Answer: To figure out the answer, you have to find c, c equals 0 because adding anything from 9 + 1 equaling 0 will get you above the answer, 10. so, 9c + 1 = 10, now lets change the equation to 9c(0) + 1 = 10, c equaling zero would make the most sense because if c equals 0 then you will get 10, the answer.
Step-by-step explanation:
<u>Answer</u>
sinx = -1
<u>Explanation</u>
The graph below shown is a sine wave (sine graph).
This is because; sin0 = 0, sin90 = 1, sin 180 = 0, sin270= -1, and sin360= 0. This can be confirmed in the graph shown.
The line shown is the line, y = -1.
The two intersect at sinx = -1
Let Lisa's height be x, Ian's be y and Jim's be z
x = 10 + y . . . (1)
y = 14 + z . . . (2)
y + 14 + z + 14 = 170 + x + 14
y + z - x = 170 + 14 - 28 = 156 . . . (3)
From (2), z = y - 14 . . . (4)
Putting (1) and (4) into (3) gives,
y + y - 14 - 10 - y = 156
y = 156 + 24 = 180
Therefore, Ian's height is 180 centimeters
