A radioactive compound with mass of 260 grams decays at a rate of 3.8% per hour. Which equation represents how many grams of the compound will remain after 8 hours? A: C=260(1.038)^8C=260(1.038)^8
B: C=260(0.962)^8C=260(0.962)^8
C: C=260(0.038)^8C=260(0.038)^8
D: C=260(1-0.38)^8C=260(1−0.38)^8
1 answer:
The exponential equation that represents how many grams of the compound will remain after 8 hours is:
B: C=260(0.962)^8
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:
In which:
A(0) is the initial value.r is the decay rate, as a decimal.
A radioactive compound with mass of 260 grams decays at a rate of 3.8% per hour, hence the equation for the mass after t hours is given by:
After 8 hours , the amount is given by:
Hence option B is correct.

Answer:
perpendicular:
parallel:
Step-by-step explanation:
original line:
y = -5x + 5
=> 5x + y = 5
m = -5/1 = -5
perpendicular:
m = 1/5
L: x - 5y = k
(7, -5) -> L
7 - 5 * (-5) = k
=> 7 + 25 = 32 = k
L: x - 5y = 32
parallel:
m = -5
L: 5x + y = k
(7, -5) -> L
35 - 5 = 30 = k
L: 5x + y = 30
In the given point 4-3i, 4 is a real number and is positive and 3i is an imaginary number and is negative, so point T is on real number positive 4 and imaginary number -3i.
The answer would be D. T
