Answer: choice D) 5/2

The csc or cosecant value is the reciprocal of the sine value. All you do is flip the fraction given. In terms of notation, we can say csc(theta) = 1/sin(theta). If sin(theta) = a/b, then csc(theta) = b/a.

I need some help please. Write a function rule to describe each statement...

hichkok12 [17]

You could see the pattern

it cost 3.8 cent to print 1 dollar,

It cost 2 x 3.8 cents to print 2 dollar

it cost 3 x 3.8 cents to print 3 dollar

First equation
f(x) = 3.8 x

Same with second equation,
f(x) = 15x

for equation 3, it would be :

y = 1.50 x - 0.8x

Hope this helps

In triangle ABC, BC=4 centimeters, m angle B=m angle c, and m angle a = 20 degrees. What is AC to two decimal places?

maks197457 [2]

Answer:

The correct answer AC = 11.52

Step-by-step explanation:

From the figure attached with this answer shows the triangle ABC.

BC=4 centimeters, m angle B=m angle c, and m angle a = 20 degrees

From the figure we can see that D is the mid point and AD⊥BC

Then BD = CD = 4/2 = 2 cm

<BAD = 10° and <CAD = 10°

By using trigonometric ratio,

sin 10 = CD/AC = 2/AC

AC = 2/sin 10 = 2/0.1736 = 11.52

Therefore the value of AC = 11.52 cm
