Answer:
Blue is linear
Step-by-step explanation:
For lines to be linear on a graph, they have to follow these 2 rules:
-be a straight line
-be written in the form of y=mx+b
Therefore, blue is linear and orange is nonlinear
Answer:40 is permiter
Step-by-step explanation:
A pentagon has five sides
8+8+8+8+8=40
Answer:
t=0
Step-by-step explanation:
r=<+1,>
by differentiating the r vector component by component
r' = <2at, 1>
Two vector are orthogonal when the dot product between them is zero, so:
r'·r=0
<+1,>·<2at, 1>=2+2at+t=0
common factor
t(+2a+1)=0
Then, the only real value for t is zero.
-> t=0
