Answer:tan (7pi/8) = -4.4142
Explanation:The tangent half-angle formula is shown in the attached image
We have:
alpha = 7pi / 8
alpha/2 = 7pi / 16
Substitute in the formula with the alpha and alpha/2 as follows:tan (7pi/8) = [2tan(7pi / 16)] / [1 - tan(7pi / 16)tan(7pi / 16)]
tan (7pi/8) = -4.4142
Hope this helps :)

Step-by-step explanation:
<u>Given rectangle ABCD with coordinates:</u>
- A(1, 2), B(3, 2), C(3, 4), D(1, 4)
The rectangle is rotated 90 degrees clockwise.
<u>The rule for this rotation is:</u>
<u>Point B mapped to B' as per above rule:</u>
Answer: student tickets = 208
Adult tickets = 97
Step-by-step explanation:
x + y = 305
x = 305 - y
5x + y = 693
Substituting
5 (305 - y) + y = 693
1525 - 5y + y = 693
-4y = -832
y = 832 / 4 = 208
Answer
Well first you need to remove parentheses by multiplying factors. Next
use exponent rules to remove parentheses in terms with exponents. Then
combine like terms by adding coefficients. Finally you just
combine the constants.
You could do:
1 mile : 1,760 yards.
So, you would multiply 1790 times 2 and get 3520. The closest thing to 4500 yards is 3520.
So you get 2 miles and 980 yards.
