a, b, c, and d are constants. If the equation crosses the x-axis at 0, -2, 3, and 5, which of the following is a factor of ? ()A. x-2B. x+3C. x-5D. x+5 答案 C 相关推荐 1In the equation . a, b, c, and d are constants. If the equation crosses the x-axis at...
The roots are the y-values where the graph crosses the x-axis. To find the factors from the roots, consider what expressions would produce a value of zero. Thus, if the roots are at 0, -2, 3, and 5, then the factored form of this equation must be x(x+ 2)(x-3)(x -5) ...
If Line k in the xy-plane has equation y = mx + b, where m and b are constants, what is the slope of k? (1) k is parallel to the line with equation y = (1-m)x + b +1. (2) k intersects the line with equation y = 2x + 3 at the point (2, 7)....
aThe equation takes the form of an extended error function in which the constants c and n are functions of the slope inclination, and the K-constant is a function of the slope inclination and the depth of the slip surface. 等式采取常数c和n是倾斜倾向的作用一种延长的误差函数的形式,并且K恒定...
(7)(7)σH=ν1−νσv−ν1−ναpp+αpp+E1−ν2εy+νE1−ν2εxwhere α, εx and εy are constants. Units for σH are MPa but these are also converted to pounds per square inch (psi) for this study to compare with casing and cement strength. The pore pressure ...
First, we calibrated a Peng-Robinson Equation of State (PR-EOS) for CO2-, and air-water systems. Second, we solved continuity, energy and momentum equations and modelled transient conductive heat transfer through the well. Third, we investigated the effects of mass flow rate, transient heat ...
The statistical structure of the environment is often important when making decisions. There are multiple theories of how the brain represents statistical structure. One such theory states that neural activity spontaneously samples from probability distr
and lobsters, which are leftovers from the seafood business. Specific properties that make chitosan an efficient adsorbent include its macromolecular structure, cationic, availability, low-cost, eco-friendly nature, and interactive amino and hydroxyl functionalities29. It has been described as possessing ...
This paper presents a physics-informed neural network (PINN) approach for monitoring the health of diesel engines. The aim is to evaluate the engine dynamics, identify unknown parameters in a “mean value” model, and anticipate maintenance requirements.
The first work in this field goes back to [20,21], which focused on the solution densities of a differential equation: 𝑑𝑔𝑑𝑥=(𝑥−𝑎)𝑔𝑏0+𝑏1𝑥+𝑏2𝑥2, where the constants 𝑎, 𝑏0, 𝑏1 and 𝑏2 are expressed as functions of the first four moments ...
