The width of a rectangle is 13 inchs more than 5 times the length. if x represents the length, write an algebraic expression in

terms of x that represents the perimeter of the rectangle. simplify the expression.

perimeter is 2L+2W

problem states width = 5L+13

so plug that in for w:

P=2L+2(5L+13)

now simplify

P=2L+10L+26

P=12L+26

What symbol is used for the arithmetic mean when it is a sample statistic? What symbol is used when the arithmetic mean is a pop

Andru [333]

Answer:

for sample = xbar

population = μ

Step-by-step explanation:

The arithmetic mean for sample can be represented by xbar and it can be calculated as

xbar=∑xi/n

Where xi represents data values and n represents number of data values in a sample.

The arithmetic mean for population can be represented by μ and it can be calculated as

μ=∑xi/N

Where xi represents data values and N represents number of data values in a population.

Find the minimum or maximum of the function. Describe the domain/range in interval notation y=6x^2-1

Margarita [4]

max is at vertex

in form $y=ax^2+bx+c$

the x value of the vertex is $\frac{-b}{2a}$

given, $y=6x^2-1$

a=6, b=0

the x value of the vertex is -0/(2*6)=0

the y value is $y=6(0)^2-1=0-1=-1$

so vertex is at (0,-1)

since the value of a is positive, the parabola opens up and the vertex is a minimum value of the function

therefore that value is the smallest value the function can be

domain=numbesr you can use for x

range=numbesr you get out of inputting the domain

domain=all real numbers

range is {y | y≥-1} since y=-1 is the minimum

A quadrilateral has two angles that measure 222° and 81°. The other two angles are in a ratio of 6:13. What are the measures of

hram777 [196]

$\sf\huge\underline{\star Solution:-}$

$\rightarrow$ <u>Ratio of two angles are 6:13.</u>

So, let the one angle be $\sf{6x}$ and another be $\sf{13x.}$

As we know that,

Sum of all interior angles of a quadrilateral = $\sf\pink{360°.}$

So let's sum up the given angles,

$\rightarrow$ $\sf{222°+81°+6x+13x \:=\: 360°}$

$\rightarrow$ $\sf{303+19x \:=\: 360°}$

$\rightarrow$ $\sf{19x \:=\: 360-303}$

$\rightarrow$ $\sf{19x \:=\: 57}$

$\rightarrow$ $\sf{x \:=\: \frac{19}{57}}$

$\rightarrow$ $\sf{x \:=\: 3}$

Hence, $\sf{x \:=\: 3}$

So, First angle $\sf{= \:6x\: = \:6×3 \:=}$ $\sf\purple{18°.}$

Second angle $\sf{= \:13x\: = \:13×3 \:=}$ $\sf\purple{39°.}$
