Meredith invested $5,500 into an account that earned 5% interest per year. when she cashed out the investment to use it as a down payment for a new car, it was worth a total of $7,739.05.

which equation describes meredith's investment based on t, the number of years she kept the account open?

a: t=7,739.05 (5,500)^0.05

b: 7,739.05=5,500(1.05)^t

c: t=7,739.05 (5,500)^1.05

d: 7,739.05= 5,500(0.05)^t

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
