Assuming cashflows occurring in year t (Ft), and a single discount rate in decimal (r), the present value P is given by: P = St ( Ft / (1+r)t ) For example, the net present value the cashflows [20, 50, 90] discounted at a rate of 5% is: P = 20 / (1.05) + 50 / (1.05)2 + 90 / (1.05)3 = 142.14 (rounded to 2 decimal places) Assignment: Write a function NetPresentValue(flowlist, rate) that takes a list of values, and an interest rate (in decimal), and returns the net present value. The list of values is assumed to be annual flows, so for example, [10, 20] represents a flow of 10 at end of year 1, and 20 at end of year 2. Zero is a valid value, so for example, [0, 20] represents no flow at the end of year 1, and a flow of 20 at the end of year 2.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

50.6

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
