iren2701 [21]

Answer:

Last year the cost was $28.

This year the cost is $36.

$36 - $28 = $8

Percent of increase = amount of increase ÷ original amount

$8/$28 = $0.286

$0.286 · 100 = 28.6%

There has been a 28.6% of change in the cost.

Write the following in terms of sin θ only.<br> cot θ

sveta [45]

$\bf cot(\theta)=\cfrac{cos(\theta)}{sin(\theta)}
\\\\\\
sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta)
\\\\\\
cos(\theta)=\pm\sqrt{1-sin^2(\theta)}\\\\
-----------------------------\\\\
cot(\theta)=\cfrac{cos(\theta)}{sin(\theta)}\implies cot(\theta)=\cfrac{\pm\sqrt{1-sin^2(\theta)}}{sin(\theta)}$
