7,,,,,,,,,,,,,,,,,,,,please help

Goryan [66]

Answer:

Step-by-step explanation:

The given expression is

$\frac{2^{\frac{11}{2} }\times 2^{-7}\times 2^{-5}}{2^3\times 2^{\frac{1}{2} }\times 2^{-10}}$

Recall and use

$a^m\times a^n=a^{m+n}$

$\frac{2^{\frac{11}{2} -7-5}}{ 2^{3+\frac{1}{2} -10}}$

$\frac{2^{-\frac{13}{2}}}{ 2^{-\frac{13}{2}}}$

Same bases are dividing, so we write one base and subtract the exponent.

$2^{-\frac{13}{2}+\frac{13}{2}}$

$2^0=1$

Nitella [24]

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
