2. The equation D=3.59 (sqrt)h gives the distance, D, in kilometers that a person can see to the horizon from a height, h, in meters.
a. Solve this equation for h.
b. Mount Evans in the Rocky Mountain National Park, is approximately 4,450 meters in elevation. How far can you see to the horizon from the top of Mount Evans? Can you see Cheyenne, Wyoming (about 244 kilometers away)? Explain your answer.
A person is on the outer edge of a carousel with a radius of 20 feet that is rotating counterclockwise around a point that is centered at the origin. What is the exact value of the position of the rider after the carousel rotates
1.Find the distance between P(7, -4) and the line with equation x - 3y + 5 = 0 round to nearest tenth 3Y=x+5 y=(x+5)/3 -1/m = -3 y=-3x+b sub in P(7,-4) -4=-3(7)+b b=21-4 b=17 y=-3x+17 set the two equations equal. -3x+17=(x+5)/3
On a map 3/6 inch represents 60 kilometers. Distance A to B is 4 5/8 inches. Distance C to D is 5 3/5 inches. Distance E to F is 9 5/6 inches. What is the number of kilometers between A and B? What is the number of kilometers
An umbrella with a diameter of 1 m turns 22 rev every 44 seconds. If it's 1.5 m from the ground, calculate the time it takes for a drop to reach the ground and the distance away from the umbrella a person should stand so as to not

A truck moves 60 kilometers east from point A to point B. At point B, it turns back west and stops 15 kilometers away from point A. What are the total distance and total displacement of the truck? A.The total distance is 105
Okay, this is a problem that I've tried over ten times before getting a fresh problem and trying that one too. I've never gotten a correct answer and I can't figure out why it's not right. Here's the problem, "Find the distance
I need to simply this equation, but I got stuck. h/(4-sqrt(16+h)) = y First, I multiplied (4+sqrt(16+h)/(4+sqrt(16+h) to both sides, and I ended up with h(4+sqrt(16+h)/-h. Is this correct? (I tried to graph both equations to see
Can someone check these for me? Please? Use half-angle identity to find the exact value of cos165 degrees. (-1/2) sqrt(2+sqrt(3)) Write the equation 2x+3y-5=0 in normal form. (-2sqrt(13)/13)x- (3sqrt(13)/13)y+ (5 sqrt (13)/13) = 0
