How to solve j + 12 = algebraically step by step

vivado [14]

Step-by-step explanation:

assuming j+12 us equal to 0

j+12=0

j+12-12=0-12 (subtract 12 on both sides)

so j is now equal to

j = -12

Hyperloop, a new mode of travel, aims to reach a speed of 170 m/s . This is 50% less than the speed of sound.

mariarad [96]

Answer:

The speed of sound is $340\ m/s$

Step-by-step explanation:

Let

x-----> the speed of sound

we know that

$50\%=50/100=0.50$

$0.50x=170$

solve for x

$x=170/0.50=340\ m/s$

If you place 35 points on a piece of paper so that no three points are in a line, how many line segments are necessary to connec

Ganezh [65]

<span>Thank you for posting your Math question here at brainly. The line segments that are necessary to be connected to each point is 34. The total number of such connection is C(35,2) = 35 * 34/2. I hope the answer helps. </span>

Three trigonometric functions for a given angle are shown below. Sine theta = Negative StartFraction 77 Over 85 EndFraction, cos

Likurg_2 [28]

Trigonometric functions are the ratio of the different sides of a right-angled triangle. We can say that the coordinates of the point are (-77, 36).

<h3>What are trigonometric functions?</h3>

Trigonometric functions are the ratio of the different sides of a right-angled triangle.

$\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}$

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

Given to us

$Sin(\theta) = \dfrac{-77}{85}$

$Cos(\theta) = \dfrac{36}{85}$

$Tan(\theta) = \dfrac{-77}{36}$

As we know that the Tangent(Tan) is the ratio of perpendicular and base. therefore, we can write the function as,

$\rm Tan(\theta) = \dfrac{Perpendicular}{Base} = \dfrac{-77}{36}$

therefore, the length of the perpendicular is 77, while the length of the base is 36.

As given to us that the value of sin is negative, therefore, the perpendicular will be on the negative side of the y-axis. While the value of cos is positive, therefore, the base will be on the positive side of the x-axis.

Thus, we can say that the coordinates of the point are (-77, 36).
