TO get 6% of 20 we have to write 6% in decimal (or fraction if u want but decimal allows u to multiply it easier i think)
6%=0.06=
Now u have to mulitply 0.06 times 20
0.06*20=1.2 - its the result
Given:
The given equation is:
Where, t is the time in seconds and h is the height of the ball above the ground, measured in feet.
To find:
The inequality to model when the height of the ball is at least 36 feet above the ground. Then find time taken by ball to reach at or above 36 feet.
Solution:
We have,
The height of the ball is at least 36 feet above the ground. It means 
.
Splitting the middle term, we get
The critical points are:
These two points divide the number line in 3 intervals 
.
Intervals Check point Result
0 
False
4 
True
8 
False
The inequality is true for (2,6) and the sign of inequality is 
. So, the ball is above 36 feet between 2 to 6 seconds.
Therefore, the required inequality is and the ball is 36 feet above for 4 seconds.
Answer:
The first one
Step-by-step explanation:
The first one because the largest exponent is odd and its coefficent is positive
Answer:
x=9 and z=83
Step-by-step explanation:
First you subtract 97 from 180 because that gives you z because 180 is a flat angle and 83 plus 97 gives 180. For x the opposite angle is also 97 so you set the equation 5x + 52 = 180 and you solve for x to get the x value. Hope this helps :)
