The first two are correct
Answer:
It will be 0.5kg cuz kg and liters are same
<u>Answer and explanation</u>
(1+sinθ)(1-sinθ)=cos²θ
We are to prove that the left hand side is equal to the right hand side.
(1+sinθ)(1-sinθ) = 1(1-sinθ) + sinθ(1-sinθ)
= 1 - sinθ + sinθ - sin²θ
= 1 - sin²θ
From the trigonometric identity sin²θ + cos²θ = 1,
1 - sin²θ = cos²θ
Answer:
Option B, Shows change over time
Step-by-step explanation:
Since the slope of a line graph could be found out by the formula;
Change y / Change in x...
<u>This represents change over time</u>
Hope this helps!
