One palm tree grew 85 inches in 5 years and a queen palm tree grew 96 inches in 8 inches which tree grew faster explain

Leviafan [203]

Answer:

The queen palm tree

Step-by-step explanation:

I think you were saying years not inches but pretty much if you divide 85 divided by 5 you get 17 but if you divided 86 divided by 8 you get 12 so 12 is less than 17.

Factor each expression<br> 1. 3n + 9<br> 2. t² + 4t<br> 3. 15 + 20x

Gnom [1K]

1... 3 (n + 3)
2... t (t + 4)
3... 5 (3 + 4x)

The trick to all of these is finding common factors, then taking them out... IT's pretty easy once you get the hang of it.

Find a power series representation for the function. (Give your power series representation centered at x=0 .) f(x)=15+x

Anna71 [15]

Answer:

$f(x) = \sum\limits^{\infty}_{n=0} \frac{-(1)^n\cdot x^n}{5^{n+1}}$

Step-by-step explanation:

Given

$f(x) = \frac{1}{5 + x}$

Required

The power series centered at $x = 0$

We have:

$f(x) = \frac{1}{5 + x}$

Factor out 5 from the denominator

$f(x) = \frac{1}{5(1 + \frac{x}{5})}$

Rewrite as:

$f(x) = \frac{\frac{1}{5}}{(1 + \frac{x}{5})}$

Further, rewrite as:

$f(x) = \frac{1}{5}(1 + \frac{x}{5})^{-1}$

Expand the bracket

$f(x) = \frac{1}{5}(1 - \frac{x}{5} + (\frac{x}{5})^2 - (\frac{x}{5})^3+..........)$

Evaluate all exponents

$f(x) = \frac{1}{5}(1 - \frac{x}{5} + \frac{x^2}{25} - \frac{x^3}{125}+......)$

Open brackets

$f(x) = \frac{1}{5} - \frac{x}{5^2} + \frac{x^2}{5^3} - \frac{x^3}{5^4}+......$

Notice the pattern as:

$f(x) = \frac{1}{5} - \frac{x}{5^2} + \frac{x^2}{5^3} - \frac{x^3}{5^4}+......\± \frac{x^n}{5^{n+1}}$

So, the power series is:

$f(x) = \sum\limits^{\infty}_{n=0} \frac{-(1)^n\cdot x^n}{5^{n+1}}$
