Answer:
cos Ф = adj / hyp could be either 4/5 or -4/5.
Step-by-step explanation:
If sin Ф = 3/5, then we can assume that the opposite side is 3 and the hypotenuse is 5. Using the Pythagorean Theorem, we find that the adjacent side is 4:
√(5² - 3²) = √16 = ±4.
cos Ф = adj / hyp could be either 4/5 or -4/5.
A = P (1 + r/n)^nt
A = 4000(1 + 0.05/1)^(13)(1)
A = $7542.59
Answer:
Step-by-step explanation:
y = k*x This is the formula for a direct variation.
- y = 20
- x = 4 Substitute these values into the direct variation
20 = 4 * k Divide by 4
20/4 = 4k/4
k = 5
Answer: the constant of variation is 5
The definition of a coefficient is the number BEFORE the variable. So in 76x^2, the coefficient is 76.<span>
