We have been given that the quadratic equation models the path of a heavy ball through the air, where y represents the height in feet and x represents time in seconds. We are asked to find the time when ball will hit the ground.
The ball will hit the ground, when height of ball above ground will be 0. So we will equate our given quadratic equation with 0 and solve for x.
We will use quadratic formula to solve our given problem.
, where
b = Coefficient of x term,
a = Coefficient of term,
c = Constant.
Since time cannot be negative, therefore, the ball will hit the ground after 10 seconds.
B. X= -7; Y= 5
C. X= -5; Y= -7
D. X= 5; Y= 7
complete question:
$0.60 bottle of iced tea marked up to $1.35. Find the percentage markup.
Answer:
percentage markup = 125%
Step-by-step explanation:
$0.60 bottle of iced tea marked up to $1.35. The marked up percentage can be calculated as follows:
1.35/0.60 = p/100
2.25 = p/100
2.25 = p/100
multiply both sides by 100
2.25 × 100 = p
225%
Therefore the mark up is 225 - 100 = 125%
percentage markup = 125%
Hello!
First, let's analyze these two quadrilaterals:
• Notice that the quadrilateral AB'C'D is ,smaller ,than the quadrilateral ABCD.
Let's try to solve it using the lines AB and AB':
