The pyramid has a greater volume.
The volume of the cone is 1436.7 ( to 5 sf )
The volume of the pyramid is 1437.3 ( to 5 sf )
Both of them is 1440 when rounded off to 3 sf. However , the volume of the pyramid is greater.
( so sorry I can’t explain well but I hope it helps )
The solution is in the picture:) hope you understand better!! Sorry if It’s confusing

Find the 7th term of the expansion of (3c + 2d)^9.
defon

Answer:

c

Step-by-step explanation:

Using Pascal's triangle, the expansion, although EXTREMELY lengthy, will help you find the 7th term.  I am going to type out the expansion only up til the 7th term (although there are actually 10 terms because we are raised to the power of 9).  If you would like to learn how to use Pascal's Triangle for binomial expansion, you will need to visit a good website that explains it because it's just too difficult to do it via this website.

The expasion is as follows (up to the 7th term):

1(3c)^{9} +9(3c)^{8}(2d)^{1} +36(3c)^{7}(2d)^{2} +84(3c)^6(2d)^3+126(3c)^5(2d)^4+126(3c)^4(2d)^5+84(3c)^3(2d)^6

That last term is the 7th term.  You find out its value by multiplying all the numbers together and adding on the c^3d^6.  Again those come from Pascal's triangle, and it's one of the coolest math things ever.  I encourage you to take the time to explore how it works.

Locating Zeros of Polynomial Function:<br>Approximate the real zeros to the nearest tenth
solmaris [256]

we are given

f(x)=2x^4-x^3+x-2

we can check each options

option-A:

-1,1

we can plug x=-1 and x=1 and check whethet f(x)=0

At x=-1:

f(-1)=2(-1)^4-(-1)^3+(-1)-2

f(-1)=0

At x=1:

f(1)=2(1)^4-(1)^3+(1)-2

f(1)=0

so, this is TRUE

option-B:

0,1

we can plug x=0 and x=1 and check whethet f(x)=0

At x=0:

f(0)=2(0)^4-(0)^3+(0)-2

f(0)=-2

At x=1:

f(1)=2(1)^4-(1)^3+(1)-2

f(1)=0

so, this is FALSE

option-C:

-2,-1

we can plug x=-2 and x=-1 and check whethet f(x)=0

At x=-2:

f(-2)=2(-2)^4-(-2)^3+(-2)-2

f(-2)=36

At x=-1:

f(-1)=2(-1)^4-(-1)^3+(-1)-2

f(-1)=0

so, this is FALSE

option-D:

-1,0

we can plug x=-1 and x=0 and check whethet f(x)=0

At x=-1:

f(-1)=2(-1)^4-(-1)^3+(-1)-2

f(-1)=0

At x=0:

f(0)=2(0)^4-(0)^3+(0)-2

f(0)=-2

so, this is FALSE

an elevator started at the first floor and went up 18 floors. it then came down 11 floors and went back up 16.at what floor was
zzz [600]
Started at first floor
went up 18 floors, so now we are at 1+18 or 19th floor
then cam down 11 floors, so now we are at 19-11 or 8th floor
then went up 16, so now at 16+8 or 24th floor

it stopped at 24th floor
