Answer:
5115
Step-by-step explanation:
We know:
a_1 = 5 the first term in the geometric sequence.
r = 2
We want Sum a_i for i = 1 to 10
a_n = 5* 2^(n-1)
Sum a_i for i = 1 to 10 = G
G = a_1* (2*2^(n-1) - 1) / (2 - 1)
G = 5 * (2^(n) - 1)/ (2 - 1), n = 10
G = 5* (2^(10) - 1)
G = 5*(1024 - 1) = 5*(1023) = 5115
Answer:
-0.8
Step-by-step explanation:
1. When subtracting or adding negative numbers, remember these rules:
Same signs add and keep
Different signs subtract
Keep the sign of the higher number.
2. -0.1 and -0.7 both have the same sign (they're both negative numbers), so add them together.
-0.1 - 0.7 = -0.8
3. The answer is negative based on the rules listed above in step 1.
