Which equation would you use to find how high the bird is flying
lisov135 [29]
Hi there! The fourth answer is correct.

In the picture we have to deal with facts:
1. The angle of 45°
2. The length of the opposite side
3. The length of the adjacent side.

Since we have to use the opposite and the adjacent side, we have to use the tangent of the angle. In a formula:
\tan( \alpha ) = \frac{opposite}{adjecent}

Filling in this formula, brings us to the following answer.
\tan(45) = \frac{x}{1100}

A navigator plots the course a plane is currently traveling. The plane is 300 miles from its destination. If it continues on its
inna [77]
We have to use the rule of cosx° to solve this problem. Attached is a diagram of the navigator's course for the plane. It is similar to the shape of a triangle. We know the plane is 300 miles from its destination, so that will be one of the sides. On the current course, it is 325 miles from its destination, so that will be another one of the sides. The last side is 125 because that is the distance between the destination and the anticipated arrival. Cosx° is what we are looking for. 

To find how many degrees off course the plane is, we must use the rules of Cosx°, which is shown in the attached image. 

The plane is approximately 23° off course.

write the equation in slope-intercept form with y intercept of −3 and an x intercept of −4.5.plz help thanks!
Mashcka [7]

The equation of the line is y = -2/3x - 3.

To find this, we first need to turn the intercepts into ordered pairs.

x intercept: (-4.5, 0)

y intercept: (0, -3)

Now we can use these two points and the slope equation to find slope.

m = (y2 - y1)/(x2 - x1)

m = (0 - -3)/(-4.5 - 0)

m = 3/-4.5

m = -2/3

Now that we have the slope, we can use slope intercept form to find the intercept.

y = mx + b

-3 = 2/3(0) + b

-3 = 0 + b

-3 = b

Which allows us to model the equation as y = -2/3x - 3
