Webf(x) = -0.5 * x - 2 g(x) = 2 * cos(π / 4 * x) f(g(x)) = -0.5 * (2 * cos(π / 4 * x)) - 2 Which we can further simplify as f(g(x)) = -cos(π / 4 * x) - 2 Of course you could forgo composing the functions and evaluate each function separately. Either way, you'll find that f(g(x)) ~= -3. WebAs an example, suppose we solved 2x+3=7 and got x=2. If we want to plug 2 back into the original equation to check our work, we can do so: 2x+3=7 @ 2. Since the answer is right, Algebra Calculator shows a green equals sign. If we instead try a value that doesn't work, say x=3 (try 2x+3=7 @ 3), Algebra Calculator shows a red "not equals" sign ... sight seeing sacramento ca

WebThis paper presents a new family of spreading code sequences called hybrid prime code (HPC), to be used as source code for the optical code division multiple access (OCDMA) network for large network capacity. The network capacity directly depends on the number of available code sequences provided and their correlation properties. Therefore, the … WebDifferent information sources (S x, x = 1…n, in Figure 1) ... in a case of phase equals to 5 degrees, the spaces defined between the limits +L2 = +5 and −L2 = −5; shifting is made between these two values. Similarly, when the frequency change is chosen to be between 2410 MHz and 2414 MHz, 2414 MHz and 2410 MHz are assigned to +L2 and -L2 ... WebGraph x-5=0. x − 5 = 0 x - 5 = 0. Add 5 5 to both sides of the equation. x = 5 x = 5. Since x = 5 x = 5 is a vertical line, there is no y-intercept and the slope is undefined. Slope: … sightseeing sally
