<span>The decay of 277 mg of an isotope is described by the function
A(t)= 277e-0.019t,
where t is time in years.
To find the amount left after 64 years,
We substitute t = 64 in the expression.
</span>A(t=64)= 277e-0.019(64)
or A(t=64) = 277 * e-1.216
= 277 * 0.29
= 82 mg
Answer:
uuuuh no clues?
Step-by-step explanation:
We can just use the remainder theorem here.
Plug the value of -2 into each x variable.
(-2)^3 - 1
-9
<h3>The remainder is -9.</h3>
The equation of line in point-slope form of the line that passes through the point (−1, −3) and has a slope of 4 is:
y+3=4(x+1)
Step-by-step explanation:
Given
m=4
and
Point = (x1,y1) = (-1,-3)
The general form of point-slope equation of line is:

Hence,
The equation of line in point-slope form of the line that passes through the point (−1, −3) and has a slope of 4 is:
y+3=4(x+1)

Y=1/2x-4
Perpendicular means it is opposite and the reciprocal. 1/2(4) = 2-4 equals -2.
