Answer:
- sin(x) = ±(√2)/2
- r.a. = 45°
- x = 45° +k·360°
- x = 135° +k·360°
- x = 225° +k·360°
- x = 315° +k·360°
- x ∈ {135°, 225°, 315°, 405°}
Step-by-step explanation:
Start by solving for sin(x).
4sin(x)² = 2
sin(x)² = 1/2 . . . . divide by 4
sin(x) = ±√(1/2) = ±(√2)/2
Use your knowledge of the sine function to recognize that the reference angle is 45°, and that the angles x will be ...
x = ±45° or 180°±45° with multiples of 360° added
The solutions in the desired range are ...
x ∈ {135°, 225°, 315°, 405°}
Answer:
TRUE TRUE FALSE TRUE FALSE TRUE TRUE TRUE
Step-by-step explanation:
$6,000 because if $1,200 is 20% of total sales than total sales must be 5 times $1,200
Answer: There is 225 millimeters of slushy originally in the cup.
Explanation:
Since we have given that
Rate at which she drink the slushy = 4.5 millimeters
Time taken to drink the slushy by Mariana = 17 seconds
Total quantity she drank is given by

Still there is left some slushy,
Quantity of slushy left =148.5 millimeters
Total quantity of slushy originally in the cup was given by

Hence, there is 225 millimeters of slushy originally in the cup.
A number that can only be divided by 1 or 0 is prime. A composite number is a number that can be divided by 0, 1, 2, etc. I couldn't really get the question that you were trying to type, but this is what I came up with.
Hope this helps and just remember you are loved!
