Answer:
t = 2.5 s
Step-by-step explanation:
Suppose you have a water-balloon launcher. The balloon is 3 ft high when it leaves the launcher. Its equation is :
The above equation is a quadratic equation. The general equation is :
Here, a = 16, b = 38.8 and c = 3
The solution of quadratic equation is given by :
So, at t = 2.5 s the balloon is in air.
Slope = rise/run
Rise = 3, run = 8
Downwards line = negative
Slope = -3/8
Answer:
well to get that you add all them and divide
Step-by-step explanation:
56 because it is the distance of a number from zero! Hope that helped!
The standard form of ellipse with vertical major axis and center at the origin is:
x^2/b^2+y^2/a^2=1, a>b
2a=length of the major axis=28
a=14
a^2=196
2b=length of minor axis=20
b=10
b^2=100
x^2/196+y^2/100=1
making y the subject we get
y=5/7(196-x²)^0.5
