Answer:
h = √(7.5² - 2.1²) = 7.2 m
Step-by-step explanation:
Answer:
A=10,000(1+.02/12)^4*t
Step-by-step explanation:
First off u need to know how many years to get the answer but for the rest:
P- is principle and is the amount you are starting with, in this case 10,000.
You can either use 1+ or 1- this depends on wheather the amount is increasing or decreasing
Increasing: 1+ ; Decreasing: 1
(The problem already has it for you)
R- is the rate, here you take the percentage and move the decimal twice to the left. In this problem 2% moved to the left is .02.
N- Depends on what the problems says
Quarterly- 4 (cuz it means 4)
Daily- 365 (Number of days in a year)
Weekly- 52 (Number of weeks in a year)
Monthly- 12 (Number of months in a year)
Yearly- 1 ( One year)
Finally you square the number of years by the N.
This is a simple conversion from metres to kilo metres problem in which we should know how much metres is one kilo metre or how much kilo meters is one metres.
So in order to convert from metres to k m we just have to divide by 1000 as 1 km is equal to 1000 meters. Similarly for the other way round we have to multiply by 1000 as 1 metre is 0.001 km.
SO if Mary swims 850 metres each day then she swims around 0.85 km every day.
True because the mode is the number that repeats the most.
