For

S= \frac{a+b+c}{2}
the area is
area= \sqrt{S(S-a)(s-b)(s-c)}

find S
S=(10+11+12)/2=(33)/2=16.5
area= \sqrt{16.5(16.5-10)(16.5-11)(16.5-12)}
area= \sqrt{16.5(6.5)(5.5)(4.5)}
area= \sqrt{2654.444}
area=51.5212
rounded
52 square inches

Let f ( x , y )=5 x and let C be the segment of the parabola y = 2 x squared joining O( 0 , 0 ) and P( 1 , 2 ). a. Find a parame
taurus [48]

a. We can parameterize C by

x=t

y=2t^2

with 0\le t\le1. Then

\displaystyle\int_C5x\,\mathrm dS=\int_0^15t\sqrt{1+16t^2}\,\mathrm dt=\dfrac5{48}(17^{3/2}-1)

b. We can parameterize the opposite direction by instead setting

x=1-t

y=2(1-t)^2

with 0\le t\le 1. Then

\displaystyle\int_C5x\,\mathrm dS=\int_0^15(1-t)\sqrt{1+16(1-t)^2}\,\mathrm dt=-\int_1^05u\sqrt{1+16u^2}\,\mathrm dt=\int_0^15u\sqrt{1+16u^2}\,\mathrm du

which gives the same value as in part (a).

Suppose you are studying a population with the following characteristics: Birth rate = 14 per 1,000/year Death rate = 6 per 1,00
Nutka1998 [239]

Answer:

 12 per 1,000 / year would be population growth

Step-by-step explanation:

To know the population growth it is important to know what it contributes to its growth and that it decreases it.

Birth rate ==> increases growth

Death rate ==> decreases growth

Immigration rate ==> increases growth

Emigration rate ==> decreases growth

Now it only remains to add those that increase growth and subtract those that decrease, like this:

 14 per 1,000 / year - 6 per 1,000 / year + 5 per 1,000 / year - 1 per 1,000 / year = 12 per 1,000 / year

 12 per 1,000 / year would be population growth
