the answer shoulldd be 136°
Answer:
(a) 25
(b) (5+4)*2 +6 -2*2 -1
(c) see below
Step-by-step explanation:
(a) evaluating exponents:
6*7 -9*9 +64
Evaluating products:
42 -81 +64
Evaluating sums:
-39 +64
25
__
(b) The last three terms of the expression sum to +1, and it is fairly easy to modify the first two terms to make one term that has a value of 18. Then the expression evaluates as 18+1 = 19.
(5+4)*2 +6 -2*2 -1
__
(c) Evaluating parentheses:
= 9*2 +6 -2*2 -1
Evaluating products:
= 18 +6 -4 -1
Evaluating sums (left to right):
= 24 -4 -1
= 20 -1
= 19
Answer:
No
Step-by-step explanation:
Answer:
Correct choice is A
Step-by-step explanation:
If a function has an inverse, then there is at most one x-value for each y-value.
The tangent function is periodic with period
Hence, at each value for which
is defined,
for each integer n. Therefore, the function
does not have an inverse. Since tangent is not a one-to-one function, the domain must be limited. From examining the graph of the tangent function, we see that in each interval of the form

where k is an integer, the tangent function assumes every value in its range. Moreover, in each such interval, each y-value is achieved exactly once. Hence, we can create an invertible function by restricting the domain tangent function to one such interval. Such interval is an interval between two consecutive vertical asymptotes
and
