When the curiosity mars rover landed on mars in august 2012, it sent a radio signal with the message, “it once was a small step … now it’s six big wheels.”
the distance between mars and earth on landing day was 248,000,000 km. at the speed of light (299,000 km/s) how long, in minutes, did it take the message to travel to earth?
question 1
(a) in the boxes, enter the distance between mars and earth and the speed of light in scientific notation.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

b. hoped i'm right lol

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
