Answer:

The option (A) is correct that is f(1) =0 .

Step-by-step explanation:

We can see from the given graph that it is step function

and also interpret as :

value of function at value of x are:

at x= 1 is f(1) =0

at x=2 is f(1) =1

at x=4 is f(1) =2

at x= -2 is f(1) = -1

at x= -4 is f(1) = -2

Hence, the option (A) is correct that is f(1) =0 .

Answer: $\bold{b)\quad \dfrac{-\sqrt{13}-5}{4}}$

Step-by-step explanation:

$\dfrac{3}{\sqrt{13}-5}\bigg(\dfrac{\sqrt{13}+5}{\sqrt{13}+5}\bigg)\\\\\\=\dfrac{3(\sqrt{13}+5)}{13-25}\\\\\\=\dfrac{3(\sqrt{13}+5)}{-12}\\\\\\=\dfrac{\sqrt{13}+5}{-4}\\\\\\=\dfrac{-\sqrt{13}-5}{4}$

The hypotenuse of a right triangle is 1m longer than twice one of the other two sides. The third side of the triangle is 15m. Fi

Dimas [21]

Let the length of unknown side be x

So, hypotenuse = 2x + 1

By pythagorean theorem ie , a² = b² + c²

(2x + 1)² = x² + 15²

4x² + 1 + 4x = x² + 225

3x² + 4x -224

(3x +28)(x-8)

x = -9.33 , 8

Since, length can't be negative

x = 8

∴Unknown side length = 8 m

Length of hypotenuse = 2 x 8 + 1 = 17 m

Hope it helps now.
