(-1,4) and (3 1/64)
I took the test like 5 minutes ago.
I hope this helps!
Answer:
Rohit takes 4 4/5 minutes ( =4.8 minutes) to make a complete round of a circular park. For finishing 15 rounds, he needs time T:
T = 15 x 4.8 = 72 minutes
Hope this helps!

Answer:
10 hours
Step-by-step explanation:
Because if u divide the speed t= 4320miles/432mph=10h
Answer:
A. Sin 2x
Step-by-step explanation:
This is a trig function and has the shape of sine or cosine. Since it intersects at (0,0), it is likely a sine graph. A normal sine graph starts at (0,0), crests up at 1, and crosses back down at the x-axis at (3.14, 0). However, this graph starts at (0,0) and crosses back again at half that value. This graph has been horizontally compressed by multiplication of a number greater than 1. So this graph is Sin 2x.
Let AB and CD be two equal chords on the circumference. If you consider the triangles AOB and COD, where O is the center of the circumference, you have:
- AO = CO, because they're both radii
- BO = DO, for the same reason
- AB=CD, given
So, the two triangles have the same side, and are congruent by the SSS theorem.
This implies that they also have the same angles, and in particular, the angles AOB and COD are the same.
