If tan e = 1.3, what is the value of cot (90° - 9)?

ella [17]

Answer:

A

Step-by-step explanation:

We are given that:

$\tan(\theta)=1.3$

And we want to find:

$\cot(90^\circ -\theta)$

Remember that tangent and cotangent are co-functions. In other words, they follow the cofunction identities:

$\tan(\theta)=\cot(90^\circ-\theta)\text{ and } \cot(90^\circ-\theta)=\tan(\theta)$

Therefore, since tan(θ) = 1.3 and cot(90° - θ) = tan(θ), then cot(90° - θ) must also be 1.3.

Our answer is A.

-2 (m+n-4)+5 (-2m+2n)+n (m+4n-5)

Natalka [10]

So if you want to add
we distribute
a(b+c)=ab+ac so
-2(m+n-4)=-2m-2n+8

5(-2m+2n)=-10m+10n

n(m+4n-5)=mn+4n^2-5n

so total we ahve
-2m-2n+8-10m+10n+mn+4n^2-5n
group like terms
4n^2+-2m-10m-2n+10n-5n+mn+8
add like temrs
4n^2-12m+3n+mn+8

$A)9-8i$

Explanation

$9-\sqrt[]{-64}$

Step 1

Let's remember that

A complex number is an object of the form

$a+bi$

where a and b are real numbers and

$\begin{gathered} i^2=-1 \\ i=\sqrt[]{-1} \end{gathered}$

so

$\begin{gathered} 9-\sqrt[]{-64} \\ 9-\sqrt[]{-1\cdot64} \\ 9-\sqrt[]{-1}\sqrt[]{64} \\ 9-8\sqrt[]{-1} \\ 9-8i \end{gathered}$

therefore, the answer is

$A)9-8i$

I hope this helps you
