Y=1x because if you draw it on the line you’ll see the linear variation
Answer:
x = 23 degrees
Step-by-step explanation:
sin theta = opposite side/ hypotenuse
sin x= 9/23
Take the arcsin of each side
arcsin( sinx) = arcsin (9/23)
x = arcsin (9/23)
x=23.03568411
Rounding to the nearest degree
x = 23 degrees
Answer:
Amount after one year = $410
Error made = $260
Step-by-step explanation:
Number of quarters in one year = four quarters
Hence amount after one year = P(1+r)⁴
A = 325(1+0.06)⁴ = $410
Error made = 670 - 410 = $260
