in one rotation. Hence;

distance travelled in one rotation = \pi d

d is the diamter of the wheel

distance travelled in 49 rotation = 49*\pi d

Since distance travelled in 49 rotation = 98m, then;

98 = 49*\pi d

Divide both sides by 49

98/49 = \pi d

2 = 3.14d

d = 2/3.14

d = 0.6m

Hence the diameter of the wheel is 0.6m

h(x) = x2 + 1 k(x) = x-2 (h - k)(3) = DONE

Answers

We are given two functions:

h(x) = x^2 + 1

and k(x) = x - 2

We are asked to find the value of:

(h - k) (3) (the value of the difference of the two functions at the point x = 3

So we performe the difference of the two functions:

(h - k) (x) = x^2 + 1 - (x - 2) = x^2 + 1 - x + 2 = x^2 - x + 3

So, this expression evaluated at 3 gives:

(h-k)(3) = 3^2 - 3 + 3 = 9

One could also evaluate what was asked by evaluating each function independently and subtracting the results of such evaluation:

h(3) = 3^2 + 1 = 10

k(3) = 3 - 2 = 1

Then, the difference is : h(3) - k(3) = 10 - 1 = 9

So use whatever method feels more comfortable for you.

The coordinates of the vertices of triangle are given as H(2,2), (J(2, 4), K(0,2)

We would determine the longest side by applying the formula for finding the distance between two points which is expressed as

[tex]\begin{gathered} \text{Distance = }\sqrt[]{x2-x1)^2+(y2-y1)^2} \\ \text{For HJ, x1 = 2, y1 = 2, x2 = 2, y2 = 4} \\ \text{Distance = }\sqrt[]{(2-2)^2+(4-2)^2}\text{ = }\sqrt[]{2^2}\text{ = 2} \\ \text{For JK, x1 = 2, y1 = 4, x2 = 0, y2 = 2} \\ \text{Distance = }\sqrt[]{(0-2)^2+(2-4)^2}=\sqrt[]{(4+4)}=\text{ }2.83 \\ \text{For HK, x1 = 2, y1 = 2, x2 = 0, y2 = 2} \\ \text{Distance = }\sqrt[]{0-2)^2+(2-2)^2}=\text{ }\sqrt[]{4}\text{ = 2} \end{gathered}[/tex]

Thus, the longest side is JK. The formula for finding midpoint is

Midpoint = (x1 + x2)/2, (y1 + y2)/2

Midpoint = (2 + 0)/2, (4 + 2)/2

Midpoint = 2/2, 6/2

Midpoint = 1, 3

an airplane flew for one hour and landed 100 miles north and 80 miles east from its origin. what was the distance traveled, speed and angle of direction from its origin?

Answers

The distance traveled by airplane is 180 miles.

The speed of the airplane is 3 miles per minute and the angle of direction from the origin is 51.34°

The airplane landed 100 miles north and 80 miles east from its origin and it flew for one hour.

Then, the total distance traveled by airplane will be:

= 100 miles + 80 miles = 180 miles.

The speed can be defined as the distance traveled by the total time taken.

Speed = distance/time

Speed = 180 miles/ 1 hour

Speed = 180 miles/60 minutes

Speed = 3 miles per minute

The angle of direction from its origin will be:

tan (x) = 100 miles/80 miles

x = tan⁻¹ ( 100/80)

x = tan⁻¹ ( 10/8) =  tan⁻¹ ( 5/4)

x = 51.34°

13. Puppies have 28 teeth and most adult dogs have 42 teeth. Find the primefactorization of each number. Write the result using exponents. (Example 5)

Answers

To solve our question, first we need to know that a prime factorization is a way to represent a number by a sequence of prime numbers that multiplied together gives us the original number.

So let's calculate our first prime factorization:

As we can see, we divide our number by the smallest prime number and then the factor we follow the same rule until we get "1" (for all divisions we just have integers).

Now, for the second number we have:

And both prime factorizations are our final answers.
