How do I find the constant of proportionality from a equation

1 answer:

7 0

Answer:The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

Listed in the table is the percentage of students who chose each kind of juice at lunchtime. use the table to determine the meas

3241004551 [841]

Answer: 108°

Step-by-step explanation:

Since, by the given table,

The percentage of the students who choose orange juice = 30 %

Thus the fraction that choose orange juice = $\frac{30}{100}=\frac{3}{10}$

Hence, out of total students 3/10 part of students choose orange juice.

Now for finding the central angle,

$\text{ The central angle of 1 part of total students} = 360^{\circ}$

⇒ $\text{ The central angle of }\frac{3}{10} \text{ part of student}=\frac{3}{10}\times 360^{\circ}$

⇒ $\text{ The central angle of }\frac{3}{10} \text{ part of student}=\frac{1080}{10}$

⇒ $\text{ The central angle of }\frac{3}{10} \text{ part of student}=108^{\circ}$

That is, the central angle of the students who choose orange juice is 108°

Hence, Fourth option is correct.

The graph below shows a quadratic function f(x) and an absolute value function g(x)

Sophie [7]

Answer:

The x-values that are approximate solution of the equation $f(x) = g(x)$ are $x_{1} \approx -3.5$ and $x_{2}\approx 5$ , respectively.

Step-by-step explanation:

From graph we infer that the x-values that represents a solution to the system of equations corresponds to those values of x in which both functions coincide. As we see, there are two x-values for $f(x) = g(x)$ , which are described below:

$x_{1} \approx -3.5$ and $x_{2}\approx 5$

The x-values that are approximate solution of the equation $f(x) = g(x)$ are $x_{1} \approx -3.5$ and $x_{2}\approx 5$ , respectively.
