Answer:
(60, 41) not in the line y = 5x + 1
Step-by-step explanation:
y = 5x + 1
(60,41) x = 60 y = 41
y = 5 x 60 + 1 = 301 ≠ 41
Answer:
Since the question doesn't mention in what tide the answer should be, I will be giving a solution to both, the high and low tide. Hope this helps :)
Step-by-step explanation:
Using a cosine function, where time is measured in hours past high
tide: y=4cos30x + 10
Using a cosine function, where time is measured in hours past low
tide: y = 4cos[30(x-6)]+10
Answer:
7y8.9 ft²
Step-by-step explanation:
Easy way:
Rotate the triangle so that the 12.1 ft side in on the bottom becomes the base.
Drop a line from the top down perpendicular to the 12.1 ft base. That makes a right triangle.
sin 71 = height/13.8
0.9455 = height/13.8
height = 13.05 ft
Area = bh/2 = (12.1)(13.05)(0.5) = 78.9 ft²
We have two fractions being divided. When we divide two fractions, we flip the second fraction and multiply
1/12 divided by 1/6 = 1/12 * 6/1
-------
From here we multiply straight across.
The numerators multiply to get 1*6 = 6
The denominators multiply to 12*1 = 12
We end up with 6/12 which reduces to 1/2 when you divide both parts by the GCF 6
<h3>Final Answer: 1/2</h3>
