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

Answer:

C) -5 is located to the LEFT of 2

Step-by-step explanation:

On a number line, of course the negatives (-) are to the left while the positives (+) are to the right, so since -5 is negative, and 2 is positive, -5 is located to the LEFT of 2.

Hope this helps! :)

Find the 4th term if the sequend in which a1 = 2 and a n+1 = -4a n + 2

pshichka [43]

$a_n_+_1=-4a_n_+_2$

dividing both sides by -4, we get:

$a_n_+_2=- \frac{a_n_+_1}{4}$

this means, each term is its previous term divided by -4.

now we can construct the sequence as follows:

$a_1=2$

$a_2=- \frac{a_1}{4}= - \frac{2}{4}= -\frac{1}{2}$

$a_3=- \frac{a_2}{4} =- \frac{ \frac{1}{2} }{4}=- \frac{1}{8}$

$a_4=- \frac{a_3}{4}=- \frac{ \frac{1}{8} }{4}=- \frac{1}{32}$

Answer: the last term is -1/32
