The values for x and y are respectively given as
- x = 50
- y= 90
This is further explained below.
<h3>What is the values for x and y ?</h3>Generally, the equation for secent is mathematically given as
Therefore
80 = 130-x
x = 50
b) To Solve for y Now we find a measure of arc CD
ArcCD = 360-130-50
ArcCD = 180
In conclusion,(1/2) of the arc measure is equal to the angle that is on and inside a circle.
y = 180/2
y= 90

Answer:
Exponential Function:
Balance after
t=1 $ 13,524.32
t=2 $ 14,374.99
t=5 $ 17,261.69
t=10 $ 23,417.64
Step-by-step explanation:
Formula used to find amount in the account after time t, given the interest rate is compounded continuously
where: P= principal amount or amount invested
r= interest rate
t= time
A= amount after time t
in our question we are given:
P=$12,724
r= 6.1% or 0.061
The above equation is exponential function that describes the amount in the account after time t in years
Now, for t = 1
A= $ 13,524.32
t=2
A= $ 14,374.99
t= 5
A= $ 17,261.69
t=10
A= $ 23,417.64
