Answer: our fruitful chance
Step-by-step explanation:
That 's easy!!! (x-h) ²+(x-k) ²=r²
(h, k) is the coordinate of centra
r is radius
and(x-h) ²+(x-k) ²=r² is written in standard form, which u can directly get the value of center and radius
so for ur question center is (7 and -4)
radius is 7
Answer:
Step-by-step explanation:
Work = force × distance
force = mass × acceleartion due to gravity
a four ton satellite will have a force of 4× 1000 ×10 = 40KN (1000Kg = 1 ton)
1 mile = 1609.34 metre
therefore (a) 100 miles above the earth
work = 40000 × 100×1609.34
= 6437360000J
=6.4GJ
(b) 300 miles above the earth
work = 40000×300×1609.34
= 1.93×10¹⁰ J
