Residents of the town of Smithfield like to consume hams, but each ham requires 10 people to produce it and takes a month. If th

Snezhnost [94]

Answer:

A tenth of a ham.

Step-by-step explanation:

1 Ham requires 10 people to make it and takes 1 month.

the population of the town is 100, so the quantity of ham we can produce is given by:

$\frac{Total People}{people required} = \frac{100}{10} = 10$

Acording to the last result, we can produce 10 hams per month.

if the total of people is 100, and the hams produced was 10, each people can consume:

$\frac{hams}{people} = \frac{10}{100} = 0.1$

Suppose a football player kicks a ball and gives it an initial upward velocity of 47 ft/s. Use the formula h(t)= -16t^2+47t+3 wh

statuscvo [17]

Answer:

Step-by-step explanation:

a. when t=0,h=3ft

$h(t)=-16 (t^2-\frac{47}{16}x+(\frac{47}{32} )^2)+\frac{47^2}{32^2} *16+3\\=-16(t-\frac{47}{32})^2+\frac{2209}{64}+3\\=-16(t-\frac{47}{32})^2+\frac{2209+192}{64}\\when~ t=\frac{47}{32}\\h=\frac{2301}{64}\\or~v^2-u^2=2gh\\\\0^2-47^2=2*(-32)h\\or h=\frac{47^2}{64}=\frac{2209}{64} \\height from the ground=\frac{2209}{64} +3=\frac{2301}{64}$

c.t=47/32 sec

time taken to fall 2301/64 ft=0*t+\frac{1}{2}*32*t^2

t^2=\frac{2301}{64*16}

t=\frac{\sqrt{2301}}{8*4}=\frac {47.97}{32}

total ~time=\frac{47+47.97}{32}=\frac{94.97}{32} sec
