Multiply. 5/8 x (-8/9) = (type an integer or a simplified fraction.)

i believe the answer is 323 ft

step-by-step explanation:

you can use a^2+ b^2=c^2

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.

the answer is  

d.

121π mi^2

hope you got it chief
