What is the inverse of the function H(x)=3/4x+12
Mrac [35]

Answer:

h^{-1}(x) = \frac{4x-48}{3}

Step-by-step explanation:

let y = h(x) and rearrange making x the subject, that is

y = \frac{3}{4} x + 12 ( multiply through by 4 to clear the fraction )

4y = 3x + 48 ( subtract 48 from both sides )

4y - 48 = 3x ( divide both sides by 3 )

\frac{4y-48}{3} = x

Change y back into terms of x, thus

h^{-1} (x) = \frac{4x-48}{3}

Vlad [161]
At 16 feet we have
16 = 3 + 30t - 16t^2

16t^2 - 30t + 13 = 0

t  = [- -30 +/- sqrt(30^2 - 4*16*13) ] / 32

t  = 1.20 , 0.68 seconds  answer   ( correct to the nearest hundredth)

x^2 = 5 - x

x^2 + x - 5 = 0

-1 +/-\frac{ \sqrt{ {1}^{2} - 4(1 \times  - 5) } }{2}

x = (1 + √21) / 2

x = (1 - √21) / 2

12. The function M(h) = 10e-0.173h can be used to find the number of milligrams M of morphine that is
vodomira [7]

Answer:

Part A; Initial dosage is 10 milligrams

Part B:

8.4113 milligrams after 1 hour

5.0057 milligrams after 4 hours.

Step-by-step explanation:

It is given M(h)= 10 e^{-0.173h}

Initial dosage is the 10 milligrams

After 1 hour, plug in h as 1

So, M(1)=10e^{-0.173*1}

Simplify the right side

M(1)=10(0.84113)

M(1)= 8.4113 milligrams.

Now, after 4 hours

M(4)=10 e^{-0.173*4}

M(4)=10(0.50057)

M(4) =5.0057 milligrams
