Input the coefficients of a,b and constant c of the second equation:
-3 = 5 = 2 =

Press the = to get the value of x and press again to get the value of y..

And you will get the answer..

5. The equation has two
rational roots, both of which are positive. Find the larger
of these two roots.
A. 1
B. 2
C. 3
D. 4

Code:

Same method with number 3..We will be using CALCU function..The

calculator should display 0..
And you will get the answer..

6. What is the remainder of the

polynomial when divided by
A. 208
B. 218
C. 283
D. 305

Code:

Set the calculator to computation mode: MODE>1
Input the left side of the equation
Apply the Remainder theorem
Use CALCU function and substitute x=5

And you will get the answer..

7. Solve the values of y in the system of equations:

Code:

Set the calculator to equation mode: MODE>5>2
Input the coefficients a,b and constant c of the first, second and third
equation..

Press the equal = button twice to get the value of y..
And you will get the answer..

8. Solve for the value of
A. 2
B. 2i
C. -2
D. -2i

Code:

Set the calculator to computation mode: MODE>1
Input the equation in the calculator(as is)..

and you will get the answer..

9. Solve for the value of
A. 1.91
B. 2.19
C. 1.19
D. 2.91

Code:

Set the calculator to computation mode
Input the equation in the calculator(as is)

Page 11

Dividing the results and you got the answer..

17. Find the equation of the nomal line of the

curve at (1,2)
A. 4x-y=2
B. 4x-y=-2
C. x+4y=9
D. x+4y=-9

Code:

When you are getting the slope of the line using the first derivative, what
you are getting is the slope of the tangent line..To get the slope of the
Normal Line, you get the negative reciprocal of this..
So, get the first derivate(Tangent slope) of the given equation with
x=1(given in the problem)

And getting the negative reciprocal of this we have -1/4..
Then get the equation using STAT 2..

And press AC..Get A and B..
SHIFT>1>7> and SHIFT>1>7>2

Remember, in the calculator, the equation of STAT 2 is y=a+bx..

Substitute a and b in the equation and you will get the answer..

18. The charge in coulombs that passes through a wire
after t seconds is given by the

function.

Determine the current at the end of 2 seconds..
A. 6 A
B. 8 A
C. 9 A
D. 10 A

Code:

Simple get the first derivative of this with x=2 (2 seconds) and you will get

19. A 1800-gallon tank of water drains from the bottm in
30 min. According to Torricelli's law, the volume of water
remaining in the tant after t minutes is

where
How fast is the water draining from the tant after 20
minutes?
A. -40 gpm
B. -30 gpm
C. -20 gpm
D. -10 gpm

Code:

Simply get the derivative of the equation with x=20 (20 minutes)..
And you will get the answer in gpm..

20. Find the value of x when the function y=lnx/x is at
maximum value.
A. 0
B. e
C. 1
D. 1/e
