"<span>z˄2 − 3" because x squared is z^2, and 3 less of it would mean to subtract it from 3</span>
Well tan x has asymptotes every 90 degrees, or in radian mode, every pi divided by two. since cot is the inverse and the aymsptotes land on every 180 degrees, meaning the equation can be x ≠ \pi n, nEI
.5(20x-50y+36)-.25(-100x+40y-12)

Discount = original price - discount price = 109 - 100.28 = 8.72 discount rate = discount/original price = 8.72/109 =0.08 = 8% answer

Answer:
total: 2.85 hours = 2 17/20 hours
Step-by-step explanation:
<u>Strategy</u>: convert all fractions to decimals, determine weeding and mowing times, and add the three times to find the total.
3/4 = 0.75
1/5 = 0.2
<u>Solution</u>:
raking time: 0.75 hours
weeding time: 0.75 +0.2 = 0.95 hours
mowing time: 0.95 +0.2 = 1.15 hours
__
Total time: 0.75 +0.95 +1.15 = 2.85 hours = 2 17/20 hours
_____
<em>Additional comment</em>
You may recognize that 0.95 is the middle of three equally-spaced values. Then the total will be 3×0.95 = 2.85 hours.
