Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Question
Transcribed Image Text:Solve the following rate of change problems (SOLVE a and b)
a) A man starts walking north at 4 ft / s from point P. Five minutes later, a woman starts walking
south 5 ft / s from a point 500 ft east of P, for what reason are separated from each other 5
minutes after the woman started walking?
b) The area of a trapezoid increases with a speed of 5 m² / min, its smaller base decreases
1 m2 / min and its greater base increases 1 m /s which speed changes its height when its
area is 1240 m², and its bases are 200m and 147m respectively
