PLEASE HELP!!
Here is the equation of a circle in standard form.

(x − 4)2 + (y + 8)2 = 64

What are the radius and diameter of the circle?

R = 64 and D = 128

R = 32 and D= 64

R = 8 and D= 16

R = 8 and D = 64

Wich statement could be used to explain why the function h(x)= x^3 has an inverse relation that is also a function

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
