Write the standard equation for the circle 30. Center (2,7), r=4. 31. Center (-6,-8), that passes treough (0,0)

Salsk061 [2.6K]

The standard equation of the circle is:

(x-h)^2+(y-k)^2=r^2 where (h,k) it the center of the circle and r is the radius...

so

30.

(x-2)^2+(y-7)^2=16

31.

We need to find the radius...(I'll just use the Pythagorean Theorem)

r^2=6^2+8^2

r^2=36+64

r^2=100 (so the radius is 10) and its center is (-6,-8) so

(x+6)^2+(y+8)^2=100

Use f(x) = 2x-9 and g(x)=9-x^2 to evaluate g(f(3))

Keith_Richards [23]

Answer:

g(f(3)) = 0

Step-by-step explanation:

f(x) = 2x - 9

f(3) = 2(3) - 9

f(3) = -3

g(-3) = 9 - (-3)^2

g(-3) = 9 - 9

g(-3) = 0

Z=8+6x-px solve for x

ohaa [14]

z = 8 + 6x - px Subtract 8 from both sides
z - 8 = 6x - px Factor the x out of 6x - px
z - 8 = x (6 - p) Divide both sides by (6 - p)
$\frac{z - 8}{6 - p}$ = x Switch the sides to make it easier to read
x = $\frac{z - 8}{6 - p}$
