2. A projectile is launched upward from a platform 10 meters high with an initial velocity of 40 meters per second. The height of the projectile (h) in meters after t seconds is given by the equation: h(t) = -4.9t^2 + 40t + 10.
a. What is the maximum height reached by the projectile and when does it reach this height?
b. When will the projectile hit the ground?
c. Create a sketch of the projectile's height over time on a coordinate plane. Label the axes and key points (initial height, maximum height, time to hit ground).
3. A company's monthly sales (in thousands of dollars) for the past six months were: 150, 165, 155, 170, 180, 160. Calculate the following measures of central tendency and dispersion.
a. Mean:
b. Median:
c. Mode:
d. Range:
e. Standard Deviation (round to two decimal places):
4. A cylindrical water tank has a radius of 3 meters and a height of 10 meters.
a. Calculate the volume of the tank. (Use π ≈ 3.14)
b. Calculate the lateral surface area of the tank. (Use π ≈ 3.14)
