Iput 2500 in the bank at 8% intrest for 15 years. how much intrest will i earn over that time?

Principal amount invested = 2500
Rate of interest given = 8%
Time for which the money is kept = 15 years
Then
Interest = Principal * Rate * Time
             = 2500 * 4% * 15
             = (2500 * 4 * 15)/100
             = (25 * 4* 15)
             = 1500
So the interest gained by me is 1500. I hope this is the answer you were looking for and the procedure for doing the problem is clear to you. In future you can do such problems without requiring any help.

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
