Answer:

-4/5, -3/7, 1/4, 2/3

Step-by-step explanation:

The last one is the greatest as a positive but because it's both the greatest positive but a negative it is the smallest. Since 2/3 is closest to 1 and is positive it would be the greatest. -3/7 is a smaller value than 1/4 as it's closer to 0 than 1/4 is.

-4/5, -3/7, 1/4, 2/3

I just turned them into decimals and sorted it.
-4/5 = -0.80
-3/7 = -0.42
1/4 = 0.25
2/3 = 0.67
But you can also infer without converting. -4/5 is closer to being a whole since there are 4 “pieces” out of 5, so only 1 piece left. -3/7 is farther because 4 pieces left. Same with the positive numbers. But this method doesn’t always work because some pieces can be bigger than others like 9/10 (0.90) and 5/6 (0.83)

A boat is sighted from a 50-meter observation tower on the shoreline at an angle of depression of 4 degrees moving directly towa

MAXImum [283]

Answer:

5.76 km/h

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationship between angles and sides of a right triangle. Here, we are given the side opposite the angle (angle of depression), and we want to find the adjacent side (distance from shore).

Tan = Opposite/Adjacent

tan(4°) = (height of tower)/(distance from shore)

tan(4°) = (50 m)/(distance from shore)

Then the distance from shore is ...

distance from shore = (50 m)/tan(4°) ≈ 715.03 m

At the second sighting, the distance from shore is ...

distance from shore = (50 m)/tan(12°) ≈ 235.23 m

So, the distance traveled in 1/12 hour is ...

715.03 m - 235.23 m = 479.80 m

and the speed in km per hour is ...

speed = 0.4798 km/(1/12 h) = 5.7576 km/h

The speed of the boat is about 5.76 km per hour.

F(x)=x^2-2x-3 (so I need the done in like 20 min)

Vertex point: (1, -4)

X-intercepts: (-1, 0) , (3, 0)

Y-intercept: (0, -3)

Axis of symmetry: x = 1

This function will create a parabola that opens upwards. I’m not entirely sure what I was supposed to answer. Hopefully this covered it. I’ll attach an image of the parabola in case I missed anything.
