What is the sum of the geometric series 2^0 + 2^1 + 2^2 + 2^3 + 2^3 + 2^4 + … + 2^9?
mars1129 [50]
The nth term is
an=a1(r)^(n-1)
an=1(2)^(n-1)
a1=1
r=2

the sum of a geometric seequence is
S_{n}=\frac{a_{1}(1-r^{n})}{1-r}
a1=1
r=2
we want to find S_{10} (since we minus 1, the highest exponet is 9 so add 1 to make it correct)

S_{10}=\frac{1(1-2^{10})}{1-2}
S_{10}=\frac{(1-1024}{-1}
S_{10}=\frac{(-1023}{-1}
S_{10}=1023

Vikentia [17]
The correct answer is B. cm3

This is saying "centimeters cubed", and is true because you are multiplying 3 dimensions of centimeters, width*length*height, to get the answer. Thus, you are multiplying the numbers <em>and </em>the units. 30*30*25 and cm*cm*cm

find the volume of the cone. either enter exact answer in terms of pi or use 3.14 for pi and round your final answer to the near
SCORPION-xisa [38]

Answer:

6\pi u^3 = 18.8u^3

Step-by-step explanation:

the information we have is:

  • the radius of the circle in the base: r=3u (u for units)
  • and the height of the cone: h=2u

to find the volume we need the formula for the volume of a cone:

V=\frac{\pi r^2h}{3}

where r is the radius and h is the height.

Substituting the known values to find the volume:

V=\frac{\pi (3u)^2(2u)}{3} \\\\V=\frac{\pi (9u^2)(2u)}{3}\\ \\V=\frac{18\pi u^3}{3}\\ \\V=6\pi u^3

the volume in terms of \pi is 6\pi u^3

and if we substitute the value of pi: \pi=3.14 we get:

V=6(3.14)u^3\\V=18.8u^3
