What is the point slope equation of the line with slope -12 that goes through the points (5, 3)?
Amanda [17]
The point-slope form of ay line is:

y-y1=m(x-x1), where m=slope and (x1,y1) is any point on the line.

In this case we are given that m=-12 and (x1,y1) is (5,3) so

y-3=-12(x-5)

3. A prescription for an ointment has 3.5 mL of liquid menthol in a total of 220 mL. Calculate the percentage (v/v) of liquid me
Marina CMI [18]

Answer:

The percentage (V/V) of liquid menthol in the ointment is 1.59%.    

Step-by-step explanation:

Given : A prescription for an ointment has 3.5 mL of liquid menthol in a total of 220 mL.

To find : Calculate the percentage (V/V) of liquid menthol in the ointment ?

Solution :

Volume of liquid menthol is V_m= 3.5\ mL

Total volume of ointment is V_t= 220\ mL

The V/V percentage is given by,

\frac{V}{V}\%=\frac{V_m}{V_t}\times 100

\frac{V}{V}\%=\frac{3.5}{220}\times 100

\frac{V}{V}\%=0.0159\times 100

\frac{V}{V}\%=1.59\%

Therefore, the percentage (V/V) of liquid menthol in the ointment is 1.59%.

Help please. (right now i’m just filling in for the 20 characters it’s not relevant to the question)
suter [353]

Answer:

9

Step-by-step explanation:

We're using the Pythagorean theorem here since it's a right triangle.

a^2 (side) + b^2 (side) = c^2 (hypotenuse)

12 = a

x = b

15 = c

12^2 + b^2 = 15^2

144 + b^2 = 225

- 144             - 144 (subtracting 144 from both sides to isolate b)

b^2 = 81

\sqrt{b^2} = \sqrt{81} (getting rid of the exponent by squaring both sides)

b = 9

x = 9
