A water balloon is dropped from the top of a building 64 feet above the ground. The equation
h(t) = -16t2 + 64 can be used to model the descent of the water balloon.
a. What are the x-intercepts of the function?

b. Interpret the meaning of the x-intercepts in context of the situation

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (x)

Will gve pints stars and brainliest

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
