It's saying that on every other stop(with even numbers)you add 2 people, and on all the other stops(odd numbers)you subtract 5 people. Be sure that you start with 18 people on the bus! Keep doing this until there is no more people on the bus!

write the product of the expression 5^4 * 5^-7 using a positive exponent, then write the product using a negative exponent

pav-90 [236]

Answer with positive exponent = $\left(\frac{1}{5}\right)^3$ or $\frac{1}{5^3}$

Answer with negative exponent = $5^{-3}$

===========================================================

Explanation:

The rule we use is

$a^b*a^c = a^{b+c}$

If we multiply two exponential expressions with the same base, then we add the exponents.

The base for each is 5. The exponents 4 and -7 add to -3.

This means

$5^4*5^{-7} = 5^{4+(-7)} = 5^{-3}$

To convert to a positive exponent, we apply the reciprocal to the base. We go from 5, aka 5/1, to 1/5.

So, $5^{-3} = \left(\frac{1}{5}\right)^3 = \frac{1^3}{5^3} = \frac{1}{5^3}$

After a lesson on exponents, Tia went home and said to her mom " I learned that 10 to the 4th power is the same as 40,000." She

Burka [1]

Answer:

The answer is "10,000".

Step-by-step explanation:

In the 10^4 can be written as 10 exponents 4, which is not equal to 40,000. Tia's opinion was incorrect because the exponential shows how much they multiply that base number.

Let's explain :

$\to 10^4 = 10 \times 10 \times 10 \times 10 \\$

$=10,000$

Geometry ( WILL GIVE BRAINY)

Step2247 [10]

Answer:

we have a rule that is (n-2)×180

while n = number of sides

exterior angle of a polygon = 360 ÷ number of sides

so 360÷25=14.4

octagon is 8 side, so as we said: (8-2)×180 = 1080

lets make an equation, we know that (n-2)×180 = the sum

so (x-2)×180=720

180x -360 = 720

180x = 1080

x=6

Suppose you buy a CD for $300 that earns 3% APR and is compounded quarterly. The CD matures in 3 years. How much will this CD be

tino4ka555 [31]

<span>Amount spent at start C = $300 Rate = 3% = 0.03 Number of periods = 3 years Future Value at the maturity FV = 300 x (1 + 0.03) ^3= 300 x 1.0927 = 328 The correct answer would be 328.14</span>
