4th quadrant is positive x (cos) and negative y (sin)
Use the Pythagorean Theorem to calculate the value of y (sin).
x² + y² = c²
5² + y² = 13²
25 + y² = 169
y² = 144
y = 12
Since the y-value is negative in the 4th quadrant, then y = -12
Answer:
domain and range is -∞,+∞
Step-by-step explanation:
To find the inverse function, interchange the variables and solve for y.
h^-1 (x) = -9 - 3x/2
Answer:
The % of of acid in solution = 63.88 ml
Step-by-step explanation:
The solution of acid and water = 351 milliliters
The % of of acid in solution = 18.2% of 351 ml
Or, The % of of acid in solution =
× 351 ml
Or, The % of of acid in solution = 63.882 ml
Hence ,The % of of acid in solution = 63.88 ml Answer
