Answer:

x=2,\\x=-2,\\x=\sqrt{3},\\x=-\sqrt{3}

Step-by-step explanation:

This is a quadratic in disguise. Let n=x^2. We can rewrite the problem as a quadratic to solve:

n^2-7n+12=0,\\(n-3)(n-4)=0,\\n=3,\: n=4.

Now plug in these values of n to solve:

\begin{cases}x^2=4, \:x=\pm 2\\\\x^2=3, x=\pm\sqrt{3}\end{cases}.

Therefore, our solutions are x=\pm 2, \:x=\pm\sqrt{3}.

PLz help will mark brainliest +25pts
Paha777 [63]

Answer:

54.8 Nm

Step-by-step explanation:

Torque is the cross product of the radius vector and force vector:

τ = r × F

Another way to write it is the product of the radius and force magnitudes times the sine of the angle between the vectors.

τ = rF sin θ

Here, r = 0.366 meters and F = 155 Newtons.  F is in the +y direction, and r is 15° below the +x axis, so the angle between the vectors is 90° − 15° = 75°.

τ = (0.366 m) (155 N) (sin 75°)

τ = 54.8 Nm

Y= 2x+3
Temka [501]

A standard line equation takes the form of y=mx+b

m= the slope so we see that 2 is next to x in your example

A) Slope = 2

Perpendicular lines will have the negative reciprocal of the original equation's slope

2 -> -\frac{1}{2}

B) y=-\frac{1}{2} x+3
