ANSWER!
93
EXPLANATION!
The sequence is doubling every number, so it would continue as
3,6,12,24,48
Now you are finding the sum, so addition. All you need to do now is add all those numbers.
3+6+12+24+48=93
Answer:
(c)y= -1/3x+1
Step-by-step explanation:
it is the answer
It's unclear what the planes are supposed to be, so I'll take
and
with
.
The cross sections are disks with diameter
, so each disk of thickness
has a volume of

Then taking infinitesimally thin disks, we find the solid has a volume of

Since

and


it follows that the volume is



Answer:
The zeroes are 2, -2, -6, 5.
Step-by-step explanation:
If 2 of the zeroes are 2 and -2 then (x - 2)(x + 2) is factor of the polynomial.
We can now do long division.
Note (x - 2)(x + 2) = x^2 - 4, so we have:
x^2 - 4 ( x^4 + x^3 - 34x^2 - 4x + 120 ( x^2 + x - 30 <--- Quotient
x^4 - 4x^4
x^3 - 30x^2 - 4x
x^3 -4x
-30x^2 + 120
-30x^2 + 120
x^2 + x - 30 = 0
(x + 6)(x - 5) = 0
x = -6, 5.
