15. the velocity of an object fired directly upward is given by v = 20 – 9.8t, where t is time in seconds. write an inequality which could be used to describe when the velocity will be between 10 and 20 meters per second. (see ex. 8) explain to verify your choice. 10 > 20 – 9.8t > 20 10 > 20 – 9.8t or 20 – 9.8t < 20 10 < 20 – 9.8t or 20 – 9.8t < 20 10 < 20 – 9.8t < 20

Step-by-step explanation:

we are given

The velocity of an object fired directly upward is given by

where t is time in seconds

Since, velocity is velocity is between 10m/s and 20m/s

so, velocity is greater than 10 and less than 20

so, we can write our inequality as

now, we can plug v

and we get

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.
