Answer:
hello :
Step-by-step explanation:
39w^5 - 13w^5 = 13w^5 (3 - 1) = 26w^5
Original is 100
1/4 off is 25 off
75 left
10% what's left is 75-7.5=67.5
this was already out of 100
100=67.5=32.5
1/4 off and then 10% off is the same as 32.5% discount
Answer:
option (c) $18,032
Step-by-step explanation:
Data provided in the question;
Amount deposited at the end of each day = $1
Interest paid = 8% compounded daily = 0.08
Daily interest rate = 
= 0.000219
Duration = 20 years = 20 × 365 days = 7300 days
Now,
the Future value is given as:
Future value = Part payment × 
here, r is the interest rate
n is the duration
thus,
Future value = $1 × 
or
Future value = $18033.56 ≈ $18,032
Hence, the correct answer is option (c) $18,032
Answer:
a = 2/3
Step-by-step explanation:
A cube root is the same as a 1/3 power. The square of that gives a 2/3 power.
a = 2/3
_____
<em>Additional comment</em>
You can see the relationship between a root index and an exponent if you consider what the root means.
Consider a cube root, for example. When you cube the root, you get the original number:
(∛x)·(∛x)·(∛x) = x
Now, let's write the root as a power of x: x^a.
(x^a)·(x^a)·(x^a) = x . . . . . where x^a = ∛x
We know this product is ...
x^(a+a+a) = x^(3a) = x^1
This tells us that ...
3a = 1 ⇒ a = 1/3
That is, ∛x = x^(1/3).
Of course an n-th root is multiplied by itself n times to get the original number, so the corresponding exponent is x^(1/n).
