Answer:

637.5

Step-by-step explanation:

$a_{1}=2.5=a\\a_{5}=40=ar^4\\r=2 \ \& \ a=2.5\\\text{Sum}=\frac{a(r^n-1)}{r-1}=\frac{2.5*(2^8-1)}{1}=637.5$

5. Find the coordinates of the midpoint of the segment whose endpoints are 1l(6, 4) and K(2. 8).

Cerrena [4.2K]

Answer:

5. D (4,6)

6. B (7.8)

Step-by-step explanation:

5. Add the two X coordinates (6+2) and divide that by 2 (8/2=4), do the same for the two Y coordinates (4+8=12, 12/2=6)

6. Use the distance formula $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}\\$

Input the coordinates $\sqrt{(3-8)^{2}+(8-2)^{2}$

Use the formula to solve the problem. Round to the nearest hundredth.

Zepler [3.9K]

Answer:

Volume of sphere = 4.186 cubic inches

Step-by-step explanation:

Radius of sphere = r = 1 inch

Volume of sphere = ?

The formula used is: $Volume\:of\:sphere=\frac{4}{3}\pi r^3$

Putting value of radius and π and finding volume:

$Volume\:of\:sphere=\frac{4}{3}\pi r^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=4.186 \:cubic\:in$

So, Volume of sphere = 4.186 cubic inches
