What is the equations of a circle at (4,5) and a radius of 2

1 answer:

8 0

Equation of any circle with (a,b) as its center, and on (x,y) coordinate, with radius r, is:
$(x-a)^2+(y-b)^2=r^2$
so here the center is at (4,5) with radius of 2, so,
The equation of this circle is:
$(x-4)^2+(y-5)^2=4$

Hope this helps.

If f(x) is a third degree polynomial function and g(x) = f(–2x), which of the following is NOT true?

valina [46]

Answer:

f(x) and g(x) have the same x-intercepts (is <em>not true</em>)

Step-by-step explanation:

g(x) is a reflection across the y-axis and a horizontal compression of f(x). In general those transformations will move the x-intercepts. (The y-intercept and the number of x-intercepts will remain unchanged.)

_____

<em>Comment on the question/answer</em>

f(x) = x^3 is a 3rd degree polynomial. When transformed to g(x) = -8x^2, its only x-intercept (x=0) remains the same. The answer above will not apply in any instance where the only x-intercept is on the line of reflection. (The question is flawed in that it does not make any exception for such functions.)

Answer:

50.24

Step-by-step explanation:

1/4x3.14xr^2

r=16 because of the length

90/360= 1/4

1/4x3.14x16^2/4

=50.24

4 is our denominator because of the denominator on the fraction
