In circle M, diameters JL and HK each measure 16 centimeters.
1 answer:
Answer:
3.5 cm
Step-by-step explanation:
Length of an arc is a "part" of the circumference of a circle.
The circumference is the perimeter of the circle. Formula is:
Where
C is circumference
d is diameter
Given diameter is 16, the circumference would be:
Now, the arc is 25 degrees, which is 25/360 th of the circle's circumference [recall, there is 360 degrees in whole circle].
So, we multiply the circumference we got by (25/360) to get our answer:
Minor Arc JH = 3.5 cm

Answer:
The value of x = -1 makes the denominator of the function equal to zero. That is why this value is not included in the domain of f(x)
Step-by-step explanation:
We have the following expression
Since the division between zero is not defined then the function f(x) can not include the values of x that make the denominator of the function zero.
Now we search that values of x make 0 the denominator factoring the polynomial
We need two numbers that when adding them get as a result -1 and when multiplying those numbers, obtain -2 as a result.
These numbers are -2 and 1
Then the factors are:
We do the same with the numerator
We need two numbers that when adding them get as a result 4 and when multiplying those numbers, obtain 3 as a result.
These numbers are 3 and 1
Then the factors are:
Therefore
Note that only if
So since is not included in the domain the function has a discontinuity in
