Step-by-step explanation:
Arccos(cos 7pi/2)
cos 7pi/2 = cos 630 = cos (630-360) = cos 270 = 0
arccos(0) = 90 since cos 90 = cos 270
(x): 0 - 30 - 45 - 60 - 90
sin (x) 0 - 1/2 - 1/2 √3 - 1/2 √3 - 1
cos (x) 1 - 1/2 √3 - 1/2 √3 - 1/2 - 0
tan (x) 0 - 1/√3 - 1 - √3 - ∞
Rules for sin cos tan value in each quadrant :
quadrant = I(0-90) - II (90-180)- III(180-270) - IV(270-360)
sin (x) = positive- positive - negative - negative
cos (x) = positive- negative- negative - positive
tan (x) = positive- negative- positive - negative

Answer:
2/3 feet.
Step-by-step explanation:
The formula for finding the area of a triangle is A = (B x H)/2. Or, area is equal to base times height, all divided by two. In your case, we don't know the base. If we substitute in values, we get 2/5 = (B x 6/5)/2.
Next, we have to multiply both sides by two, to cancel the "/2." That results in 4/5 = B x 6/5. Then, to isolate the variable, we have to divide both sides by 6/5. 4/5 ÷ 6/5 is 4/5 x 5/6. The fives cancel out, and we are left with 4/6.
Finally, we simplify! 4/6 simplifies to 2/3.
Answer:
Reliable financial information includes
information that can be confirmed
newspaper articles written by experts in this field
books written by experts
Step-by-step explanation:
Given: Reliable financial information
Definition of Reliable financial information is the financial information that has acquired is trued one or the one which has good quality and can be assured 100 because incomplete or not assured information may lead to financial loses.
1) information that can be confirmed : It is the trusted information because it has confirmation hence it is a reliable information.
2) information from a friend: It is not a trusted information hence it is not a reliable information.
3) data collected thirty years ago: financial data varies each day hence data collected thirty years ago is not a reliable information.
4) newspaper articles written by experts in the field: it is data provided by experts in the field and it can be trusted hence it is a reliable information.
5) books written by experts : it is data provided by experts in the field and it can be trusted hence it is a reliable information.
