a²+ b² = c² is the formula for pythagorean theorem.
it is used to find out the hypotenuse(the side opposite the 90° angle) of a right angled triangle.
the two sides adjacent to the 90° angles are 'a' and 'c'. the theory is that if you add the squares of a and b, the hypotenuse is equal to c².

Answer:
The cost must be $32 since that is the only cost possible for the 1st deal
Step-by-step explanation:
Let C represent the total cost of each deal
Let T be the number of trips down the water slide
C = 32 for the 1st deal since the cost is the same regardless of how much she rides
C = 18 + T for the 2nd deal
To find when the two costs are equal set them equal to each other and solve for T
32 = 18 + T
T = 14 trips
The cost must be $32 since that is the only cost possible for the 1st deal
Answer:
Step-by-step explanation:
Surface area for a sphere is 
π
,
Diameter is 10, so radius is 5. Radius is half of diameter.
A=4×π×
=
Nearest tenth:
Therefore, it is
