sin = 3/7
1 = sin²0 + cos²0
cos²0 = 1 - 9/49
cos²0 = 40/49
cos0 = √(40) / 7
since its in Quadrant 2 the sin is positive and cos is negative
cos0 = - √(40) / 7
Answer:
The maximum point of this function is (5,4).
Step-by-step explanation:
The maximum of a function is the maximum value that it can take.
Seeing the graph we can say that the maximum value of y occurs at x = 4. Here y = 5 corresponds to this value of x.
Therefore, the maximum point of this function is (5,4).
I hope it helps you!
B and C for the first two
138 x ? = 75
? = 75/138 = 0.544(3sf)
so about 54.35% (2dp) decrease
Answer:
D. 16 ft
Step-by-step explanation:
h = √20² - (24/2)² = √400-144 = √256 = 16
