I believe only two but im not really sure on that
Answer:
It is 79,900, Since 10^4 is 10000.
Step-by-step explanation:
Answer: t= 4 seconds
Maximum height = 256 feet
Step-by-step explanation:
The height of the object projected upwards after t seconds is given by
s(t)=-16t^2+128t.
The expression is a quadratic equation. When this equation is plotted on a graph, height against time, it takes the shape of a parabola whose vertex represents the maximum height attained by the object.
To get the value of t at the maximum height,
t = -b/2a
From the equation,
a = -16
b = 128
t = -128/-2×-16
= -128 /- 32= 4
it will take 4 seconds to reach its maximum height
To find maximum height attained, put t= 4 in the equation
s(t)=-16t^2+128t
S = -16× 4^2 + 128×4
S = -256+512
S = 256 feet
Step-by-step explanation:
To solve one step equations you have to do the opposite of whatever operation is being performed on the variable so you have to get the variable by itself
The most important thing to remember is that whatever you do to one side of the equation, you have to do the same thing to the other side.
