Answer:
e
Step-by-step explanation:
The LCM of 15 and 25 is 75
The LCM is the smallest number that you can get from multiplying both numbers.
multiples of 15: 15, 30, 45, 60, 75...
multiples of 25: 25, 50, 75....
as you can see, 75 is the first number to pop up in both.
Hope this helps! ;D
Answer:
(a) After t years, the height is
18t² + 3t + 10
(b) The shrubs are847 cm tall when they are sold.
Step-by-step explanation:
Given growth rate
dh/dt = 1.8t + 3
dh = (18t + 3)dt
Integrating this, we have
h = 18t² + 3t + C
When t = 0, h = 10cm
Then
10 = C
So
(a) h = 18t² + 3t + 10
(b) Because they are sold after every 9 years, then at t = 9
h = 18(9)² + 3(9) + 10
= 810 + 27 + 10
= 847 cm
Given:
principal: 5,500
term: 4 years
interest rate: 4.8% per annum
early wdl of 475
penalty is the 3 months interest of the amount withdrawn.
Interest = 475 * 4.8% * 3/12
Interest = 475 * 1.2%
interest = 5.7 is the amount of the penalty
I'd prefer 5/7 because both numbers would be in decimals and you dont need decimals
