Answer:
The fund invested by Mr. Boris in B is $ 452.8
Step-by-step explanation:
Given as :
The profit percentage return from fund A = 8 %
The profit percentage return from fund B = 2 %
Let the amount invested in fund B = x
So , The amount invested in fund A = 2x
The total profit earn together = 1440
So, The profit earn from fund A = 2x + 8% of 2x = 2.16 x
And The profit earn from fund B = x + 2% of x = 1.02 x
∴ 1.02x + 2.16x= 1440
Or, 3.18x = 1440
∴ x = = 452.8
So, The fund invested ib B = x =$ 452.8
Hence The fund invested by Mr. Boris in B is $ 452.8 Answer

Answer:
The amount it took in 2011 to equal the value of 1 currency unit in 1917 was of 24.091 currency units.
The amount it took in 2019 to equal the value of 1 currency unit in 1917 was of 28.031 currency units.
Step-by-step explanation:
The value needed to equal the value of 1 currency unit in 1917, in x years after 1990, is given by:
a) Use this function to predict the amount it will take in 2011 and in 2019 to equal the value of 1 currency unit in 1917
2011 is 2011 - 1990 = 21 years after 1990, so we have to find V(21).
The amount it took in 2011 to equal the value of 1 currency unit in 1917 was of 24.091 currency units.
2019 - 1990 = 29, so we also to find V(29).
The amount it took in 2019 to equal the value of 1 currency unit in 1917 was of 28.031 currency units.
