Commutative property of addition:
a + b = b + a
If we have : 2 + 5 = 5 + 2
it is B ) commutative property of addition.
Answer:
See below in bold.
Step-by-step explanation:
A). s(t)= -16t^2+64t+200
Converting to vertex form.
s(t) = -16 (t^2 - 4t) + 200
s(t) = -16 [(t - 2)^2 - 4] + 200
s(t) = -16(t - 2)^2 + 64 + 200
s(t) = -16(t - 2)^2 + 264
The maximum height is after 2 seconds and it is 264 feet.
B) The ball hits the ground when s(t) = 0 so we have:
-16t^2+64t+200 = 0
x [-64 +/- sqrt (64^2 - 4*-16*200) ] / -32
x = 6.06, -2.06
So the answer is 6.06 seconds.
Each coordinate is plotted in the graph below. The shape is a quadrilateral and has a pair of parallel lines. The shape is a trapezoid.
Product means to multiply. Integers are whole numbers, so the process would be to multiply the numbers.
