D(1) = 1/12
d(n) = d(n - 1) • (- 6)
What is the 4th term in the sequence?

b). 4320 have a nice day

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q

she made 48 + y = a cookies.     not enough info is given to find the total.
