Step-by-step explanation:
when 11 is decreased by a number, the result is 413
Volume of the cone:
V = 3.14 x 3^2 x 9/3 = 84.78
Volume of half sphere on top of cone:
V = (4/3 x 3.14 x 3^3 )/2 = 56.52
Total volume = 56.52 + 84.78 = 141.3 cm^3
we have that
−4+8−16+32−.....
a1=-2*(-2)-----> -4
a2=-4*(-2)-----> +8
a3=+8*(-2)-----> -16
a4=-16*(-2)----> +32
a5=+32*(-2)----> -64
a6=-64*(-2)-----> +128
a7=+128*(-2)-----> -256
The sum of the first 7 terms of the series is
<span>[a1+a2+a3+a4+a5+a6+a7]-----> [-4+8-16+32-64+128-256]------->
-172</span>
<span>
the answer is -172</span>
1. 2.6 x 10^-2, 6.2 x 10^-1, 3.5 x 10^2, 1.5 x 10^4
2.6 x 10^-2, 6.2 x 10^-1, 3.5 x 10^2, 1.5 x 10^4
2.6 x 10^-2, 6.2 x 10^-1, 3.5 x 10^2, 1.5 x 10^4
2.6 x 10^-2, 6.2 x 10^-1, 3.5 x 10^2, 10^4, 1.5 x 10^4
2. 6^5
3. 9^9
Because the boarder goes around all edges, 6 in must be subtracted from 6ft and 4ft.
6ft - 6in = 5.5 ft
4ft - 6in = 3.5 ft
Area of the bulletin board: (5.5)(3.5) = 19.25 ft
