Answer:

Isosceles Triangle      

Step-by-step explanation:

  • Reflection symmetry exists when the figure can be folded over onto itself along a line. This line is called the line of symmetry.
  • In a regular polygon, the number of lines of symmetry is equal to the number of sides in the polygon.
  • Isosceles triangle is a type of triangle that will always have exactly 1-fold reflection symmetry.
  • 1-fold reflection symmetry means that one line or 1 division can divide the whole figure into two symmetrical parts.
  • An isosceles triangle is a triangle that has two sides of equal length. Isosceles triangle has at least one line of symmetry.

Thus, the answer is Option c) Isosceles triangle.

Write the tangent ratios for P and Q. The figure is not drawn to scale.
aliina [53]
The tangent ratio of angle P is 24/7. For angle Q, the tangent ratio is 7/24. To determine the answers, the length of the opposite side of the angle is divided by the length of the adjacent side.
tan (angle) = (opposite/adjacent)

Given the functions f (x)=\x] and g(x)= 2 x + 31 – 4 a. Determine the
Arisa [49]

Functions can be transformed through translation, dilation, etc.

  • <em>The changes are horizontal translations and vertical compression.</em>
  • <em>The domain of f(x) is </em>(-\infty,\infty)<em>, while its range is </em>(0,\infty)<em />
  • <em>The domain of g(x) is </em>(-\infty,\infty)<em>, while its range is </em>(-4,\infty)<em />

We have:

f(x) = |x|

g(x) = 2|x - 3| - 4

<u>(a) The changes from f(x) to g(x)</u>

First, f(x) was translated to the left by 3 units.

The rule is:

(x,y) \to (x-3.y)

So, we have:

f'(x) = |x - 3|

Next, the function is compressed vertically by 2

The rule is:

(x,y) \to (x,2y)

So, we have:

f"(x) = 2|x - 3|

Lastly, the function is translated down by 4 units.

The rule is:

(x,y) \to (x, y - 4)

So, we have:

g(x) = 2|x - 3| - 4

<em>Hence, the changes are horizontal translations and vertical compression.</em>

<u>(b) Analyze f(x) and g(x)</u>

<u>f(x)</u>

It spans across the x-axis; so, its domain is (-\infty,\infty)

The y values start from 0 and opens upward; so, its range is (0,\infty)

It crosses the x and y axes at 0; so its intercepts are 0.

<u>g(x)</u>

It spans across the x-axis; so, its domain is (-\infty,\infty)

The y values start from -4 and opens upward; so, its range is (-4,\infty)

It crosses the x-axis at -1 and -5; so its y-intercepts are -1 and -5

It crosses the y-axis at 2; so its x-intercept is 2

Let f(x) = x2 - 81. Find f-1(x).
aalyn [17]
The answer is <span>1) ± √x+81
</span>
Step 1: Substitute y for f(x). <span>
Step 2: </span>Since every (x, y) has its partner (y, x)y switch x and y.
Step 3: <span>Solve for y.

Step 1.
The function is:         f(x) = x</span>² - 81
Substitute y for f(x):   y = x² - 81

Step 2.
Switch x and y: x = y² - 81

Step 3.
Solve for y (which is now f⁻¹(x)): f⁻¹(x) = y
x = y² - 81
y² = x + 81
y = +-√(x+81)

Therefore, the choice 1) is correct.
