Answer:
-8p + 7
n = --------------
8 - 5p
Step-by-step explanation:
Let's group the n terms in 5pn-8p=7n-7 .
Subtract 5pn from both sides. This results in -8p = 7n - 7 - 5pn
Now add 7 to both sides. This will group the n terms on the right side:
-8p + 7 = 7n - 5pn
Factor n out of 7n - 5pn:
-8p + 7 = n(7 - 5p)
Finally, divide both sides by (7 - 5n) to isolate n:
-8p + 7
n = --------------
8 - 5p
Let
be a rectangular
matrix with column vectors
, i.e.
Then we have
and the product of the two is
Because the columns of
are orthonormal, we have
which means
reduces to an
matrix with ones along the diagonal and zero everywhere else, i.e.
where
denotes the identity matrix. This means the solution to
is given by
For this case, the sales space of the displays is given by:
(2400) * (1-0.60) = 960 feet ^ 2
We now look for the area of each display:
(10) * (4) = 40 feet ^ 2
With this information, we can then search the number of displays:
N = (960) / (40)
N = 24 displays
Answer:
you can fit 24 displays.
D. Y is negative and x is positive, so that means either B or D. Since y is negative, SUBTRACTING five would make a more negative number. So you want D.
Answer: Rectangle around the cylinder, Lateral surface of the cone, Half a sphere
To find this surface area, you have 3 different parts. First, you need the rectangular portion of the cylinder, because the circles will be on the inside of the composite shape. Then, you will need the lateral side of the cone, that's everything but the circular base. Again, the circle will be on the interior. Finally, you should find the surface area of half of the sphere.
