What is 4 to the 6th power over 4 to the 8th power?

4⁶ / 4⁸

Since the 'bases' are the same on top and bottom, you can
just subtract the bottom exponent from the top one.

4⁶ / 4⁸
= 4⁶⁻⁸
= 4⁻²
= 1/4²
= 1/16

A 3mL unit dose of levalbuterol HCl contains 0.63mg of active ingredient. If 2 unit doses are used, how many mg of active ingred

Sergio039 [100]

Answer: 0.42 mg

Step-by-step explanation:

Given : A 3mL unit dose of levalbuterol HCl contains 0.63mg of active ingredient.

Then , the amount of active ingredient in 1 ml dose of levalbuterol HCl = $\dfrac{0.63}{3}$

$=\dfrac{63}{300}=\dfrac{21}{100}=0.21\ mg$

Hence, the amount of active ingredient in 2 ml dose of levalbuterol HCl will be :-

$2\times0.21=0.42\ mg$

Hence, the amount of active ingredient in 2 ml dose of levalbuterol HCl =0.42 mg

H(y)=-3y^2+5<br> p(y)=y^3-7y<br> Find (h-p)(y)

gladu [14]

$(h-p))(y) = -y^3-3y^2+7y+5$

Step-by-step explanation:

Given

$h(y) = -3y^2+5\\p(y) = y^3-7y$

We have to find the difference of two functions given

So,

$(h-p)(y) = h(y) - p(y)\\= (-3y^2+5)-(y^3-7y)\\=-3y^2+5-y^3+7y\\=-y^3-3y^2+7y+5$

Hence,

$(h-p))(y) = -y^3-3y^2+7y+5$
