Convert (-2/sqrt[3] , 2) to polar coordinates

1 answer:

5 0

If you have these conditions:

1. (r ,theta) where r > 0
2. (r, theta) where r < 0

The solution would be:

r = sqrt(x^2 + y^2)

t = arctan(y/x)

r = sqrt(12 + 4) = sqrt(16) = +/- 4

t = arctan(2 / -2sqrt(3)) = arctan(-1 / sqrt(3)) = 5pi/6 , 11pi/6

1)
r > 0
(4 , 11pi/6)

2)
r < 0
(-4 , 5pi/6)

Answer:

$(f\circ g)(4)=31$

Step-by-step explanation:

Composite Function

Given f(x) and g(x) real functions, the composite function named fog(x) is defined as:

$(f\circ g)(x)=f(g(x))$

For practical purposes, it can be found by substituting g into f.

We have:

$f(x)=3x+1$

$g(x)=x^2-6$

Computing the composite function:

$(f\circ g)(x)=f(g(x))=3(x^2-6)+1$

Operating:

$(f\circ g)(x)=3x^2-18+1$

Operating:

$(f\circ g)(x)=3x^2-17$

Now evaluate for x=4

$(f\circ g)(4)=3(4)^2-17=48-17$

$\boxed{(f\circ g)(4)=31}$

Sally has 2 cats and each cat eats 1/4 of a tin of cat food each day.

Mashutka [201]

If one cat eats 1/4 of a tin per day then two cats eat 1/2 of a tin per day.

We have 9 tins so if each day cats eat 1/2 we have to divide 9 with 1/2 and we get 18 which is for how many days she can feed the cats until she runs out of food.

Hope this helps.
