Answer:
5/1
Step-by-step explanation:
Invert the denominator and multiply
10/9 * 9 / 2
The 9s cancel and you are left with
10/2 = 5
So the answer is 5, but the format demands it be a fraction so the answer is 5/1
Answer:
f(x) = 3 cos(x) + 3
Step-by-step explanation:
Answer:
A.0.87
Step-by-step explanation:
correct me if I'm wrong
-2 because if it’s 1/4 and you put it in to the slope formula you do -1-y over 10-6 and then you plug in that -2 to the y and you get 1/4
So y=-2
Using an exponential function, it is found that the decay rate is of 6.24% a year.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
The half-life is of 10.75 years, hence A(10.75) = 0.5A(0) and this is used to find the decay rate r.



![\sqrt[10.75]{(1 - r)^{10.75}} = \sqrt[10.75]{0.5}](https://tex.z-dn.net/?f=%5Csqrt%5B10.75%5D%7B%281%20-%20r%29%5E%7B10.75%7D%7D%20%3D%20%5Csqrt%5B10.75%5D%7B0.5%7D)

1 - r = 0.9376.
r = 1 - 0.9376.
r = 0.0624.
The decay rate is of 6.24% a year.
