(a) and (b) looks correct

(c) Here's how my table looks like:

15 -18 324
27 -6 36
28 -5 25
34 1 1
42 9 81
52 19 361
SUM 828

(d) Take the sum of 828 and divide it by 6 to get 138. Now take the square root of 138 to get the standard deviation:

sqrt(138) ≈ 11.75

Answer:

f(x) is linear

g(x) is exponential

Step-by-step explanation:

A linear function will always have the same rate of change between equally distant points, while an exponential function will have an increasingly large rate of change between equally distant points.

First, look at f(x). All these points are equally distant at 2 units apart on the x-axis, so they can be directly compared:

$(-38)-(-18)=-20\\(-58)-(-38)=-20\\(-78)-(-58)=-20$

All of these points are the same distance apart on the y, so f(x) must be a linear function.

Now look at g(x). These are also all equally distant at only 1 unit apart.

$30-10=20\\90-30=60\\270-90=180$

These are very clearly not the same distance apart on the y, so g(x) must be the exponential function.

Find all the square roots of x2 ≡ 53 (mod 77)

Nikolay [14]

Answer:

$x=\pm\sqrt{77n+53}$

Step-by-step explanation:

We have been given an equivalence equation $x^2\equiv 53\text{ (mod } 77)$ . We are asked to find all the square root of the given equivalence equation.
