8x8x8x8x8 is the answer. The 5 as the exponent means that you are multiplying 8 by itself 5 times.

Your answer is: 8*8*8*8*8 because 8^5 is 8 to the fifth power, which means 8 times itself 5 times.

HELP !! Find the x with the details in this picture^^

zvonat [6]

Answer:

x = 3.9

Step-by-step explanation:

So the whole angle PQS = 111 degrees

it gave you part of it so subtract that off . 111 - 72 = 39 degrees

10 times what equals about 39 degrees.

39/ 10 = 3.9

Heather runs round a circular track many times each day.

slamgirl [31]

Answer:

See explanation

Step-by-step explanation:

1. Determine the total distance heather has run in Km.

4.18km PER DAY for 197 days; 4.18 * 197 = 823.46km.

2. Can we just stop and say that this Heather chick MIGHT HAVE A PROBLEM?! Like, fr, she has run over 500 miles in half a year. . .she needs to see someone about that.

3. Divide the total distance by the distance of the track.

823.46/0.21 = 3921.23809524

4. Conclusion: Heather has run (roughly) 3,931.24 times around the track after the 197 day period of running 4.18km per day.

Given the geometric sequence where a_1 = 3 and r = √2 find a_9

sesenic [268]

To find n-therm of a geometric sequence, we are going to use the formula $a_{n} =a _{1} r^{n-1}$
where:
$a_{n}$ is the term we are looking for
$a _{1}$ is the first term
$r$ is the ratio
$n$ is the position of the number in the sequence

From the question we now that $a _{1} =3$ , $r= \sqrt{2}$ , and $n=9$ . Lets replace those values into our formula to get:
$a _{9} =3( \sqrt{2} )^{9-1}$
$a_{9} =3 \sqrt{2} ^{8}$
$a_{9} =48$

We can conclude that in our geometric sequence $a_{9} =48$ ; therefore, the answer is A.
