Here’s the repostttt
Aleksandr-060686 [28]

1. we have to find what number lie at A and B , and that too between and 1 and 2 , so these two numbers must be decimal numbers!! So let's find the number of scales between 1 and 2 , we get 8 scales !! So the question is how much place 1 scale will occupy ?? we have to find certain numbers between 1 and 2 , suppose between 1 and 2 we have 1 unit and those 1 unit occupies 8 scales !! so much place 1 scale occupies ?? to get it divide 1 by 8 and we get 0.125 !! so between 1 and 2 ,each blank space or scale occupies 0.125 unit!! now what numbers lie at A ? count the number of scale between 1 and A , we get 3 scales ! now multiply 3 by 0.125 , we get 0.375 , add 1 to 0.375 , we get 1.375 !! hence 1.375 lies at A ! now we have to find which number lies at B ? count the number of blanks or scale , we get 4 ! multiply 4 by 0.125 and we get 0.5 ! add this 0.5 to 1 , we get 1.5 ! therefore the number 1.5 lies at B !!

2. for 2nd number solution refer to the attachment! !

Evaluate dydx at x=2 for the function below.<br><br> y=6u^3+5u+2, where u=−3x^2−4x+9
bekas [8.4K]

Step-by-step explanation:

y = 6u {}^{3}  + 5u + 2

y = 6( - 3 {x}^{2}  - 4x + 9) {}^{3}  + 5( - 3 {x}^{2}  - 4x + 9) + 2

Use the chain rule.

\frac{dy}{dx}  = 6(3)( - 3 {x}^{2}  - 4x + 9) {}^{2} ( - 6x  -  4) + 5( - 6x - 4)

18( - 3 {x}^{2}  - 4x + 9) {}^{2} ( - 6x - 4) + 5( - 6x - 4)

Factor out -6x-4,

( - 6x - 4)(18( - 3 {x}^{2}  - 4x + 9) {}^{2}  + 5)

Know plug in x=-2 to evaluate the derivative

( - 6(2) - 4)(18( - 3(2) {}^{2}  - 4(2) + 9) {}^{2}  + 5)

( - 16)(18(( - 12) - 8 + 9)) {}^{2}  + 5)

- 16(18( - 11) {}^{2}  + 5)

- 16(2183)

- 34928
