Answer:
Similarities:
- Both transactions have a magnitude of $25.
- Both transactions result in a change of $25 in the account.
- The absolute value is the same ($25).
Differences:
- The two transactions yield opposite results.
Step-by-step explanation:
A $25 credit results in a positive action in the account while the $25 charge is a negative action on the account.
If Cos theta = 15/17, then
Sec theta = 17/15 because cosine and secant are reciprocal functions.
Letter A
Answer:
Step-by-step explanation:
1 hr=60 min
1 km=0.62137 miles
15 km/min=(15×60) km/hr=900 km/hr=(900×0.62137) miles /hr=559.233 miles/hr

Answer:
The required result is proved with the help of angle bisector theorem.
Step-by-step explanation:
Given △ABD and △CBD, AE and CE are the angle bisectors. we have to prove that 
Angle bisector theorem states that an angle bisector of an angle of a Δ divides the opposite side in two segments that are proportional to the other two sides of triangle.
In ΔADB, AE is the angle bisector
∴ the ratio of the length of side DE to length BE is equal to the ratio of the line segment AD to the line segment AB.
→ (1)
In ΔDCB, CE is the angle bisector
∴ the ratio of the length of side DE to length BE is equal to the ratio of the line segment CD to the line segment CB.
→ (2)
From equation (1) and (2), we get
Hence Proved.
