Answer the following questions. write units wherever appropriate. a. a spring with spring constant 12 pounds per foot is attached to the ceiling. a 4 pound weight is attached. how far does the spring stretch? the mass-spring system is then set in motion in a medium that imparts a damping force numerically equal to 2 times the velocity. the mass is pushed up three inches from the equilibrium position and given a downward velocity of 2 feet per second. write down the initial value problem for the position, x (t). now solve the initial value problem given above.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
