For every cubic yard, it equals to 27 cubic feet.
So, could have this fraction
And we want to convert 3 cubic yards into cubic feet.
We can express 3 cubic yards as
Now multiply the
fraction by the second fraction or the reciprocal of the second fraction to cancel out the yards^3 units.
So, 3 cubic yards to equal to 81 cubic feet.
Answer:
Step-by-step explanation:
From the question we are told that:
Angle 
Height of plane 
Generally the trigonometric equation for distance flown d is mathematically given by
Therefore
Answer:
y=25.5
Step-by-step explanation:
To find y, you need to get it by itself. Ask yourself, what is being done to y, then to undo that, do the opposite. For example, if 3 was added to y, you would need to subtract 3 to cancel out the 3. In this case, what is being done to y? It's being divided by 3. So, you multiply by 3 to cancel that out. Whatever you do to one side of an equation, you also have to do to the other. So,
8.5=
Multiply both sides by 3
3(8.5) = 3() multiply on the left side, and on the right side the 3s cancel out
25.5=y
2x2+5x=12, 2x+5x=7x, 12+2=14, 7x/7=14/7, x=2
Vertex form is
y=a(x-h)^2+k
vertex is (h,k)
axis of symmetry is x=4, therfor h=4
y=a(x-4)^2+k
we have some points
(3,-2) and (6,-26)
input and solve for a and k
(3,-2)
-2=a(3-4)^2+k
-2=a(-1)^2+k
-2=a(1)+k
-2=a+k
(6,-26)
-26=a(6-4)^2+k
-26=a(2)^2+k
-26=a(4)+k
-26=4a+k
we have
-2=a+k
-26=4a+k
multiply first equation by -1 and add to second
2=-a-k
<u>-26=4a+k +</u>
-24=3a+0k
-24=3a
divide both sides by 3
-8=a
-2=a+k
-2=-8+k
add 8 to both sides
6=k
the equation is
