Cosecant of C = hypotenuse/ opposite side

hypotenuse =√ (-8)² + (-6)² = √100 = 10

Cosecant of C = 10/ -8 = - 5/4

A drug used to relieve anxiety and nervousness has a half-life of 16 hours. if a doctor prescribes one 2.8-milligram every 24 ho
dlinn [17]

After 24 hours, 35.4% of the initial dosage remains on the body.

<h3>What percentage of the last dosage remains?</h3>

The exponential decay is written as:

f(x) = A*e^{-k*x}

Where A is the initial value, in this case 2.8mg.

k is the constant of decay, given by the logarithm of 2 over the half life, in this case, is:

k = ln(2)/16h

Replacing all that in the above formula, and evaluating in x = 24 hours we get:

f(24h) = 2.8mg*e^{-24h*ln(2)/16h} = 0.9899 mg

The percentage of the initial dosage that remains is:

P = \frac{0.9899mg}{2.8mg}*100\% = 35.4\%

A line passes through the point (0, 1) and has a positive slope. Which of these points could that line NOT pass through? Check a
Vinvika [58]

We have to find slopes one by one.

\\ \sf\longmapsto Slope=m=\dfrac{y_2-y_1}{x_2-x_1}

#1

  • (0,1)
  • (12,3)

\\ \sf\longmapsto \dfrac{3-1}{12-0}

\\ \sf\longmapsto \dfrac{2}{12}

\\ \sf\longmapsto \dfrac{1}{6}>0

  • Line passes through this.

#2

  • (-2,-5)

\\ \sf\longmapsto \dfrac{-5-1}{-2-0}

\\ \sf\longmapsto \dfrac{-6}{-2}

\\ \sf\longmapsto 3>0

  • Line passes through this

#3

  • (-3,1)

\\ \sf\longmapsto \dfrac{1-1}{-3-0}

\\ \sf\longmapsto \dfrac{0}{-3}=0

  • Not possible (Line passes through y axis as one co-ordinate is (0,1))

#4

  • ( 1,15)

\\ \sf\longmapsto \dfrac{15-1}{1-0}

\\ \sf\longmapsto \dfrac{14}{1}

\\ \sf\longmapsto 14>0

  • Line passes through this

#5

  • (5,-2)

\\ \sf\longmapsto \dfrac{-2-1}{5-0}

\\ \sf\longmapsto \dfrac{-3}{5}

  • Line doesnot pass through this.
