Answer:

Step-by-step explanation:

If the radius of a cylinder is increased by 20% and its height is decreased by 10%.

To find : What is the percentage change in the volume?

Solution :

Let r be the radius of cylinder is increased by 20%

i.e,

The old radius is 5 and new radius is 6.

Let h be the height of cylinder is increased by 10%

i.e,

The old height is 10 and new height is 11.

The volume of old cylinder with r=5 and h=10

The volume of new cylinder with r=6 and h=11

Volume change is

Percentage change is

Therefore, The percentage change in the volume is 6.4%.

If L is the line having x -intercept of -1 and y -intercept of 3, complete the equation of L .

frozen [14]

Answer:

y = 3x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 3)

m = $\frac{3-0}{0+1}$ = 3

We are given the y- intercept, that is c = 3

y = 3x + 3 ← equation of line

Which of the following is the equation for the graph shown?

masha68 [24]

The equation of the circle shown is:

$x^2 + y^2 = 100$

<h3>What is the equation of a circle?</h3>

The equation of a circle of center $(x_0, y_0)$ and radius r is given by:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

From the graph, it can be seen that the center of the circle is (0,0), thus $(x_0, y_0) = (0,0)$ and the radius is of r = 10, hence the equation is:

$x^2 + y^2 = 100$

Answer:

d = 10/72

Step-by-step explanation:

c and d vary inversely

c = k/d

Where,

k = constant of proportionality

d = 2/9 when c = 5

c = k/d

5 = k ÷ 2/9

5 = k × 9/2

5 = 9k/2

Cross product

5*2 = 9k

10 = 9k

k = 10/9

c = k/d

c = 10/9 ÷ d

c = 10/9 × 1/d

c = 10/9d

find d when c = 8

c = 10/9d

8 = 10/9d

Cross product

8*9d = 10

72d = 10

d = 10/72

Can someone help me on this

Ierofanga [76]

1/2 of angle D is given as 32 degrees.

The 3 inside angles need to add up to 180 degrees.

Angle B is a right angle, which is 90.

Angle C = 180 - 90 - 32 = 58 degrees.
