Cos = adjacent / hypotenuse
cos B = 4/5
B = cos^-1 (4/5)
B = 36.869897....
B = 36.87° (nearest hundredth)
Angle B = 36.87°.
12 oz for 2.68 = .22 per unit
16 oz for 2.49 = .16 per unit
the 16 oz for 2.49 is your better deal
Radio was 10
got markup of 54%
this implies it is almost 1/2x more than 10
10*1 is 100% of 10
use this fact and take 10 + .54*10=New Cost (nc)
tax is 2% use nc*1.2
Answer:
36 milliliters of rain.
Step-by-step explanation:
The rate at which rain accumluated in a bucket is given by the function:

Where r(t) is measured in milliliters per minute.
We want to find the total accumulation of rain from <em>t</em> = 0 to <em>t</em> = 3.
We can use the Net Change Theorem. So, we will integrate function <em>r</em> from <em>t</em> = 0 to <em>t</em> = 3:

Substitute:

Integrate:

Evaluate:

36 milliliters of rain accumulated in the bucket from time <em>t</em> = 0 to <em>t</em> = 3.
Should be clear (more or less) that if the pattern continues, it is NOT repeating
repeating would be something like <span>0.112211221122...</span>
