What is the image of -1 - 5 after a dilation by a scale factor of 5 centered at the origin

amm1812

the Given data

*The given point is (-1, -5)

*The given scale factor is 5

The image of -1 - 5 after dilation by a scale factor of 5 centered at the origin is given as

$(-1,-5)=(-1\times5,-5\times5)=(-5,-25)$

Thus, the image after dilation by a scale factor of 5 centered at origin is (-5, -25)

What is the simplest form of the expression below?

sineoko [7]

Answer:

(B) cot Theta

Step-by-step explanation:

We want to simplify the expression:

$\dfrac{cot\theta cos\theta}{sin\theta } X\dfrac{tan\theta}{\frac{sin\theta}{cos\theta tan \theta} }$

Now:

$\dfrac{ cos\theta}{sin\theta } =cot\theta\\\dfrac{ sin\theta}{cos\theta }=tan \theta\\$Substituting these into the expression\\\dfrac{cot\theta cos\theta}{sin\theta } X\dfrac{tan\theta}{\frac{sin\theta}{cos\theta tan \theta} }=cot\theta cot\theta X\dfrac{tan\theta}{\frac{tan\theta}{ tan \theta} }\\=cot\theta cot\theta X tan\theta$ (Since cot\theta X tan\theta =1) \\$Therefore our result:\\=cot\theta$
