(Please I really need help) Which equation represents the number of years (t) that it takes $200 to grow to $500 if it is
growing at an exponential rate of 15% per year?
A. 500 = 200(0.15)^t
B. 500 = 0.15(200)^t
C. 500 = 200(1.15)^t
D. 500 = 1.15(200)^t

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

it would be 6xy and -16xy.
