For the factoring part for the 1st
y= a • b • c So make a diamond problem and in the top you will put the product of a • c and in the bottom it will be B then the two side values will multiply to the top value and add to the bottom value then make a generic rectangle in the left bottom you will put the first value in the original equation and the last value of the original equation in the top right and then fill the rest of the box in with the two side values from the diamond problem and find the dimensions and that’s your factoring equation
I will help up you using these statements which I took for the same problem:
a) at the lowest position of the bob, the KE is equal to zero.
FALSE BECAUSE AT THE LOWEST POSITION THE PE IS THE LOWEST AND THE KE IS THE HIGHEST.
b) at the highest position of the bob, the PE is equal to zero.
FALSE BECAUSE AT THE HIGHEST POSITION THE PE IS THE HIGHEST
c) at the highest position of the bob, the KE is equal to zero.
TRUE: AT THE HIGHEST POSITION THE PENDULUM COMES TO ZERO SPEED AND SO THE KE IS ZERO.
d) at all the positions except the highest positions the PE is zero.
FALSE: THE PE ENERGY CHANGES WITH THE ALTITUDE AND IS ZERO ONLY AT THE BASE LEVEL.
The answer to the question is 3.46
