Answer:

The square root of 244 is 15.62 ( up-to 2 decimal places)

Step-by-step explanation:

Following is the division method for square root of 244 with rules as follows:

Make pairs of the given digit starting from right (unit place). They will be calculated one by one as formed in pairs/singles.
Digit added for divisor and quotient will be same at each step.
Each next dividend will be formed by subtracting product of divisor and quotient from first digit/pair.
Each next divisor will be formed by taking two times of previous quotient and annexing it with suitable digit that gives equal to or less than the dividend.

Following solution gives square root of 244:

Answer:

$P(t) = P(0)e^{0.0693t}$

Step-by-step explanation:

The population of a community is known to increase at a rate proportional to the number of people present at time t.

This means that the population growth is modeled by the following differential equation:

$\frac{dP(t)}{dt} = rP(t)$

Which has the following solution:

$P(t) = P(0)e^{rt}$

In which P(t) is the population after t years, P(0) is the initial population and r is the growth rate.

The population has doubled in 10 years

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

$P(t) = P(0)e^{rt}$

$2P(0) = P(0)e^{10r}$

$e^{10r} = 2$

$\ln{e^{10r}} = \ln{2}$

$10r = \ln{2}$

$r = \frac{\ln{2}}{10}$

$r = 0.0693$

So the equation that will estimate the population of the community in t years is:

$P(t) = P(0)e^{0.0693t}$

Find the area of each figure. (Or as much as u can)

Answer:

7. 91 m²

8. 56 in²

9. 105 in²

10. 135 m²

Step-by-step explanation:

The formula for the area of a triangle is ...

A = 1/2bh

where b is the base length, and h is the height perpendicular to the base.

The formula for the area of a trapezoid is ...

A= 1/2(b1 +b2)h

where b1 and b2 are the lengths of the parallel bases, and h is the perpendicular distance between them. Note that this formula is virtually identical to the triangle formula, with the triangle 'b' being replaced by (b1+b2).

Fill in the numbers and do the arithmetic. The result is shown in the attachment. (We have used the triangle formula for all, with b1+b2 being used for 'b' to find the area of the trapezoids.)

7. A = 1/2(14 m)(13 m) = 91 m²

8. 56 in²

9. A = 1/2(14 +16 in)(7 in) = 105 in²

10. 135 m²
