Nady [450]

Answer: I(x)=12x

Step-by-step explanation:

Let I represent the total money earned

Let x represent the number of toys sold

Since each toy is 12 dollars, then the company will earn 12 dollars for each toy that is sold.

Therefore,  the equation is,

I(x)=12x

So I'm in an online class of geometry and one of the units is trig. but no matter how long i keep learning or trying to learn th
Arturiano [62]

Answer and explanation:

There are six main trigonometric ratios, namely: sine, cosine, tangent, cosecant, secant, cotangent.

Those ratios relate two sides of a right triangle and one angle.

Assume the following features and measures of a right triangle ABC

  • right angle: B, measure β
  • hypotenuse (opposite to angle B): length b

  • angle C: measure γ
  • vertical leg (opposite to angle C): length c

  • horizontal leg (opposite to angle A): length a
  • angle A: measure α

Then, the trigonometric ratios are:

  • sine (α) = opposite leg / hypotenuse = a / b
  • cosine (α) = adjacent leg / hypotenuse = c / b
  • tangent (α) = opposite leg / adjacent leg = a / c

  • cosecant (α) = 1 / sine (α) = b / a
  • secant (α) = 1 / cosine (α) = b / c
  • cotangent (α) = 1 / tangent (α) = c / b

Then, if you know one angle (other than the right one) of a right triangle, and any of the sides you can determine any of the other sides.

For instance, assume an angle to be 30º, and the lenght of the hypotenuse to measure 5 units.

  • sine (30º) = opposite leg / 5 ⇒ opposite leg = 5 × sine (30º) = 2.5
  • cosine (30º) = adjacent leg / 5 ⇒ adjacent leg = 5 × cosine (30º) = 4.3

Thus, you have solved for the two unknown sides of the triangle. The three sides are 2.5, 4.3, and 5.

Which numbers are rational? select all that apply. A. pi B. √50 C. 2.3 D. √144
aev [14]
C. 2.3
D.√144


Rational roots or decimals are numbers that have an end point. 

pi 'technically' never ends, while √50 = 7.07106781<span>…, which never ends either

hope this helps
