(a) Answer The required distance is 191 yd . Explanation Given information : The following graph is been given: Formula used: d = ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2 Calculation: To find the distance around the part to the nearest yard, you to find the value distance P Q & Q R , Hence, P Q = | 10 − 50 | = 40 Q R = | 80 − 10 | = 70 Now, the distance P R , P R = ( 80 − 10 ) 2 + ( 10 − 50 ) 2 = ( 70 ) 2 + ( − 40 ) 2 = 4900 + 1600 ≈ 81 m Therefore, the total distance = 40 + 70 + 81 = 191 yd (b) To determine To find: The distance Q M to the nearest yard. Answer The required distance is 40 yd . Explanation Given information : The following graph is been given: Formula used: d = ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2 Calculation: Get the midpoint of P Q ¯ first, P Q ¯ = ( 80 + 10 2 , 50 + 10 2 ) = M ( 45 , 30 ) Hence, Q ( 10 , 10 ) and M ( 45 , 30 ) , Q M = ( 45 − 10 ) 2 + ( 30 − 10 ) 2 = 35 2 + 20 2 = 1625 = 40 yd (c) To determine To find: The time taken for jogs will be calculated. Answer The required time is 1.5 min . Explanation Given information : The average speed of a man is 150 yards per minute . The following graph is been given: Formula used: d = ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2 Calculation: Since P Q = 40 ≈ Q M = 40 Hence, M R , M R = ( 80 − 45 ) 2 + ( 10 − 30 ) 2 = 35 2 + ( − 20 ) 2 = 1625 = 40 yd And R Q = 70 & Q p = 40 Therefore, the total distance = 40 + 40 + 40 + 70 + 40 = 230 yd Now, the required time will be: t = 230 yd 150 t = 1.5 min

Question

Chapter 8.3, Problem 39E

(a)

To determine

To find: The distance around the part to the nearest yard.

(a)

Expert Solution

Answer to Problem 39E

The required distance is $191 yd$ .

Explanation of Solution

Given information: The following graph is been given:

BIG IDEAS MATH Integrated Math 1: Student Edition 2016, Chapter 8.3, Problem 39E , additional homework tip 1

Formula used: $d=(x2−x1)2+(y2−y1)2$

Calculation: To find the distance around the part to the nearest yard, you to find the value distance $PQ & QR$ ,

Hence,

$PQ=|10−50|=40QR=|80−10|=70$

Now, the distance $PR$ ,

$PR=(80−10)2+(10−50)2=(70)2+(−40)2=4900+1600≈81 m$

Therefore, the total distance $=40+70+81=191 yd$

(b)

To determine

To find: The distance $QM$ to the nearest yard.

(b)

Expert Solution

Answer to Problem 39E

The required distance is $40 yd$ .

Explanation of Solution

Given information: The following graph is been given:

BIG IDEAS MATH Integrated Math 1: Student Edition 2016, Chapter 8.3, Problem 39E , additional homework tip 2

Formula used: $d=(x2−x1)2+(y2−y1)2$

Calculation: Get the midpoint of $PQ¯$ first,

$PQ¯=(80+102,50+102)=M(45,30)$

Hence, $Q(10,10)$ and $M(45,30)$ ,

$QM=(45−10)2+(30−10)2=352+202=1625=40 yd$

(c)

To determine

To find: The time taken for jogs will be calculated.

(c)

Expert Solution

Answer to Problem 39E

The required time is $1.5 min$ .

Explanation of Solution

Given information: The average speed of a man is $150 yards per minute$ .

The following graph is been given:

BIG IDEAS MATH Integrated Math 1: Student Edition 2016, Chapter 8.3, Problem 39E , additional homework tip 3

Formula used: $d=(x2−x1)2+(y2−y1)2$

Calculation: Since $PQ=40≈QM=40$

Hence, $MR$ ,

$MR=(80−45)2+(10−30)2=352+(−20)2=1625=40 yd$

And $RQ=70 & Qp=40$

Therefore, the total distance $=40+40+40+70+40=230 yd$

Now, the required time will be:

$t=230 yd150t=1.5 min$
