Answer:

Step-by-step explanation:

If y varies directly with x, we have:

$y \propto x\\$Introducing the constant of proportionality, k\\y=kx$

When y=12, x=4

Substituting these values into the equation

12=4k

k=12/4

k=3

The constant of proportionality is 3.

The function f(x) = 1.25x + 12 represents the cost, in dollars, of a large pizza with x toppings. What does the 1.25 represent?

statuscvo [17]

1.25 represents the cost of each of the toppings in the pizza and the price of the pizza without the toppings is the (12) and f(x) is the total cost of the pizza

Help me pleasseeeee!!! its about algebraic properties of limits!

$\text{Hello there! :)}$

$3. \sqrt{2} \\\\\text{4. 0}\\\\\text{5. dne}$

$\text{To find the overall limit, they must approach the same y-value from each side:}$

$\\\\3. \lim_{x \to \frac{\pi }{4} } 2sinx ={\sqrt{2}$

$\text{Therefore:}\\\\3. \lim_{x \to \frac{\pi }{4} } f(x)= {\sqrt{2} }$

$\text{For this question, evaluate the limit from the RIGHT-HAND side:}\\\\4. \lim_{x \to \pi +} f(x)\\\\ \text{Use the equation tanx to evaluate since it involves values greater than \pi:}\\\\$

$\lim_{x \to \pi +} tanx = 0\\\\\text{So:}\\\\ \lim_{x \to \pi +} f(x) = 0$

$5. \\\\\text{Evaluate the overall limit. Make sure both sides approach the same y=value:}\\\\ \lim_{x \to \pi } 2cosx= -2\\\\ \lim_{x \to \pi } tanx = 0\\\\ \text{ Therefore:}\\ \lim_{x \to \pi } f(x) = dne \text{ (Does not exist})$
