Answer:
Step-by-step explanation:
XY = 15 MI.
YZ = 8 mi.
Area = A
A = 1/2 (XY)(YZ)
A = 1/2 (15)(8)
A = 1/2 (120)
A = 60
Answer:
20 * 19.52 = 390.40

Answer:
T = 1.5s
Step-by-step explanation:
Hello,
To find the time the pincone hits the ground, we need to use the equation given.
Note that h = 0 when the pinecones hits the ground.
This question relates to motion under gravity.
h = -16t² + 36
0 = -16t² + 36
Make t² the subject of formula
16t² = 36
t² = 36 / 16
t² = 2.25
Take the square root of both sides
t = √(2.25)
t = 1.5s
The time it takes the pinecone to hit the ground is 1.5s.
