A stone is tossed into the air from ground level with an initial velocity of 39 m/s. Its height at time is ℎ()=39−4.92 m. Compute the stone's average velocity ¯ in m/s over the time intervals [1,1.01], [1,1.001], [1,1.0001] and [0.9999,1], [0.999,1], [0.99,1].

(Use decimal notation. Give your answers to three decimal places.)

1) [0.9999,1]= m/s

2) [0.999,1]= m/s

3) [0.99,1]= m/s

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.

Plz hurry evaluate the expression a+b where a=8 and b=19

Taylor wants to paint his rectangular deck that is 41 feet long and 24 feet wide. a gallon of paint covers about 350 square feet. how many gallons of paint will taylor need to cover the entire deck? round your answers to two decimal places when necessary.
