Answer:
The 5th term.
Step-by-step explanation:
a3 = a1 + 2d = 4
a9 = a1 + 8d = -8
Subtracting :
6d = -12
d = -2
So it's the 5th term because:
a5 = a3 + 2(-2)
= 4 - 2(2) = 0
The answer to this is 30.41 due to the zero the answer cannot be moved on so it will stay the same.
Answer:
16π
Step-by-step explanation:
Area = πr²
r - radius
r = d/2 = 8/2 =4
Area = 4²π = 16π
D: {0, 1, 2, 3}
R: {−3, −2, 2, 5}
The relation is a function.
That's the answer.
Answer:
(1,0)
Step-by-step explanation:
y>-3x +3
y≥ 2x-2
If we plot these two inequalities, we can see where the lines intersect, See attached graph.
They intersect at (1,0)
We can also do this mathematically:
y>-3x +3
<u>- (y≥ 2x-2)</u>
0
-5x + 5
5x
5
x
1
If x = 1:
y≥ 2x-2
y≥ 2(1)-2
y≥ 0
(x,y) = (1,0)
