10 grams Vanadium will be left after 48 days
Further explanation:
Half-life is the time after which the chemical is reduced to half.
The reaming mass after half life is given by:
The formula for calculating the remaining mass after given time period is:
Here n is the number of half lives passed
Now,
Given
Mass=80 grams
Time= 48 days
Half-life = 16 days
The number of half lives will be:
Putting the values of n and mass in the formula
10 grams Vanadium will be left after 48 days
Keywords: Half-life, radioactive

Answer:
cant help you out, there are no options
Answer:
x=4
Step-by-step explanation:
4x-3=5x-7
-1x-3=-7 Subtract the 5x on both sides
-1x=-4 Add the -3 to the -7
x=4
By definition, the slope of a curve is the rate of change of the independent and dependent variables. When graphed in a Cartesian plane, the slope between any two point on the curve is equal to Δy/Δx. However, we should not that only a linear function has a constant slope. For this problem, the equation is quadratic. Hence, you must specify the point where we should get the slope.
In calculus, the slope is the first derivative of the equation:
<span>y=3x</span>²<span>-8
dy/dx = slope = 6x - 0
Thus, the slope at any point of the curve is 6x. For instance, you want to find the slope of the curve at point (1,1), then the slope is equal to 6(1) = 6 units.</span>
