Answer:

If you connect A to E to D to C to B to A again it is a polygon. A to E to B to a again is also a polygon. D to E to B to C to E again is a polygon. A to E to C to B to A again is a polygon.

If the original number is 15 and the new number is 5, what is the percent decrease?
Arlecino [84]
When a quantity grows (gets bigger), then we can compute its PERCENT INCREASE:

[beautiful math coming... please be patient] <span><span>PERCENT INCREASE=<span><span>(new amount−original amount)</span>original amount</span></span><span>PERCENT INCREASE=<span><span>(new amount−original amount)</span>original amount</span></span></span>

Some people write this formula with <span><span>100%</span><span>100%</span></span> at the end,
to emphasize that since it is percent increase, it should be reported as a percent.

So, here's an alternate way to give the formula:

<span><span>PERCENT INCREASE=<span><span>(new amount−original amount)</span>original amount</span>⋅100%</span><span>PERCENT INCREASE=<span><span>(new amount−original amount)</span>original amount</span>⋅100%</span></span>

Recall that <span><span>100%=100⋅<span>1100</span>=1</span><span>100%=100⋅<span>1100</span>=1</span></span> .
So, <span><span>100%</span><span>100%</span></span> is just the number <span>11</span> !
Multiplying by <span>11</span> doesn't change anything except the name of the number!
Hope this helps

compute the value of the discriminant and give the number of real solutions of the quadratic equation. -2x²+3x+5=0
SCORPION-xisa [38]

Given a quadratic equation in standard form

y=ax^2+bx+c

The discriminant D

D=b^2-4ac

tells the types of roots the equation has.

In this case, we have

\begin{gathered} -2x^2+3x+5=0 \\ a=-2 \\ b=3 \\ c=5 \end{gathered}

Then, the discriminant of this quadratic equation will be

\begin{gathered} D=b^2-4ac \\ D=(3)^2-4(-2)(5) \\ D=9+40 \\ \mathbf{D=49} \end{gathered}

Finally, the value of discriminat is 49 and as he discriminant is greater than zero then this quadratic equation has 2 different real solutions.

Step by step solution help me pls
Ilia_Sergeevich [38]

Step-by-step explanation:

Recall that

1 + \tan^2 x = \sec^2 x

and

\dfrac{d}{dx}(\tan x) = \sec^2 x

so that

\displaystyle \int \tan^2 x = \int (\sec^2 x - 1)dx

\:\:\:\:\:\:\:\:\:=\int \sec^2 xdx - \int dx

\:\:\:\:\:\:\:\:\:=\tan x - x + C

where C is the constant of integration.
