What is the exact of the expressions square root of 180 - square root of 125 + square root of 5
Ivenika [448]
\bf \sqrt{180}-\sqrt{125}+\sqrt{5}\qquad 
\begin{cases}
180=2\cdot 2\cdot 3\cdot 3\cdot 5\\
\qquad 2^2\cdot 3^2\cdot 5\\
\qquad (2\cdot 3)^2\cdot 5\\
\qquad 6^2\cdot 5\\
125=5\cdot 5\cdot 5\\
\qquad 5^2\cdot 5
\end{cases}
\\\\\\
\sqrt{6^2\cdot 5}-\sqrt{5^2\cdot 5}+\sqrt{5}\implies 6\sqrt{5}-5\sqrt{5}+\sqrt{5}\implies 2\sqrt{5}

Svetach [21]

Answers:

Answer for A is 1

Answer for B is 3

Answer for C is 0.5

Answer for D is Table.

Step by step explanation:

Figure shown graph of a line

Table of x and y value are given as

X    Y

0    3

1     6

2    9

3    12

The equation of a line is given as y=0.5x+1

QA). What is the slope of the line in the graph

Ans.

The slope is given as s=\frac{Y2-Y1}{X2-X1}

In the graph, the line passing through points (0,5)(-5,0)

The slope of a line:

s=\frac{Y2-Y1}{X2-X1}

s=\frac{0-5}{(-5)-0}

s=1

The slope of the line in the graph is 1

QB). What is the slope of the line in the table

Ans.

The slope is given as s=\frac{Y2-Y1}{X2-X1}

In the table, the line passing through points (0,3)(1,6)

The slope of a line:

s=\frac{Y2-Y1}{X2-X1}

s=\frac{6-3}{(1-0}

s=3

The slope of the line in the table is 3

QC). What is the slope of the line in the equation

Ans.

The equation of a line is given as y=mx+c

The equation of a line is y=0.5x+1

Where m= slope

On comparing both the equation we get,

m=0.5

The slope of line in the equation is 0.5

QD). Which has the greatest rate of change

Ans.

The slope of the line in the graph is 1

The slope of the line in the table is 3

The slope of the line in the equation is 0.5

There, Rate of change is also called as the slope and it is greatest in case of the table.

What is the lower quartile of the following set? 28, 45, 12, 34, 36, 45, 19, 20 28.5 19.5 19 28
aleksandr82 [10.1K]
To find the lower quartile take the number of terms=n=12
to find the lower quartile take the equation (n+1)/4= 3.25
this means that the lower quartile will be at the 3.25th position int he sequence when all the terms are ordered from smallest to largest. so when ordered: 12  19  19  19.5  20  28  28   28.5   34   36   45   45
so the lower quartile is between 19 and 19.5 exactly 19.125
