Step-by-step explanation:
we know that
In the circle of the figure the radius is equal to 2 units
The distance from the center of the circle (origin) to the point A must be same at the radius
so
Applying the formula's distance between two points
point A( 1,y) and point (0,0)
the formula to calculate the distance between two points is equal to
substitute the values
rewrite

Answer: 39 years old
Step-by-step explanation:
First find Sarah's age.
It is said that their ages sum up to 50 and that Sarah's mother is 28 years older than Sarah.
Assume Sarah's age is x.
Sarah's mother's age would be: x + 28.
The expression would therefore be:
x + (x + 28) = 50
2x + 28 = 50
2x = 50 - 28
x = 22/2
x = 11
Sarah is 11 which means her mom is:
= 11 + 28
= 39 years old
