- 4 + y i = x + 3 i
- 4 = x, y i = 3 i ;
x = - 4, y = 3
Answer:
( x, y ) = ( - 4 , 3 )
Answer:
we could work this out by geometric sequence
Step-by-step explanation:
G1=2, G2=4, we have a formula,Gn=G1r^n-1
G2=G1 (r)^1, 4=2r, r=2
G30=G1 (2)^29=1,073,741,824 bacterium
Answer:
£5 : £25
Step-by-step explanation:
Sum the parts of the ratio, 1 + 5 = 6 parts
Divide the quantity by 6 to find the value of one part of the ratio
£30 ÷ 6 = £5 ← value of 1 part of the ratio, thus
5 parts = 5 × £5 = £25
Thus 1 : 5 = £5 : £25
