Answer:
Only options A and B are correct, i.e. y = sin∅ and y = cos∅.
Step-by-step explanation:
The graphs that oscillate, should be periodic in nature and continuous functions.
We know all trigonometric functions are periodic in nature. But not all trigonometric functions are continuous.
The function is continuous if its values are defined at all angles and it should not be undefined for any particular angle.
We know the following facts:-
tan(90°) = ∞
sec(90°) = ∞
csc(0°) = ∞
cot(0°) = ∞
<u>Only sin and cos don't have values ∞ at any angle.</u> It means only sin and cos are continuous functions.
Hence, only options A and B are correct, i.e. y = sin∅ and y = cos∅.
Answer:
x=9
adjacent angles
Step-by-step explanation:
we can set up an equation because if we add these angles, we will get our 90 degree angle,
lets solve for x, first add like terms,
9x+9=90, subtract 9 from both sides, 9x+9-9=90-9, 9x=81
divide both sides by 9 and we get 9, so x=9
These are adjacent angles because adjacent angles are angles that are right next to each other. They can form a bigger angle because they are right next to each other
Answer:
2x + 10
= 2(24) + 10
= 48 + 10
= 58
It will take 58 minutes to make and pack an order for 24 parts.

Answer:
13.5
Step-by-step explanation:
6 x^2
Let x= 1.5
6 ( 1.5) ^2
6 *2.25
13.5
