The volume of a conic wrap would be 209.44 cubic inches.

What is the volume of the cone?

The volume of a cone defines the cone's space or capacity. Cones are three-dimensional geometric shapes with a circular base that tapers from a flat base to a point known as the apex or vertex. A cone is made up of a series of line segments, half-lines, or lines that connect a common point, the apex, to all the points on a base in a plane that does not contain the apex.

      Volume of the cone = 1/3 ×πr²h

Given data:

Height of the conic wrap(h) = 8 inches.

Diameter of the conic wrap = 10 inches.

So radius(r) = 10/2 = 5 inches.

Now by using the formula for finding out the volume of the conic wrap, we get

            V = 1/3 × πr²h

               = 1/3 × 3.14 × (5)² × 8

            V = 209.44 cubic inches.

Hence, the volume of a conic wrap would be 209.44 cubic inches.

What are Equations of Motion?

The three equations of motions are :

Velocity-Time relation

v = u + at

Position-Time relation

S = ut + ( 1/2 ) at²

Position-Velocity relation.

v² - u² = 2aS

where v = final velocity

u = initial velocity

t = time

S = displacement

a = acceleration

Given data ,

Initial velocity u = 19.62 m/s

t = 2.01 s

a = -9.8 m/s² ( acceleration due to gravity )

To find maximum height of the baseball S , first we calculate the final velocity v

When the ball reaches the maximum height , the final velocity v will be 0

So v = 0

And , from the third equation of motion , we can find the maximum height of the baseball as

Position-Velocity relation.

v² - u² = 2aS

Substituting the value of v , u and a in the above equation , we get

0 - ( 19.62 )² = 2 x ( -9.8 ) x S

- 384.9444 = -19.6 x S

Dividing by ( -19.6 ) on both sides , we get

S = 19.64 m

Hence , the maximum height of the baseball will be 19.64 m

The area of the shaded region between the curves f(x) and g(x), using integrals, is of:

126.54 units².

The curves are classified as follows:

Then, between an interval [a,b], the area is given by the definite integral between a and b of the subtraction of these two curves, as follows:

[tex]A = \int_{a}^{b} f(x) - g(x) dx[/tex]

The shaded region is divided into two intervals, as the upper and the lower curve change, as follows:

The area on the first interval is of:

[tex]A_1 = \int_{-4}^{0} x^3 + x^2 - 20x dx[/tex]

[tex]A_1 = 0.25x^4 + 0.33x^3 - 10x^2|_{x = -4}^{x = 0}[/tex]

Applying the Fundamental Theorem of Calculus, the first area is of:

A1 = -0.25(-4)^4 - 0.33(-4)³ + 10(-4)² = 117.12 units squared.

The second area is of:

[tex]A_2 = \int_{0}^{1} -x^3 - x^2 + 20x dx[/tex]

[tex]A_2 = -0.25x^4 - 0.33x^3 + 10x^2|_{x = 0}^{x = 1}[/tex]

Hence:

A2 = -0.25 - 0.33 + 10 = 9.42 units squared.

Answer:

  (6)  The functions f and g are not inverses

Step-by-step explanation:

You want to know which of several statements proves f(x) = (9x+9)/7 and g(x)=(7x+9)/9 are inverses of each other.

The inverse of f(x) can be found by solving ...

  x = f(y)

  x = (9y +9)/7

  7x = 9y +9

  7x -9 = 9y

  y = (7x -9)/9

The plus sign in f(x) turns into a minus sign in its inverse function. g(x) is not the inverse of f(x).

The functions f and g are not inverses.

__

Additional comment

As answer choice (2) suggests, graphs of inverse functions will be reflections of each other in the line y=x. The attached graph shows they are not, hence f(x) is not the inverse of g(x).

The correct statement that correctly verifies the two functions f(x) = (9x + 9) / 7 and g(x) = (7x + 9) / 9 is the functions f and g are not inverses

The inverse of a function is solved by making the input function equal to the output function

the inverse of f(x) = (9x + 9) / 7

f(x) = y = (9x + 9) / 7

7y = 9x + 9

9x = 7y - 9

x = (7y - 9) / 9

changing the input and output of the new functions

hence f⁻¹ =  (7x - 9) / 9

Since f⁻¹ ≠ g(x) the last option is the correct option

Answer:

Step-by-step explanation:

The actual number of respondents who rated themselves as above average drivers is 852 and we can conclude that the proportion respondents who rated themselves as above average drivers is greater than 0.5007.

Given that, 84% of the sample of 1014 adults rated themselves as above average drivers.

In statistics, a simple random sample is a subset of individuals chosen from a larger set in which a subset of individuals are chosen randomly, all with the same probability. It is a process of selecting a sample in a random way.

Now,

84% of 1014

= 0.84×1014

= 851.76

≈ 852

Thus, the actual number of respondents who rated themselves as above average drivers is 852.

At the null hypothesis, we test if the proportion is 4/5 =0.8, that is

[tex]H_0:p=0.8[/tex]

At the alternative hypothesis, we test if the proportion is greater than 80%, that is:

[tex]H_0:p\ge0.8[/tex]

The test statistic is given by

[tex]z=\frac{\bar{p}-p}{\sqrt{\frac{p(1-p)}{n} } }[/tex]

In which:

[tex]$\bar{p}$[/tex] is the sample proportion.

p is the proportion tested.

n is the size of the sample.

In this problem, the parameters are [tex]$\bar{p}$[/tex]=0.84, p=0.8 and n=1014

Thus, the value of the test statistic is

[tex]z=\frac{0.84-0.8}{\sqrt{\frac{0.8(1-0.8)}{1014} } }[/tex]

= 0.04/0.0125

z=3.2

0.4993

So, 1-0.4993=0.5007

Therefore, the actual number of respondents who rated themselves as above average drivers is 852 and we can conclude that the proportion respondents who rated themselves as above average drivers is greater than 0.5007.

The annual interest rate needed to accumulate $ 21.02 in simple interest from a $400.00 principal over 0.416667 years (5 months) is 12.612%.

The amount that the lender charges the borrower above and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.

Here,

Simple interest paid=421.02-400

=$21.02

For ease of calculation, convert 5 months to 12 months per year, which equals 0.416667 years.

In order to convert r's decimal value to a percentage, we must solve our equation:

r = 21.02 / (40080.416667) = 0.1261199

What is a selective principle in mathematics?

A selection principle is a rule in mathematics that asserts the possibility of obtaining mathematically significant objects by selecting elements from given sequences of sets. Selection principle theory investigates these principles and their relationships to other mathematical properties.

The price of each short is $20.98.

The price of each T-shirt is $12.49.

The price of each cap is $7.59.

The price of each pair of shoes is $16.50.

Konrad can buy only 3 items so he can buy 2 shorts and one T-shirt

So the total amount spent by Konrad = 2*20.98 + 12.49

                                                              = 41.96 + 12.49

                                                              = 54.45 dollars

which is less than $55.

Marek can buy only 5 items so he can buy 3 T-shirts and 2 caps.

So the total amount spent by Marek = 3*12.49 + 2*7.59

                                                              = 37.47 + 15.18

                                                              = 52.65 dollars.

which is less than $55.

Ming can buy only 4 items so he can buy 2 T-shirts and one cap and one short.

So the total amount spent by Ming = 2*12.49 + 7.59 + 20.98            

                                                          = 53.55 dollars.

which is less than $55.

Hence,

Konrad will buy 2 shorts and one T-shirt.

Marek will buy 3 T-shirts and 2 caps.

Ming will buy 2 T-shirts and one cap and one short.

According to the give triangle ABC, the length of the line segments

BD is 5.5

CD is 13.5

AC is 10.5

Triangle:

Triangle refers a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees.

Given,

AD is a median in ΔABC, if BD = 5x - 8, CD = 3x + 12, and AC = 7x -14.

Here we need to find the length of the all three segments.​

We know that, the length of BC is the sum of BD and CD.

Thus can be written as,

BC = BD + CD

Now, we have to apply the values on the equation, then we get,

Length of BC is x.

=> 5x - 8 + 3x + 12

=> 8x - 4

=> 8x = 4

=> x = 1/2

Now, we have to apply the value of x as 1/2, on the line segments, then we get,

BC = 5(1/2) - 8

BC = 5/2 - 8

BC = 11/2 = 5.5

So, the value of CD is,

CD = 3(1/2) + 12

CD = 3/2 + 12

CD = 27/2

CD = 13.5

Then the value of AC is,

AC = 7(1/2) - 14

AC = 7/2 - 14

AC = 21/2

AC = 10.5

Therefore, the line segments BC is 5.5, CD is 13.5 and AC is 10.5.
