Answer:
Step-by-step explanation:
Given
The position of badwater is negated because it is below sea level
The interpretation of the question, is to calculate the distance between the two given points.
This is calculated as:
Open bracket
<em>Hence, the distance between both is 11325ft</em>
To get the common denominator you would multiply the first term by (x-4)/(x-4) and you multiply the second term by (x+4)/(x+4):
<span> (x-4) 4 </span> + <span> x (x+4)</span>
(x-4)(x+4). (x-4)(x+4)
The next step is to distribute the 4 (x-4) and the x (x+4)
so now you have
4x-16 + x^2 + 4x
(x - 4) (x + 4)
now combine like terms and put them in order exponents
<span>x^2 + 8x - 16
</span>(x-4)(x+4)
Since x^2 + 8x - 16 is not factorable you are done. That is your answer:
<span><u>x^2 + 8x - 16</u>
</span>(x-4)(x+4)
You would replace the t with 5 because t = days
1.5(5) + 20 = 7.5 + 20 = 27.5
<span>(-1,2), (3,-2), (0,1), (3,5) - third option
because f(3) is not unique.
Hope it helps!
