4.9x^2 - 16x = 144
4.9x^2 - 16x - 144 = 0 use quadratic formula a = 4.9 b= -16 c = - 144 x = 7.294 s or - 4.029 ( throw out)
Pretty straightforward...
for the man to get from A to B takes 5000m / 3.14 m/s = 1592.36 seconds (NOTE: 5 km = 5000 m)
the dog is travelling 9.87 m/s for all of this time
1592.36 sec * 9.87 m / sec = 15716.56 m

Plot the points.....connect the points....
a right triangle base = 15 ( from -6 to +9) height = 9 (from 6 to -3)
calculate the hypotenuse with pythagorean theorem ......or use the distance formula ...then add all of the sides
I C and E are on the line
b = y intercept = 3 slope = rise/run
start at b go UP one and over 2 (rise over run) repeatedly you will find I and E
then going LEFT down one and over two you will fine C
f( x^n + x^n) = (x^n+x^n)4 = x^8
(2x^n)4 = x^8
n = 2 g(x) = 2 degree
period is six months
interest per period .04 / 2 = .02
for the first 6 months final amount = 10000(1+.02)1 = $ 10 200
Next six months
interest is compounded annually .05
period = 1/2
now starts with 10200
10200 (1+.05)1/2 = $ 10451.89
X: It will be 2/3 of the way from -6 to 20 2/3 of 26 added to -6
Y: it will be 2/3 of distance from 19 to 3 2/ 3 * (-16) added to 19
