Great Galloping Galaxies in 4GB!

January24

The Hubble Space Telescope of ESA has captured the largest and sharpest image of the Andromeda galaxy that lies at a distance of 2.5 million light years. The image was first released at the meeting of 225th meeting of American Astronomical Society (AAS) in early January and is comprised of 1.5 billion pixels. It uses […]

Time and Space – Hubble exposes deep space

September27

A stunning new composite photograph from the Hubble Space Telescope, made up of more than 2,000 images shot by multiple cameras over the past 10 years and combined in what amounts to a 23-day time exposure, shows some 5,500 galaxies in tiny field of view, including some dating back to just 450 million years after […]

NCEA Level 2 Algebra Problem. Using the information given, the shaded area = 9, that is:
y(y-8) = 9 –> y.y – 8y – 9 =0
–> (y-9)(y+1) = 0, therefore y = 9 (can’t have a distance of – 1 for the other solution for y)
Using the top and bottom of the rectangle,
x = (y-8)(y+2) = (9-8)(9+2) = 11
but, the left side = (x-4) = 11-4 = 7, but rhs = y+? = 9+?, which is greater than the value of the opp. side??
[I think that the left had side was a mistake and should have read (x+4)?]
