The land area of florida is 1×100,000+3×10,000+9×1,000+8×100+5× 10+2×1 square kilometers. write the area in standard form and word form

139852 square kilometers

1 Lakh thirty nine thousand eight hundred fifty two square kilometers.

Step-by-step explanation:

We are given that land area of Florida

We have to write area  in standard form and word form

Standard form

square kilometers

Because place value of 1 is 1 lakh, place value of 3 is 30000,9 is at thousand place , 8 at hundred place, 5 at tens place and 2 at unit place.

Word form: 1 Lakh thirty nine thousand eight hundred fifty two square kilometers.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
