A freshwater pipeline is to be run from a source on the edge of a lake to a community on an island miles​ offshore, as shown in the figure. Answer the questions that follow. A right triangle has a vertical side labeled 4 miles, a horizontal side labeled x, and an unlabeled hypotenuse. The angle opposite side x is labeled Island. A horizontal line extends from the horizontal side to the Source. The horizontal distance from the island to the source is 10 miles. The horizontal distance from the source to the hypotenuse of the triangle is labeled 10 minus x. 4 10 miles miles Island Source ​(A) If it costs times as much to lay pipe in the lake as it does on​ land, what should x be​ (in miles) to minimize the total cost of this​ project? x nothing miles ​(Round to the nearest tenth as​ needed.)

1 ?

step-by-step explanation:

u said 1+1+1+1+1+1+1+1+1+1+1+1*0 so ur adding 1 but then multiplying by 0 so its 0 but then u said 1*0+1 so now ur adding 1 so the answer is juan ?

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
