Answer:
Yes, the doctor's order within the desired range
Step-by-step explanation:
Given:
Dosage of Rocephin ordered = 200 mg
Mass of the infant = 15.4 lb
1 lb = 0.453592 kg
thus,
15.4 lb = 0.453 × 15.4 = 6.97 kg
Dosage is provided every 8 hours
thus,
Number of dosage per day = 
= 3
Hence,
the total dosage ordered per day = 200 × 3 = 600 mg
Dosage ordered per kg of infant per day = 
or
Dosage ordered per kg of infant per day = 86.083 mg/kg per day
Yes, the doctor's order within the desired range
Yes you are correct. You take half of the x coefficient 18 to get 9, then you square 9 to get 81
x^2+18x+81 is a perfect square trinomial which factors to (x+9)^2
Answer:
√33 cm
Step-by-step explanation:
We know that this is a right triangle, which means that we can apply the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:
a² + b² = c²
Here, a = 4 and c = 7, so plug thes in to find b:
a² + b² = c²
4² + b² = 7²
b² = 49 - 16 = 33
b = √33
The answer is thus √33 cm.
(×-1)(×-3)(×+2)
×=1
×=3
×=-2
×1=-2
×2=1
×3=3
If youre writing an exprssion all you need to do is make variables and multiply by the given number A, C, and S will be our variables.
2A + 3C + 1S = Total cost for andrews family
4A + 2C = Total cost for Spencers family
Now, Does 2A + 3C + 1S = 4A + 2C
lets say A = 5 , C = 3 , and S = 2
2(5) + 3(3) + 1(2) = 4(5) + 2(3)
10 + 9 + 2 = 20 + 6
21 = 26
if this is your example then No, the spencers family spent more than the andrews family, youll have to do the math differently and may come up with a different answer if you were given values that you didn't give us, but this is how its done :)
Hope this helps!
