A parallelogram with congruent diagonals is a
.. B - rectangle.
Answer:
x ≈ 2.76
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan78° = 
= 
= 
( multiply both sides by x )
x × tan78° = 13 ( divide both sides by tan78° )
x = 
≈ 2.76 ( to 2 dec. places )
Answer:
Step-by-step explanation:
It's awfully deep.
1 minute = 65 meters
10 minutes = 10 * 65 = 650 meters below sea level.
Answer:
Option D is correct
Step-by-step explanation:
Option D is correct
Being an arithmetic sequence there will be common difference between the consecutive terms
Option A is incorrect because it is not necessary that explicit formula is an arithmetic sequence we can create explicit formula for any sequence
Option B is incorrect because recursive formula can be created for any sequence for geometric series also.
Option C is incorrect because the sequence that has constant ratio is the geometric sequence not an arithmetic sequence.
