If θ is in Quadrant III and sinθ = -3/5, then cosθ = _____.

Mathematics

Nikolay [14]3 years ago

Because the angle omega is in QIII, the adjacent side lies to the left of the origin and thus is represented by a negative value.  Since sin omega = -3/5, the opposite side is also negative.  Use the Pythagorean Theorem to obtain the length of the adjacent side:  5^2 = (-3)^2 + x^2, or 25 = 9 + x^2, or x^2 = 16.

Solving for x:  x = plus or minus 4.  Since we are in QIII, let x = -4.

Then cos omega is  opp / hyp, or -4/5.

Answer:

1 : 64

Step-by-step explanation:

Model:

1/2 in * 1/6 in = 1/12 in^2

Real:

1/3 ft * 1/9 ft = 1/3 * 12 in * 1/9 * 12 in = 16/3 in^2

model : real

1/12 / 16/3 = 1/12 * 3/16 = 3/192 = 1/64

model : real = 1 : 64

GenaCL600 [577]
To solve this problem you must apply the proccedure shown below:

 1- You must rewrite each value shown in the picture attached, in decimal form, as following:

 6π-6=12.84
 π^3=31
 √99=9.94

 2- Now, you can order the values from least to greatest:

 √99
 6π-6
 π^3

 The answer is:

 √99
 6π-6
 π^3

A biased dice was rolled and the scores recorded in the table below
dusya [7]

Given:

The table of score and frequency.

To find:

The probability that on the next roll the score will be 4.

Solution:

From the given table it is clear that the score 4 occurs 10 times.

Number of times the dice was rolled = 17 + 24 + 23 + 10 + 16 + 30

                                                             = 120

The probability that on the next roll the score will be 4 is

\text{Required probability}=\dfrac{\text{Number of times 4 occurs}}{\text{Number of times the dice was rolled}}

\text{Required probability}=\dfrac{10}{120}

\text{Required probability}=\dfrac{1}{12}

Therefore, the required probability is \dfrac{1}{12}.
