Answer:
a. T1 = -4 , T2 = -4/3 , T3 = -4/9 , T4 = -4/27
b. It is converge
c. The sum to ∞ = -6
Step-by-step explanation:
a.
∵ Tn = -4(1/3)^(n-1)
∵ The lower n = 1
∵ The geometric series Tn = a(r)^(n-1)
∴ T1 = a , T2 = ar , T3 = ar² , T4 = ar³
∴ a = -4 , r = 1/3
∴ T1 = -4
∴ T2 = -4(1/3) = -4/3
∴ T3 = -4(1/3)² = -4/9
∴ T4 = -4(1/3)³ = -4/27
b.
r = 1/3
∴ -1 < r < 1
∴ It is converge because the value of 1/3 when n is a very large
number will approach to zero
c.
∵ The sum of the geometric series = a(1-(r)^n)/1-r
∵ r^n ≅ 0 when n is a very large number
∴ The sum to ∞ = a/1 - r = -4/(1 - 1/3) = -4/(2/3) = -6
Answer:
If the diameter or radius of one circle is the same as another circle they are congruent.
1. True - T looks to be centered between A & M
2. True - opposite angle equal each other and H is the midpoint of each angle
3. True - complementary angles = 90 degrees and the two outside lines look like they represent a right angle
( 3 may be false, since they usually have a little square in the corner of a right angle and this picture doesn't, but it looks like one though)
Answer:
I think 15
Step-by-step explanation:
15+15=30, so both 3 or 4 point questions have 15 problems each, hope this helped
Answer:
94
Step-by-step explanation:
Since the circle equals to 142 degrees you have to subtract the already given umber (48) by the total amount and it'll give you the missing angle which is 94.
