Answer: The value of k is 0.09.
Step-by-step explanation:
Since we have given that
Here, k is the rate ,
t is the time,
In 2004, the whooping cranes tallied 213 birds,
So, P(t)=213
It is 19 greater than 2003,
So, P(0)=213-19=194
So, substitute all the values in given expression:
Hence, the value of k is 0.09.
" 1 / 4 " means " 1 divided by 4 ".
Do that division, and you get " 0.25 " .
To change any number to percent, multiply the number by 100 .
The easy way to do that is to move the decimal point 2 places that way ==> .
When you multiply 0.25 by 100, you find that it's <em>25%</em> .
Answer:
Step-by-step explanation:
So we have the function:
To solve for the inverse of a function, change f(x) and x, change the f(x) to f⁻¹(x), and solve for it. Therefore:
Add 9 to both sides:
Take the natural log of both sides:
The right side cancels:
Divide both sides by 6:
And we're done!
Answer:
Very simply divide the 3 months cost, $180, by 3.
180/3 = 60
y = 60x
