Refer to the previous page (4) to answer this question. Once this program has completed. Indicate where the robot will be located by selecting the correct choice below. Circle the letter to the left of the selection to indicate your answer upper left corner upper right corner center top of grid center bottom of grid off the left side of the grid off the right side of the grid while it is not a good idea to write complicated formulae in programming, someone sneaked in and wrote the following expression when the examination author wasn\'t looking x = (-b + sqrt(b^2 - 4*a*c))/2* a; From the following, select the most correct statement about the expression shown. Circle the letter to the left of the selection to indicate your answer the first operation that will be conducted Is the b^2 - 4 * a * c operation will be calculated within the parentheses the first operation that will be conducted is the -b + sqrt operation will be calculated within the parentheses the first operation that will be conducted Is the 4 * a * c operation the first operation that will be conducted is the b^2 operation all of the above statements are correct none of the above statements is correct From the following, select the most correct statement about the expression shown Crete the letter to the left of the selection to indicate your answer. for purposes of Matlab operations, this expression is a fully correct for purpose of Matlab operations, this expression has a mistake in the numerator for purpose of Matlab operation, this experiment has a mistake in the denominator for purposes of Matlab operations, this expression has a mistake in both the numerator and denominator all of the above statements are correct none of the above statements is correct

Solution

7)
Ans a)for purpose of matlab operation , this expression is fully correct.

example: % This m-file will solve the quadratic equation :ax^2 + bx + c = 0

function Quad= Quadratic(A,B,C)

% A=1;
% B=2;
% C=3;

%If-Else statement for if A=0

if A==0,
X= -C/B;
else
X(1) = (-B+sqrt(B^2-4*A*C))/(2*A);
X(2) = (-B-sqrt(B^2-4*A*C))/(2*A);

disp(X(1))
disp(X(2))
fprintf(\'X(1) = %f \ \',X(1));
fprintf(\'X(2) = %f \ \',X(2));
  

end

  

6)
Ans a)the first operation that will be conducted is b^2 operation

Explanation:Because the operator () has higher precedence and ^ operator is inside () .so first operation will be b^2.
