Suppose we apply the translation map Tv to each point on the circle (x + 4)^2 + (y − 3)^2 = 25.
1 answer:
Answer:
(-4,3) , r = 5
Step-by-step explanation:
given,
equation of circle
(x + 4)² + (y − 3)²= 25.
general equation of the circle
(x - a)² + (y - b)² = r²
comparing the given equation from the general we get,
radius = r² = 25
r = 5
-a = 4 -b = -3
a = -4 b = 3
the center of the circle is (-4,3)
hence, all the specification is shown in the image attached below

Answer: B
Step-by-step explanation:
Intersection of the 2 parts of the function is (0,0):
==> not A
the second part of the function is an half-line (and x =0)
Answer B
Keywords:
<em>System of equations, variables, hardcover version, paperback version, books </em>
For this case we must construct a system of two equations with two variables. Let "h" be the number of hardcover version books, and let "p" be the number of paperback version books. If the hardcover version of a book weighs 7 ounces and the paperback version weighs 5 ounces, to reach a total of 249 ounces we have:
(1)
On the other hand, if there are Forty-five copies of the book then:
(2)
If from (2) we clear the number of books paperback version we have:
As each paperback version book weighs 5 ounces, to obtain the total weight of the paperback version books, represented by "x" in the table shown, we multiply
So,

Option D
