Answer:
C
Step-by-step explanation:
Okay so what we are going to do here is look at our terms first and see what gets us there.
So lets consider the first term or the first sum, when k=1.
So if k=1 then the expression should give us a positive 5. So lets check each one for a +5.
So lets start with (5k-5) if we let k equal one this first term would be 0. So this doesnt work already.
The rest however do work so we need to keep checking.
Lets let k=2
We know that when k=2 we need the value of the term to equal -5.
So lets look at (-5k+10) if we let k be -5 then this second term would be 0 and 0 is not equal to -5 so this is now out.
Now lets look at (15k-10) if we let k=2 then this is (30-10) = 20 and 20 doesnt equal 5 so that not gonna work.
So our answer here must be (-10k+15). If we let k=2 then thats (-20+15) = -5
Now just to be 100% sure lets check some other terms. Lets check the last term which would be -755. This term would be the the 77th term so lets let k=77.
(-10(77) + 15) = -770 + 15 = -755. So that also works.
Hence our answer is the series/answer choice c.

The inequality is 9 ( t + 5 ) < 6.
In mathematics, an inequality is a relation that makes a non-same comparison between two numbers or different mathematical expressions. It is used most often to examine numbers on the quantity line by using their length.
Inequality, In mathematics, is a declaration of an order relationship—greater than, extra than or same too, much less than, or much less than or identical to—between numbers or algebraic expressions.
The definition of inequality is a difference in length, amount, exceptional, social function, or another component. An instance of inequality is if you have ten of something and a person else has none.
Let t be the number.
We know that,
The phrase "5 more than a number t" is equal to adding the number t and 5
(t+5)
The phrase "the product of 9 and the quantity 5 more than a number t" is equal to multiplying 9 by (t+5)
9(t+5)
Less represent the symbol " < ".
Therefore,
The inequality that represents this problem is 9(t+5) < 6.

Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. Mike's account balance after 21 years is $69,131.44.
<h3>What is compound interest?</h3>
Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out so that interest is received on the principal plus previously collected interest in the next quarter.,
where A is the final amount
P is the principal amount
r is the rate of interest
n is the number of times interest is charged in a year
t is the number of years
The principal amount that Mike invested is $29,000. The rate of interest is 7.24% compounded daily, for 21 years. Therefore, the account balance after 21 years is
= $69,131.44
Hence, Mike's account balance after 21 years is $69,131.44.
