I need to know how to do this one.

Dennis_Churaev [7]

Answer:

$x \approx 11.6906$

I made the assumption those were right triangles.

Step-by-step explanation:

I like your 30 there.

I found the length in orange by doing 55-30=25.

Now we can try to find the length in light purple by doing orange length plus the length you found which is 25+30=55.

So we can use a trig function to find $x$ .

I made another picture to focus our problem more.

Now if you look at the triangle we have here and refer to trig right triangle definitions, we can setup an equation form this.

The opposite side of the angle, whose measurement is $12$ degrees, is $x$ .

The adjacent side of the angle, whose measurement is $12$ degrees, is $55$ .

So I will use the tangent ratio.

$\tan(12^\circ)=\frac{\text{opposite}}{\text{adjacent}}$

$\tan(12^\circ)=\frac{x}{55}$

Multiply both sides by 55:

$55 \cdot \tan(12^\circ)=x$

Now it is handy dandy calculator punching in time:

$11.6906 \approx x$

$x \approx 11.6906$

The force, F newtons (N) between two particles is inversely proportional to the square of the distance, d m, between them. When

allsm [11]

The force is 1.6N and the distance between them is 1.3 meters

<h3>The force between them</h3>

An inverse variation from force to the square of distance is represented s:

k = Fd^2

Where k represents the variation constant

When F = 10, d = 2.

So, we have:

k = 10 * 2^2

k = 40

Substitute k = 40 in k = Fd^2

Fd^2 = 40

When d = 5, we have:

F * 5^2 = 40

This gives

25F = 40

Divide by 25

F = 1.6

Hence, the force is 1.6N

<h3>The distance between them</h3>

In (a), we have:

Fd^2 = 40

When F = 25, we have:

25 * d^2 = 40

This gives

25d^2 = 40

Divide by 25

d^2 = 1.6

Take the square root of both sides

d = 1.3

Hence, the distance between them is 1.3 meters

If y varies inversely as x and y is 2.5 when x is 6, what is y when x is 4? a. 3.75 b. 1.67 c. 0.1 d. 7.5 Please select the best

REY [17]

Because y varies inversely as x, therefore
$y= \frac{k}{x}$
where k = constant.

When x = 6, y = 2.5. Ther efore
$\frac{k}{6} = 2.5$
Cross multiply.
k = 6 x 2.5 = 15

The equation is
$y = \frac{15}{x}$

When x = 4, obtain
$y = \frac{15}{4}= 3.75$

Answer: a. 3.75
