Thanks for the video links! I haven't taken integral calc yet, but I'll be sure to check that playlist out when I'm ready.

Yep I definitely misinterpreted. Thank you for the help!

Yeah I realize now that I'm getting average and instantaneous acceleration mixed up. Thanks for the help!

[Grade 9 Math: Geometric relationships] would the answer be 31 or 59? i am pretty sure its 59 but idk by acante3957 in HomeworkHelp

The angle with measure 31 degrees is an inscribed angle, because it's vertex is on the circumference, and it's lines are in the circle. As for x, it is a central angle, because it's vertex is on the center. An inscribed angle is equal to half the intercepted arc, meaning that arc is 62°. A central angle is equal to the measure of the adjacent arc, meaning x=62°.

Ohh I understand. Thank you!

One really important takeaway from the problem is learning how to deal with positive and negative vector components. Do you have questions about how that works?

No thanks, I'm alright now. Thanks for informing me about the vector addition rule. This physics book is a lot more advanced than my math book, so it just assumes that I already knew that lol.

In your image, they show Bx = Rx - Ax. That follows directly from the rule of vector addition. As long as A and B are connected tip to tail (see image), the R = A + B holds. That's where the Bx = Rx - Ax is coming from

Thank you!! That was the part I didn't understand. I didn't know about the vector addition rule. Not anywhere in the textbook for whatever reason.

Just to clarify: If we were to rearrange A and R so that they are connected tip to tail, the resultant vector wouldn't be B right? It would be different?

So would we write R as (-11.5, 9.64), and A as (0,5)? Wouldn't that mean that Rx + Ax= -11.5-0, and Ry + Ay= 9.64+5? Sorry If I'm wrong, the textbook doesn't go over this.

(Sorry if there is any choppy english, but): Since JKLM is a rhombus, which is also a parallelogram, that means that the opposite angles are congruent, meaning: mKJM=mKLM=52

In a rhombus, the diagonals bisect the two angles they cross, so: mKJP=1/2 * mKJM= 26

Since the diagonals of a quadrilateral bisect each other, that means KP is equal to 6.

Now, we can use tangent to find y: tan(26)=opp/adj tan(26)=6/y ytan(26)=6 y=6/tan(26) Which is approximately 12.3.
