Answer:

No it not W = 1.9

Because from

9.5 = w/0.2

W = 9.5 x 0.2

W = 1.9

The height of the Eiffel Tower is 1050 feet. From the top, the angle of depression to a soccer ball on the ground is 20 degrees.

mihalych1998 [28]

Since the angle of depression from the Eiffel tower is congruent to the angle of elevation from the soccer ball, the angle of elevation from the soccer field is 20°

Now, we can use the trigonometric function tangent to find <span>the distance from the soccer ball to the base of the Eiffel Tower:
</span> $tan( \alpha )= \frac{opposite.side}{adjacent.side}$
$tan(20)= \frac{1050}{a}$
$a= \frac{1050}{tan(20)}$
$a=2884.85$
<span>
We can conclude that </span><span>the distance from the soccer ball to the base of the Eiffel Tower is 2884.85 feet.</span>

The point-slope form of the equation of line that passes through points (8, 4) and (0, 2) is y - 4 = 1/4(x -8). What is

Mekhanik [1.2K]

Answer:

y = 1/4x +2

Step-by-step explanation:

The slope-intercept form of the equation for a line can be found by solving the given equation for y. It can be written directly from the slope and the y-intercept.

<h3>Solve for y</h3>

It is helpful to simplify the equation first, then isolate the y-variable by eliminating non-y terms from that side of the equation.

y -4 = (1/4)(x -8) . . . . . . . given

y -4 = (1/4)x -2 . . . . . . . . eliminate parentheses

y = 1/4x +2 . . . . . . . . . . add 4. This is the desired form

<h3>Use given information</h3>

Alternatively, you can use the given information to write the slope-intercept equation directly. The slope in the point-slope form is the multiplier outside parentheses. In y-4 = 1/4(x -8), the slope is 1/4.

The y-intercept is the point where the line crosses the y-axis. Its coordinates always have an x-coordinate of 0. That is, the given point (0, 2) tells you the y-intercept is 2.

Using the slope and intercept in the slope-intercept form, you get the equation you're looking for:

y = mx +b . . . . . line with slope m and y-intercept b

y = 1/4x +2 . . . . . line with slope 1/4 and y-intercept 2
