Answer:

MN=9.8\ m

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The <u><em>Triangle Midpoint Theorem</em></u> states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.

In this problem

Point N is the midpoint segment JL and the point M is the midpoint segment KL

so

The segment MN is joining two sides of a triangle at the midpoints of those sides

therefore

MN is parallel to side JK and is half the length of JK

MN=\frac{1}{2}JK

we have

JK=19.6\ m

substitute

MN=\frac{1}{2}(19.6)=9.8\ m

choli [55]

Answer:

It will take the 20 years for the population to quadruple.

Step-by-step explanation:

Exponential population growth:

An exponential model for population growth has the following model:

P(t) = P(0)(1+r)^t

In which P(0) is the initial population and r is the growth rate, as a decimal.

It grows with a doubling time of 10 years.

This means that P(10) = 2P(0). We use this to find r. So

P(t) = P(0)(1+r)^t

2P(0) = P(0)(1+r)^10

(1+r)^10 = 2

\sqrt[10]{(1+r)^10} = \sqrt[10]{2}

1+r = 2^{\frac{1}{10}}

1 + r = 1.0718

So

P(t) = P(0)(1+r)^t

P(t) = P(0)(1.0718)^t

Determine how long it will take for the population to quadruple.

This is t for which P(t) = 4P(0). So

P(t) = P(0)(1.0718)^t

4P(0) = P(0)(1.0718)^t

(1.0718)^t = 4

\log{(1.0718)^t} = \log{4}

t\log{1.0718} = \log{4}

t = \frac{\log{4}}{\log{1.0718}}

t = 20

It will take the 20 years for the population to quadruple.
