Answer:

Step-by-step explanation:

Draw a picture Of a triangle ABC , BC as Base connect D on AB , and E on AC together with a line parallel to Base BC

Λ if using one of the 5 postulate of Euclid:

"If 2 parallel line intersected by a third line, the interior angles are equal."

< B = < D , and < C = < E .

Triangle ABC is similar to ADE

AD/ Ab = AC / AB

Answer:

p = 497 ( to the nearest whole number)

Step-by-step explanation:

In order to do this calculation, we will apply the principle of accounting, where a certain amount is compounded periodically and yielding a future value. Compound interest is used because the percentage growth rate is added on the new amount gotten each year, and not on the first or original amount.

Hence:

FV = PV × $(1+ \frac{r}{n}) ^{n*t}$

where FV = future value = population in 2020 = 810

PV = present value = population in 2010 = p

r = percentage growth rate in decimal = 5% = 5/100 = 0.05

n = growth rate period per year = once = 1

t = time in years = 2010 to 2020 = 10 years

∴ $810 = p * (1+ \frac{0.05}{1}) ^{1*10}$

$810 = p * (1.05) ^{10}\\810= p(1.6289)$ (dividing both sides by 1.6289)

p = 810 ÷ 1.6289 = 497.2 = 497 (to the nearest whole number)

∴ population in 2010 = 497

Answer:

The sum of a and b is 12.

Step-by-step explanation:

Try drawing this figure. ABCD would actually be a triangle, rather than the common quadrilateral you would expect - considering there are 4 points plotted. Therefore, we would have to find the distance between respective points ( 0, 1 ) and ( 2, 5 ) / ( 2, 5 ) and ( 7, 0 ) / ( 0, 1 ) and ( 7, 0 ). Let's apply the distance formula and calculate the distance between each point, therefore determining the perimeter.

Distance between points ( 0, 1 ) and ( 2, 5 )

= $\sqrt{(2-0)^2+(5-1)^2}$

= $\sqrt{(2)^2+(4)^2}$

= $\sqrt{4+16}$

= $\sqrt{20}$ = $2\sqrt{5}$

Distance between points ( 2, 5 ) and ( 7, 0 )

= $\sqrt{(7-2)^2+(0-5)^2}$

= $\sqrt{5^2+(-5)^2}$

= $\sqrt{25+25}$

= $\sqrt{50}$ = $5\sqrt{2}$

And you can calculate the distance between points ( 0, 1 ) and ( 7, 0 ) to be exactly $5\sqrt{2}$ as well. Therefore, you can say that the perimeter of this triangle is $2(5\sqrt{2}) + 2\sqrt{5}$ = $10\sqrt{2} + 2\sqrt{5}$ . Note that this is similar to the form we are given. Thus, a = 10, and b = 2 - making it's sum 10 + 2 = 12.
