Lucy spent $165 in December using a new credit card. In January, she began paying between $15 and $25 each month towards her account balance. The equation f(x) = 165(0.8)x describes the curve of best fit for Lucy's account balance f(x). Let x represent the number of months since December. Month Account Balance December $165.00 January $132.00 February $105.60 March $84.48 Using the equation for the curve of best fit, what will Lucy's account balance be in June? Round to the nearest cent. A. $28.25 B. $53.95 C. $43.25 D. $33.25

The lengths of nails produced in a factory are normally distributed with a mean of 4.91 centimeters and a standard deviation of 0.05 centimeters. find the two lengths that separate the top 4% and the bottom 4%. these lengths could serve as limits used to identify which nails should be rejected. round your answer to the nearest hundredth, if necessary.

How do i simply this expression (quadratic formula basis) on a ti-84 or normal calculator?

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
