Answer:
You have a right triangle.
a^2+b^2=c^2
4^2+b^2=256
16+b^2=256
b^2=256-16
b^2=240
b=sqrt240
b=15.49 ft. ans. for the height of the ladder up the wall.
Step-by-step explanation:
Answer:
$56.875
Step-by-step explanation:
Given that :
Amount invested = principal, p = 3500
Interest rate, r = 6.5% = 0.065
Penalty on withdrawal = 3 month simple interest
Simple interest = principal * rate * time
Time = 3 months = 3/12 = 0.25 years
Hence,
Simple interest = 3500 * 0.065 * 0.25
Simple interest = $56.875
Hence, penalty paid = $56.875
