Answer:
22 AUD × (1 USD)/(1.2 AUD)
Step-by-step explanation:
1.2 AUD = 1 USD
Divide both sides by 1.2 AUD.
(1.2 AUD)/(1.2 AUD) = (1 USD)/(1.2 AUD)
(1 USD)/(1.2 AUD) = 1
The conversion factor from AUD to USD is (1 USD)/(1.2 AUD)
Answer: 22 AUD × (1 USD)/(1.2 AUD)
Answer:
-0.25268 rad + 2πn , 3.394273 rad + 2πn
≈ - π /12 + 2πn, π + 2πn
Step-by-step explanation:
sin( x ) = -0.25
x = sin^-1 ( -25 )
The solutions of the equation sin( x ) = -0.25 are :
X = -0.25268rad + 2πn , 3.394273rad + 2πn
≈ - π /12 + 2πn, π + 2πn
Answer:
The last one which you was on is correct.
Answer:
1
Step-by-step explanation:
Answer:
2 and -2
Step-by-step explanation:
● 7q^2 -28 = 0
Add 28 to both sides
● 7q^2-28+28 = 28
● 7q^2 = 28
Divide both sides by 7
●7q^2/7 = 28/7
● q^2 = 4
You can write directly q= 2 or q= -2
To understand it use the absolute value.
● |q| = 2
● q = 2 or q = -2
The solutions are {2, -2}
