For this case we have that by definition, it is called arcsine (arcsin) from a number to the angle that has that number as its sine.
We must find the . Then, we look for the angle whose sine is
.
We have to, by definition:
So, we have to:
Answer:
Option B
Answer:
$9450
Step-by-step explanation:
We will use compound interest formula:
Where
F is future amount [what we want to figure out]
P is present amount [9000]
r is rate of interest [since we want for 6 months, the annual interest divided by 2 is r. So r = 10/2 = 5% or 0.05]
t is the time [ the time period is for 6 months so t = 1 since we already converted the interest rate to 6 month chunk]
Putting in formula, we get:
Step-by-step explanation:
pen=1.35 + pencil......1
5pen+8pencil=13.5 calculate this for pen
pen=13.5-8pencil/5.....2 combine equation 1$2
