Thanks bob bundy!
In Q1,using integration, I got the same answer as when I plugged in the values in the position function you gave but could you still
check my solution for any flaw?
Here it is:
Given that speed=10 and since speed=absolute value of velocity, v=-10
Hi! Help please.
A ball was thrown downward from the top of a building at a speed of 10 meters per
second and it hit the ground 3 seconds later. How tall was the building? [Note: Use
-10 m/s² for acceleration due to gravity.]
>>Here's what I think I should do:
1. Find the velocity then position functions
Here's what I got:
[Note: C*=constant after integrating a(t) and C**= constant after integrating v(t)]
2.Find the value of C* and C**
My question: is it right to use these: v(3)=0 and s(3)=0 to find them?
The base of a solid S is the region bounded by y =square root of (16-x²) and the x-axis, and each
cross-section perpendicular to the x-axis is an isosceles right triangle having one leg on
the base of S. Using the method of slicing, determine the volume of S.
>>I have a hard time with this problem. A help on visualizing the figure and/or setting-up the integral that will give the volume would do.
I tried to read about the L'Hopital's rule but I found out that for me to use that rule, I need to learn to evaluate derivatives.I must agree that the with the use of the rule, the solution would be simpler but may I ask for a solution without using that rule? It is because we are not yet on derivatives and I think the purpose of the problem, being included in the practice exercises of the topic that introduces limits, is for us to be able to master the basic theorems about limits that we had just learned.
Hi! Please, help me with this one:
Evaluate the limit of (3-x)/(3-(sqrt of (6x-x²)) as x approaches 3 from the left.
What I did was this: I substitute 3 and found out that what I have is an indeterminate form of type 0/0. I then tried rationalizing the denominator but after it, I still arrived at the the same indeterminate form.
If what I did was right, please let me know the next step to solve the problem. If not, I'd like to ask for the right solution. I'll be waiting for replies then. Thanks in advance!
Whooh! Seems like you're an avid reader of mangas.
I'll tell my brother about the Death note's manga.
I'm sorry cause I'm about to log-out now. Its because I'm going to prepare for my class later. It's been nice knowing more of you!
Bye-bye for now and until next time!
Have a great day ahead!
Same here. I think I'm only one of the few teens who is not yet that hooked in mangas and animes.But last week, I watched Princess Mononoke and I liked it. I have a brother who really love anime. I have heard him telling how good Death Note is. He also liked Fairy Tail and Reborn.
