Answer:
Step-by-step explanation:
Given that Elijah threw a ball from a height of 4 feet. The ball reached maximum height of 16 feet after 2seconds
Let vertical component of his speed be v
When it reaches maximum height its velocity becomes 0
Hence
height reached by the ball =
When h=12(16-4) we get g=gravity =32
Hence 12 =2v-16(4)
v=38
Hence 
where h is calculated from the height of hand i.e. 4 feet
When it touches the ground h =-4
When it starts falling then distance travelled = 16 feet
Initial velocity =0 Accn due to gracity =32 feet
Using these we can write

So after 3 minutes from start the ball would reach the ground
Answer:
A. 1
Step-by-step explanation: You have to substitute the numbers in for x
A. 1:
-5x -1 < -9
-5(1) - 1 < -9
-5 - 1 < -9
-6 < -9
B. 2:
-5x - 1 < -9
-5(2) - 1 < -9
-10 - 1 < -9
-11 < -9
C. 3:
-5x - 1 < -9
-5(3) - 1 < - 9
-15 - 1 < -9
-16 < -9
D. 4:
-5x - 1 < -9
-5(4) - 1 < -9
-20 - 1 < -9
-21 < -9
- Remember, a negative plus another negative is a negative
Hope this helps you!!! :)

Answer:
The necklace will be 4,000 cm long
Step-by-step explanation:
Here we want to calculate the length of the necklace
Mathematically, that would just be the product of the beads and the diameter of each bead
Hence, we have
10,000 * 0.4 = 4,000 cm
