Two cross roads ,each width 10m cut at right angle through the centre of a rectangular park of length 700m and breadth 300m and parallel to it's sides find the area of the roads .Also find the area of the park excluding cross roads .Give the answer in hectares

Step-by-step explanation:

Area of one  road = 700 x 10

7000 sq m

area of another road

= 300 x 10 = 3000sq m

Total area of road

= 7000 + 3000 - 10 x 10

= 9900 sq m

Area of park

= 700 x 300

= 210000 sq m

less area of road

= 210000 - 9900

= 200100 sq m

= 200100 / 10000 hectare

= 20.01 hectare.

a is the correct

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
