Question
Find the perimeter of a triangle with vertices A(2,5) B(2,-2) C(5,-2). Round your answer to the nearest tenth and show your work.
perimeter of a triangle = AB+AC+BC
Using the distance formula
AB = sqrt(-2-5)²+(2-2)²
AB = sqrt(-7)²
AB =sqrt(49)
AB =7
BC = sqrt(-2+2)²+(2-5)²
BC = sqrt(0+3²)
BC =sqrt(9)
BC =3
AC= sqrt(-2-5)²+(2-5)²
AC= sqrt(-7)²+3²
AC =sqrt(49+9)
AC =sqrt58
Perimeter = 10+sqrt58
Volume of a cylinder= π r^2 h
.4= radius
π• 4^2 • 3= 150. 79
I'll help on 12. You know that 5*5 is 25. therefore what times 5 equals 20?
Let's label the man's age "x" because it's the unknown value that we're trying to find. Remember that the daughter's age is represented y "a."
x = 4a-3 would be an expression to represent the man's age :)
