jeka57 [31]

Answer:

k = -3

Step-by-step explanation:

f(x) = -2x+1

g(x) = 6x - 3

=> g(x) = k.f(x)

6x - 3 = k(-2x+1)

k = (6x-3)/(-2x+1)

= 3(2x-1)/-1(2x-1)

k = 3/(-1) = -3

Answer:

330ft²

Step-by-step explanation:

Area of figure = Area of rectangle + Area of semicircle

                       =            lb                +   pi r²/2

                       =         10 x 8             +  3.1 x 4 x 4/2 ( as 8 is diameter)

                       =          80 ft²               +  248  ft²

                       =  328 ft² => 330ft²
