One leg of an isosceles right triangle measures 5 inches. Rounded to the nearest tenth, what is the approximate length of the

Anestetic [448]

By definition, in an isosceles triangle, the two legs will have congruent lengths.

Since we know that one leg measures 5 inches, we know the other must measure 5 inches as well.

The Pythagorean Theorem states that in a right triangle, a² + b² = c².

Knowing that, we can substitute in our known values.

(5)² + (5)² = c²

From there, we can square our values.

(25) + (25) = c²

And from there, we can add the values together.

(50) = c²

Finally, we can find the square root of both values to give us the length of the hypotenuse.

7.07106781187 = c

And since we're rounding to the nearest tenth, we can rewrite this answer as:

7.1 = c

Therefore, the approximate length of the hypotenuse is 7.1 inches.

Hope this helped! :)

Consider the function f(x) = the quantity x squared minus x minus 12 all over the quantity x plus 3. Describe the graph of this

FromTheMoon [43]

Answer:

The graph of f(x) is discontinuous at x= -3. The x and y-intercepts or he function f(x) are (4,0) and (0,-4) respectively. The graph of the function is a straight line.

Step-by-step explanation:

The given function is

$f(x)=\frac{x^2-x-12}{x+3}$

$f(x)=\frac{x^2-4x+3x-12}{x+3}$

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

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

Cancel out the common factor (x+3).

$f(x)=x-4$

It is a linear equation and it will give a straight line.

Put x=0, to find the y-intercept.

$f(x)=0-4$

$f(x)=-4$

Therefore the y-intercept is (0,-4).

Put x=0, to find the x-intercept.

$0=x-4$

$4=x$

Therefore the x-intercept is (4,0).

At x= -3 the value of denominator is 0, therefore the function is undefined for x= -3.

As x approaches toward x=-3 from left and right, the value of function approaches towards y=-7.

The function is discontinuous at x= -3.

12. Algebra Two similar figures are similar based on

algol [13]

Answer:

a = ± 2

Step-by-step explanation:

Let the scale factor is k.

Then the transformation is:

(x, y) → (kx, ky)

We have:

(x, y) → (12x, 3a²y)

The scale factor is k = 12, find the value of a:

3a² = 12
a² = 4
a = √4
a = ± 2
