What grade do you take physics in? what are all the classes you have to take in high school? (18 pts)

The grade of 6th and 7th. ans there are 8 classes in high school

I am pretty sure there are 8 classes in high school and you take physics in 6th and 7th grade

hope this helped

You need to figure out at which x-value does the graph has a tangent line slope of -1.remember, the derivative is the slope of the tangent line. so find the derivative function and set it to equal -1 to find the x-value that will have a tangent line slope of 0.differentiate with the chain rule.    set the derivative to equal -1 and solve for x.      take log base 10 of both sides. also recall that  .    so the x-coord of the point of tangency is .the y-coordinate of this point of tangency can be calculated using the original function:     using point-slope form, the equation of the tangent line is      the x-intercept of this tangent line is when the graph is at y=0.    this rounds off to  .choice c.

Sorry this isn’t really an answer i just need to answer two questions. i hope that you find the answer that your looking for though
