Answer:
a = 3
Step-by-step explanation:
Factorise both expressions\x² - x - 6 = (x - 3)(x + 2)
x² + 3x - 18 = (x - 3)(x + 6)
Thus both expressions have a common factor of (x - 3) , thus
a = 3
Answer:
360 mg.
Step-by-step explanation:
The medicine has a decay rate of 40% in 25 hours, which means after 24 hours its amount will be 100% - 40% = 60% it's original value.
Let us call
the number of hours passed and
the number of 24-hours passed, then we know that
.
Now, the amount
of medicine left after time
(<em>d</em>th 24-hour) will be
![c = 1000(0.6)^d](https://tex.z-dn.net/?f=c%20%3D%201000%280.6%29%5Ed)
and since
, we have
![$\boxed{c = 1000(0.6)^{\frac{t}{24} }}$](https://tex.z-dn.net/?f=%24%5Cboxed%7Bc%20%3D%201000%280.6%29%5E%7B%5Cfrac%7Bt%7D%7B24%7D%20%7D%7D%24)
We now use this equation to find the final amount after
:
![c = 1000(0.6)^{\frac{48}{24} }](https://tex.z-dn.net/?f=c%20%3D%201000%280.6%29%5E%7B%5Cfrac%7B48%7D%7B24%7D%20%7D)
![c = 1000(0.6)^2 }](https://tex.z-dn.net/?f=c%20%3D%201000%280.6%29%5E2%20%7D)
![\boxed{c =360mg}](https://tex.z-dn.net/?f=%5Cboxed%7Bc%20%3D360mg%7D)

<h2>Explanation: </h2>
The term with the greatest exponent determines the degree of the polynomial.
Let's list all the terms:
Out of all of these terms, the first one has the greatest exponent (5).
