Answer:
The surface area is 
Step-by-step explanation:
The surface area of a rectangular prism is calculated using the formula;
![S.A=2[lw+lh+wh]](https://tex.z-dn.net/?f=S.A%3D2%5Blw%2Blh%2Bwh%5D)
The length of the rectangular prism is
The height is 
The width is 
The surface area
![S.A=2[10(8)+10(6)+8(6)]](https://tex.z-dn.net/?f=S.A%3D2%5B10%288%29%2B10%286%29%2B8%286%29%5D)
![S.A=2[80+60+48]](https://tex.z-dn.net/?f=S.A%3D2%5B80%2B60%2B48%5D)


<u>Answer:</u>
Height of cables = 23.75 meters
<u>Step-by-step explanation:</u>
We are given that the road is suspended from twin towers whose cables are parabolic in shape.
For this situation, imagine a graph where the x-axis represent the road surface and the point (0,0) represents the point that is on the road surface midway between the two towers.
Then draw a parabola having vertex at (0,0) and curving upwards on either side of the vertex at a distance of
or
, and y at 95.
We know that the equation of a parabola is in the form
and here it passes through the point
.




So new equation for parabola would be
.
Now we have to find the height
of the cable when
.

y = 23.75 meters
So let T be the max and min temperature, and let x be the given temperature in °F.
T = x+-12
So for this case the Tmax will be 40°F using the equation above.
And Tmin being 16°F
Hi again!
The zeros are the values of x. This is where the graph intersects the x - axis. In order to find the zeros, replace y with 0 and solve for x.
The answer is x = 0, -π, 4I am not sure what grade are you or the level, but for me, they sometimes asked me to find their multiplicities as well
The multiplicity of a root is the number of times the root appears.
So, the answer are
x = 0 and the multiplicity of 2
x = -π and the multiplicity of 3
x = 4 and the multiplicity of 2
Good luck with your studies!
17.9/2.38
= 7.5.
Hope this helps & good luck. :)
