Mathematics
1 answer:
Dovator [93]3 years ago
6 0

Answer:

Parallelogram = 2 pairs of parallel sides and opposite angles are equal

Triangle BEA and triangle DFC are equivalent by side angle side

Therefore, angle DCF is equivalent to angle BAE

Angles FEB and DFE are right angles due to them being supplementary angles with angles BEA and DFC, respectively.

This means triangles BEC and DFA are equivalent.

This means angles FCB and EAD are equivalent, which means angles BCD and DAB are equivalent.

This also means angles ABC and ADC are equivalent.

Opposite angles equivalent = parallelogram

According to all known laws
of aviation,


there is no way a bee
should be able to fly.


Its wings are too small to get
its fat little body off the ground.


The bee, of course, flies anyway


because bees don't care
what humans think is impossible.

KiRa [710]

Answer:

Therefore the population will be maximum when x=30 inches.

Step-by-step explanation:

Given that, the mosquito population is a function of rainfall and can be approximated by the formula

N(x)= -x^3+45x^2+1000

where x is the number of inches of rainfall.

N(x)= -x^3+45x^2+1000

Differentiating with respect to x

N'(x)= -3x^2+90x

Again differentiating with respect to x

N''(x)=-6x+90

Now we set N'(x)=0

-3x^2+90x=0

\Rightarrow -3x(x-30)=0

\Rightarrow x=0,30

N''(0)=-6.0+90=90>0

N''(30)=-6.30+90=-90

Since at x=30, N''(x)<0, So at x=30, N(x) has maximum value.

Therefore the population will be maximum when x=30 inches.

Can you think of three examples of real world parallel and/or perpendicular lines? Explain why they are important in the real-wo
Naddika [18.5K]

Answer: The road, crucifix/cross, sidewalks, railroads, and so much more.

Step-by-step explanation: Roads are parallel so that everyone can get to the same place in different lanes. This is important because lines that aren't parallel will inevitably meet, meaning that a highway would eventually merge its two lanes. This happens, but most of the highway is parallel. The same is true of sidewalks and railroads. The crucifix/cross is a Christian symbol, and while I'm not Christian, I'm sure it's important to a lot of people who are.
