The changing speed of a car is modeled by the function s(t) = −35t + 30, where t is time in seconds. interpret the model
a. the car has an initial speed of 0 units and is speeding up to a speed of 30 units by 35 units per second.
b. the car has an initial speed of 35 units and is speeding up by 30 units per second.
c. the car has an initial speed of 30 units and is slowing down by 35 units per second.
d. the car has an initial speed of 30 units and is speeding up by 35 units per second.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
