Answer:
Step-by-step explanation:
Applying double angle identity:
Doing so would give:
We need to get everything to one side so we have 0 on one side.
Subtract 1 on both sides:
Add on both sides:
Let's factor the left-hand side.
The two terms on the left-hand side have a common factor of .
.
This implies we have:
.
We need to solve both equations.
You are asking they be solved in the interval .
This means look at your unit circle and find when you have your y-coordinates is 0.
You this at 0 and . (I didn't include because you don't have a equal sign at the endpoint of .
Now let's solve
Subtract 1 on both sides:
Divide both sides by 2:
Now we are going to go and look for when the y-coordinates are -1/2.
This happens at and .
The solution set given the restrictions is
Answer:
15.56
Step-by-step explanation:
Total flour available=35 cups
Each cake=2 1/4 cups
Find how many cakes Pauline can bake with 35 cups of flour
Let the number of cakes she can bake with 35 cups of flour=x
x=35 cups / 2 1/4 cups
=35÷9/4
=35×4/9
=140/9
=15 5/9 cakes
=15.56 cakes approximately
Answer:
Second choice.
Step-by-step explanation:
Set the compass to the radius of the circle because the sides of the hexagon are equal to the radius.
Answer:
I would say the Pennington line is steeper because the slope of the purple line is 2 and the other is 3/2 (don't know if they want slope or not) and it represents that it took 2.5 to three hours to travel 240 miles compared to the other one that takes four hours to travel the same distance. Hopefully that's right
