Well the position function is:
h(t)=-16t^2+256
It will hit the ground when h(t)=0
-16t^2+256=0 factor out -16
-16(t^2-16)=0 factor difference of squares...
-16(t+4)(t-4)=0, since t>0
t=4 seconds
Answer: The Distributive Property is easy to remember, if you recall that "multiplication distributes over addition". Formally, they write this property as "a(b + c) = ab + ac". In numbers, this means, for example, that 2(3 + 4) = 2×3 + 2×4.
Answer:
-5
Step-by-step explanation:
y intercept occurs when x = 0
f(0) = -4(0)² + 2(0) - 5
f(0) = - 5
Step-by-step explanation:
First, multiply each side of the equation by
2
to eliminate the fraction while keeping the equation balanced:
2×A=2×h2(a+b)
2A=2×h2(a+b)
2A=h(a+b)
Now, divide each side of the equation by
a
+
b
to solve for
h
while keeping the equation balanced:
2Aa+b=h(a+b)a+b
2Aa+b=h(a+b)a+b
2Aa+b=h
h=2Aa+b
Answer:
Domain { 4,8,12,16,20}
Range { 1,2,3,4}
This is not a function because two of the inputs have more than one output
Step-by-step explanation:
The domain is the x values ( input)
Domain { 4,8,12,16,20}
The range is the y values (output)
Range { 1,2,3,4}
This is not a function because two of the inputs have more than one output
