Hello:) anyone able to explain and solve question 17 (aii) ? Thank you sm!

17 a(ii) : 4 -  2√3 and -4 +2√3.

Step-by-step explanation:

17 a (i).

(2 - √3)^2 = 4 - 4√3 + 3

= 7 - 4√3.

(ii) 28 - 16√3

= 4(7 - 4√3)

Now √4 = +/-2 and √7 - 4√3 =  2 - √3  ( as found in part (i)).

So the 2 square roots are 2(2 - √3)   and -2(2 - √3)

= 4 -  2√3 and -4 +2√3.

i dont understand the question? ?

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
