If a=4b^2 and b=-1/2e^2, what is the value of a to the nearest tenth?
Maru [420]
To answer, it is assumed that e here is the Euler number which is equal to 2.718. Substitute this value to the e of the second equation to get the value of b.
                                 b = 0.5(2.718^2)  = 3.6945
Then, we substitute this value to the first equation to get the value of a.
                                        a = 4(3.6945^2) = 54.498
Thus, the answer is approximately equal to 54.5.

Points A,B, and C are collinear. Points M and N are the midpoints of segments AB and AC. Prove that BC = 2MN
irinina [24]
Look at the picture.

1)|AM| = |MB| = x
|AN| = |NC| = y
|BC| = 2y - 2x = 2(y - x)
|MN| = y - x
Therefore |BC| = 2|MN|
2)|AM| = |MB| = x
|AN| = |NC| = y

|BC| = 2y - 2x = 2(y - x)
|MN| = y - x
Therefore |BC| = 2|MN|

What is the solution to this equation 1^6 x =2
Alenkinab [10]
<h2>Greetings!</h2>

Anything to the power of 1 is still 1, because 1^{6} is simply 1 x 1 x 1 x 1 x 1 = 1 ect.

<h3>So this changes the equation to 1x = 2, which means that:</h3>

x = 2

<h2>Hope this helps!</h2>
