Answer:
f-1(x) = (x - 1)/ 5.
Step-by-step explanation:
Lete f(x) = y = 5x + 1
Now we find an expression for x in terms of y:
y = 5x + 1
5x = y - 1
x = (y - 1) / 5
So the inverse of th function = f-1(x) = (x - 1)/ 5 (answer).
Answer:
t = 13.1576 years
Step-by-step explanation:
The situation can be modeled as
P = Po.(1-r)^t
Where
t is the years transcurred
Po is the initial amount
r is the rate of change
Po = 40000
r = 10% equivalent to 0.1
Now
A quarter of the original amount
(1/4)*Po = Po.(1-r)^t
(1/4) = (0.9)^t
t = 13.1576

Answer:
equilateral
Step-by-step explanation:
Answer:
To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. ...
To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
To find the y-intercept, set x = 0 \displaystyle x=0 x=0.
