In the question <span>The _____ appears in the equation of a line as the coefficient of the variable x. it is.(slope)</span>
Answer:
D
Step-by-step explanation:
Using the law of sines in ΔABC, then
= 
Substituting in values gives
=
( cross- multiply )
c × sin38° = 25 × sin31.6° ( divide both sides by sin38° )
c =
≈ 21.28 → D
The answer would be C) 5 because 2, 12a, 7b, 9a, and 14 are the terms and there are 5 of them
Answer:
See Below
Step-by-step explanation:
The standard form of an equation of a circle is:

and
(h,k) is the center
r is the radius
Changing the values of h and k changes the location of the center of the circle. Changing the value of r changes the radius and hence the "size" of the circle. Very simple!
So, basically changing h and k translates the circle elsewhere and changing r transforms (make larger or smaller) the circle!
