2 x pi radians = 360 degrees, [remember this formula]
2 x 3.14 = 6.28 radians = 360 degrees
therefore 1 radian = 360 degree/ 6.28 or 57.32 degrees approx.
3.5 radians is therefore = 57.32 x 3.5 = 200.62
closest answer would be b ) 200.54 degrees
Answer:
18(2x - 3)
Step-by-step explanation:
Hey there! :)
In order to factor 36x - 54, you must find the common factors of it.
So, we must ask ourselves : what number goes into BOTH 36x & -54?
Our answer is going to be 18.
So, let's ask ourselves a couple more questions :
How many times does 18 go into 36x?
&
How many times does 18 go into -54?
36x ÷ 18 = 2x
-54 ÷ 18 = -3
Therefore, 18 goes into 36x 2 times while 18 goes into -54 3 times.
So now that we know that, simply take 18 out like so :
18(2x - 3)
This is our answer because when multiplied by 2x, 18 turns into 36x. In addition, when multiplied by 18, -3 turns into -54.
Hope I helped! :)
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
4x + 5y = - 45 ( subtract 4x from both sides )
5y = - 4x - 45 ( divide terms by 5 )
y = - 
x - 9 ← in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= 
, then
y = x + c ← is the partial equation
To find c substitute (- 4, - 11 ) into the partial equation
- 11 = - 5 + c ⇒ c = - 11 + 5 = - 6
y = x - 6 → B
