Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
A = $235,000
P = $53,000
n = 1 because it was compounded once in a year.
t = 18 years
Therefore,.
235000 = 53000(1 + r/1)^1 × 18
235000/53000 = (1 + r)^18
4.43 = (1 + r)^18
Raising both sides to the power of 1/18, it becomes
4.43^(1/18) = (1 + r)^18 × 1/18
1.086 = 1 + r
r = 1.086 - 1
r = 0.086
r = 0.086 × 100 = 8.6%
Answer:

3. y= tan x is pi/2, 3pi/2
4. y=sin x is (0,0) and (pi/2,1)
5. y= csc x is (-pi/2,-1) and (pi/2,1)
Step-by-step explanation:
Answer:
x > -3
Step-by-step explanation:
16,900,000 in scientific notation is 16.9 times 10^7.
When you move the decimal point to the 1, it goes 7 spaces to the left, so the exponent will be a positive 7.
Answer:
94 dollars
Step-by-step explanation:
3 * 11.75 = 35.25
5 * 11.75 = 58.75
35.25 + 58.75 = $94
Hope it helps!
