Mr. mole left his burrow and started digging his way down.

b(t) models mr. mole's depth relative to the ground (in meters) after t minutes.

how far below the ground is mr. mole after 5 minutes?

b(t) = -2.3t - 7

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
