Answer:
(y−3)2=16(x−2) is the equation of the parabola. Explanation: Whenever vertex(h,k) is known to us, we must preferably use the vertex form of the parabola:
Step-by-step explanation:
If $3 was 25% of the original price then 3*4 = $12
Given:
m = -8 degrees/hour, the rate of change of temperature
Let x = hours
Let y = temperature, °F
Then y = -8x + b
where b = constant
When x = 0, then y = b.
Therefore b = initial temperature
If the temperature drops by at least 36 °F in the next x hours, then
b - y(6) ≥ 36
b - (-8x + b) ≥ 36
8x ≥ 36
x ≥ 4.5 hours
Answer: At least 4.5 hours
The equation for this would be:

. first you want to multiply 60 by 220, then divide the product by 165. 60 times 220 is 13,200. Now divide 13,200 by 165. This will give you 80. Todd has to eat 80 grams of protein each day to stay healthy.
