A T-ball player hits a ball from the tee that is 0.6m tall. The height of the ball at a given time is modelled by the function h(t)= -4.9t^2 + 7t + 0.6, where height, h(t), is in metres and time, t, is in seconds

What will the height be after 1 second?

Question

A T-ball player hits a ball from the tee that is 0.6m tall. The height of the ball at a given time is modelled by the function h(t)= -4.9t^2 + 7t + 0.6, where height, h(t), is in metres and time, t, is in seconds 

What will the height be after 1 second?

anonymous · Answer

where you see a $t$, put a $1$
i.e.compute $h(1)$

anonymous · Answer

computing with 1 is very easy
add up the coefficients

anonymous · Answer

you got that ?

anonymous · Answer

exactly

anonymous · Answer

the functions represents the height at time $t$ so in 1 second it is $h(1)$

alright, thank you!!

yw

anonymous · Answer

plug one into t and do the math its as easy as it sounds:) good luck:)

you can also use a calculator like desmos to graph and compute the value of `h(1)`

see the attached image
