How does f(x) = 3 ^x change over the interval x = 4 to x= 5

zloy xaker [14]

Answer:

f(x) = 3^x increases steadily on the interval [4,5].

Step-by-step explanation:

This exponential function f(x) = 3^x has a positive base (3) which is larger than 1. Thus, this function continues to increase as x increases, including the case where x increases from 4 to 5.

PLEASE HELP 15 points for brainliest! What is the solution of n^2-49=0

creativ13 [48]

Answer: The correct option are (1). c, (2). d and (3). (b).

Step-by-step explanation: The calculations are as follows:

(1) We are to find the solution of the following quadratic equation:

$n^2-49=0.$

We have

$n^2-49=0\\\\\Rightarrow n^2=49\\\\\Rightarrow n=\pm7~~~~~\textup{[taking square roots on both sides]}$

Thus, the correct option is (c). $\pm7.$

(2) We are to find the solution of the following quadratic equation:

$x^2+64=0.$

We have

$x^2+64=0\\\\\Rightarrow x^2=-64.$

Since there is no real number whose square is negative, so this equation has no solution.

Thus, the correct option is (d). no solution.

(3) We are given to find the side length of a square with an area of 144x².

Let, 'a' denotes the side length of the square.

Then,

$a^2=144x^2\\\\\Rightarrow a=\pm12x.~~~~~~~\textup{[taking square root on both sides]}$

Since the length of the side cannot be negative, so the side length is 12x.

Thus, (b) is the correct option.

The correct option are (1). c, (2). d and (3). (b).

1) A regular hexagon is mapped onto itself every time it is rotated

Ira Lisetskai [31]

A regular hexagon has angles that measure 360/6=60°, between 0° and 360°, the multiples of this angle is 120°, 180°, 240°, 300°. Thus when the hexagon is rotated through this angles, it will be mapped onto itself. When rotated through any other angle, the same result won't be possible.
Thus we conclude that the hexagon it's mapped into itself every time it is rotated.
