Answer:
Camels has to pay $42 more as interest
Step-by-step explanation:
We are given that Carmela borrows $400 and will pay 5.25% yearly simple interest.
Principal = $400
Rate of interest = 5.25%
Time = 2 years
Formula :
So,
SI=42
She borrows the money for 4 years instead of 2 years,
So,
SI=84
Difference in interests = 84-42 = 42
Hence Camels has to pay $42 more as interest

Answer:
The equation is true
Step-by-step explanation:
The best way to check if this equate is true is to convert the pi in radians to degree and actually evaluate the trigonometric terms.
Mathematically we know that pi = 180 degrees
So pi/8 = 22.5
and pi/4 = 180/4 = 45
So let’s make our check.
Insert pi = 22.5 and pi = 45
So we have;
tan 22/5 = √(1-cos45)/(1+cos45)
Now let’s evaluate this using a calculator.
tan 22/5 = 0.414213562373
The term in the root; 0.171572875254
The square root of this number is
0.41421356237
This is exactly as what is obtained with the tan 22.5
So we conclude that what we have is true
