Answer:
- <u><em>There are 20,000 number available.</em></u>
Explanation:
To determine <em>how many phone numbers are available </em>you need to know how many digits the number contains.
I will assume the same number of digits for other similar questions, i.e. 7.
With 7 digits, the numbers that begin with 373 or 377 can be of the form 373XXXX or 377XXXX.
Where each X can be any digit 0 - 9. Then, there are 10 different options for each X.
Thus, there are 10×10×10×10 = 10,000 different numbers starting with 373 and other 10,000 different numbers starting with 377.
In total, there are 20,000 numbers available.
Y = sin x + sin² x
y ` = f ` ( x ) = cos x + 2 sin x cos x
f `( 0 ) = cos 0 + 2 sin 0 cos 0 = 1
The tangent line formula:
y - y0 = f ` ( x0 ) ( x - x0 )
y - 0 = 1 · ( x - 0 )
Answer: y = x
Answer:
Day 24.
Step-by-step explanation:
Where 3 and 8 have a common multiple will be the day they meet. The multiples of 3 are 1, 3, 6, 9, 12, 15, 18, 21, 24, 27. The multiples of 8 are 1, 8, 16, 24, 32. 24 is a multiple of both. Rami will have both on day 24.
