Answer:
θ∈{}
Explanation:
The given equation is
Applying values on 'n' we obtain values of θ that beling to [0,2π)
For n=0, θ=
For n=1, θ =
For n=2,θ =
For n=3,θ =
Answer:
X= 0.673593 if your "x_2" is really x^2.
Step-by-step explanation:
Answer:
14. 28 inches
15. 6.3 cm
16. 1/2 yard
Step-by-step explanation:
14. use the pythagorean theorem for this problem
a^2 + 45^2 = 53^2
you get a^2+2025=2809
subtract 2025 from both sides to get
a^2=784
square root both sides to get 28
15. same thing as question 14
1.6^2+b^2=6.5^2
2.56+b^2=42.25
subtract 2.56 from both sides
b^2=39.69
square root both sides to get your answer
b = 6.3cm
16. again use the pythagorean theorem
.3^2+.4^2=c^2
.09+.16=c^2
.25 = c^2
square root both sides to get
c = .5
or
c = 1/2 yard
Bro- basically so the first option a- right? So a is 4-8-12-16. And B is just that times two so the third option down
