Answer:

A

Step-by-step explanation:

Equation

300 ( 1 + x) = 420

Explanation

You start with 300. What fractional amount do you need to increase the original amount up to 420

Solution

Divide both sides by 300

300(1 + x)/300 = 420/300

1 + x = 1.4    

Subtract 1 from both sides.

1 - 1 + x = 1.4 - 1

x = 0.4

But as a percent this number is 0.4 * 100 = 40%

Answer

40% which is A

The table below shows selected points from a function.
FrozenT [24]

Answer:

<em>True </em>

Step-by-step explanation:

<em>Rate Of Change Of Functions </em>

Given a function y=f(x), the rate of change of f can be computed as the slope of the tangent line in a specific point (by using derivatives), or an approximation by computing the slope of a secant line between two points (a,b) (c,d) that belong to the function. The slope can be calculated with the formula

\displaystyle m=\frac{d-b}{c-a}

If this value is calculated with any pair of points and it always results in the same, then the function is linear. If they are different, the function is non-linear.

Let's take the first two points from the table (1,1)(2,4)

\displaystyle m=\frac{4-1}{2-1}=3

Now, we use the second and the third point (2,4) (3,9)

\displaystyle m=\frac{9-4}{3-2}=5

This difference in values of the slope is enough to state the function is non-linear

Answer: True
