Answer:
2nd option
Step-by-step explanation:
To convert from (x, y ) → (r, θ )
where
r =
θ = ( )
Here (x, y ) = (- 4, 5 ), a point in the 2nd quadrant
r = = =
θ = ( ) ≈ 51.3° ← related acute angle , then
θ = 180° - 51.3° = 128.7°
Thus
(- 4, 5 ) → (, 128.7° ) in polar form
Answer:
y = 3/5x - 1
Step-by-step explanation:
The slope found from counting the units is 3/5, and the y-intercept is -1, hence 3/5x - 1
Its actually horizontal reflection, I know cause I got 100% so its right.
The function is decaying.
<u>Step-by-step explanation:</u>
Given:
The above equation can also write as below,
Now from the function we can see that as we are increasing the value of x the value of function is decreasing. Let take some values of x and then find out the value of function at those value of x
When x = 1
,
When x = 2,
When x = 3,
So, from the above examples, we can see that the value of function is decreasing on increasing the value of x. Hence the function is decay
