Answer:
7/17 and 1/9 0r 9/1
Step-by-step explanation:
C' ( 4, -2 )
this is the explanation sort of
c ( -2, -3 ), since it is translated six units to the right, add 6 to the x-coordinate and since it is translated one unit up, add 1 to the y-coordinate
Answer:
85.5 minutes
Step-by-step explanation:
The amount of an element that will remain after time t can be expressed as a function of initial amount N0, time t, and half life th as;
Nt = N0 × e^(-λt)
Where;
Decay constant λ = ln(2)/th, substituting into the equation;
Nt = N0 × e^(-ln(2)t/th)
We need to make t the subject of formula;
Nt/N0 = e^(-ln(2)t/th)
ln(Nt/N0) = -ln(2)t/th
t = ln(Nt/N0) ÷ -ln(2)/th
Given;
Initial amount N0 = 760g
Final amount Nt = 11 g
Half life th = 14 minutes
the nearest tenth of a minute, would it take the element to decay to 11 grams can be derived using the formula;
t = ln(Nt/N0) ÷ -ln(2)/th
Substituting the given values;
t = ln(11/760) ÷ -ln(2)/14
t = 85.5 minutes
$45 - 15% = $38.25
$53 - 20% = $42.04
So the Forever 21 dress would cost less.
Hope this helped.
Slew lines are lines that don’t intersect (or cross over one another) and don’t lie on the small plane. So for an example, if you pick a line on the floor and a line on one of the walls, they would be skew lines because they are on different planes. It they also can’t intersect each other.
