Answer:
1/5
Step-by-step explanation:
5 = 1/5
6= 1/6
1/6= 6/1 (or just 6)
5/6= 6/5
Do you see the pattern?
Every number has a reciprocal except for 0. There is nothing you can multiply by 0 to create a product of 1, so it has no reciprocal.
Answer:
A
Step-by-step explanation:
Dilation by 3 from origin causes each point to be multiplied by 3.
(3,3) * 3 = (9, 9)
(6, 6) * 3 = (18, 18)
(9, 3) * 3 = (27, 9)
which is A
Answer:
Step-by-step explanation:
Initial number is 64 players
<u>Number of players reduce twice every run and will be equal to 2 to reach the grand final</u>
- 64*(1/2)^x = 2
- (1/2)^x = 1/32
- 2^-x = 2^-5
- -x = -5
- x = 5
Number of runs is 5
64 > 32 > 16 > 8 > 4 > 2
Answer:
x²=5-x
x²+x-5=0
1x²+1x²-5=0
[ax²+bx²+c=0]
∆=b²-4ac
∆=1²-4(-5)(1)=1+20=21
x=(-b±√∆)/2a
x=(-1±√21)/2
meaning:
x=(-1+√21)/2 or x=(-1-√21)/2
