At tennis practice, Tim practices his backhand and his serve at least 2 hours each day. He works less on his backhand than his s

erve and practices his serve more than hour daily. What will the system of inequalities be that represents Tim’s daily tennis practice if x represents the number of hours spent practicing his backhand and y represents the number of hours practicing his serve?

Answer:

m = -2

Step-by-step explanation:

First lets fill in the variables

m = \frac{3-9}{2--1}

Now solve

3 - 9 = -6

2 - -1 = 3

-6/3 = -2

Anna007 [38]

Answer:

v=\pm48

Step-by-step explanation:

We have been given that you hit a ball from 4 ft above the ground with an initial vertical velocity of v ft/s. The function h=-16t^2+vt +4 models the height h in feet of the ball at time t in seconds.

First of all, we will find the time, when height will be maximum. We know that vertex is the maximum point for a downward opening parabola.

t=-\frac{b}{2a}=-\frac{v}{2(-16)}=\frac{v}{32}

To find the initial velocity for which the ball reaches a maximum height of 40 ft, we will substitute height (h) equal to 40 and t is equal to v/32 to  solve for v as:

40=-16(\frac{v}{32} )^2+v\cdot\frac{v}{32} +4

-16\frac{v^2}{1024}+\frac{v^2}{32}+4=40

-\frac{v^2}{64}+\frac{v^2}{32}-36=0

-\frac{v^2}{64}\cdot 64+\frac{v^2}{32}\cdot 64-36\cdot 64=0

-v^2+2v^2-2304=0

v^2-2304+2304=0+2304

v^2=2304

v=\pm\sqrt{2304}

v=\pm48

Therefore, the initial velocity would be \pm48.
