Which one is an exponential function

B k(x) = 2⁽⁻²ˣ⁾

D g(x) = 5ˣ

Step-by-step explanation:

A h(x) = 2 + 0.25x   nope

C f(x) = I don't know how to represent the summing of previous totals to the next odd number.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

to complete this square you have to rotate about the origin 270 degrees clockwise.
