Aball is released at a height of 16 inches to roll inside a half-cylinder. it rolls to a height of 8 inches on the other side of the cylinder on roll 1. each time it rolls up a side of the cylinder, the ball reaches a point that is as high as it had reached on the other side. this explicit formula models the height of the ball, in inches, the nth time it rolls up a side of the cylinder. how high does the ball roll on its 5th time up the cylinder's side?

You and a friend race across a field to a fence and back. your friend has a 50-meter head start. the equations shown represent you and your friend's distances dd (in meters) from the fence tt seconds after the race begins. find the time at which you catch up to your friend. you: d=∣−5t+100∣d=∣−5t+100∣ your friend: d=∣−313t+50∣∣

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test
