Answer:
a3 + b3 = -7
Step-by-step explanation:
When the sequence is A.P
a1 =4 and a2= -2
Common difference,d = a2 - a1
= -2 - 4
d = -6
a3 = third term
a3 = a1 + 2d
= 4 + 2(-6)
= 4 - 12
= -8
a3 = -8
When the sequence is geometric
a1 =4 and a2= -2
Common ratio, r = a2/a1
= -2/4
r = -1/2
Or
r = -0.5
b3 = third term
b3 = ar²
= 4 * (-1/2)²
= 4 * 1/4
= 4/4
= 1
b3 = 1
a3 + b3 = -8 + 1
= -7
a3 + b3 = -7
7 is the radius of the circle
In one month she completed 5 paintings, so in 6 month she completed 6 * 5 = 30 paintings.
38 - 30 = 8 - that's how many paintings she's still about to complete.
If she can do 5 paintings in one month, she'll do 8 paintings in 1 3/5 months. If we assume that month has 30 days, she'll probalby need one month and 18 days to do it (because 3/5 from 30 is 18).
Answer:
8+x=14 x=6, 14-8=x x=6
Step-by-step explanation:
x is the answer and what you're solving. The two equations I wrote are the simplest.
:)
18%, because 50 - 100, meaning 1 is 2% so 9x2 is 18
