You'll get -6.25
To find a negative power, put it 1 over it and remove the negative symbol. For example, to simplify 2^-4, we would do 1/2^-4, then remove the negative to get 1/2^4, which is 0.0625
Then you have that -3^3 is -27 (since -3*-3*-3 is -27). Then using the above method, you can simplify 5^-2 to 1/5^2, which is 0.4
0.0625*-27*0.4 is -27/400

Answer:
(4, 3)
Step-by-step explanation:
just is
[character limit thing]
To understand the function better, let's convert it from polar coordinates to cartesian coordinates. The relation between those coordinates are

Our function is

If we multiply both sides by r, we have

The square of the radius is equal to the sum of the squares of the cartesian coordinates

Using this identity, we can rewrite our function as

Completing the square, we can rewrite our function as

This is a equation of a circle.
Answer:
78 miles
Step-by-step explanation:
Given that:
Original length, L = 47 miles
Additional length (miles) added per day, = 1 mile
Representing as an equation :
L(D) = original length + additional length per day * number of days
Let, D = number of days
L(D) = 47 + D
Length after 31 days :
L(31) = 47 + 31
= 78 miles
