A ball is thrown vertically upward from the ground with an initial velocity of 111 ft/sec. Use the quadratic function h(t) = −16

ddd [48]

Answer:

t=3.5 seconds

Step-by-step explanation:

Given

h(t) = −16t^2 + 111t + 0

h'(t)= -32t + 111

Maximum height occurs when h(t) = 0 and the ball begins to fall

h(t)= -32t + 111=0

-32t + 111=0

-32t=-111

Divide both sides by -32

t=3.46872

Approximately, t=3.5 seconds

Recall,

Maximum height occurs when h(t) = 0

h(t)= -32t + 111=0

= -32(3.46872)+111

= -110.99904+111

= 0.00096 ft

A copper key is placed in a cylindrical container with a 3-cm diameter. The water level rises from 14 cm to 14.6 cm. What is the

Tomtit [17]

Answer:

The volume is about 4.24 cm^3.

Step-by-step explanation:

From the question we are told that:

Diameter $d= 3-cm$

Radius $r=d/2=>1.5cm$

Height risen $14.6-14=0.6cm$

Generally the equation for Volume of a Key is mathematically given by

Since Volume of a cylinder is Given as

$V=\pir^2h$

Therefore

$V=\pi*1.5^2*0.6$

$V=4.2417\\\\V=4.24 cm^3$

Correct Option A

The volume is about 4.24 cm^3.
