Answer:
tanx = 1
Step-by-step explanation:
I assume you mean sinx = cosx
In this case we have to recognize that tanx = sinx / cosx
So if we divide cosx over we can get tanx
So:
Cosx divided by itself gives us 1
sinx / cosx = 1
tanx = 1
Answer:
<em>P(B) = 0.46</em>
Step-by-step explanation:
<u>Probability</u>
The complementary event of a given event A is defined as "not A" or the event that A does not occur.
For example, if A is defined as 'getting a job', then the complement of A is 'not getting a job'.
Event A and its complementary event (call it B) must satisfy:
P(A) + P(B) = 1
If we know P(A)=0.54, then
P(B) = 1 - P(A)
P(B) = 1 - 0.54
P(B) = 0.46
Answer:
-12 47/60
Step-by-step explanation:
-(1 1/5) + (-8 3/4 -2 5/6) = -(1 + 8 + 2 + 1/5 + 3/4 + 5/6)
= -(11 + 12/60 +45/60 +50/60) . . . 60 is the LCD of 1/5, 3/4, 5/6
= -(11 + 107/60) . . . . . . . . . . . . . . . . add the fractions
= -(12 47/60) = -12 47/60 . . . . . . . write as a mixed number
___
Your graphing calculator may be able to do this for you. Many handle mixed numbers with ease.
