Answer:

The answer to your question is 19.2 feet.

Step-by-step explanation:

With the data given, we can see that we have a right triangle in the middle of the bigger one. Also, we can see that we have four triangles inside the biggest one, and all these triangles have the same size.

Then we can know the length of the three sides of:

BC = DE + DE = 3.2 + 3.2 = 6.4

AB = EF + EF = 4 + 4 = 8

AC = DF + DF = 2.4 + 2.4 = 4.8

Perimeter = BC + AB + AC = 6.4 + 8 + 4.8 = 19.2 feet

Answer:

On a basic level, crayons consist of paraffin wax and non-toxic color pigments. The pigments typically come in a powdered form, with the specific colors and amounts determined by the final color of the crayon being produced. Crayons may also contain an additive to improve the strength of the crayon.

Answer:

a. After the first bounce, the ball will be at 85% of 8 ft. After 2 bounces, it'll be at 85% of 85% of 8 feet. After 3 bounces, it'll be at (85% of) (85% of) (85% of 8 feet). You can see where this is going. After n bounces the ball will be at

$h(n) = (85\%)^n 6ft = (\frac{17}{20})^n(6ft\times 12\frac{in}{ft}) = (\frac{17}{20})^n\times72'$

b. After 8 bounces we can apply the previous formula with n = 8 to get

$h(8)=(\frac{17}{20})^8\times 72' = 19.62'$

c. The solution to this point requires using exponential and logarithm equations; a more basic way would be trial and error using the previous $h(n)$ increasing the value of n until we find a good value. I recommend using a spreadsheet for that; the condition will lead to the following inequality:

$1>(\frac{17}{20})^n\times 72$ Let's first isolate the fraction by dividing by 72.

$(\frac{17}{20})^n$ Now, to get numbers we can plug in a calculator, let's take the natural logarithm of both sides:

$ln ((\frac{17}{20})^n) < ln \frac 1{72} \rightarrow n\times ln (\frac{17}{20}) < -ln72$ . Now the two quantities are known - or easy to get with any calculator, replacing them and solving for n we get:

$-(0.16)n < - 4.27 \rightarrow n>26.31$ Now, since n is an integer - you can't have a fraction of a bounce after all, you pick the integer right after that, or n>27.
