Answer:
domain {- 5, 5 }
Step-by-step explanation:
given values in the range, that is values of y then to find the domain equate f(x) to the given values in the range, that is
x + 5 = 0 ⇒ x = - 5
x + 5 = 10 ⇒ x = 10 - 5 = 5
domain is x ∈ { - 5, 5 }
Answer:
-90° = 3π/2 radians
Step-by-step explanation:
Keep in mind that -90° represents a 90° clockwise rotation from the positive x-axis. This is the same as a 360°-90°=270° counter-clockwise rotation from the positive x-axis.
To convert from degrees to radians, we simply multiply the degrees by π/180 radians. So, the answer is (270)(π/180)=(270π/180)=3π/2 radians

I'm pretty sure the answer is B
Step-by-step explanation:
sorry if I'm wrong
Answer:
hope this answer will help u.
Step-by-step explanation:
<em>( 5x + 3y )² - ( 5x - 3y )² - 60xy</em>
<em>= ( 25x² + 30xy + 9y²) - ( 25x² - 30xy + 9y² ) - 60xy</em>
<em>= 25x² + 30xy +9y² - 25x² + 30xy - 9y² - 60xy</em>
<em>= 60xy - 60xy</em>
<em>= 0</em>
