<h3>Solution:</h3>

8 {k}^{2}  + 80k + 200 \\  = 8( {k}^{2}  + 10k + 25) \\  = 8  [{k}^{2}  + 2(k)(5) +  ({5})^{2} ] \\  = 8( k + 5) ^{2}

<h3>Answer:</h3>

8( k + 5) ^{2}

Given that Cosecant (t) = negative StartFraction 13 Over 5 EndFraction for Pi less-than t less-than StartFraction 3 pi Over 2 En
Sergio [31]

Answer:

\bold{cot(t) =\dfrac{12}{5}}

Step-by-step explanation:

Given that:

Cosec (t) = -\frac{13}5

for \pi < t < \frac{3 \pi}2

That means, angle t is in the 3rd quadrant.

To find:

Value of cot(t)

Solution:

First of all, let us recall what trigonometric ratios are positive and what trigonometric ratios are negative in 3rd quadrant.

In 3rd quadrant, tangent and cotangent are positive.

All other trigonometric ratios are negative.

Let us have a look at the following identity:

cosec^2\theta -cot^2\theta =1

here, \theta =t

So, cosec^2t-cot^2t=1

\Rightarrow (-\dfrac{13}{5})^2-cot^2t=1\\\Rightarrow (\dfrac{169}{25})-cot^2t=1\\\Rightarrow \dfrac{169}{25}-1=cot^2t\\\Rightarrow \dfrac{169-25}{25}=cot^2t\\\Rightarrow \dfrac{144}{25}=cot^2t\\\Rightarrow cot(t)=\pm\sqrt{\dfrac{144}{25}}\\\Rightarrow cot(t)=\pm\dfrac{12}{5}

But, angle t is in 3rd quadrant, so value of

\bold{cot(t) =\dfrac{12}{5}}

How many complex roots does the polynomial equation below have? x^5 - 3 = 0
const2013 [10]

For any polynomial equation, The Fundamental Theorem of Algebra tells you that the highest degree present will tell you how many complex roots the equation has. There are only two terms, "x^{5}" and "3". The x^{5} term has a degree of 5, its exponent. The 3 term has a degree of zero, because you could write it as 3 * x^{0} = 3 * 1 using the zero exponent rule.


The degrees present are 5 and 0. Choose the highest one, 5. So, the answer here is D.
