A 22 ferry below sea depression from the sailboat
Answer:
1/6.
Step-by-step explanation:
x / 4/7 = 7/24 where x is the dividend.
7x/4 = 7/24
Cross multiply:
7x * 24 = 4*7
x = 28/(7*24)
= 28/168
= 1/6.
Answer:
f(x) = - 2(x - 3)² + 2
Step-by-step explanation:
Given
f(x) = - 2x² + 12x - 16 ( factor out - 2 from the first 2 terms )
= - 2(x² - 6x) - 16
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² - 6x
f(x) = - 2(x² + 2(- 3)x + 9 - 9) - 16
= - 2(x - 3)² + 18 - 16
= - 2(x - 3)² + 2
Answer:
(C) f’(c) = 0 and f”(c) > 0
Step-by-step explanation:
A minimum occurs where the first derivative is 0 (the tangent line is horizontal), and the second derivative is positive (concave up). The simplest example of this is a positive parabola, like y = x², which has a relative minimum at its vertex.
Answer:
Step-by-step explanation:
The unit circle has the parametric equation:
where 
in our case is the terminal side of the angle in standard position.
We substitute to get:
is the required point.
