Answer: The correct option is tan(F).
Explanation:
In the given figure the triangle is a right angle triangle because 
.
It is also given that 
and 
.
Since it is an isosceles right angle triangle, therefore the value of perpendicular and base is same for both angles D and F, which is 5.
The value of cos(F) is 
.
The value of sin(F) is .
The value of sin(D) is .
The value of tan(F) is 1. Which is not equal to .
The value of cos(D) is .
Therefore, the value of tan(F) is not equal to the value of cos(F), so the correct option is third.
The first answer is 3/34 sec and the second answer is 15/34 sec.
Set up a proportion for these problems. For the first question,
340/1 = 30/x
Cross multiply:
340*x = 1*30
340x = 30
Divide both sides by 340:
340x/340=30/340
x = 30/340 = 3/34
For the second question,
340/1 = 150/x
Cross multiply:
340*x = 150*1
340x=150
Divide both sides by 340:
340x/340 = 150/340
x = 150/340 = 15/34
We know the following relationship:
The
domain of a function are the
inputs of the function, that is, a function
is a relation that assigns to each element
in the
set A exactly one element in the
set B. The set A is the domain (or set of inputs) of the function and the set B contains the range (or set of outputs).Then applying this concept to our function
we can write its domain as follows:
1. D<span>

When:
?
when:
where k is an integer either positive or negative. That is:
To match this with the choices above, the answer is:

2. which identity is not used in the proof of the identity 
:
This identity can proved as follows:
The identity that is not used is as established in the statement above:

Answer: He is paid $90 last weekend.
Step-by-step explanation:
Since we have given that
Amount he earns per hour = $6
If he works on Saturday, he is paid time and a quarter .
Amount would be
If he works on Sunday, he is paid time and a half.
Amount would be
Number of hours he worked on Saturday = 6 hours
Number of hours he worked on Sunday = 5 hours
So, Total amount he is paid last weekend altogether is given by
Hence, he is paid $90 last weekend.
