The arcsin function returns an angle value.

The hyperbolic sine expresses the ratio of the distance from a point on a hyperbola to a coordinate axis to that point's distance from the origin.

9 kg = 9000 g    .....so......

9000g : 36g =  250 : 1

a^m * aⁿ = a^m+n

a^-b = 1 / a^b

The polar form is given by

z = r (cosΘ +  i * sinΘ )

r = √(3^2 + (-2)^2 ) = √(9 + 4) = √13 = 3.61

Θ = tan^-1 (-2/3) = -33.69° = 326.31°

So we have

z = 3.61 (cos 326.31° + i * sin 326.31°)

"A" is correct

(4y-3)^3   using a binomial expansion, we have

(4y)^3 - (3)(4y)^2*3 + (3)(4y)(-3)^2 - 27 =

64y^3 - 144y^2 + 108y - 27

log 2 + log (2x) = 2    by a log property, we have

log (2 * 2x)  = 2 

log( 4x) = 2

This says, exponentially, that 

10² = 4x

100 = 4x      divide both sides by 4

25 = x

15 meters = 1500 cm

And the length of the model is 1/75th of this....so...

1500/75 = 20 cm

The probability of rolling any number on any particular throw is 1/6.

So...the probability of throwing a 2 and then a  3 = 1/6 * 1/6 = 1/36.

Well...if you wanted to use "2," for example...  just key in ....  3(2) - 1
