Answer:
<h3>#6</h3>
Positive numbers less than 100 are 1 through 99.
- 1- digit = 3 numbers, zero excluded
- 2- digit = 3*4 = 12 numbers, zero excluded for the first digit
<u>Total:</u>
<u>Repetition is not allowed:</u>
- 1- digit = 3 numbers as above
- 2-digit = 3*3 = 9 numbers, minus one for the second digit
<u>Total:</u>
<h3>#7</h3>
abcd is the number.
- a = 2, then d = 4 or 0, b = 3 options, c = 2 options
- a = 3, no options
<u>Total:</u>
Answer:
-1
Explanation:
3π / 4 = (3*180) / 4 = 135 degrees
Since 135 is in the 2nd quadrant, therefore:
tan (135) = - tan (45) = -1
cot θ = 1/tanθ
Therefore:
cot (3π / 4) = 1/tan(3π / 4)
cot(3π / 4) = -1
Hope this helps :)
