Answer:
x = 61.92751306
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opposite / adjacent
tan x = 15/8
Take the inverse tan on each side
tan ^ -1 (tan x) = tan ^ -1 (15/8)
x = 61.92751306
The answer is A for the correct answer
Answer:
(3x^2 - 2x + 5)
Step-by-step explanation:
3x^2 - 2x + 5
- <u>(6x^3 + 3x^2)</u>
-4x^2 +8x +5
- <u>(-4x^2 - 2x)</u>
10x + 5
-(<u>10x + 5)</u>
00
(2x+1) (3x^2 - 2x + 5) = 6x^3 - x^2 + 8x + 5
Therefore the other factor of the polynomial is (3x^2 - 2x + 5)
#4(a)
row-seat: 3- 13, 4-15, 5-17, 6-19, 7-21
(b)
the equation works for row 1 but not for any of the rows after this
Ex: Row 2, S=7(2)+2, this would equal 14 but there isn't 14 seats in row #2
(c)
S=2(1)+7, there is 9 seats in row 1
2(2)+7=11, there is 11 seats in row 2
2(3)+7= 13, there is 13 seats in row 3
(d)
2(15)+7=37
2*15=30, 30+7=37
(e)
91=2(r)+7
91-7=2(r)+7-7
84=2(r)
84/2=2(r)/2
42=r, the row with 91 seats is row 42
