Answer:
approximately 27 grams
Work Shown:
Half life formula
y = A*(0.5)^(x/H)
where,
A = starting amount = 30 grams
H = half life period = 90 years
x = number of years that pass by = 12
y = amount left over after x years
Let's plug the values for x, A and H into the formula to find y
y = A*(0.5)^(x/H)
y = 30*(0.5)^(12/90)
y = 27.3516746567466
y = 27 .... rounding to the nearest whole number
It’s 17 units because it goes right 7 times and goes up 10 times.
Answer:
Equation of line is:
Step-by-step explanation:
Given points:
(2,-8) and (1,7)
To write the equation in point slope form.
Solution:
In order to find the equation of line, we will find the slope of the line by slope formula.
The slope of the line passing through points and is given as:
Thus, slope of given line can be given as:
∴
The point slope of the equation for line with slope passing through point is given as:
Using point (1,7) to find the equation of line.
Using distribution.
Adding 7 both sides.
