Answer:

(x+8)^2+y^2=16

Step-by-step explanation:

The equation for a circle in center-radius form is

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

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

We are given the diameter is 8 so the radius is 8/2=4.

We are also given (h,k) is (-8,0).

The equation for the circle is

(x--8)^2+(y-0)^2=4^2

(x+8)^2+y^2=16

Assoli18 [71]

Lets say the number of adult tickets is x. This means the number of student tickets is 2x. So, 2x + x = 285, or 3x =285. The means x = 95. So the number of adult tickets sold is 95.

Help with this math question please

Step2247 [10]

The base of log is 10. So raising both sides to 10, we get:

$10^{0.94} = 10^{ log_{10} x} \\ \\ 
 10^{0.94}=x \\ \\ 
x= 8.71$

S, rounding of to nearest hundredth, the value of x in the equation 0.94 = log(x) comes out to be 8.71.
