The function representing the cost per share, C, relative to the number of contributors, n, is C = 500 / n. For the contribution to be $20 each, Jane must gather 20 additional contributors, totaling 25. With just 5 currently, she needs 20 more to reach this goal.
Since the angles are complementary, it follows that sin A = cos B and sin B = cos A
therefore sin A + sin B = 0.55 + 0.83 = 1.38

Step-by-step explanation:
Answer:
28.4 cm
Step-by-step explanation:
The perimeter of the triangular wall is determined by adding all sides of the right triangle.
The triangle's height is given as 6 cm.
The hypotenuse measures 12 cm.
Using the Pythagorean theorem to find the third side:
Hypotenuse² = opposite² + adjacent²
Assigning the height as opposite = 6 cm, we find:
12² = 6² + adj²
Thus, adj² = 12² - 6²
Which gives us adj² = 144 - 36
So, adj² = 108
Leading to adj = √108
Thus, adj = 10.39 cm
The perimeter totals = 6 cm + 12 cm + 10.39 cm
= 28.39 cm
= 28.4 cm when rounded to the nearest tenth.
