Answer: Rational

Step-by-step explanation: To determine whether 1/8 is rational or irrational, remember that all fractions positive or negative are rational numbers.

Therefore, 1/8 must be a rational number

A number is rational if it can be written as the ratio of two integers.
The ratio of two integers is a fraction, and you just did it.  Your number
is the ratio of 1 to 8 .  It's about as rational as you can get.

<span>Here's a fun fact that's easy to remember:
<em>ANY</em> number that you can write down on paper, completely, with digits
and a decimal point or a fraction bar if you need them, is rational.</span>

Answer:

#2 is a ratio so you gotta add.

#3 it’s just adding it for example 2p + 5a = 7pa

The crime rate of a certain city is increasing by exactly 6% each year. If there were 550
kap26 [50]

Using an exponential function, it is found that the approximate number of crimes in the year of 2016 was of 2502.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the growth rate, as a decimal.

In this problem, there were 550 crimes in the initial year observed, and the growth rate is of 6%, hence the parameters are A(0) = 550, r = 0.06, and the equation is given by:

A(t) = A(0)(1 + r)^t

A(t) = 550(1 + 0.06)^t

A(t) = 550(1.06)^t

2016 is 26 years after 1990, hence:

A(26) = 550(1.06)^{26} \approx 2502

The approximate number of crimes in the year of 2016 was of 2502.

How to get the answer
Aleonysh [2.5K]
So this is just working with exponents, but negative exponents can be a little tricky. your example didn't do a great job of showing how you calculate negative exponents.

for #2, you have 10⁻⁶

to convert negative exponents into something that makes more sense to our brain, you can set it beneath 1:

\frac{1}{10^6}  ... or, in the event that you can't see that because you're on the app: (1)/(10⁶). so now, instead of calculating 10⁻⁶, which would probably give you a confusing decimal, you just need to figure out 10⁶ -- and positive exponents are much easier to deal with.

10⁶ = 1,000,000
BUT remember that you have to put this value beneath a 1 to account for your negative exponent and (1/1,000,000) is your answer for part A.

so, use the same steps for the rest of the problems:
1) convert negative exponent to positive exponent beneath 1
7⁻³ = (1)/(7³)
2) calculate 7³
7³ = 343
<span>3) your result is (1/343)
</span>
<span>for 12</span>⁻², again, you'll put it beneath 1 so that it becomes (1)/(12²), then you'll calculate 12² (12*12 = 144), so that your result is (1/144). that leaves the letter D for number 2, which you'll have to write into your boxes at the top.

i hope this helps! you can message me if you have any specific ones that cause you trouble and i'll do my best to help.
