Answer:
Triangle B
Step-by-step explanation: Look at the square figure on one of the corners. That means that your triangle is a right triangle, which means, its measurement on that corner is 90 degrees
Answer:
7
r
Step-by-step explanation:
-1.3
2.9-0.6r
-2.9 -2.9
-4.2 ≥ -0.6r
/-0.6 /-0.6
7 ≥ r
The left sum would be f0+f1+f2+f3
The right sum would be f1+f2+f3+f4
The trapezoidal rule value is:
(f0+f1)/2 + (f1+f2)/2+(f2+f3)/2 +(f3+f4)/2
This would put the trapezoidal rule in the middle , which makes the answer:
Lower sum < Trapezoidal rule Value < Upper sum
Answer:

Step-by-step explanation:
Given

Rotation = +270 degrees
Required
Determine the new coordinates of Q (i.e. Q')
When a point (x,y) is rotated +270° about the origin, the new coordinates is: (y,−x)
So:

Where:
and 
Q' will be:
