Starting from the camp at c, tim takes a bearing of a mountain and notes it to be 25°. he then walks 5 km to the hut at h and takes a second bearing, 345°

a) work out the angles in the triangle.
b) from the mountain at m, what is the bearing of the camp?
c) how far is it from the camp to the mountain?
d) tim walks back to camp from the hut. what bearing does he follow?

After t seconds, a ball tossed in the air from the ground level reaches a height of h feet given by the equation h = 144t-16t^2. after how many seconds will the ball hit the ground before rebounding?

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

Circle d circumscribes abc and abe. which statements about the triangles are true? statement i: the perpendicular bisectors of abc intersect at the same point as those of abe. statement ii: the distance from c to d is the same as the distance from d to e. statement iii: bisects cde. statement iv: the angle bisectors of abc intersect at the same point as those of abe. a. i only b. i and ii c. ii and iv d. i and iii e. iii and iv
