So since they mentioned tangent I am guessing you need to use sin and cosine.

Usually we use sin, cosine and tan when we have an angle and we need to find one of the sides (look at the picture below)

But since now we have the sides and we need to find the angle, we need to use something called sin inverse or arcsin.

X=sin^-1 (6/14)

Note: sin^-1 is the same as saying sine inverse same as saying arcsin.

If we use this it will give us the required angle..

X=25.377 or X=25.4 degrees

Please do yourself a favour and compare it to the one below...finding the sides (because in the case we have the angle and not the sides we don’t use sine inverse)

The amount of garbage, G produced by a city with population p is given by G = f(p). G is measured in tons per week, and p is mea
barxatty [35]
Alright, so this is simple.

P= 50,000 or 50 thousands

G= 13 Tons

The variable f isn't known.

So your equation would be 13 = 50 (f), if you were to put your known variables in the equation.

If you were to find variable f, you would divide 13 tons by 50,000 to get 0.00026 or in scientific notation: 2.6 x 10 (exponent(s):-4)

If ​f(x)equals 2xminus5 and ​k(x)equals ​f(xplus3​), write the equation for​ k(x).
ololo11 [35]
F(x)=2x-5
k(x)=f(x+3)=2(x+3)-5=2x+6-5=2x+1

k(x)=2x+1

M=-4/3, point (0,-12)
postnew [5]
Y - y1 = m(x - x1)
slope(m) = -4/3
(0,-12)....x1 = 0 and y1 = -12
sub
y - (-12) = -4/3(x - 0) =
y + 12 = -4/3(x - 0) <=== point slope form

y + 12 = -4/3x 
y = -4/3x - 12 <=== slope intercept form

y = -4/3x - 12
4/3x + y = -12
4x + 3y = -36 <=== standard form
