Krypton-91 is a radioactive substance that decays very quickly. The function Q(t)=Qoe^-kt models radioactive decay of krypton-91. Q represents the quantity remaining after t seconds and the decay constant k is approximately 0.07. How long will it take a quantity of krypton-91 to decay t o10% of its origional amount? round your answer to the nearest second.

Answer:

32.894 seconds ≈ 33 seconds

Step-by-step explanation:

Function : Q(t)=Q_0 e^{-kt}

The function models radioactive decay of krypton-91.

The decay constant k is approximately 0.07.

Q_0 denotes initial amount .

We are require to find How long will it take a quantity of krypton-91 to decay to 10% of its original amount

\Rightarrow 10\%\times Q_0

\Rightarrow 0.10\times Q_0

So, we neet to find t at which Q(t)=0.10 Q_0

0.10 Q_0=Q_0 e^{-0.07t}

0.10 =e^{-0.07t}

Taking log both sides

\log0.10 =-0.07t \log e

\log0.10 = -0.07t \times 0.434294481903

-1 = -0.0304006137332t

\frac{-1}{-0.0304006137332} = t

32.894= t

Thus it will take 32.894 seconds ≈ 33 seconds a quantity of krypton-91 to decay to 10% of its original amount.

What does the law of supply state? When the price is higher, the quantity supplied is lower. When the price is higher, the quantity supplied is higher. When the price is lower, the quantity supplied is higher.

Answer:

When the price is higher, the quantity supplied is higher is the correct answer.

Step-by-step explanation:

law of supply state that When the price is higher, the quantity supplied is higher.

which means that a rise in cost results in the rise in the quantity supply.

when the cost paid by consumers for good increases, then the suppliers raise the quantity of the good in a market.

Thus the law of supply says that If the price is higher it will result in a higher supply of quantity.

QUESTION POSTED AT 28/03/2020 - 10:24 AM

In ΔABC shown below, point A is at (0, 0), point B is at (x2, 0), point C is at (x1, y1), point D is at x sub 1 over 2, y sub 1 over 2, and point E is at the quantity of x sub 1 plus x sub 2 over 2, y sub 1 over 2: How do I prove that segment DE is parallel to segment AB?

Answer with Step-by-step explanation:

We are given that a triangle ABC. In triangle ABC , the coordinates of A is at (0,0), Point B is at (x^2,0), Point C is at (x_1,y_1), Point D is at  (\frac{x-1}{2},\frac{y-1}{2}), Point E is at (\frac{x-1\frac{x-2}{2},\frac{y-1}{2}).

The coordinates of point E can be write as (\frac{3x-4}{2}.\frac{y-1}{2}).

Slope formula of a line passing through two points (x_1,y_1) and (x_2,y_2)is given by

=\frac{y_2-y_1}{x_2-x_1}.

By using slope formula of a line

Slope of line AB which passing through the points A (0,0) and B(x^2,0)

Where x_1=0,x_2=x^2,y_1=0,y_2=0

=\frac{0-0}{x^2-0}

Slope of line AB which passing through the points A(0,0) and B(x^2,0),m_1=0

Slope of line DE which passing through the points D(\frac{x-1}{2},\frac{y-1}{2}) and E(\frac{3x-4}{2},\frac{y-1}{2})

Where x_1=\frac{x-1}{2},x_2=\frac{3x-4}{2},y_1=\frac{y-1}{2}, y_2=\frac{y-1}{2}

=\frac{\frac{y-1}{2}-\frac{y-1}{2}}{\frac{3x-4}{2}-\frac{x-1}{2}}

Slope of line DE,m_2=\frac{\frac{y-1-y+1}{2}}{\frac{3x-4-x+1}{2}}

Slope of line DE,m_2=\frac{0}{\frac{2x-3}{2}}

Slope of line DE which passing through the points D(\frac{x-1}{2},\frac{y-1}{2}), and E(\frac{3x-4}{2},\frac{y-1}{2})

=0

We know that when two lines are parallel then thier slopes are equal.

m_1=m_2

Slope of line DE = Slope of line AB

Hence, the line DE and line AB are parallel lines.

A spinner has four sections lettered A, B, C, and D. The table shows the results of several spins. Find the experimental probability of spinning each letter as a fraction in simplest form, a decimal, and a percent.

Answer: Probability of getting A is given by \dfrac{7}{20}=0.35=35%

Probability of getting B is given by \dfrac{7}{40}=0.175=17.5%

Probability of getting C is given by \dfrac{11}{40}=0.275=27.5%

Probability of getting D is given by \dfrac{8}{40}=\dfrac{1}{5}=0.2=20%

Step-by-step explanation:

Since we have given that

Number of possible outcomes of getting A = 14

Number of possible outcomes of getting B = 7

Number of possible outcomes of getting C = 11

Number of possible outcomes of getting D = 8

Total number of possible outcomes would be

14+7+11+8

=40

So, Probability of getting A is given by \dfrac{14}{40}=\dfrac{7}{20}=0.35=35%

Probability of getting B is given by \dfrac{7}{40}=0.175=17.5%

Probability of getting C is given by \dfrac{11}{40}=0.275=27.5%

Probability of getting D is given by \dfrac{8}{40}=\dfrac{1}{5}=0.5=20%

A quantity a varies inversely as a quantity b, if, when b changes, a changes in the inverse ratio. What happens to the quantity a if the quantity b doubles?

Answer:

if the quantity b doubles, then a becomes half

Step-by-step explanation:

A quantity a varies inversely as a quantity b.

a \propto \frac{1}{b}

a = \frac{k}{b} where, k is constant

When b changes, a changes in the inverse ratio i.e,

  • When b increases, a decrease.
  • When b decreases, a increase.

We have to find what happens to the quantity a if the quantity b doubles.

If the quantity b doubles.

then;

a = \frac{k}{2b}

⇒the quantity a become half

If Gerry is approved for a $150,000 mortgage at 3.75 percent interest for a 30-year loan, what would the monthly payment be? $632.58 $649.67 $682.91 $699.03

Answer:

Option 4 - $699.03

Step-by-step explanation:

Given : If Gerry is approved for a $150,000 mortgage at 3.75 percent interest for a 30-year loan

To find : What would the monthly payment be?

Solution :

Formula of monthly payment  

M=\frac{\text{Amount}}{\text{Discount factor}}  

Discount factor D=\frac{1-(1+i)^{-n}}{i}  

Where, Amount = $150,000

Rate r= 3.75%=0.0375  

i=\frac{0.0375}{12}=0.003125  

Time = 30 years  

n=30\times 12=360  

Now, put all the values we get,    

D=\frac{1-(1+i)^{-n}}{i}  

D=\frac{1-(1+0.003125)^{-360}}{0.003125}  

D=\frac{1-(1.003125)^{-360}}{0.003125}  

D=\frac{1-0.3252}{0.003125}  

D=\frac{0.6747}{0.003125}  

D=215.928  

Monthly payment, M=\frac{\text{Amount}}{\text{Discount factor}}  

M=\frac{150000}{215.928}  

M=694.673  

Approximately, The monthly payment is $699.03

Therefore, Option 4 is correct.
