Answer:
(a) Is not possible
(b) It is possible
(c) It is possible
(d) Is NOT possible.
Step-by-step explanation:
(a)
Is not possible, notice that for any function 
such that
you would have that
And for, lets say -3,3 you have that
therefore is not possible to find a function that is one to one.
(b)
It is possible. Take the following function
since 
is periodic it will take positive and negative numbers and if you multiply by 
each period will become bigger and bigger.
(c)
It is possible. Take the function
Then
and 
is one to one.
(d)
It is NOT possible because 
and that will always be positive.

Answer:
a
Step-by-step explanation:
Answer:
x = 0
Step-by-step explanation:
From the intersecting secants theorem, If from an exterior point, we draw two secant segments to a circle, then the product of the length of one secant segment and its external secant part will be equal to the product of the length of the other secant segment and its external secant portion.
Thus, applying it to this question;
(x + 27 + 48) × (x + 27) = (x + 45)²
(x + 75)(x + 27) = x² + 90x + 2025
x² + 102x + 2025 = x² + 90x + 2025
Like terms will cancel put to give;
102x - 90x = 0
12x = 0
x = 0/12
x = 0
Okay...
t-8<25
t<25 add 8 to 25
t<33
