Nth term of gp = a(1 - r^n)/(1 - r), where n∞ = 10, n = ∞, a = 2, r < 1
10 = 2(1 - r^∞)/(1 - r)
10 = 2/(1 - r)
1 - r = 2/10 = 1/5
r = 1 - 1/5 = 4/5
An infinite deometric series with a beginning value of 2 that converges to 10 has common ratio of 4/5.
The first four terms are: 2, 1.6, 1.28, 1.024
Answer:
area = 15 in²
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A =
bh ( b is the base and h the height )
here b = 10 and h = 3, hence
A =
×10 × 3 = 15 in²
The answer is D. He divided both sides by 5 instead of dividing both sides by -5.
Answer: 9,364cm
Step-by-step explanation: 1 meter = 100 centimeters so it’s 93.64(100) = 9,364
