pls help asap, find the height of the cylinder and round to the nearest tenth

Answers

Answer:

h = 2.4

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h  where r is the radius and h is the height

271.4 = pi ( 6)^2 *h

271.4 = 36* pi* h

Letting 3.14 = pi

271.4 = 113.04 h

Divide each side by 113.04

271.4 /113.04 = 113.04h/113.04

2.424805379 = h

Rounding to the nearest tenth

2.4 = h

OR if we use the pi button

271.4 = 36 * pi *h

Divide each side by 36 pi

271.4/36pi = h

h=2.3997

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Researching the problem on the internet, there was a base fee of $18.99, which is the y-intercept, and there was an additional charge of 75 cents for each mile driven, which is the slope, hence the cost function for m miles driven is given by:

C(m) = 18.99 + 0.75m.

He paid $199, hence the number of miles he drove is found as follows:

C(m) = 18.99 + 0.75m.

199 = 18.99 + 0.75m

m = (199 - 18.99)/0.75

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Item a:

He has 3/5 of 40 videogames left, hence:

3/5 x 40 = 3 x 8 = 24.

He has 24 videogames left.

He kept 5/8 of the 24 videogames, hence:

5/8 x 24 = 5 x 3 = 15.

He kept 15 videogames for himself.

He also sold 9 videogames for $7,200, hence the selling price of one of them is:

7200/9 = $800.

Item c:

A bisector is the required line that divides a given line or an angle into two equal parts. The required construction of the bisectors is shown in the attachment to this answer.

Bisection is the process in which a given line or angle is divided into two equal parts by constructing the required bisector. Thus the steps to bisect the given arcs are stated below:

For figure 1:

Open the compass to any radius, using point A as the center draw arcs on the reverse side of the given arc AB.Repeat the same process using point B as the center and the same radius as that used in A.Join the intersections of the arcs on the reverse sides of arc AB by a line. Thus the required bisector.

For figure 2:

Open the compass to any radius, using point M as the center draw arcs on the reverse side of the given arc MN.Repeat the same process using point N as the center and the same radius as that used in M.Join the intersections of the arcs on the reverse sides of arc MN by a line. Thus the required bisector.

For figure 3:

Open the compass to any radius, using point A as the center draw arcs on the reverse side of the given arc AB.Repeat the same process using point B as the center and the same radius as that used in A.Join the intersections of the arcs on the reverse sides of arc AB by a line. Thus the required bisector. The point on arc AB through which the bisector intersects is the required point S. The mid point of arc AB.

For figure 4:

Open the compass to any radius, using point A as the center draw arcs on the reverse side of the given arc AB.Repeat the same process using point B as the center and the same radius as that used in A.Join the intersections of the arcs on the reverse sides of arc AB by a line. Thus the required bisector. Repeat the same procedures using points BC.

NB: The point of intersection of the bisectors in relation to arc AC is the radius of the given arc.

What are the equation of the line of best fit and the absolute value of the correlation coefficient?

Answers

The equation of the line of best fit is y = -4.75X + 88.6 and the absolute value of the correlation coefficient is 0.906

The equation of the line of best fit

The data values of the question are as follows:

(1, 88), (2, 75), (3, 71), (4, 69), (5,66), (6, 68), (7, 50)

To determine the equation of the line of best fit, we make use of a graphing calculator.

From the graphing calculator, we have the following summary:

Sum of X = 28Sum of Y = 487Mean X = 4Mean Y = 69.5714Sum of squares (SSX) = 28Sum of products (SP) = -133The value of R is: -0.906.

The line of best fit equation is

y = bx + a

Where

b = SP/SSX = -133/28 = -4.75

a = MY - bMX = 69.57 - (-4.75*4) = 88.57143

So, we have:

y = -4.75X + 88.57143

Approximate

y = -4.75X + 88.6

Hence, the equation of the line of best fit is y = -4.75X + 88.6

The absolute value of the correlation coefficient

In (a), we have:

The value of R is: -0.906.

This represents the correlation coefficient.

The absolute value is

|R| = 0.906.

Hence, the absolute value of the correlation coefficient is 0.906

100 POINTS!! Find the indicated angle or side. Give an exact answer.
Find the measure of angle A in degrees.

Answers

Answer:

A = 120

Step-by-step explanation:

To find angle A we will need to use the law of cosines, since we know the three sides of the triangle.

a^2=b^2+c^2−2*b*c*cosA

(2 sqrt(13)) ^2 = 6^2 + 2^2  + 2 * 6 * 2 cos A

4*13 = 36 + 4 - 24 cos A

52 = 40- 24 cos A

12 = -24 cos A

-1/2 = cos A

Take the inverse cos of each side

cos^-1(-1/2) = cos^-1(cos A)

120 = Cos A  or 240 = Cos A

A cannot be greater than 180 so A = 120

Answer:

A = 120°

Step-by-step explanation:

We can use the cosine rule to solve for angle A, since lengths of all sides are known:

[tex]a^2 = b^2+ c^2 - 2(b)(c) \space\ cos A[/tex]

where a, b, and c are the sides opposites angles A, B, and C respectively.

a = 2√3 , b = 6, c = 2

• Rearranging the formula to make A the subject:

[tex]2(b)(c) \space\ cos A = b^2 + c^2 -a^2[/tex]

⇒  [tex]cos A = \frac{b^2 + c^2 -a^2}{2(b)(c)}[/tex]

⇒  [tex]A = cos^{-1}(\frac{b^2 + c^2 -a^2}{2(b)(c)} )[/tex]

• Now we can substitute the values into the equation to calculate the value of angle A:

[tex]A = cos^{-1}(\frac{6^2 + 2^2 -(2\sqrt{13})^2}{2(6)(2)} )[/tex]

⇒  [tex]A = cos^{-1} (-\frac{1}{2} )[/tex]

⇒  A = 120°
