Answer:

$1,165\frac{1}{3}\ yd$

Step-by-step explanation:

In this problem we have a regular octagonal barrier (That means that all the length side are equal)

Find out the perimeter of the barrier

The perimeter is equal to

$P=8b$

where

b is the length side of the barrier

we have

$b=145\frac{2}{3}\ yd= 145+\frac{2}{3}=\frac{437}{3}\ yd$

substitute in the formula of perimeter

$P=8(\frac{437}{3})=\frac{3,496}{3}\ yd$

Convert to mixed number

$\frac{3,496}{3}\ yd=\frac{3,495}{3}+\frac{1}{3}=1,165\frac{1}{3}\ yd$

Simplify the expression. (x^2 - 9)/(x^2 + 2x - 15)

tia_tia [17]

Answer:

We have

$\frac{x^2-9}{x^2+2x-15}$

$\frac{\left(x+3\right)\left(x-3\right)}{x^2+2x-15}$

$\frac{\left(x+3\right)\left(x-3\right)}{\left(x-3\right)\left(x+5\right)}$

$\frac{x+3}{x+5}$

∴The answer is D

Jlenok [28]

1/2 because, if you have a total of 2 and you take away (or subtract in other words) 1 1/2 which is what they ate you get 1/2.

2= 2/1+ 4/2
4/2-1/2=1/2

) Consider the following probability density function of the random variable X. f(x) = k(2x + 3x2 ), 0 ≤ x ≤ 2. (i) Determine th

julia-pushkina [17]

I assume $f(x)=0$ otherwise. If $f(x)$ is indeed a proper PDF, then its integral over the support of $X$ is 1.

$\displaystyle \int_{-\infty}^\infty f(x) \, dx = k \int_0^2 (2x + 3x^2) \, dx = 1$

Compute the integral.

$\displaystyle \int_0^2 (2x + 3x^2) \, dx = (x^2 + x^3)\bigg|_{x=0}^{x=2} = (2^2 + 2^3) - (0^2 + 0^3) = 12$

Then

$12k = 1 \implies \boxed{k=\dfrac1{12}}$
