It should be 13 as well
Because the arc length of CDE and ABCD are both 90 degrees. They share 20 degrees from arc CD and they already both have 70 degrees. So if the arc length is equal, the corresponding chords should be equal too.
Answer:
-8 a
Step-by-step explanation:
i simplified -3 a (70+3a) wich came out to negative eight A
Answer: The first option is correct.
Explanation:
The given piecewise function is,

From the piecewise function we can say that if x<0, then

If
, then

Since the f(x) is defined for x<0 and
, therefore the function f(x) is not defined for
.
In the graph 2, 3 and 4 for each value of x there exist a unique value of y, therefore the function is defined for all values of x, which is not true according to the given piecewise function.
Only in figure the value of y not exist when x lies between 0 to 2, including 0. It means the function is not defined for
, hence the first option is correct.
3.2/64 is .05 rounded to the nearest 10th is .1
