Product is the result of multiplying the numbers, so the <span>product of 8/15, 6/5,1/3 means that we have to multiply the three numbers, like this:

\frac{8}{15} * \frac{6}{5} * \frac{1}{3}
let's make them into one fraction:
</span><span>
\frac{8*6*1}{15*5*3}


We can simplyfy:
</span>
<span>\frac{8*6}{15*5*3}

</span>
<span>\frac{8*2}{15*5}

and multiply:
</span>
<span>\frac{16}{75}

and this is the correct answer!</span>

How to know if a problem is permutation or combination?
vredina [299]
If the order matters it is a permutation. For example: if you are selecting 3 people to be on a committee it doesn't matter what order you select them, but if you're selecting three people to be president, vice president, and secretary the order in which you choose them matters the first person being president, the second person being vice president, and the third person be secretary

1. Find the measure of the side indicated (x). Round to the nearest tenth. Show your work to support your
lidiya [134]

Answer:

Is this for a Trig class?  just wondering

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

we want to find the Hypotenuse (Hyp)  and are given an angle and the adjacent side (adj)  sooo use  CAH  , b/c it has all of the pieces

Cos(37) = Adj / Hyp

Cos(37) = 11 / Hyp

swap  Cos(37) and Hyp... an algebra trick you should know from college algebra or where ever you learned algebra

Hyp = 11 / Cos(37)

now solve with your handy TI 83 / 84 / 89   calculator :)  if you don't have one go get one . :D get the 89 if  you are going into engineering classes...  the 83 /84 if not. (obviously there are many many other good choices, i'm not really a calculator salesman on the side :D )

Hyp = 13.77349...

Hyp = 13.8 ( rounded to nearest 10th )  :)

Lisa and Joey are each saving money for their prom. Lisa’s total amount of money is represented by the function f(x)=20-13x. The
crimeas [40]

Answer:

2 weeks

Step-by-step explanation:

Given in the question that,

Equation that represent Lisa's total amount of money

f(x) = 20 - 13x

Equation that represent Joey's total amount of money

g(x) = x² - 10

To find weeks, x, after which they will have same amount of money, we will equate both equation

<h3>20 - 13x =  x² - 10</h3>

x² - 10 - 20 + 13x = 0

x² - 30 + 13x = 0

x² + 13x - 30 = 0

(x - 2)(x + 15) = 0

x = 2 or x = -15

Weeks, x, can not be negative so we will reject x = -15

Hence, after 2nd week Lisa and Joey will have the same amount of money save.
