the height h is h(t) = 320 + 128t - 16t^2 The vertex of this parabola is at t = 4 So, figure h(4)

6/x + 6/x-5 = 1 I got to x^2 -17x +5 = 0 But I have no idea if that is right? How do I find the answer? Thanks 6/x 6/x-5 =1 multiply both sides by x x(6/x +6/x-5)= (1) x The denominator x will cancel giving: 6 + 6 --- = x -5 Now -5 into 6 = -1.2 so 6 -1.2= x x= 4.8

Hmmm. I don't buy it. You can't have x = 1/√2 , y = 41/√2 , and k = 21√2 and x^2 + (y-k)^2 = 1^2 Maybe I'll visit the figure.

My bad. I misread it. Even after looking at it several times, I still saw 21/√2 rather than 21√2.

a stone thrown upward from the top of a 320-foot cliff at 128 ft/sec eventually falls to the beach below? how long does the stone take to reach its highest point?

ABCD is a square. P is a point within ABCD such that PA=1,PB=29 and PC=41. What is area of square ABCD ?

x^2 + (y-k)^2 = (1/√2)^2 + (41/√2 - 21√2)^2 ,,,,,, 21√2 = 42/√2 = 1/2 + (-1/√2)^2 = 1/2+1/2 = 1

A woman is three times as old as her daughter, but in 12 years she will be just twice as old as her daughter. How old is the daughter now and how hold is the woman now?

When a woman is as old as her father is now, she will be five times as old as her son is now. By then, her son will be eight years older than she is now. The combined ages of her father and herself are 100 years. How old is her son?

W = 3 D W + 12 = 2 (D + 12) = 2D + 24 Solve for woman's current age (W) and her daughters current age (D) 3D + 12 = 2D + 24 D = 12

I started by placing a square of sides k so that one vertex is at B(0,0), and letting sides fall on the x and y axes so the other vertices are C(k,0), D(k,k) and A(0,k) I let point P be (x,y) PO = 29 ----> x^2 + y^2 = 29^2 PA = 1 -----> x^2 + (y-k)^2 = 1^2 PC = 41 ----&...
