Answer:
<u> The total amount = $175</u>
Step-by-step explanation:
Let the total amount in his bank account = x
Nick decided to take 2/5 of the money in his bank account and donate it to a local charity
So, he donates with 
If nick donated $70 to a local charity
so, 
solve for x
∴ x = 5*70/2 = 350/2 = $175
<u>So, The total amount = $175</u>
The inverse fraction of 15x+14 is f^-1 (x)= x/15-14/15
The unknown number is 1/2 or 0.5.
ex: 4x+6=8
Answer:
f(5) = 26.672 which is option D
Step-by-step explanation:
From question, f(1) = 2 and f'(x)=√(x^3 + 6)
f(5) = f(1) + (5,1)∫ f'(x) dx
Integrating using the boundary 5 and 1;
f(5) = 2 + (5,1)∫√(x^3 + 6) dx
f(5) = 2 + 24.672
So f(5) = 26.672
