When we speak of the word "perimeter" of a circle, we mean to say the circumference. Since we are only given a semicircle, the perimeter would be,
perimeter = (pi)(radius) + diameter
Substituting the known values,
perimeter = (3.14)(6 cm) + 12 cm
The value of the perimeter is,
perimeter = 30.84 cm
Answer:
Prime Numbers
Step-by-step explanation:
Two sets are being considered in the given statement:
- Set of even numbers
- Set of prime numbers
A universal set is defined as such a set from which all the other subsets are taken for a given case. Or in other words, a universal set is such a set to which all the subsets belong and this universal set contains all the elements being studied/considered.
For the given case, set of Even Numbers is the subset which is being taken from the set of prime numbers. The set of prime numbers contains all the elements which we are considering for this very scenario.
Therefore, the set of prime numbers is the universal set.
Answer:
Step-by-step explanation:
1) First, find the slope of the line. Take two points the line intersects and use them for the slope formula, . We already know the line intersects (-4, -2). Just choose any one of the points you can see the line intersecting (in this case, I chose (0,3)) and plug in its values, too. Then solve:
So, the slope is .
2) Now that you have the slope, plug in values for the point-slope formula, . In order to write a linear equation with it, the , , and have to be substituted for with real values. The represents the slope - which means that we should place there. The and represent the x and y values of a point - and the questions wants us to use (-4, -2), so substitute -4 for and -2 for :
Thus, the answer is .
