Step-by-step explanation:

x cos θ + y sin θ = x cos β + y sin β

Let's say x = cos A, and y = sin A.

cos A cos θ + sin A sin θ = cos A cos β + sin A sin β

Use angle sum formula.

cos(A − θ) = cos(A − β)

A − θ = ±(A − β)

A − θ = β − A

2A = θ + β

A = (θ + β) / 2

cot A = cot((θ + β) / 2)

x/y = cot((θ + β) / 2)

Rewrite to make it easy to graph using a translation. Describe the graph: 3√(27x-81) - 5

Kipish [7]

Numbers 27 and 81 have 27 as common factor which is equal to 3^3. Noting that we can put 27 before brackets write it in form 3^3 and that third root and cube will trim.

$\sqrt[3]{27x - 81} - 5=$
$\sqrt[3]{27(x-3)} - 5 =$
$\sqrt[3]{3^3(x-3)} - 5=$
$3 \sqrt[3]{x-3} - 5$

-5 means that graph is shifted 5 to down.
-3 means it is shifted to right by -3
3 and ∛ represent scaling of graph which can be seen and tested once you draw it. It is harder to explain it with words.

during the summer each student got 5% taller erik is 151.2 cm taller after the summer how tall was be before the summer?

storchak [24]

You have to multiply 151.2 X 5% =7.56
Then you subtract 151.2 - 7.56
Before the summer he was 143.64cm
