Explanation:
Since sin
θ
is negative, it can be in the third or fourth quadrant
Drawing your right-angled triangle, place your
θ
in one of three corners. Your longest side will be 3 and the side opposite the
θ
will be -2. Finally, using Pythagoras theorem, your last side should be
√
5
Now, if your triangle was in the third quadrant, you would have
cos
θ
=
√
5
−
3
since cosine is negative in the third quadrant
But if your triangle was in the fourth quadrant, you would have
cos
θ
=
√
5
3
since cosine is positive in the fourth quadrant
Answer: 150
Step-by-step explanation:
30% = 0.3
100-30=70
70% = 0.7
0.7 X 500 = 350
500-350 = 150
The slope is the number with the letter x
The slope would be -10
The y intercept is the number at the end of the equation.
The y intercept is 1
Answer:
−3m + 3
Step-by-step explanation:
The equation that represents the linear function is y =32x
<h3>What is a linear function?</h3>
The question is an illustration of a linear function; a linear function is a function that has a constant rate/slope
A linear function is represented as:
Where
- m represents slope
- c represents the y-intercept
The slope is calculated as:
So, we have:
The linear equation is then calculated as:
So, we have:
Hence, the equation that represents the linear function is y =32x
