Answer:  

y = 4x² -19x -5

Step-by-step explanation:  

When you graph it (or use an appropriate tool), it can help us to figure out that the equation is:

y = 4x² -19x -5

(Quadratic regression = the process of determining the equation of a parabola that best fits a set of data)

b)8x+24
c)2x^4+24
d)4x^2+24x+35
</span>

dimensions of the photograph 
length - 7 inch 
width - 5 inch
dimensions of the photo frame is 2x larger than both width and length 
length - 7 + 2x
width - 5 + 2x
the perimeter is sum of all 4 sides 
Perimeter = 2(7 + 2x) + 2(5 + 2x)
                 = 14 + 4x + 10 +4x
                 = 24 + 8x

The moon takes 28 days to orbit around the earth going at a distance of 2,413,000. How many kilometers does it take for the moon
Mazyrski [523]

Answer:

As per the statement;

The moon takes 28 days to orbit around the earth going at a distance of 2,413,000 km

From the above information,

The ratio between Distance and Days is; \frac{2413000}{28}

then,

the distance it takes for the moon to travel one day of its orbit around the earth we have;

\frac{2413000}{28} \times 1 = \frac{2413000}{28}=86178.57 km.

Therefore, the distance in kilometer does the moon cover in 1 day is 86178.57 km
