The surface area of a sphere is decreasing at the constant rate of 3π sq. cm/sec . At what rate is the volume of the sphere decr
olga nikolaevna [1]
Whooh



SA=4pir²
take derivitive
dSA/dt=8pir dr/dt

and do the volume as well
V=(4/3)pir³
dV/dt=4pir² dr/dt

we need to solve for dV/dt
to do taht we need dr/dt
so

dSA/dt=8pir dr/dt
given dSA/dt=3pi cm/sec
r=2
3pi=8pi2 dr/dt
3=16 dr/dt
3/16=dr/dt

now do the volume
dV/dt=4pir² dr/dt
r=2
dr/dt=3/16
dV/dt=4pi2² (3/16)
dV/dt=16pi(3/16)
dV/dt=3pi

nice
the volume of the sphere is decreasing at 3pi cm/sec as well

Y= 4x + 2<br> where the domain is the set of all of<br> the positive even numbers<br> less than 10.
inysia [295]

The range of the function y = 4x + 2 where the  domain is the set of all of

the positive even numbers  less than 10 is {10, 18, 26, 34}

The given equation is:

y  =  4x  +  2

The domain is the set of all of  the positive even numbers  less than 10.

That is, x = {2, 4, 6 ,8}

To get the range, find the values of y for x = 2, 4, 6, and 8

For x = 2:

y = 4(2)  +  2

y  =  8  +  2

y   =  10

For x = 4:

y = 4(4)  +  2

y  =  16  +  2

y   =  18

For x = 6:

y = 4(6)  +  2

y  =  24  +  2

y   =  26

For x = 8:

y = 4(8)  +  2

y  =  32  +  2

y   =  34

Therefore, the range = {10, 18, 26, 34}
