Block example: $$ x = {-b \pm \sqrt{b^2-4ac} \over 2a} $$ renders as: x = − b ± b 2 − 4 a c 2 a Block example 2: This $$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \rig...
Which of the following functions best describes this graph? a. {eq}-x^4 -2x^3 - 5x^2 + x + 1 {/eq} b. {eq}x^4 + 2x^3 - 5x^2 + x + 1 {/eq} c. {eq}x^4 -2x^3 + 5x^2 + x + 1 {/eq} d. {eq}x^4 -2x^3 - 5x^2 +...
Find the point on the x-axis at which the graph of f crosses it. What is f(x) at this point? Roots: The roots of a function are defined as where the function {eq}\displaystyle f(x) {/eq} touches the x-axis. The roots of functions are used to ...
Use the Vertical Line test to determine whether y is a function of x.The function is x^2 + y^2 = 25.The graph is given below.Use the Vertical Line Test to determine whether y is a function of x.The function is x^2 = 2xy - 1 and the graph is given below.Dete...
Answer to: The variables x and y vary inversely. When x = -12, y = 2/3. Determine the equation which relates x to y. By signing up, you'll get...
inCx. quinquefasciatusmosquitoes7. If adaptation in the mosquito flagellar ear is complete – as has been shown forDrosophilabefore – then the flagellar steady-state stiffness represents the combined elasticity of those components that suspend the sound receiver, but which do not directly contribute...
Between two variables {eq}x {/eq} and {eq}y {/eq}, direction variation occurs when variables are related by the equation {eq}y = kx {/eq}. In this case, {eq}k {/eq} represents any non-zero constant and can symbolize...
The indifference curve is a graphical representation of all the combinations of two goods and services that provide an equal level of satisfaction or utility to the consumer. Generally, the indifference curve slopes downwards because increased consumption of one good requires a ...
Consider the following function: f(x) = ln(4- ln(x)). Find the interval where the function is decreasing. Consider the function f(x)=xsqrt(50-x2). Find the interval where the function is decreasing. Consider this function: f\left ( x \right...
