Let the area of the triangle formed by the image (i.e. straight line) of the first-order function y = 2x + B and the two coordinate axes be equal to 4, and then calculate the value of B zhou

Let the area of the triangle formed by the image (i.e. straight line) of the first-order function y = 2x + B and the two coordinate axes be equal to 4, and then calculate the value of B zhou

Let x = 0, then y = B
Let y = 0, then x = - B / 2
So area 4 = | B | - B / 2 | / 2 = B & # / 4
The solution is b = ± 4
I hope I can help you. Happy study

What is the area of the triangle formed by the line y = 2x-1 and the two axes______ ．

According to the properties of the first-order function, it is found that the intersection points of the image of the function y = 2x-1 and the two coordinate axes are (0, - 1) and (- 12, 0), that is, the height is 1 and the bottom is 12. The area of the triangle enclosed by the function y = 2x-1 is 12 × 1 × 12 = 14

Who knows the qualified measurement range of lightning protection grounding resistance test and line insulation resistance test?

The grounding resistance of lightning protection should be different according to different grades of buildings

How to connect correctly when measuring insulation resistance with megohmmeter?

There are two terminals in the insulation megger, one black and one red. Generally, the black is closely connected with the ground wire, and the red wire is closely connected with the object to be measured. Rotate at a uniform speed of 120 / s, and the value read after the needle is basically stable is the insulation resistance value of the object to be measured

How to convert megohmmeter to measure electrical insulation resistance

When measuring the insulation resistance of electrical appliances, the resistance value itself is in megohm. For example, the insulation resistance value of general electrical circuits is required to be no less than 0.5 megohm. Therefore, there is no need to convert. The number of megohm is the number of pointer
If you have to convert, 1 megohm = 1000K, 1K = 1000ohm

So it was dark and the dusty air trembled
Mother came down the stairs with a flashing light
Her tall figure often came down and tied a rope around her waist,
Her shadow climbed up to the vault with a boar's head:
So she struggled with the fierce beast alone
An open book. A brown moth flutters
