V=w•h•l
w=2 1/2=5/2=2.5 m
h=1 3/4=7/4=1.75 m
l= 2 1/4=9/4=2.25 m
V= 2.5 •1.75 •2.25
V=9.84 m^3
Answer:
Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
Just by looking at the way the graph is pointing you can eliminate answer choices B and C because the set up of this equation will be x = not y =
So the set up of the equation is
x=2(y-(the y value of the vertex)squared+(the x value of the vertex)
by using this you can eliminate option D and see that the answer is A
Let
x-------> the time
y-------> the altitude of a helicopter
Step 1
<u>Find the slope of the line</u>
we know that
the slope m of the line between two points is equal to
we have
substitute in the formula
therefore
<u>the answer is the option </u>
The slope is . This means that the helicopter descends ft each minute.
