A/3=7/10
21=10a
a=2.1
100a=100*2.1=210
600 ft. This is because you travel 10 feet per second and there are 60 seconds in a minute. 10 x 60 =600
The last one. And I did answer for you too.
The question is:
19. if g(x) = 3 + x + e^x, find the inverse function of g (4).
Solution:
1) Put the equation as y = 3 + x + e^x
2) Solve for x = > x + e^x = y - 3
3) switch x and y => y + e^y = x - 3
4) y is the inverse
5) find y for the value requested (x = 4)
=> y + e^y = 4 - 3
=> y + e^y = 1
the solution is y = 0 because 0 + e^0 = 0 + 1 = 1.
Answer: 0.
