a sphere has a radius of 2.5 and a volume of 65.42. a second sphere has twice the radius of the first sphere. a third sphere has a diameter that is three-fourths of the diameter of the first sphere. what is the radius of the third sphere?

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

answer: its the third option.

step-by-step explanation:

i just took the test.

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
