Answer:
C: (-8,3) R:5
Step-by-step explanation:
The equation of a circle can be written as:
(x-h)^2+(y-k)^2=r^2
where (h,k) is the center, and r is the radius
We have the equation:
(x+8)^2+(y-3)^2=25
Center:
The center is (-8,3)
(x+8)^2--> (x-h)^2
Therefore the x coordinate of the center is -8
(y-3)^2-->(y-k)^2
Therefore the y coordinate of the center is 3
Radius
r^2=25
Take the square root of both sides
r=5
Well when you multiply it, it would equal 90 and 5*18 is 90 then you subtract 40 and you would get 50
SO YOUR ANSWER IS >>18<<
Answer:
That's math for you.
Step-by-step explanation:
Answer: The answer is (c) 3 - 4i.
Step-by-step explanation: We are given a point located on the complex plane and we are to select the correct complex number that is represented by this point.
We can see that the co-ordinates of the point on the plane are (3, -4).
Since the point (a, b) can be written in the form a + bi, where 'a' is the measurement along X-axis and 'b' is the measurement along Y-axis, so the point (3, -4) an be written in the following form:
(3, -4) = 3 + (-4)i = 3-4i.
Thus, (c) is the correct option.
Step-by-step explanation:
rational words are the words which can be expressed in a/b form whereas irrational is just opposite eg 17 ,-34
Exponential equations are equations in which variables occur as exponents. For example, exponential equations are in the form ax=by .
