Step-by-step explanation:
area = lenght × breadth
area = 5×8
area = 40
You need to find the values of x that correspond to the given values of f(x). That is, you need to solve for x:
.. y = 7x -2.7
.. y +2.7 = 7x
.. x = (y +2.7)/7
You are given y values of {14.1, 30.9, 41.4, 58.9, 68}. The corresponding x values are {2.4, 4.8, 6.3, 8.8, 10.1}, corresponding to selection C.
_____
Since the first number in each choice is different, you only need to evaluate f(x) for those numbers to see which gives the correct result. Only the 3rd one (2.4) give f(2.4) = 14.1, the correct answer.
Responder:
El ancho del modelo de área de Averi será x² + 5x-4
Explicación paso a paso:
Deje que el área del modelo de Averi sea igual a la ecuación dada
4x² + 20x-16
Si el mayor factor común del modelo es 4, esto significa que 4 se puede factorizar fácilmente de la ecuación como se muestra;
4 * (x² + 5x-4) ... (1)
Si la fórmula para el modelo de área = Largo * Ancho
Al comparar la fórmula para encontrar el área del modelo con la ecuación 1, el ancho del modelo de área será la función entre paréntesis, es decir,
x² + 5x-4
El ancho del modelo de área de Averi será x² + 5x-4
If would have to be the x+4
Treat each of the rings as a point on a graph the point being (carat, Cost ring)
Knowing this we have 2 points which we need to form a line.
(0.3, 3457); (0.5, 4373) From this we can for a slope and then an equation.
slope =
