6. The height of a baseball thrown into the air can be represented by the following equation:
h(t) = -4.9t2 + 210 + 2 , where h(t) is the height of the ball in meters after t seconds.
a. Find h(t) when t = 0 and give the real-world meaning for this value.
b. When will the ball hit the ground? SHOW YOUR WORK
c. How many seconds does it take the ball to reach 20 meters above the ground? SHOW YOUR
WORK

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
