Answer:

cos Ф = adj / hyp could be either 4/5 or -4/5.

Step-by-step explanation:

If sin Ф = 3/5, then we can assume that the opposite side is 3 and the hypotenuse is 5.  Using the Pythagorean Theorem, we find that the adjacent side is 4:  

√(5² - 3²) = √16 = ±4.

cos Ф = adj / hyp could be either 4/5 or -4/5.

Answer:

\frac{4}{5}

Step-by-step explanation:

Given,

sin \theta = \frac{3}{5}

\because sin \theta =\frac{\text{Opposite side of }\theta}{\text{Hypotenuse }}

By comparing,

Opposite side of \theta = 3

Hypotenuse = 5,

By pythagoras theorem,

Adjacent side of \theta = \sqrt{5^2 - 3^2}=\sqrt{25-9}=\sqrt{16}=4

Now,

cos \theta =\frac{\text{Adjacent side of }\theta}{\text{Hypotenuse }}

\implies cos \theta=\frac{4}{5}

How would you model the function rule Y=-2x-3 with a table of values. can you pretty please show your work i just need help i've
yawa3891 [41]
Y = -2x - 3

First make a table, then start inserting the x's you choose and figure out the y's.

x             y
----------------------
-2       -2(-2) -3
             4 - 3
                 1
-----------------------
-1        -2(-1) - 3
               2 - 3
                 -1
------------------------
0          -2(0) - 3
               0 - 3
                -3
-------------------------
1           -2(1) - 3
               -2 - 3
                 -5
--------------------------
2           -2(2) - 3
               -4 - 3
                  -7
--------------------------

Now you can plot the points into a graph.
(-2, 1), (-1, -1), (0, -3), (1, -5), (2, -7)
