If f(x) = x/2 plus 8 what is f(x) when x = 10

kicyunya [14]

$f(x)=\frac{x}{2}+8$

Given y = f(x)

Substitute x = 10.

$f(10)=\frac{10}{2} +8\\f(10)=5+8\\f(10)=13$

Therefore f(x) = 13 when x = 10

Write the equation of circle with diameter of 10 units centered at (- 2, 1) .

kvasek [131]

Answer:

$(x+2)^2 + (y-1)^2 = 25$

Step-by-step explanation:

We want to write the equation of a circle with a diameter of 10 units centered on (-2, 1).

Recall that the equation of a circle has the standard form:

$(x-h)^2 + (y-k)^2 = r^2$

Where (h, k) is the center and r is the radius.

Since our diameter is 10, our radius is 5.

And since the center is at (-2, 1), h = -2 and k = 1.

Substitute:

$\displaystyle (x - (-2))^2 + (y - (1))^2 = (5)^2$

And simplify. Hence, our equation is:

$(x+2)^2 + (y-1)^2 = 25$
