The tangent on the unit circle is y/x

<h3>How to determine the tangent value?</h3>

The point on the unit circle is given as:

Point = (x,y)

By default

(cos(ø), sin(ø)) = (x,y)

This means that:

cos(ø) = x

sin(ø) = y

The tangent of an angle is:

tan(ø) = sin(ø)/cos(ø)

So, we have:

tan(ø) =y/x

Hence, the tangent on the unit circle is y/x

Which equatin is nonlinear

Anon25 [30]

Answer: $y=\frac{5}{x}$

Step-by-step explanation: To find a nonlinear equation, the degree of the linear equation must be 0 or 1 each from its variables.

As we see here the degree of the variable is 1, so y is 1. But the degree of the variables in the equation violates the linear equation definition. Since it does that, it's not counted as a linear equation.

Therefore, $y=\frac{5}{x}$ is not a linear equation.

Solve 7n- 4(5 - 2n)=10

marta [7]

The answer you are looking for is n = -30.

This can be found by first distibuting 4 into the parenthesis (5 - 2n). This will give you 20 - 8n. Next, you add 20 to both sides, which gives you 7n - 8n = 30. Then, you'd combine like terms (7n and -8n), to get -1n. Finally, you divide bith sides by -1. This gives you a final answer of n = -30.

I hope this helps!

5/2 times x equals 1

Musya8 [376]

Answer:

$x=\frac{2}{5}$

Step-by-step explanation:

Given:

The equation to solve is given as:

$\frac{5}{2}\times x=1$

In order to solve this equation for 'x', we need to isolate 'x' from its coefficient.

The coefficient of 'x' here is $\frac{5}{2}$ which is a fractional coefficient. Therefore, we have to perform the mathematical operation twice to isolate 'x'.

Step 1: Multiply both sides by 2 to eliminate the denominator of the fractional coefficient. This gives,

$2\times \frac{5}{2}\times x=1\times 2\\\frac{2\times 5\times x}{2}=2\\5x=2$

Step 2: Divide both sides by 5 to eliminate the numerator of the fractional coefficient. This gives,

$\frac{5x}{5}=\frac{2}{5}\\\\x=\frac{2}{5}$

Therefore, the solution is $x=\frac{2}{5}$
