There are 15 people in the chorus. Each year, the number of people in the chorus increases by 12%.

1 answer:

8 0

This has already been answered before but...
Part AChorus:Expontential growth = b*a^x b = 15a = 1.12 (a= r+1), r = 12%
Which gives a function of f(x) = 15*1.12^x

BandLinear growth = ax+ba = 2b = 30
Which gives a function of g(x)=2x+30
Part B:f(9) = 15*1.12^9 = 41.59g(9) = 2*9+30 = 48
Part C:This is probably problem solving, where you're allowed to use calculators and other softwares.
Therefore you can use different softwares, and make f(x) = g(x).I did this, and got it to 10.95427141

You have 2 triangles and 3 rectangles.
Start with a triangle:
area is base side * height / 2 -> 4 * 3 / 2 = 6
The other triangle has the same area: 6

First rectangle: side * other side -> 7 * 5 = 35
Second rectangle: 7 * 4 = 28
Third rectangle: 7 * 3 = 21

Now simply add all this together: 6+6+35+28+21 = 96

What are the points of discontinutity y=(x-3)/x^2-12x+27

madreJ [45]

Answer:

$(3, -\frac{1}{6})$

Step-by-step explanation:

We can rewrite the equation as

$y = \frac{x - 3}{(x - 3)(x - 9)}$

Notice that we have $x - 3$ in both the numerator and the denominator, so it looks like we can divide it out. However, what if $x - 3$ is $0$ ? Then we would have $y = \frac{0}{0 \times (x - 9)} = \frac{0}{0}$ , which is undefined. So although it looks like the numerator and denominator can be simplified, the resulting function we would get from simplification would not have the same behavior as this one (since such a function would be defined for $x = 3$ , but this one is not).

A point of discontinuity refers to a particular point which is included in the simplified function, but which is not included in the original one. In this case, the point which is not included in the unsimplified function is at $x = 3$ . In the simplified version of the function, if we plug in $x = 3$ , we get

$y = \frac{1}{((3) - 9)} = -\frac{1}{6}$

So the point $(3, -\frac{1}{6})$ is our only point of discontinuity.

It's also important to distinguish between specific points of discontinuity and vertical asymptotes. This function also has a vertical asymptote at $x = 9$ (since it causes the denominator to be 0), but the difference in behavior is that in the case of the asymptote, only the denominator becomes 0 for a specific value of $x$

A soccer team made 76 penalty shots out of 100.Which ratio represents successful penalty shots to missed penalty shots?

almond37 [142]

Sense we are wanting to find <u>how many were miss</u>, then, we are practically going to subtract the following:

$\boxed{76-100}= \ \left[\begin{array}{ccc}\bf{24\end{array}\right]$

So, from this begin understood, we would then combine both the penalties that were shotted, to the onces that weren't.

So, b subtracting these both, we would grab the result, and then smash that with the number of the penalties that were made in.

Your answer: $\boxed{\bf{76:24}}$
