(1, 1/2, 1/3, 1/4, ...)

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.

PLEASE HELP RIGHT AWAY!!

Katen [24]

Answer:

$17.35/h

Step-by-step explanation:

In order to get the amount per hour he made, you first need to calculate the global amount of money he made.

He was paid $2,900 then he had costs of $1,200, that leaves him a net income of $1,700 ($2,900 - $1,200)

Then he worked a total of 98 hours for that money.

A salary is an amount of money expressed by a period of time. In this case, we'll use hours.

So, Jonah earned $1,700 after 98 hours of work:

S = $1,700 / 98 hours = $17.35/h

Hi, can someone please help me out with this problem? thanks in advance.

Answer:

The following is an income statement using the Contribution format.

...........................Income Statement for Rivieremia Corp................................

Sales ........................................................................$1,500,000

Less Variable Costs................................................($1,200,000)

Contribution Margin..............................................$300,000

Less Fixed Costs....................................................($200,000)

Operating Income .................................................$100,000

Less Tax....................................................................($10,000)

Net Income...............................................................$90,000

Tax = 10% * 100,000 = $10,000

Proving breakeven is $1,000,000.

The breakeven point for a company can be calculated by dividing the Fixed cost by the contribution margin ratio.

Contribution margin ratio = Contribution margin / Sales

= 300,000/1,500,000

= 20%

= Fixed Cost/ Contribution Margin ratio

= 200,000/20%

= $1,000,000

Degree of Operating Leverage = Contribution Margin/ Operating Income

= 300,000/100,000

= 3

4(3x+2y) distributive property pls help

Sonbull [250]

Answer:

$12x+8y$

Step-by-step explanation:

1) Expand by distributing terms.

$4*3x+4*2y$

2) Simplify 4*3x to 12x.

$12x+4*2y$

3) Simplify 4*2y to 8y.

$12x+8y$

Therefor, the answer is 12x + 8y.
