Adrianne is playing soccer, and kicks the ball at the goal. The ball follows the path of a quadratic function. When she kicks the ball, she is 20 feet away from the goal, and the ball hits a maximum height of 10 feet when it is 5 feet away from the goal line. If the net is 8 feet tall, does she make a goal (assuming the goalie does not stop the ball)? a. Draw a diagram of the situation, including known values.

Tactile acuity refers to the minimum separation required between two points for the brain to perceive them as two separate points.

When comparing the tactile acuity of various body parts, what have you concluded about the number of receptors in the palm of your hand relative to the number of receptors on your shoulder?

Select one:

a. The tactile acuity for the palm is larger than for the shoulders. Therefore, more receptors are found on the palm than on the shoulders.

b. The tactile acuity for the palm is larger than for the shoulders. Therefore, more receptors are found on the shoulders than on the palm.

c. The tactile acuity for the shoulders is larger than for the palm. Therefore, more receptors are found on the palm than on the shoulders.

d. The tactile acuity for the shoulders is larger than for the palm. Therefore, more receptors are found on the shoulders than on the palm.
