Answer:

0.925 or 92.5%

Step-by-step explanation:

y=a(1-b)^x

decay factor is 1-b <- and the part we care about

b is 7.5%=0.075

1-0.075

=0.925

Answer:

$x < -20$

Step-by-step explanation:

Given the following question:

$x+8 < -12$

In order to solve one step inequalities, we solve how we would normally solve a one-step equation and then graph the answer on a number line.

$x+8 < -12$
$8-8=0$
$-12-8=-20$
$x < -20$

<u>Now to graph the inequality on a number line, keep a few things in mind:</u>
. x is less than -20 which means the line would go the opposite way of the negative 20.
. < is a greater than sign, not a greater than or equal sign (≤) so the number line will have a open point.
. The number line will have a point on -20.

Hope this helps.

Answer:

Rational Functions

Step-by-step explanation:

1)

$f(x) = - \frac{x + 6}{2x + 3}$

• State the domain

X ∈ R : $x \neq - \frac{3}{2}$

• End Behaviour

$x \rightarrow \infty , y \rightarrow -\frac{1}{2}$

• Horizontal and Vertical

$y= -\frac{1}{2} , x=-\frac{3}{2}$

• Graphic (Annex)

2) $f(x) = \frac{3x − 6}{x}$

• State the domain

X ∈ R : $x \neq 0$

• End Behaviour

$x \rightarrow \infty , y \rightarrow 3$

• Horizontal and Vertical

$y= 0$

• Graphic (Annex)

3) $f(x) = \frac{3}{x^2-25}$

• State the domain

X ∈ R : $x \neq 5.5$

• End Behaviour

$x \rightarrow +/-\infty , y \rightarrow 0$

• Horizontal and Vertical

$y= 0 , x=+/- 5$

• Graphic (Annex)

4) $f(x) = \frac{ x^2-2}{x^2+2x-3}$

• State the domain

X ∈ R : $x \neq (3,1)$

• End Behaviour

$x \rightarrow +/-\infty , y \rightarrow +/- 1$

• Horizontal and Vertical

$y= 1 , x= (-3,1)$

• Graphic (Annex)

5) $f(x) = \frac{ x^2 − 5x − 4}{x + 1}$

• State the domain

X ∈ R : $x \neq -1$

• End Behaviour

$x \rightarrow +/-\infty , y \rightarrow +/ \infty$

• Horizontal and Vertical

$y=none , x= -1$

• Graphic (Annex)

6) $f(x) = \frac{ 5x }{x^2 + 9 }$

• State the domain

X ∈ R

• End Behaviour

$x \rightarrow +/-\infty , y \rightarrow 0$

• Horizontal and Vertical

$y= 0 , x= none$

Desmis Unit 7 Practice Day 1

Tema [17]

The number of unique triangle can be formed using the angles 30 degrees, 90 degrees and 100 degrees is 0.

<h3>What is triangle angle sum theorem?</h3>

According to the triangle angle sum theorem, the sum of all the angle(interior) of a triangle is equal to the 180 degrees.

The measure of angles are given as,

A 90 degree angle
A 100 degree angle
A 30 degree angle

To create a triangle with these angles, the sum should be equal to 180 degree of three angles.

90+100+30 > 180

90+90+30 > 180

90+90+100 > 180

100+100+30 > 180

30+100+30 < 180

30+90+30 < 180

There is no combination of angles, which is equal to the 180 degree.

Hence, the number of unique triangle can be formed using the angles 30 degrees, 90 degrees and 100 degrees is 0.
