Answer:
16.9 m
Step-by-step explanation:
Start with a half a circle. The central angle of a semicircle is 180 deg.
Now subtract 21 deg on each side.
180 - 21 - 21 = 138
The central angle is 138 deg.
The radius is 7 m.
Now we use the formula for the length of an arc of a circle given the radius of the circle and the central angle of the arc.
Answer:
You could by 8 magazines
Step-by-step explanation:
First, set up the equation 6/12=x/16
cross multiple to get 12x=96
divide both sides by 12 and x = 8
Change 4 feet to inches
4 feet is 48 inches
48-10=38
It just has to equal 90° so that they are parallel so 16x-6=90
16x=96 (add 6 to both sides)
x=6(divide by 16)
Which function has an inverse that is also a function? {(–1, –2), (0, 4), (1, 3), (5, 14), (7, 4)} {(–1, 2), (0, 4), (1, 5), (5,

Answer:
C. {(–1, 3), (0, 4), (1, 14), (5, 6), (7, 2)}
Step-by-step explanation:
I just did the quiz. Basically all you do is switch the x and y values for each coordinate pair in order to see if it would pass the line test. If it has double X values, it is not a function with an inverse function.
