C. Both options A and B will allow him to meet his goal.
Looking at Drake's situation after 4 weeks, he only has $470 saved. By
his original plan, he should have had $500 saved. So he's $30 short of
his goal and has 2 weeks until his originally planned class. If he goes
with option A and takes the later class, he will save an additional $125
which is more than enough to make up the $30 short fall. So option A
will work for him to save enough money for his class. With option B, he
will save $140 for the last 2 weeks of his plan giving him a savings of
$280 for the last 2 weeks. Adding the $470 he's already saved will give
him a total savings of $470 + $280 = $750 which is enough for him to
attend his class. So option B will also allow Drake to attend his
desired class. Both options A and B allow him to meet his goal. Hence,
the answer is "c".
The number of hours that students have to work on homework will be 1/3 hours.
<h3>What is subtraction?</h3>
It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.
Mr. K's maths class is 1 and 1/4 hours long.
After working problems on the board for 55 minutes or 11 / 12 hour.
He gave the students the rest of the class period to work on homework.
Then the number of hours that students have to work on homework will be
⇒ 1 + 1/4 - 11/12
⇒ 5 / 4 - 11/ 12
⇒ (15 - 11) / 12
⇒ 4/12
⇒ 1/3 hours

Answer:
The result of the integral is ![-\frac{\cos^3{10x}}{30} + C](https://tex.z-dn.net/?f=-%5Cfrac%7B%5Ccos%5E3%7B10x%7D%7D%7B30%7D%20%2B%20C)
Step-by-step explanation:
We are given the following integral:
![\int \sin{(10x)}\cos^{2}{(10x)} dx](https://tex.z-dn.net/?f=%5Cint%20%5Csin%7B%2810x%29%7D%5Ccos%5E%7B2%7D%7B%2810x%29%7D%20dx)
I am going to solve by substitution, using
, so
. So, we have
![-\frac{1}{10} \int u^2 du](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B10%7D%20%5Cint%20u%5E2%20du)
Which has the following result:
![-\frac{u^3}{30} + C](https://tex.z-dn.net/?f=-%5Cfrac%7Bu%5E3%7D%7B30%7D%20%2B%20C)
Going back to x, the result of the integral is
![-\frac{\cos^3{10x}}{30} + C](https://tex.z-dn.net/?f=-%5Cfrac%7B%5Ccos%5E3%7B10x%7D%7D%7B30%7D%20%2B%20C)
We can't match events with probability if there is no events... do you have the events?
