Step-by-step explanation:
The formula for any geometric sequence is an = a1 · rn - 1 , where an represents the value of the n th term, a1 represents the value of the first term, r represents the common ratio, and n represents the term number. What is the formula for the geometric sequence 4, 8, 16, 32, ...?
A. an = 4 · (1/2) n - 1
B. an = 2 · 4 n - 1
C. an = 32 · 2 n - 1
D. an = 4 · 2 n - 1
Answer: The correct answer would be
D. an = 4.2n-1
Step-by-step explanation: First, calculate the ratios between each term and the one that precedes it.
8/4=2 ....16/8=2...32/16= 2...
Upon comparing the ratios we see the ratio between each term and the one that precedes it is 2 for all the terms, the sequence is geometric, and the common ratio is r = 2.
Now, we simply need to find the other unknown values in the equation, a1= the first term of the sequence which is 4, Therefore a1=4
Looking at the options provided we see that no further missing quantity can further be found so we put this in the equation provided for a geometric sequence.
We get 4. 2n-1, which is our answer.
Jason is training to run a marathon. His goal for this week is to run a minimum of 35 miles. So far this week, he has already run 15 miles. Which inequality could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal?
A. 4m – 15 ≥ 35
B. 4m + 15 > 35
C. 4m + 15 ≥ 35
D. 4m + 15 ≤ 35
Answer:
C
Step-by-step explanation:
it says a minimum of 35 miles so that means it can be equal to 35 or more. He only ran 15 miles so he would have to run more. That’s why there would be a plus sign

Solve 1/2 + 1/3w = 1/6. Show your work.
pls help! i will give brainly
Answer:
w = -1
Step-by-step explanation:
1/2+1/3+1/6
Multiply both sides by 6
6(1/2)+6(1/3w)=1
3+2w=1
Subtract 3
2w=-2
Divide by 2
w=-1

If the perimeter is 20 what must be the length of the missing side length? (Answer with Number Only) *
Answer:
8
Step-by-step explanation:
Perimeter = Sum of all side lengths
If perimeter = 20, then 5 + 3 + 4 + x = 20
( where x = missing side length )
5 + 3 + 4 = 12
12 + x = 20
20 - 12 = 8
Hence, x = 8

Sandra saves 10% of her salary for retirement. This year her salary was $1,000 more than in the previous
year, and she saved $4,200. What was her salary in the previous year?
Answer:
$41000
Step-by-step explanation:
If her salary was $1,000 more than the previous year and she save $4,200, $4,200 was 10% of her salary. So we should create an equation. (x being her salary from the previous year)
0.1(x+1000)=4200 (divide 4200 by .01)
x+100=42000
42000-1000= 41000
