Answer:
The answer is B
Step-by-step explanation:
Quadratic equations always have two answers unless the radical is a negative. You can not square root negatives.
A little confused but it would be just 10 degrees I think! Oof! Idk
Cost of each dozen of Japanese andagi = $7.29
The above sentence can also be written as
Cost of 12 Japanese andagi = $7.29
Then
The cost of each doughnut = (7.29/12) dollars
= 0.607 dollars
= 0.61 dollars
So the cost of each doughnut or Japanese andagi is $0.61.
I hope the answer is what you
were looking for and the procedure for solving this question is also clear
enough for you to understand. You can use this procedure to solve similar
problems in future.
f(t) = 3.7t + 21
where t is the time in months
f = 3.7t /t + 21 / t
f = 3.7 + 21/t
All three series converge, so the answer is D.
The common ratios for each sequence are (I) -1/9, (II) -1/10, and (III) -1/3.
Consider a geometric sequence with the first term <em>a</em> and common ratio |<em>r</em>| < 1. Then the <em>n</em>-th partial sum (the sum of the first <em>n</em> terms) of the sequence is
Multiply both sides by <em>r</em> :
Subtract the latter sum from the first, which eliminates all but the first and last terms:
Solve for 
:
Then as gets arbitrarily large, the term 
will converge to 0, leaving us with
So the given series converge to
(I) -243/(1 + 1/9) = -2187/10
(II) -1.1/(1 + 1/10) = -1
(III) 27/(1 + 1/3) = 18
