Answer:
$697.09
Step-by-step explanation:
The computation of the investment after 3 years is shown below:
As we know that
Amount = Present value × (1 + rate)^number of years
= $600 × (1 + 0.05 ÷ 365)^365× 3
= $697.09
Hence, the investment after 3 years is $697.09
We simply used the above formula to determine the investment
Answer:
74.8 m
Step-by-step explanation:
We are given that
Speed of peacock,v=10 km/h
Time,t=1 min 12 sec=60+12=72 s=
1 hour=3600 s
Distance=vt=
Using 1 km=1000 m
We know that
Using the formula
Hence, the peacock was at height of 74.8 m on the tree.

Answer:
a) y-intercept is 4000
b)T(18)=5710
Step-by-step explanation:
a) This is the equation of a line with slope 95 and y-intercept 4000.
The y-intercept represents the basic amount the student has to pay even if not taking any unit: $4000
b) T(18) represents the total amount to be paid by a student who is taking 18 units: T(18) = 4000 + 95*18 = 4000 + 1710 = 5710
So a total tuition of $5710
