Giovanni drops a rock from the Leaning Tower of Pisa in Italy. The height in feet (h) of the falling rock above the ground is
given by the following equation, where t represents the time, in seconds.
h = -16t2 + 186
Approximately how long will it take the rock to reach the ground?
Answers
It would take about 3.4 seconds for the rocks to reach the ground.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let h represent the height of the rock above the ground after t seconds. Given the equation:
h = -16t² + 186
The rock would reach the ground at h = 0, hence:
0 = -16t² + 186
16t² = 186
t = 3.4 seconds
It would take about 3.4 seconds for the rocks to reach the ground.

Then find the area of the half circle, the formula of the area of a circle is [tex]\pi r^2[/tex]
here it's half a circle so it's [tex]\frac{\pi r^2}{2}[/tex] where r is 12
-> [tex]3.14\cdot \frac{\left(12\right)^2}{2}=226.08 m[/tex]

Answer:
The Scale Factor is 5.3
Step-by-step explanation:
Here's the reason why:
You are trying to make the rectangle much larger.
The 14yd by 6yd is trying to get to the 74.2yd by 31.8yd.
We need to remember the importance of length and width.
If 14 yards is our length then 74.2 yards is our length on the enlarged rectangle.
You must do 74.2/14 because we need to work backwords.
**You can't find something to multiply 14 by to get to 74.2 unless you do division.**
74.2/14 is 5.3
Now do the same with the width.
31.8/6
That is 5.3 as well.
Therefore the scale factor is 5.3

Step-by-step explanation:
Try to line up percents % and the actual numbers they represent.
number : precent
60 is 100%

cross multiply
x·60 = 100·18
divide both sides by 60 to isolate x
x = ((100·18)/60
x = 30
