Answer:
7) No
8) Yes
Step-by-step explanation:
Tangent lines are perpendicular to the radius lines at the point of intersection. So we just need to check if these are right triangles.
7) c² = a² + b²
20² = 12² + 14²
400 = 340
No
8) c² = a² + b²
13² = 7.8² + 10.4²
169 = 169
Yes
Interest is basically a percentage that can be simple or compounded. Simple interest is the amount of a loan. Annual is a form of compounded interest. Compounded interest can be quarterly, monthly, weekly, yearly, etc.
I=Prt
