Answer:

PA+AR=PR

AR= PR- PA

AR= 8x+14-(7x-11)

AR= 8x+14-7x+11

AR= x+25

Now, if A is midpoint of PR, then

PA=AR

7x-11= x+25

6x=36

x=6

Put value of x in AR

AR= 6+25= 31

Hope this will help:)

Answer: x+25

Step-by-step explanation:

Here.

PR = 8x+14

& PA = 7x-11

and A is the mid point of PR

so according to condition , PR - PA = AR

⇒ 8x + 14 -(7x -11) =AR

⇒8x +14 -7x + 11 = AR

∴ AR = x+25

The initial population of a town is 3600, and it grows with a doubling time of 10 years. What will the population be in 8 year

shutvik [7]

If is doubles in 10 years, then you should divide 2 by 10 to get the yearly growth rate equaling 1/5. Multiply 1/5 by 8 equals 8/5= 1 3/5. multiply that number by 3600, giving you 5,760.

Company XYZ closed at $46.07 per share with a P/E ratio of 16.66. Answer the following questions.

Andrew [12]

The amount of earnings per share is $2.77.

<h3>Earnings per share</h3>

a. Earnings per share = price per share / (P/E) ratio

Earnings per share = $46.07 / 16.66

Earnings per share= $2.77

B. Overpriced or underpriced stock

At P/E ratio = 12

Earnings per share = $46.07 / 12

Earnings per share = $3.84

Earning yield = ( Earning per share / market value )× 100

Earning yield = (3.84 / $46.07 ) × 100

Earning yield = 8.34%

At P/E ratio = 13

Earnings per share = $46.07 / 13

Earnings per share = $3.54

Earning Yield= (3.54 / 46.07 ) × 100

Earning Yield= 7.68%

At P/E ratio = 14

Earnings per share = $46.07 / 14

Earnings per share = $ 3.3

Earnings yield= ( 3.3 / 46.07 )×100

Earnings yield= 7.16%

Average of earning yield given P/E ratio is 12-14

Average of earning yield= ( 8.34 + 7.68 + 7.16 ) / 3

Average of earning yield= 7.73%

Earning yield = ( Earning per share / market value ) × 100

Earning yield= ( 2.77 / 46.07 ) ×100

Earning yield = 6.01%

Hence, Based on the above the stock is underpriced.

A ray that contains a point that is equidistant from both sides of the angle. *

seraphim [82]

<span>Consider a angle â BAC and the point D on its defector Assume that DB is perpendicular to AB and DC is perpendicular to AC. Lets prove DB and DC are congruent (that is point D is equidistant from sides of an angle â BAC Proof Consider triangles Î”ADB and Î”ADC Both are right angle, â ABD= â ACD=90 degree They have congruent acute angle â BAD and â CAD( since AD is angle bisector) They share hypotenuse AD therefore these right angle are congruent by two angle and sides and, therefore, their sides DB and DC are congruent too, as luing across congruent angles</span>
