Answer:
-5 or 5 depending on how you write the simplified form
Step-by-step explanation:
__
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
1/a^b = a^-b
__
Some folks like their simplified form to contain only positive exponents. Other folks avoid unnecessary fractions. Choose the form that satisfies your grader.
Answer:
Step-by-step explanation:
The formula of an area of a circle:
<em>r</em> - radius
We have the endpoints of a diameter of a circle.
The formula of a distance between two points:
Substitute the coordinates of the given points A(3, 4) and B(10, 4):
Therefore we have the length of the diameter: <em>d = 7</em>
We know: <em>d = 2r.</em> Therefore
Substitute to the formula of an area:
<em>There is no such answer in the answers to choose.</em>
<em>Apparently you have some error in the coordinates of the endpoints.</em>
