Agraduated commission employee makes 3.5% interest on the first $50,000 in sales and 6.5% interest on all sales over $50,000. which of the following expressions represents the employee’s total earnings on $81,500 in sales?

If the question is asking which of the two will be used on one sale of $81,500 then use the 6.5% but if the question is asking what he earns if the first $50,000 is subject to the first interest rate, and the rest of it to the second then the answer will be as so; he earns 3.5% on his first $50,000, this is $1,750. He still has $31,500 that is earning 6.5%, which is $2,047.5. He earns a total of $3,797.50

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
