On Mars, gravity is less than it is on Earth. If you were to kick a Mars rock at an initial velocity of 56 feet per second from
the top of 30-foot hill
, the rock's heighth would be modeled
by the equation h= -1.91 + 56+ + 30 wheret is time in
seconds.
How high would the rock be after 20 seconds

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
