I just got on an elevator in a builing with fourteen floors. There we seven of us on the elevator, and when everyone had finished making their floor selections, everyone had selected a different even numbered floor. All even numbers from 1-14 were selected, and since there we only 7 of us, every individual chose a different number. This stuck me as a rare occurance, so I'm wondering - what are the odds of this happening?

I need it in the form a + bi

I mistyped this earlier...... the i's are i as in -1, not the letter i

a) (2-3i)^2
b) (2i+3)(3i^3 - 4i^2 + 7)
c) (2+3i)/(1-2i) rationalize

I'm not just looking for the answers. I'm hoping someone can provide those, but also the work used to get them, so I can visualize what you did.

Thank you so much! I appreciate your time.

Please assist.

The function gives the cost of a certin item is defined as

C(x)=

5x if o 4x if 10< or equal to X<30
3.5x if 30< or equal to X<60
3.25x if X> or equal to 60

Where X is the number of pounds of a certin commodity sold and c(x) is measured in dollars. Determin the value of X foe wchich the function C is discontinous?

Let G1,G2,G3,.....Gp denote the respective sums to infinity of p geometric progressions,with first terms 1,2,3,...p and common ratios 1/2,1/3,.........1/(p+1) respectively...whats the value of G1+G2+G3+...Gp ?


Question:

"..Let G1,G2,G3,.....Gp denote the respective sums to infinity of p geometric progressions..."


does this statements means below ?

so, G1=1
G2=1+2
G3=1+2+3

Gp=1+2+3.....+p




Question:

"...and common ratios 1/2,1/3,.........1/(p+1)..."

what does it mean ? common ratios of what ? common ratio's of G1,G2,G3 or what ?...

please explain

A 0.400 kg toy truck moving at an initial speed of 0.100 m/s collides head-on with a 0.300 kg toy car at rest. The collision is elastic. Find their final speeds and directions.
a. v1 = 0.100 m/s v2 = 0.0 m/s
b. v1 = 0.0 m/s v2 = 0.100 m/s
c. v1 = 143 m/s v2 = 114 m/s
d. v1 = 0.0143 m/s v2 = 0.114 m/s

1).a^(n)-b^(n)can be expressed as
difference of at least one set of two squares
like 7 ^ (3) - 4 ^ (3) = 48 ^ (2) - 45 ^ (2)
2).any number say c having any power n can be
expressed as difference of at least one set of
two squares like
7 ^ (3) = 172 ^ (2) - 171 ^ (2)
from this prove that
a ^ (n) - b ^ (n) = c ^ (n)
is not possible.
hint :- (any number) ^ (n) cannot be 0 for any value of n.

if a ^ (n) - b ^ (n) =c ^ (2) - d ^ (2) like
7 ^ (3) - 4 ^ (3) = 48 ^ (2) - 45 ^ (2) &
a ^ (n) or b ^ (n) can be expressed
as difference of two at least one set of two squares also like
7 ^ (3) =172 ^ (2) - 171 ^( 2) or any number
say x having any power n can also be expressed
as difference of at least one set of two squares i.e
x ^ (n) = h ^ (2) - j ^ (2)
prove that a ^ (n) - b ^ (n) = x ^ (n)
is not possible.a,b,x are natural or rational numbers and n is
a natural power.
hint :- (any number) ^ (0) is undefined.
