Answer:

Step-by-step explanation:

2√5*√19=2√95≈19.494≈19.49≈19.5

if you want exact then 2√95

if three decimal places then 19.494,if two decimal places then 19.49 ,if one decimal place then 19.5

Answer:

The measures of the intercepts arcs are $58\°$ and $122\°$

Step-by-step explanation:

we know that

The measurement of the outer angle is the semi-difference of the arcs which comprises

Let

x,y -----> the intercepts arcs

$x+y=180\°$ ----> equation A

$32\°=\frac{1}{2}(x-y)$

$64\°=(x-y)$

$x=64\°+y$ ------> equation B

substitute equation B in equation A

$(64\°+y)+y=180\°$

$64\°+2y=180\°$

$2y=180\°-64\°$

$y=116\°/2=58\°$

Find the value of x

$x=64\°+58\°=122\°$

therefore

The measures of the intercepts arcs are $58\°$ and $122\°$

The slope of the graphed line is. Which formulas represent the line that is graphed? Check all that apply. Y – 1 = (x – 2) y – 2

IceJOKER [234]

The formula or equation which represent the graphed line with point (1,2) (4,4) and slope 2/3 are,

$(y-2)=\dfrac{2}{3}(x-1)\\$

$(y-4)=\dfrac{2}{3}(x-4)\\$

<h3>What is the equation of a graphed line?</h3>

The equation of a graphed line is a way to represent the line which lies on a point on the xy-coordinated with and informed about the steepness and the direction of the line.

The standard form of the equation of a graphed line can be given as,

$y=mx+c$

Here, (c) is the y intercept of the line and (m) is the slope of the line.

Here, the slope of the graphed line is 2/3. The graph for this problem is attached below.

The two point in the graph below are (1,2) and (4,4). Then the equation of the line, for this two points with slope 2/3 can be given as,

$(y-2)=\dfrac{2}{3}(x-1)\\$

Using the points (4,4), we get,

$(y-4)=\dfrac{2}{3}(x-4)\\$

Thus, the formula or equation which represent the graphed line with point (1,2) (4,4) and slope 2/3 are,

$(y-2)=\dfrac{2}{3}(x-1)\\$

$(y-4)=\dfrac{2}{3}(x-4)\\$

Help me with this problem please

Katena32 [7]

Answer:

$(a)\ A_1 = s^2$

$(b)\ A_2 = 4s^2$

Step-by-step explanation:

Given

Small Square:

$Dimension: s$

Large Square:

$Dimension: 2s$ i.e. twice as long as the small square

Solving (a): The area of the small square.

This is calculated as

$Area = Length^2$

So, we have:

$A_1 = s^2$

Solving (b): The area of the large square.

This is calculated as

$Area = Length^2$

So, we have:

$A_2 = (2s)^2$

$A_2 = 4s^2$

Solving (c): Number of small square to cover the large square

To do this, we simply divide their areas.

Let n represents the required number; n is calculated as:

$n = \frac{A_2}{A_1}$

$n = \frac{4s^2}{s^2}$

$n = 4$

Hence, 4 small squares is required to cover the large square
