OleMash [197]

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 → \frac{1}{5}  m L

⇒ 4708 . 2 mg → \frac{1}{5} \times 4708.2  m L

⇒ 4708 . 2 mg → 941. 64 ml

Find the zeroes of the polynomial function f(x)=x^4-5x^3+11x^2-25x+30.
katen-ka-za [31]

Step-by-step explanation:

x⁴ − 5x³ + 11x² − 25x + 30

x⁴ − 5x³ + 6x² + 5x² − 25x + 30

x² (x² − 5x + 6) + 5 (x² − 5x + 6)

(x² + 5) (x² − 5x + 6)

(x² + 5) (x − 2) (x −3)

The zeros are 2, 3, and ±√5i.
