Answer:
x^4 - 16x^3 + 96x^2 -256x + 256
Step-by-step explanation:
The coefficients of this using the pascal triangle is ;
1 4 6 4 1
Thus, we have that;
1(x^4•(-4)^0) + 4(x^3)(-4)^1 + 6(x^2)(-4^2) + 4(x^1)(-4)^3 + 1(x^0)(-4)^4
= x^4 - 16x^3 + 96x^2 -256x + 256
Answer:
963 hours
Step-by-step explanation:
I subtracted 20 from the 981
Considering that the shaded area is the part of the semi circle outside the triangle:
Area of circle= Pi x radius2 (this means radius squared)
Area of triangle= 1/2 x base x height
1/2 (because it is a semi circle) x 3.14 (in replacement of pi as directed by question) x 9squared= 127.17
127.17 - (1/2 x 18 x 9) = 46.17cmsquared
9.876 × 10^8
