Answer:
The function of f(x) is 20 for the middle problem idk the others
Step-by-step explanation:
A. you plug in to a calculator, which will give 1840.986 so you need to round up to 1840.99. if you truncate it to .98 then he won't reach 2000 in 3 years
b. for this one if you look at the equation given to find the principle it is principle = result (1+rate) ^ -time
if you re arrange this you get result=principle (1+rate)^time
so result = 1840.99(1.028)^5
= 2113.57
Answer:
23.2
Step-by-step explanation:
Scaling down by a factor of 1/10 is equal to dividing the number by 10.
So 232 getting scaled down by a factor of 1/10 is equivalent to 232/10 i.e. 23.2.
