Answer: inconsistent

Step-by-step explanation:

Inconsistent systems have two lines that are two independent equations that don’t overlap. Basically, if the lines are parallel, the system will always be inconsistent.

Which statements must be true?

slamgirl [31]

Answer:

The options 2,3 and 5 are correct.

Step-by-step explanation:

From the figure it is noticed that the points U,V and W are midpoint of JK,KL and JL respectively.

Midpoints theorem of triangle states that the line connecting the midpoints of two sides is parallel to third side and its length is half of the third side.

The points U and W are midpoint of JK and JL. Using midpoint theorem, we get

$UW=\frac{1}{2}KL$

$UW\parallel KL$

The points U and V are midpoint of JK and KL. Using midpoint theorem, we get

$UV=\frac{1}{2}JL$

$UV\parallel JL$

The points V and W are midpoint of KL and JL. Using midpoint theorem, we get

$VW=\frac{1}{2}JK$

$2VW=JK$

$VW\parallel JK$

Therefore options 2, 3 and 5 are correct.

The region bounded by y=5/x, y=0, x=1, and x=3 is rotated about the x-axis. find the volume of the resulting solid.

brilliants [131]

Volume of Revolution = $\pi \int\limits^b_a {y^{2}} \, dx$
Volume of Revolution = $\pi \int\limits^3_1 { (\frac{5}{x})^{2}} \, dx$
= $\pi \int\limits^3_1 ({\frac{25}{x^{2}}) \, dx$
= $25\pi \int\limits^3_1 ({\frac{1}{x^{2}}) \, dx$
= $25\pi \int\limits^3_1 ({x^{-2}}) \, dx$
= $25\pi \ ^{3} [-x^{-1}] _{1} 
$
$= 25\pi\ ((-1/3) - (-1/1)) \\
= 25\pi\ (2/3) \\
= 50/3 \pi\ units^{3}$
