Solution:
Weight of person = 179 lbs
As given person needs IV Drip in m L.
Also,→ 10 mg = 2 m L
Now, you must remember , → 1 lbs = 0.453 Kg (approx)
→179 lbs = 179 × 0.453 Kg = 78.47 Kg (approx)
The person needs at least 60 mg for each Kg they weigh.
⇒ 1 Kg → 60 mg
⇒ 78.47 × 1 Kg → 78.47 × 60 mg
⇒ 78.47 Kg → 4708.2 mg
Also, 10 mg → 2 m L
⇒ 1 mg → m L
⇒ 4708 . 2 mg → m L
⇒ 4708 . 2 mg → 941. 64 ml
To get the graph to have one x-intercept, we must find the m value where the discriminant of the equation will equal 0.
The discriminant for a graph with one x-intercept is found with the following formula:
Plug in the values of the equation into this formula:
Add 144 to both sides:
Square root both sides to get m by itself:
In order for the graph to have one x-intercept, m must equal -12 or 12.
