Answer:
<em>AXE</em> and <em>CXD </em>are vertical angles
<em>AXF</em> and <em>FXD </em>are supplementary angles
<em>DXC </em>and <em>BXC </em>are complementary angles
<em>EXA</em> and <em>AXB </em>are adjacent angles
<em>AXC </em>and <em>CXD</em> are supplementary angles
<em>EXD </em>and <em>AXC </em>are vertical angles
Step-by-step explanation:
1) the car has travelled 210 miles in 3.5 hours
2) No because the line stops at (1,50)
A ) 5x^3 - 6x^4
B ) 11x^4 - 13x^3
C ) 14^x3 - 2x^4
D ) 2x^4 - 12x^3
E) 5x^4 - 3x^3
I believe this is all right!
If <em>f(x)</em> is a density function, then its integral over the entire real line should be 1:

so yes, <em>f(x)</em> is indeed a density function.
