<span>If two terms in a binomial are perfect squares separated by subtraction, then you canfactor them. To factor the difference of two perfect squares, remember this rule: if subtraction separates two squared terms, then the sum and the difference of the twosquare roots factor the binomial.</span>

Answer:
a. 24.9476 Kg.
b. The safe daily dosage range is between 2494760 units /day and 6236900 units/day
c. Yes
Step-by-step explanation:
a. Lets see the convertion from lb to Kg:
- 1 Lb= 0.453592
- 55 lb = 0.453592*55= 24.9476 kg
b. Minimum daily dosage is 100,000 units /kg
- For this kid: 100,000 * 24.9476= 2,494,760 units/ day
- in 6 dosis; 2494760/6= 415,793.33 units every 4 hours
Maximun daily dosage is 250,000 units /kg
- For this kid: 250,000 * 24.9476= 6,236,900 units/ day
- in 6 dosis; 6,236,900/6= 1,039,483.33 units every 4 hours
c: Yes, because 525.000 units every 4 hours is between the minimun and maximun dosaje for this kid
<h3>Answer:</h3>
y = -3(x -2)² -5
<h3>Explanation:</h3>
The equation of a parabola with vertex (h, k) is given by ...
... y = a(x -h)² +k . . . . . . . for some vertical scale factor "a".
We can find the value of "a" by substituting the coordinates of a point that is not the vertex. Here, that point is the y-intercept: (0, -17).
... y = a(x -2)² -5 . . . . . initial form of the equation for the parabola
... -17 = a(-2)² -5 . . . . . substitute y-intercept values
... -12 = 4a . . . . . . . . . . add 5, simplify
... -12/4 = a = -3
The desired equation is ... y = -3(x -2)² -5.
For perpendicular lines, m1m2 = -1 or m2 = -1/m1.
Line y = 2x + 2 has a slope of 2, hence required slope is -1/2
Required equation is y - y1 = -1/2(x - x1)
y - 3 = -1/2(x - 6)
y - 3 = -1/2x + 3
y = -1/2 x + 3 + 3
y = -1/2 x + 6
