Tan 20 = opposite side/ adjacent side = height/distance
tan 20 = height / 1000
1000 tan 20o = height You can finish.......
price per item would be lower
The ladder and the building and the ground form a right triangle will ladder being the hypotenuse....
pythagorean theorem hyp2 = 252 + d2
41^2 - 25^2 = d^2 d =~~ 32 ft
Where the denominator approaches zero there will be a vertical asymtope.....
since there are 17 heads there are 17 animals so far in our count
20 legs means 5 cows
then there are 17-5 = 12 octipi
196 tentacles 12 octipi * 8 = 96 tentacles are octipi the remaining tentacles are jellyfishes 196 - 96 = 100
100 / 20 = 5 jellyfish
total 22 animals
The 'x' coordiante of the parabola will be - b / 2a = - -6/(2*3/4) use this value in the quadratic to calculate the 'y' coordinate of the vertex.
Here is a Venndiagram to help you out.....
h will be ground level = 0 when the ball comes down
0 = -16t^2 + 60 t + 3 Quadratic formula shws t = 15/8 +- sqrt (237)/8 <====== throw out the negative 't' value
find h when t = 6.6
h = -16(6.6)^2 + 60 (6.6) + 3 I'll let you finish....
