Answer:

Isosceles Right Triangle

Step-by-step explanation:

We look at the sides first. Two sides are equal, which means that the triangle is isosceles (equilateral means three equal sides, and scalene means no sides equal). Then we look at the only angle indicated, which is the right angle. Thus, we come to the conclusion that the triangle is an Isosceles Right Triangle.

Which function represents g(x), a reflection of f(x) = On a coordinate plane, 2 exponential functions are shown. g (x) decreases

Vanyuwa [196]

Answer:

$g(x)=\frac{1}{2}(3^{-x})$

Step-by-step explanation:

Given:

The graph of function $f(x)\ and\ g(x)$ are given.

The equation for $f(x)$ is given as:

$f(x)=3^x$

Now, the graph of $g(x)$ is a reflection of $f(x)$ .

The graph of $g(x)$ passes through the point (-1, 1.5) [second quadrant] and crosses the y-axis at (0, 0.5).

As evident from the graph, the functions $f(x)\ and\ g(x)$ are reflections about the y-axis.

We know the transformation rule for reflection about the y-axis as:

$f(x)\to f(-x)\\\\\therefore 3^x\to3^{-x}....(\textrm{Reflection about y-axis})$

Now, the y-intercept of the function $y=3^{-x}$ is obtained by plugging in $x=0$ . This gives,

$y=3^0=1$

So, the y-intercept is at (0, 1). But the graph of $g(x)$ crosses the y-axis at (0, 0.5). As we observe, the coordinate rule for the transformation can be written as:

(0, 1) → (0, 0.5)

$(x,y)\to (x,\frac{1}{2}y)$

So, the reflected graph is compressed vertically by a factor of $\frac{1}{2}$ .

Therefore, the transformation is given as:

$y\to \frac{1}{2}y\\\\\therefore 3^{-x}\to \frac{1}{2}(3^{-x})$

Therefore, the equation for $g(x)$ is:

$g(x)=\frac{1}{2}(3^{-x})$

The product of two consecutive odd natural numbers is 1 less than 6 times their sum. Find the numbers.

MrRissso [65]

Answer:

11 ; 13

Step-by-step explanation:

Let the numbers be :

x and x + 2

x * (x + 2) = 6(x + x + 2) - 1

x² + 2x = 6(2x + 2) - 1

x² + 2x = 12x + 12 - 1

x² + 2x = 12x + 11

x² + 2x - 12x - 11 = 0

x² - 10x + 11 = 0

x² - 11x + x + 11 = 0

x(x - 11) + 1(x - 11) = 0

(x - 11) = 0 or (x + 1) = 0

x = 11 or x = - 1

X cannot be negative

x = 11

x + 2 = 11 +2 = 13

I’m confused on this one

guajiro [1.7K]

Well, to find the hypotenuse of the small triangle (or part of the perimeter of the parallelogram), you would have to see the measurements of a 30-60-90 triangle. So, the hypotenuse is always 2x, and the side you have is x, but the one you want to find is x times the square root of 3. So, what we do now is multiply your x, which is 2 and multiply it by the square root of 3. Which is simply 2√3. Now that you have that measurement, you can easily solve for the perimeter as follows.

((2√3)*(2))+(9+2)*2

4√3+22 is the answer boyyyy :)
