An 8.5 m ladder whose weight is 310 N is placed against a smooth vertical wall. A person whose weight is 515 N stands on the ladder a distance 1.8 m up the ladder. The foot of the ladder rests on the floor 5.78 m from the wall. Calculate the normal force exerted by the floor o...
A 1480 kg automobile has a wheel base (the distance between the axles) of 2.9 m. The center of mass of the automobile is on the center line at a point 1.34 m from the front axle. Find the force exerted by the ground on each back wheel. The acceleration of gravity is 9.8 m/s2. ...
you can find it one of two ways. the first is using the calculator which is the easiest or you can do it by hand. calculator: solve for y for both equations and then plug the first equation as y1 and the second equation as y2. then you do 2nd calc intersection (5) on the calc ...
f(x)=x^3-(4/x) find [f^(-1)(x)]' at x=6
8 gallons per hour each gallon wt. 7 1/4 in six hours what is the amount in pounds?? and how did you arrive at this solution??
Note: The left-hand mass is equal to the sum of the other two masses. A massless pulley is attached to the ceiling,in a uniform gravitational field, and rotates with no friction about its pivot. Another massless pulley is attached to the end of the cord on the right and rotate...

y=3x^4 inverse: u switch the x and y: x=3y^4 now u solve for y: x/3=y^4 fourth root of x/3=y
pretend $1 is x and $5 is y x+8=y *bc you have to add 8 $1 to have the same number of $1 as $5 1x+5y=124 *this is basically saying that there is an "x" number of $1 bill plus a "y" number of $5 will get u $124 now use elimination: since y=x+8 plug "x+8...
this is similar to the question I answered on the question after this: pretend nickels=x dimes=y x+y=21 *total number of dimes and nickels is 21 .05x+.1y=$1.65 *the value of x is .5 and the value of y is .1 so when you multiply it by the number of x and y you get $1.65 now use...
