Consider the given right triangle.

We have to find the value of 'x'.

Consider \tan 40^{\circ}

Since \tan \Theta =\frac{P}{B}

\tan 40^{\circ} = \frac{x}{11}

Finding the value of \tan 40^{\circ} from the calculator,

We get

\tan 40^{\circ} = 0.84

Now, 0.84 = \frac{x}{11}

x = 0.84 \times 11

x = 9.24

x = 9.2 (Rounded to nearest tenth)

So, the value of 'x' is 9.2 cm.

Option 3 is the correct answer.

Answer:

Second option

Third option

Fourth option

Step-by-step explanation:

We have the following quadratic function

f(x) =(x-1)(x+7)

Use the distributive property to multiply the expression

f(x) =x^2+7x-x-7

f(x) =x^2+6x-7

For a function of the form f (x) = ax ^ 2 + bx + c the x coordinate of the vertex is:

x =-\frac{b}{2a}

Then in this case the coordinate of the vertex is:

x =-\frac{6}{2(1)}

x =-3

To obtain the y coordinate of the vertex we evaluate the function at x = -3

f(-3) =(-3)^2+6(-3)-7

f(-3) =9-18-7

f(-3) =-16

Then the vertex is:  (-3, -16)

We can see in the graph that the zeros of the function are x=1 and x=-7

Then the function is decreasing from -∞ to -3 and then it is increasing from -3 to ∞

The function is positive for x and x> 1

The correct answers are:

Second option

Third option

Fourth option
