We are told that the first term is 2. The next term is 7(2) = 14; the third term is 7(14) = 98. And so on. So, the first term and the common ratio (7) are known.
The nth term of this geometric series is a_n = 2(7)^(n-1).
Check: What is the first term? We expect it is 2. 2(7)^(1-1) = 2(1) = 2. Correct.
What is the third term? We expect it is 98. 2(7)^(3-1) = 2(7)^2 = 98. Right.<span />
Answer:
9
Step-by-step explanation:
The range of a data set is the largest number minus the smallest number. so it would be 9-0= 9
hope this helps!!
btw if somebody could please answer my recent question i would really appreciate it!!
<h2>Hello!</h2>
The answer is: 1.187 tablets each time (twice a day)
<h2>Why?</h2>
From the statement we know that 0.25 tablet (1/4) should be taken twice a day per 20 kg, it makes 0.5 table a day, per 20 kg.
First, we need to convert the given weight unit (pounds) to kg:
So,
A weight of 95 Kg, means 4.75 times more than the given information of 0.5 table a day, per 20 Kg
Then,
So,
For a weight of 95 Kg, 2.375 tablets should be taken a day, or 1.187 tablets each time.
Have a nice day!
In -2^2 since the negative sign is not in parentheses you would solve it as 2×2=4 and then have the negative sign so it would be -4. With the parentheses you are saying that the term you are squaring is (-2) and two negatives make a positive so it would be (-2)×(-2)= 4.
