Answer:
![r(n)=14,000(0.50)^n](https://tex.z-dn.net/?f=r%28n%29%3D14%2C000%280.50%29%5En)
Step-by-step explanation:
we know that
The equation of a exponential decay function is equal to
![r=a(1-r)^n](https://tex.z-dn.net/?f=r%3Da%281-r%29%5En)
where
r is the number of bacteria remaining
n is the number of hours since the antibiotic was applied
a is the initial value
r is the rate of change
we have
![a=14,000\ bacteria\\r=50\%=50/100=0.50](https://tex.z-dn.net/?f=a%3D14%2C000%5C%20bacteria%5C%5Cr%3D50%5C%25%3D50%2F100%3D0.50)
substitute
![r(n)=14,000(1-0.50)^n](https://tex.z-dn.net/?f=r%28n%29%3D14%2C000%281-0.50%29%5En)
![r(n)=14,000(0.50)^n](https://tex.z-dn.net/?f=r%28n%29%3D14%2C000%280.50%29%5En)
Answer:
3
Step-by-step explanation:
Same sides
Answer:
![5 + 7x = 11 + 7x \\ 7x - 7x = 11 - 5 \\ 0x = 6](https://tex.z-dn.net/?f=5%20%2B%207x%20%3D%2011%20%2B%207x%20%5C%5C%207x%20-%207x%20%3D%2011%20-%205%20%5C%5C%200x%20%3D%206)

Y= # yellow fabric yards
5 1/3= 3 2/3+ y
Convert to improper fractions
((5*3)+1)/3= ((3*3)+2)/3 + y
16/3=11/3+y
Subtract both sides by 11/3
5/3=y
or
1 2/3=# yellow facric yards
Hope this helps! :)
Domain x < or equal to 5
