Answer:
1000
Step-by-step explanation:
V=4/3 π•r^3
r=6.9 ft
V=4/3 π• (6.9)^3
V=4/3 π • 328.509 ft^3
V= π•438.012 ft^3
V= 1,375.35768 ft^3
V~ 1,375 ft^3
A. (-3,5)(0,7)
slope = (7 - 5) / (0 - (-3) = 2/3
y = mx + b
slope = 2/3
(0,7)...x = 0 and y = 7
sub and find b, the y int
7 = 2/3(0) + b
7 = b....this is ur y int (0,7)
so ur equation for this line is : y = 2/3x + 7
b. (6,2)(9,4)
slope = (4 - 2) / (9 - 6) = 2/3
y = mx + b
slope(m) = 2/3
(6,2)...x = 6 and y = 2
sub and find b, the y int
2 = 2/3(6) + b
2 = 4 + b
2 - 4 = b
-2 = b...this is ur y int (0,-2)
so this equation is : y = 2/3x - 2
so " a " has a slope of 2/3 and a y int of 7 and " b " has a slope of 2/3 and a y int of -2.
ur lines are parallel lines.....parallel lines will have the same slope and different y intercepts <===
Answer:
i.e. 393650 kg.
Step-by-step explanation:
Given that Radium-226 is a radioactive substance with an annual decay rate of 0.04 %
Let the year 1937 be 0 year
Initially population was = 400,000 kg
Since decay rate is 0.04% per year after t years population would be
=
In 2017, t = 40 years (i.e. years lapsed form 1937)
Hence population
=
i.e. 393650 kg.
