The rule for exponents is that an exponent in the numerator is the same as its opposite in the denominator, and vice versa.
The exponent of <em>-a</em> in the numerator is the same as an exponent of <em>a</em> in the denominator.
Answer: the area is 20 square centimeters.
Step-by-step explanation:
The area of an arc of angle x in a circle of radius r is:
A = (x/3.14)*3.14*r^2 = x*r^2
here we have x = (4/5)*3.14 and r = 5cm
Then the area is:
A = (4/5)*(5cm)^2 = 20cm^2
Answer:
<h2>
y= -x -10</h2>
y=mx+b
plug in -6 for y and -4 for x and - for m
-6=-(-4)+b
solve for b
b=-10
set up equation
