Answer:
$115 each
Step-by-step explanation:
(800 - 340)/4 = 115
Answer:
C
Step-by-step explanation:
(2x+3)(x+4) = 2x² + 8x + 3x + 12
= 2x² + 11x + 12 ≠ 2x² + 10x + 12
Using derivatives, the rate of change of the mineral level with respect to time for 4 days is -0.012 mg/cm².
<h3>What is the missing information?</h3>
The function for the amount is missing, and is given by:

The problems asks for the rate of change of the mineral level with respect to time for 4 days.
<h3>What is the rate of change after 4 days?</h3>
The rate of change after 4 days is given by:
C'(4).
Applying the chain rule, the derivative of C(t) is given as follows:


When t = 4, we have that:


Applying properties of exponents, we have that:

Hence:

C'(4) = -0.012.
The rate of change of the mineral level with respect to time for 4 days is -0.012 mg/cm².

The equation

tells us that the slope is 5/9. By definition, this means that if you increase F by one, C will increase by 5/9.
Inversely, the slope would become 9/5=1.8. This means that if you increase C by one, F will increase by 1.8.
You add 11y to 11y and 12x to 12x. then you have 17=22y+ 24x=14
-14 -14
14 cancels out. 3=22y+24x
