To get the answer, multiply 9.99 x 17.4 yards. That will give you the answer 173.826. That rounds to 173.83

A countrys population in 1990 was 145 million. In 1998 it was 151 million. Estimate the population in 2015 using the exponential

alexandr402 [8]

Answer:

The population in 2015 will be 165 million.

Step-by-step explanation:

The exponential growth formula is given by:

$f(t) = a(1 + r)^{\Delta t}$

Where:

a: is the initial population

r: is the rate of increase

Δt: is the time

With the initial information we can find the rate:

$151 = 145(1 + r)^{1998-1990}$

Using logarithm:

$ln(151) = ln(145) + 8[ln(1 + r)]$

$ln(1 + r) = \frac{ln(151) - ln(145)}{8}$

$ln(1 + r) = 5.0683 \cdot 10^{-3}$

Using exponential:

$e^{ln(1 + r)} = e^{5.0683 \cdot 10^{-3}}$

$r = 5.081 \cdot 10^{-3}$

Now, we can find the estimated population in 2015:

$f(t) = 151(1 + 5.081 \cdot 10^{-3})^{2015-1998}$

$f(t) = 165$

Therefore, the population in 2015 will be 165 million.

I hope it helps you!

Answer:

The diagonal length of a diskette is $\sqrt{50}$

Step-by-step explanation:

Given:

sides = 5 inches

To Find:

diagonal length of a diskette = ?

Solution:

The diskette is in the shape of square

So the diagonal of square = $s \sqrt{2}$

where s is the side of the square

On substituting the square value

The diagonal of diskette = $(5) \sqrt{2}$

The diagonal of diskette = $( \sqrt{5} )( \sqrt{5} )( \sqrt{2} )$ $[\because 5 = \sqrt{5} \cdot \sqrt{5} ]$

The diagonal of diskette = $\sqrt{50}$
