Variable y varies directly with variable x, and y = 18 when x = 4. What is the constant of variation in decimal form?

1 answer:

5 0

To find the constant of variation, you must use the following equation:

y = kx

'k' is the constant of variation.

y = 18
x = 4
k = ?

18 = k(4)
18/4 = k
k = 4.5

Answer: The constant of variation is 4.5

A cylinder with a height of 12 cm is inscribed in a sphere with a radius of 10 cm. Find the lateral area of the cylinder. Answer

zalisa [80]

Answer:

256π

Step-by-step explanation:

Given that:

The height of the cylinder: 12 cm

The radius of the sphere : 10

Let r is the radius of the cylinder, use Pytagon

10² = r² + 6²

<=> r² = 10² - 6² = 64

<=> r = 8

Hence, the lateral area of the cylinder

L= 2πrh

= 2π8*16

= 256π

It's almost easier for you to do this than it is to post a question on Brainly.

All you need to do is type the relevant expressions. Once you have Desmos show you the vertex, writing the x= equation for that is all that is required to draw it.
