Answer:
You can use the coordinates of a figure to find its dimensions by finding the distance between two points. To find the distance between two points with the same x-coordinates, subtract their y-coordinates. To find the distance between two points with the same y-coordinates, subtract their x-coordinates.

Answer:
Dave is 6 years 4months 16 days 12 hours old
Step-by-step explanation:
Age of Dave Dog = 10year( 1 decade)+ 9 months+3 days
Age of Dave=

= 6 years 4months 16 days 12 hours
∛x-1+3 = 0
Add -3 to both sides to give ∛x-1 = -3.
Now cube both sides to give x - 1 = -27. Add 1 to both sides to find x, which is -26.
Answer:
x < −1
Step-by-step explanation:
-2x + 5 < 7
- -2x < 7 -5
- -2x < 2
- x < 2 ÷ -2
- x < -1
Answer:
f(x) = 1500(0.97)ˣ
Step-by-step explanation:
Given that:
f(x) = abˣ
a is the initial bone density, that is the bone density at 0 years, x is the number of years and b is any real value. For an exponential growth, b > 1 while for an exponential decay, b < 1.
Since the bone has a current density of 1,500 kg/m³, hence a = 1500.
The density is lost at a rate of 3% annually, therefore b = 100% - 3% = 97% = 0.97.
Therefore substituting the values of a and b into the function gives:
f(x) = 1500(0.97)ˣ
