Answer 2

Answer:

C = 12.

Step-by-step explanation:

Given :-

Radius of circle , r = 2.Value of pi, π = 3

To find :-

Circumference of circle

Formula for finding circumference of circle;

Circumference of circle = 2 × π × radius.

Solution :-

Circumference of circle = 2 × π × radius.

Substitute the value of radius into the formula.

Circumference of circle = 2 × π × 2

Multiply ; 2 × 2

Circumference of circle = 4 π.

plug 3 as π.

Circumference of circle = 4 × 3

Multiply to get

Circumference of circle = 12

A cylinder has a volume of 187 cubic inches. If the radius is 3 inches, what is the height of the cylinder in inches?

Someone please help

Answers

Answer:

Step-by-step explanation:

V = pi r^2 h

V = 187

pi = 3.14

r = 3

h = ?

187 = 3.14 * 3^2 * h

187 = 3.14 * 9 * h

187 = 28.26 * h

187 / 28.26 = h

h = 6.62

Answer:

The height of cylinder is 6.61 inches.

Step-by-step explanation:

Given that :- Volume of cylinder = 187 inches ³.Radius of cylinder, r = 3 inches

We need to Find :-Height of cylinder , h

Formula Used :-

Volume of cylinder = π × r ² × h

Where,

r is the radius of cylinder. h is the height of cylinder.

Solution :-

Using Formula

Volume of cylinder = π × r ² × h

Substitute the values

187 inches ³ = π × ( 3 inches ) ² × h

Using π = 3.14

187 inches ³ = 3.14 × 9 inches ² × h

multiply

187 inches ³ = 28.26 inches ² × h

Divide , we get

187 inches ³ / 28.26 = h

6.61 inches = h

Therefore, The height of cylinder is 6.61 inches.

what is the result of a dilation of scale factor 3 centered at the origin of the line 2y + 3x=10

Answers

Answer:

(10, 15)

Step-by-step explanation:

To get the origin of the equation 2y+3x = 10, we need to get the x and y-intercept of the line.

x-intercept occurs at y = 0

If y = 0

2(0)+3x =10

3x =10

x = 10/3

x = 1.33

y-intercept occurs at x = 0

If x = 0

2y+3(0) =10

2y =10

y = 10/2

y = 5

Hence the coordinate at the origin is (10/3, 5). If this coordinate is dilated by 3, the required coordinate will be at (10/3*3, 5*3) = (10, 15)

Hence the required coordinate is (10, 15)

What is area of a rectangle ?

The area of a rectangle of length =l and breadth =b is length times its breadth . General formula of calculating area of rectangle is  length * breadth

In first case we are dividing the figure horizontally

in which there occur an upper small rectangle of l = 12cm and breadth = 9 cm and a big rectangle of L 20cm and B= 9cm

area of 1st rectangle= l*b = 12 * 9 = 108 cm^2

area of 2nd rectangle = L*B = 20 * 9 = 180 cm ^ 2

area of complete figure in 1st way  = area of 1st rectangle + area of 2nd rectangle

                                       = 108 + 180 = 288 cm^2

In second case we are dividing the figure vertically

in which there occur an  small rectangle of l = 8cm and breadth = 9 cm and a big rectangle of L =18cm and B= 12cm

area of 1st rectangle= l*b = 8 * 9 = 72 cm^2

area of 2nd rectangle = L*B = 18 * 12= 216 cm ^ 2

area of complete figure in 2nd way = area of 1st rectangle + area of 2nd rectangle

                                       = 72 + 216 = 288cm^2

Answers

Answer:

  C)  83°

Step-by-step explanation:

The angle marked 97° and b form a linear pair, so are supplementary.

  b = 180° -97° = 83°

Answer:

C .) 83 °

Step-by-step explanation:

Angle b and 99° are on straight line so it's supplementary angles and we know that sum of all angles of supplementary angles is 180 °.

➛ b + 97 ° = 180 °.

subtract each side by 97 °

➛ b + 97° - 97° = 180° - 97°

➛ b = 83°

The position of an atom moving inside a cathode ray tube is given by the function f(t) = t^3− 4t^2 + 3t where t is in seconds and f(t) is in meters. Find the instantaneous velocity of the atom at t = 2.5 seconds. A. 1.75 m/sec. B. 2.48 m/sec. C. 3.27 m/sec. D. 4.12 m/sec.

Answers

Answer:

A

Step-by-step explanation:

The position of an atom moving inside a cathode ray tube is given by the function:

[tex]f(t)=t^3-4t^2+3t[/tex]

Where f(t) is in meters and t is in seconds.

And we want to determine its instantaneous velocity at t = 2.5 seconds.

The velocity function is the derivative of the position function. Thus, find the derivative of the function:

[tex]f'(t)=3t^2-8t+3[/tex]

Then the instantaneous velocity at t = 2.5 will be:

[tex]f'(2.5)=3(2.5)^2-8(2.5)+3=1.75\text{ m/sec}[/tex]

Our answer is A.

Answer:

Instantaneous Velocity:

[tex]\longrightarrow\:\rm v = \dfrac{dt}{dy}[/tex]

[tex]\longrightarrow\:\rm v = \dfrac{d}{dy}( {t}^{3} - 4 {t}^{2} + 3t) \\ [/tex]

the graph that he needs to do is a straight line from the origin that passes through (3, 0.75), the correct option is the last one.

How can he use the graph to find an equivalent ratio?

He knows the relation:

3 cups of granola ⇒ 0.75 cups of raisins.

Assuming this is a proportional relation of the form:

y = k*x

Where k is a constant.

Then when x = 0, we also have y = 0, so the line also passes through the point (0, 0), which is the origin.

Then the graph that he needs to do is a straight line from the origin that passes through (3, 0.75), the correct option is the last one.

SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question. 1) Write the equation of the line x 3y

Answers

Answer:

[tex]y = -3x + 14[/tex]

Step-by-step explanation:

Required

The equation of line

perpendicular to : [tex]x -3y =9[/tex]

Passes through [tex](3,5)[/tex]

We have:

[tex]x -3y =9[/tex]

Make y the subject

[tex]3y =x - 9[/tex]

Solve for y

[tex]y = \frac{x}{3} - 3[/tex]

Compare the above equation to [tex]y = mx + c[/tex]

[tex]m =\frac{1}{3}[/tex] ---- This represents the slope

Since the line is perpendicular to [tex]x -3y =9[/tex], then its slope is:

[tex]m_2 = -\frac{1}{m}[/tex]

[tex]m_2 = -\frac{1}{1/3}[/tex]

[tex]m_2 =-3[/tex]

The equation of the perpendicular line is:

[tex]y =m_2(x - x_1) + y_1[/tex]

Where:

[tex]m_2 =-3[/tex]

[tex](x_1,y_1) =[/tex] [tex](3,5)[/tex]

So:

[tex]y = -3(x - 3) + 5[/tex]

[tex]y = -3x + 9 + 5[/tex]

[tex]y = -3x + 14[/tex]
