Given:
The monthly salary of salesperson is
The salary for new job is
Calculation:
From given, it is observed that
Here, the linear equation is,
Compute the linear equation for your current monthly wage
Hence, the linear equation for your current monthly wage
b)
To write:
The linear equation for your current monthly wage

Answer to Problem 1PS
Solution:
Explanation of Solution
Calculation:
From given, it is observed that
Here, the linear equation is,
Compute the linear equation for your current monthly wage
Hence, the linear equation for your current monthly wage
c)
To sketch:
The graph of the two equations

Answer to Problem 1PS
Solution:
The point of intersection is
Both jobs gives the same monthly salary when the sales is equals to
Explanation of Solution
Calculation:
From part (a) and (b), the two equations are
Draw the graph of the two equations
From the above graph, it is observed that the point of intersection is
Therefore, both jobs gives the same monthly salary when the sales is equals to
d)
To find:
The salary when the sales is

Answer to Problem 1PS
Solution:
No, the salesman doesn’t change the job because current job pays $3400 per month but new job pays $3300 per month.
Explanation of Solution
Calculation:
Compute the current job salary when the sales is
Therefore, the current job salary is $3400 when the sales is
Compute the new job salary when the sales is
Therefore, the new job salary is $3300 when the sales is
Hence, the salesman doesn’t change the job because current job pays $3400 per month but new job pays $3300 per month.

Assume that the air resistance FD acting on the body is proportional to the velocity V, so that FD=kV. Taking g = 9.75 m/s2 and k/m = 5 s, determine: a) what height the body will reach at the top of the tower, b) how long it will take the body to touch the ground, and c) the velocity of the body when it touches the ground.arrow_forwardA chemical reaction involving the interaction of two substances A and B to form a new compound X is called a second order reaction. In such cases it is observed that the rate of reaction (or the rate at which the new compound is formed) is proportional to the product of the remaining amounts of the two original substances. If a molecule of A and a molecule of B combine to form a molecule of X (i.e., the reaction equation is A + B ⮕ X), then the differential equation describing this specific reaction can be expressed as: dx/dt = k(a-x)(b-x) where k is a positive constant, a and b are the initial concentrations of the reactants A and B, respectively, and x(t) is the concentration of the new compound at any time t. Assuming that no amount of compound X is present at the start, obtain a relationship for x(t). What happens when t ⮕∞?arrow_forwardConsider a body of mass m dropped from rest at t = 0. The body falls under the influence of gravity, and the air resistance FD opposing the motion is assumed to be proportional to the square of the velocity, so that FD = kV2. Call x the vertical distance and take the positive direction of the x-axis downward, with origin at the initial position of the body. Obtain relationships for the velocity and position of the body as a function of time t.arrow_forwardarrow_back_iosSEE MORE QUESTIONSarrow_forward_ios
