Answer:
Step-by-step explanation:
Solve the square.
Divide both sides by 12.
Answer:
graph C
Step-by-step explanation:
(x+3)(x+1) = 0
therefore x = -3 and x = -1
1. The relationship is proportional.
2. The slope is negative.
3. The equation is y = -3x
Answer:
See verification below
Step-by-step explanation:
We can differentiate P(t) respect to t with usual rules (quotient, exponential, and sum) and rearrange the result. First, note that
Now, differentiate to obtain
To obtain the required form, extract a factor in both the numerator and denominator:
