Answer:
r = 1.7 percent
Step-by-step explanation:
I = P(1+r)^nt
assuming the principal is the same
yearly
I = (1 +.07)^1
quarterly
I = (1+ r) ^4t
lets find the quarterly interest rate if we get the same interest
(set the equations equal)
(1 +.07)^1= (1+ r) ^4
simplify
1.07 = (1+r) ^4
take the 4th root on each side
(1.07) ^ (1/4) = (1+r) ^ 4 ^ (1/4)
1.017058525 = 1+r/4
subtract 1
.017058525 = r
multiply by 100
r = 1.7 percent

Answer:
0.6 miles
Step-by-step explanation:
Given that,
A biking track has a length of 3168 feet (ft).
We need to find the distance in miles.
We know that, 1 mile = 5280 foot
1 feet = (1/5280) mile
Now, we can find the distance in miles by multiplying 3168 by (1/5280).

So, the distance covered is 0.6 miles.
Answer:
el valor creo que es 2 nooo

Lets get started :)
Referring to the picture I have uploaded might help you
We have the same base, which in this case is x.
When multiplication occurs in the same base, we add the powers

↓ (I am going to perform the problem separately and then give the final answer as the power to x)

=

↓
x²

The power of a power should be performed by multiplying the powers together.
2 x

=


Your final answer will be the second option
