Answer:

y+1 = -1(x+10)

Step-by-step explanation:

The point slope equation of a line is

y-y1 = m(x-x1) where m is the slope  and (x1, y1) is a point on the line

y - -1 = -1 (x --10)

y+1 = -1(x+10)

Answer:

The volume of the cone is 108π(pi). if the height is 9

Step-by-step explanation:

V = πr2h / 3     (formula for finding the volume)

V = π62(9) / 3

V = 324π / 3

V = 108π

You can change the value of height if its different for you

Step-by-step explanation:

Total number of cards = 48

Red cards/black cards = 1/1

(so, 24 each of read and black cards)

8 red cards are removed.

Now, there will be (24-8) number of cards left in the pack which equals to 16 cards.

So, now the number of red cards in the pack= 16

Number of black cards = 24

Ratio of red card/ black card

\( = \frac{16}{24} \)

\( = \frac{2}{3} \)

Hope this helps...

Answer:

y=3x−4

Step-by-step explanation:

find the tangent line to f(x)=x2−3x+5 at x=3

First, find the value of the function at the given point: y0=f(3)=5

Second, find the slope of the tangent line, which is the derivative of the function, evaluated at the point:  m=f′(3)

Find the derivative:  f′(x)=2x−3

Next, we evaluate the derivative at the given point to find the slope.

m=f′(3)=3

Finally, the equation of the tangent line is  y−y0=m(x−x0)

Plug the values that we found, we get that  y−(5)=3(x−(3))

So basically: y=3x−4

The height of the cylinders are (r - 0.5)/5 and -5.5 + (r - 0.5)/5  respectively; where r represents the radius of cylinder B

The given parameters are:

Cylinder A

Radius = 6

Height = h - 5.5

Cylinder B

Radius = r

Height = h

The surface area of a cylinder is

S = 2πr(r + h)

So, we have:

Cylinder A

Radius = 6

Height = h - 5.5

S = 2π * 6(6 + h - 5.5)

Cylinder B

Radius = r

Height = h

S = 2πr(r + h)

Substitute S = 2πr(r + h) in S = 2π * 6(6 + h - 5.5)

2πr(r + h) = 2π * 6(6 + h - 5.5)

Divide both sides by 2π

(r + h) = 6(6 + h - 5.5)

This gives

(r + h) = 6(h + 0.5)

Expand

r + h = 6h + 0.5

Evaluate

r = 5h + 0.5

Rewrite as

h = (r - 0.5)/5

So, we have

h -5.5 = -5.5 + (r - 0.5)/5

Hence, the height of the cylinders are (r - 0.5)/5 and -5.5 + (r - 0.5)/5  respectively; where r represents the radius of cylinder B

Answer:The dimensions of the scale drawing of the flag are 10 cm by 16 cm.

Step-by-step explanation:

The dimensions of a scale drawing of the flag are 10 centimeters and 16 centimeters.

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Given:

The scale factor is 1/6.

A rectangular flag is 60 centimeters by 96 centimeters.

To find the dimension of new flag:

60 x 1/6 = 10 centimeters

96 x 1`/6 = 16 centimeters.

The dimensions of a scale drawing of the flag are 10 centimeters and 16 centimeters.

Therefore, flag's dimension are 10 centimeters and 16 centimeters.

The area of the circular shaded region is given as follows:

A = 50.24 square yards.

The area of a circle of radius r is given by the multiplication of π and the radius squared, as follows:

A = πr²

The radius of a circle represents the distance between the center of the circle and a point on the circumference of the circle, while the diameter of the circle is the distance between two points on the circumference of the circle, on a segment that passes through the center. Hence, the diameter’s length is twice the radius length.

The circumference of a circle of radius r is given as follows:

C = 2πr.

Hence the radius of the inner circle is given as follows:

6.28r = 18.84

r = 18.84/6.28

r = 3 yd.

The radius of the outer circle is of 3 + 2 = 5 yd, hence the area of the shaded region is given as follows:

A = 3.14 x (5² - 3²)

A = 50.24 square yards.

Answer:

Step-by-step explanation:

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Answer:

y = 21

x + 27 + 3y + 8x + 18 = 180

Answer: It's congruent because translations, rotations, and reflections only move the shape's location and do not change the shape itself. A rotation changes the shape's position by rotating it around a specific point, but that shape is still the same. Reflections only mirror the shape, so while it will look inverted, it is still the same shape. Translations Only move a shape up or down along the y-axis or laft and right along the x-axis. Congruence essentially means that the shape has the same form and dimensions, not the exact location.
