Answer:
b. 495
Step-by-step explanation:
Given
15, 21, 27, 33, 39, ...., 75
Number of terms = 11
Required
Evaluate
To evaluate means to add up all term of the series above;
The first step is to determine if the series is arithmetic or exponential;
If its arithmetic, then the difference between successive terms must be equal;
In other words;
21 - 15 = 27 - 21 = 33 - 27 = 39 - 33 = 6
<em>Since the result of the above expression gives 6, then it is an arithmetic series;</em>
<em></em>
The sum of n terms of an arithmetic series is calculated as this
Where n = 11
a = First term = 15
T_n = Last term = 75
The formula becomes
Hence, the series when evaluated is 495
Hello!
Okay so our starting point is - 1,260 feet
Now it is descending (-) 5 ft per minute for 12 minutes
So we multiply -5 (negative because it is descending) by 12
-5 x 12 = -60
So now we add -60 to -1,260
This would be -1,320
So the submarine's new position in relation to the sea level is -1,320
Hope this helped. Have a great day!

Answer:
124
Step-by-step explanation:
In the absence of any information about interest compounding, we'll assume that simple interest applies. The balance is ...
A = P(1 +rt) . . . . . principal P, annual rate r, for t years
A = 100(1 +0.03×8) = 100×1.24
A = 124
124 would be in the account after 8 years.
_____
<em>Additional comment</em>
If interest is compounded annually, the amount would be ...
100(1.03^8) ≈ 126.68
