Answer:

<h2>11025</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about: </h3>
  • algebra
<h3>let's solve:</h3>
  1. \sf rewrite \: 105 \: as \: 100 + 5 :  \\  \sf (100 + 5 {)}^{2}
  2. \sf use \: (a + b {)}^{2}  =  {a}^{2}  + 2ab +  {b}^{2} \:  to \: simplify :  \\  \sf  {100}^{2}  + 2.100.5 +  {5}^{2}
  3. \sf simplify \: squres :  \\  \sf 10000 + 2.100.5 + 25
  4. \sf simplify \: multipication :  \\  \sf10000 + 1000 + 25

Hi guys can you help me evaluating expressions <br><br> Please
EastWind [94]

26.) 3(2)² - 8(-3)²

= 3*4 - 8 + 9

= 12 - 8 + 9 = 13

27.) I 7 - 4(2) I

7 - 8 = -1, but  since this is absolute value, which is a number's distance from zero, your answer for 27 would be a positive one.

28.) (-2)² + 2(-3 * 1)

= 4 + 2(-3)

= 4 + (-6) = 4 - 6 = -2

29.) 7(-4)² + 5 / 4(1) - (-5)

=7 * 16 + 5 / 4 + 5

= 112 + 5 / 9 = 117/9 = 13

30.) Product: the result of a multiplication problem

Increased by: multiplied by

3(n * 7)

31.) 2n - 1

The graphs of g(x) has only one x-intercept and is an odd function. The points (0,0), (1,3), and (3,1) are on the graphs of g(x)
Eddi Din [679]

Using translation concepts, it is found that the new intercepts are given as follows:

  • x-intercept: (1, 0).
  • y-intercept: (0, -3).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

In this problem, the function was shifted one unit right, hence the rule for the translated function is given by:

(x,y) -> (x + 1, y).

The y-intercept is given by f(0), hence for the shifted function it will be f(-1). We have that f(x) is an odd function and f(1) = 3, hence f(-1) = -f(1) = -3.

The x-intercept is given by x when f(x) = 0, hence:

(0,0) -> (0 + 1, 0) = (1,0).
