Answer:

y≤\frac{1}{3} x+1

Step-by-step explanation:

Since the graph is facing down, We know the equation is y<mx+b

Since slope is rise/run the slope is 1/3.

Since the y intercept (The point where the line hits y) is 1, the equation is

y<1/3x+1

BUT WAIT!

The line is solid meaning that we have to include the line as part of the values. This will make the new equation

y≤\frac{1}{3} x+1

Please help with these questions.

1. OK, we want csc A, which is 1/sin A.  When we have a right triangle whose hypotenuse is the square root of two times the side, we're where the Pythagoreans were twenty five hundred years ago when they realized the diagonal of the unit square was incommensurate with the side.

In other words we have an isoceles right triangle, 45 degree angles, a=b=14 and c=14 \sqrt{2}.  So \sin A = 1/\sqrt{2} so \csc A=\sqrt{2}, fourth choice.

2. AC adjacent to 23, C is a right angle because 23+67=90.  We have hypotenuse AB, so 

\cos A = \dfrac{AC}{AB} \quad \textrm{or} \quad AC=AB \cos A = 7.8 \cos 23, choice four.

3.  The cosine is adjacent over hypotenuse.

\cos A = 36/60 = 3/5

The sine is opposite over hypotenuse,

\sin B= 36/60 = 3/5

First choice

Simplify (3v5+8v3−10v2)−(−12v5+4v3+14v2) . Write answer in standard form.<br> ​<br> ​
Tatiana [17]

Answer:

15v^5+4v^3-24v^2

Step-by-step explanation:

Distribute the Negative Sign:

=3v5+8v3−10v2+−1(−12v5+4v3+14v2)

=3v5+8v3+−10v2+−1(−12v5)+−1(4v3)+−1(14v2)

=3v5+8v3+−10v2+12v5+−4v3+−14v2

Combine Like Terms:

=3v5+8v3+−10v2+12v5+−4v3+−14v2

=(3v5+12v5)+(8v3+−4v3)+(−10v2+−14v2)

=15v5+4v3+−24v2

Answer:

=15v5+4v3−24v2

Hope this helps! :)
