Hope this helped! :3
Solution :
Amount of money Victoria has = $200
The amount modelled by function = h(x) = 200
According to the function,
s(x) = (1.05)x - 1
It means that the total amount of the interest that Victoria will receive s(x) is equal to original amount of $200 which multiplied by the rate of interest (1.05) and then multiplied by the time that Victoria keeps the money in the bank (x) minus 1.
X + 44 is correct
X = AN UNKNOWN
Answer:
9%
Step-by-step explanation:
Given that
The invested amount is $1,000
The future value is $2,400
The time period is 12 years
We need to find out the annual rate that compounded continously
So,
As we know that
Amount = Present value × e^(rate × time)
$2,500 = $1,000 × e^(rate × 12)
2.5 = e^(rate × 12)
ln 2.5 = 10r
ln 2.5 ÷ 10 = r
r = 9%
Answer:
-15.
Step-by-step explanation:
The temperature dropped 3°c every hour.
So, the change in temperature every hour = -3°C.
Total number of hours for which the temperature were changed =5.
Thus, the total change in temperature = change for an hour x total number of hours,
= -3° x 5
= -15°.
