Answer:
r1 is given by the formula an=a1r.n-1
Step-by-step explanation:
Well, first, we must subtract-2 by 1, as the negative sign next to 1 is inside the parentheses.
Now remember, since it is an absolute value, meaning the distance from that number to zero, we will now disregard the negative sign and get our answer: 3
Answer:
<h2>12</h2>
Step-by-step explanation:
The Mean is the average of the numbers: a calculated "central" value of a set of numbers.
To calculate it:
• add up all the numbers,
• then divide by how many numbers there are.
We have: 18, 16, x, 9, 12, 23 - six numbers (<em>n = 6</em>) and <em>mean = 15.</em>
Substitute:
Answer:
17m+57
Step-by-step explanation:
Combine like terms: 34+23 is 57 and 15+1+1 is 17 so its 17m+57
Hope this helps plz mark brainliest :D
So for this, you will be using the exponential equation formula, which is y=ab^x , with a = initial value and b = growth/decay.
Since we start out with 855, that is your a variable.
And since this is a growth by 6%, add 1 and 0.06 (6% in decimal form) together, which is 1.06. That is your b variable.
In this case, time is the independent variable. therefore 1 year is the x variable.
Using the prior info, we can form our equation to be: y = 855(1.06)^1 . From here we can solve for y.
Firstly, solve 1.06^1: y = 855(1.06)
Next, multiply everything, and your answer should be y = 906.30 . In this context, there will be $906.30 in your account after 1 year.
