Best ResponseYou've already chosen the best response.0no the derivative of that is 4

Best ResponseYou've already chosen the best response.2yes thats right so the slope is  at every point on the graph as its a straight line

Best ResponseYou've already chosen the best response.2so to find the slope at (16,4) plug x = 16 into the the above value for f'(x)

Best ResponseYou've already chosen the best response.2then use the general form yy1 = m(xx1) and plug in slope m and the point (x1,y1) will be (16,4)

Best ResponseYou've already chosen the best response.21 / 2*x(1/2) = 1 / 2* (16)^1/2 = 1/ 2*4 = 1/8

Best ResponseYou've already chosen the best response.2m stands for the slope in the formula the slope is given by the derivative of sqrt x  and is 1 / 2* x (1/2) o r 1 / 2 sqrtx here x = 16 ( point is (16/4) so m = 1 / 2 sqrt16 = 1 / 2*4 = 1/8

Best ResponseYou've already chosen the best response.1first of all the slope of a tangent line is the gradient of that line ok

LynFran

Best ResponseYou've already chosen the best response.1now to find the slope of the tangent line is y/x...dw:1435279410553:dw

Best ResponseYou've already chosen the best response.14 is just the slope of the tangent line we have to find the slope intercept equation at the given point ok to complete this question ok

Best ResponseYou've already chosen the best response.1now to take the derivative of it we getdw:1435281258598:dw

Best ResponseYou've already chosen the best response.0ok im with you, so whats next

LynFran

Best ResponseYou've already chosen the best response.1well we have to plug in the value of x into the derivative we just found

LynFran

Best ResponseYou've already chosen the best response.1(16,4) and x=16 there ok so.. plug it into the derivative and let me know what u get

anonymous

Best ResponseYou've already chosen the best response.0ok so when i plug in 16 and solve to find the derivative i get 0

LynFran

Best ResponseYou've already chosen the best response.1no u cant get 0 lets work it together

Best ResponseYou've already chosen the best response.1so 1/8 is this part Find the slope of the tangent line to the graph of f at the given point.

Best ResponseYou've already chosen the best response.1so can u find this part now .Find the slopeintercept equation of the tangent line to the graph of f at the given point. dw:1435282844490:dw

Best ResponseYou've already chosen the best response.1correct now the next step is to multiply out the bracket

LynFran

Best ResponseYou've already chosen the best response.1good next step is to bring the 4 over the equal sign ...remember when we bring a # over the equal sign , the sign of the # changes
