d/dx cot(x) = -csc²(x)
d/dx sin(x) = cos(x)
So, if f(x) = 4 cot(x) + 10 sin(x), then
f '(x) = -4 csc²(x) + 10 cos(x)

The atomic weight of the new element is simply the weighted average of the isotopes. So
0.4030 * 296.78 + 0.5970 * 300.88
= 119.60234 + 179.62536
= 299.2277
Now the number of significant digits is the same as the number of significant digits of the LEAST PRECISE DATUM. And that would be the percentages at 4 significant digits each. So the result needs to be rounded to 4 significant digits which is 299.2</span>
Answer:
1.08%
Step-by-step explanation:
When you solve problems like these you convert the percentages into fractions and multiply them together.
18%= 18/100 reduced------> 9/50
6% = 6/100 reduced------> 3/50
3/50 * 9/50 = 108/10000 reduced -------> 54/5000 reduced---->
27/2500. The probability is 27/2500, or 1.08%
B: $8.75 :)))))))))))))))))))))
urrrrrrrrrrr....... bro why you bully
