What way are you trying to solve
Answer:
Tags not given out=(k/5)-40
Step-by-step explanation:
k is tag
Tags k given to student are half = k/2
Tags given to parents are= 100
Total tags given to students and parents are=(k/2)+100
So remaining tags are=k-(k/2+100)
=(k-200)/2
tags given to judges and teacher are 3/5 of remaining tags =(3/5)*((k-200)/2)
So tags not given out are =(2/5)*((k-200)/2)
=(k/5)-40 Answer
You can break the integral of a sum/difference into the sum/difference of the integrals:

The first integral can be solved using the power rule for integrations:

As for the second, remember the chain of derivation of trigonometric functions:

The integration chain is the same, but it follows the opposite direction: the integral of the cosine function is the sine function. So, you have
Since this is an indefinite integral, we must add the generic costant to the answer:

Answer:
see the x and the y two times they're right there point them out
Answer:
126 in.
Step-by-step explanation:
Formula for surface area:
A = 2(wl + hl + hw)
2 · (6 · 5 + 3 · 5 + 3 · 6) = 126
