Answer:
The multiplicative rate of change is 0.5.
Step-by-step explanation:
The given function is
.... (1)
It is given that the curve is passing through (0,10), (1,5) and (2,2.5).
The exponential function is defined as
.... (2)
Where, a is initial value and b is growth factor of multiplicative rate of change.
On comparing (1) and (2), we get
Therefore the multiplicative rate of change is 0.5.
Answer:
Step-by-step explanation:
Part A:
The given values in form of ordered pairs are:
(2,1), (3,1), (4,-3), (3,-3)
A relation can be a function if one value of x is paired with exactly one value of y. In this case, x value of 3 is paired with two y values 1 and -3. So this relation is not a function.
Part B:
f(h) = 15h + 5
f(8) can be found by substituting h=8 in above equation.
So,
f(8) = 15(8) + 5 = 125
h represents the number of hours and f(h) represents the earnings of Kylie. So f(8) shows that Kylie earned $125 from 8 hours of work in the cafe
Part C:
For r hours of work, we can write:
f(r) = 15r + 5
So, the ordered pair can represent this relation as:
(r, f(r))
or
(r, 15r+5)
The answer would be 23i.
Simplify ( 26 + 16i - 26 + 7i )
Gather like terms ( 26 - 26 ) + (16i + 7i)
Simplify (23i)
