The cost c (in dollars) of making n watches is represented by c=15n+85. how many watches are made when the cost is $385

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases

What are the sotions to the quadratic equation 9x^2=4

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.
