Michelle learns in science class that simple machines such as an inclined plane can change the amount of force needed to lift heavy objects. she decides to test this with an experiment. michelle chooses a 10 kg weight. she sets up a ramp made of smooth metal that makes an angle θ with the floor. she attaches a spring scale to the weight and the top of the ramp in order to hold the weight in place. she records the force from the spring scale, then changes θ and records it again. she repeats this several times. in this experiment, what is the outcome variable (dependent variable)? a. the amount of force on the spring scale b. the angle θ between the ramp and the ground c. the material the ramp is made of d. the mass of the weight reset submit

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
