What is the center and radius of the circle with equation (x - 2)^2 + (y - 5)^2 = 100?

ololo11 [35]

Answer:
Center = (2,5)
Radius = 10
Choice A

To find this answer, first write the equation
(x-2)^2 + (y-5)^2 = 100
into
(x-2)^2 + (y-5)^2 = 10^2

Note how the second equation is in the form
(x-h)^2 + (y-k)^2 = r^2

We see that (h,k) = (2,5) is the center
and r = 10 is the radius

A parallelogram has an area of x2+ 9x− 36.

Serhud [2]

Answer:

a) Length $x + 12$ , Width $x - 3$ , b) $x = 3$

Step-by-step explanation:

a) The expressions for the length and width of the parallelogram can be determined by factorizing the polynomial:

$A = x^{2} + 9\cdot x - 36$

$A = (x+12)\cdot (x-3)$

Length

$x + 12$

Width

$x - 3$

b) Since area is a positive variable, the set of solutions encompass all values of x such that area is zero o greater. Then, there are two interval where A is positive:

- When both binomials are negative.

$x \leq 3$ and $x \leq -12$

$x \leq -12$

- When both binomials are positive.

$x \geq 3$ and $x \geq -12$

$x \geq 3$

Since x is an integer, x must be positive and therefore the least possible value of x is:

$x = 3$
