Answer:
Step-by-step explanation:
Using the difference formula for cosine and the exact values
cos45° = sin45° = , cos30° = , sin30° =
cos(a - b) = cosacosb + sinasinb
Note 15° = 45° - 30°, thus
cos15°
= cos(45 - 30)°
= cos45°cos30° + sin45°sin30°
= ( × ) + ( × )
= +
=

Probability of the next six babies being a girl = (0.4810)^6 = 0.0124
Therefore probability of at least one boy in next six births = 1 - 0.0124
= 0.9876 Answer
The function f(x) = (x)? If that is the function, then there is no retriction on the Domain?
The right choice is: A <em>whole</em> number constant could have been <em>subtracted</em> from the <em>exponential</em> expression.
Let be an <em>exponential</em> function of the form , where and are <em>real</em> numbers. A <em>horizontal</em> asymptote exists when , which occurs for .
For this function, the <em>horizontal</em> asymptote is represented by and to change the value of the asymptote we must add the <em>parent</em> function by another <em>real</em> number (), that is to say:
(1)
In this case, we must use to obtain an horizontal asymptote of -3. Thus, the right choice is: A <em>whole</em> number constant could have been <em>subtracted</em> from the <em>exponential</em> expression.
