Answer:

The value of x is 19.

Step-by-step explanation:

We know that both of these expressions are equal because of vertically opposite angles. Let's solve.

=> 7x - 8 = 6x + 11
=> 7x - 6x = 19
=> x = 19

Hence, the value of x is 19.

Answer:

x= 19

Step-by-step explanation:

Recall the Vertical Angles Theorem which states that when two lines intersect, vertical angles are congruent. In this case, 7x-8 and 6x +11 are vertical angles, so they are congruent. We can conclude that an equation can be made to find the value of x where:

$7x-8=6x+11$

Solve out the equation to find the value of x.

$7x-8+8=6x+11+8$

$7x=6x+19$

$7x-6x=6x+19-6x$

$x=19$

The radius r of a circle can be written as a function of the area A with the following equation: r= sqrt(A/pi) What is the domai

Zepler [3.9K]

The domain of the function is \[A \ge0\] If A is negative we get an imaginary number for the radius. This makes sense because the area of a circle cannot be negative.

(8Q) Tell whether the function exhibits damped oscillation. If it does, identify the damping factor and tell whether the damping

dezoksy [38]

Answer:

Option c.

No damping

Step-by-step explanation:

We can easily solve this question by using a graphing calculator or any plotting tool.

The function is

f(x) = (√11)*cos(3.7x)

Which can be seen in the picture below

We can notice that f(x) is a cosine with maximum amplitude of (√11). Neither this factor nor the multiplication of x by 3.7 serve as a damping factor since they are constants.

f(x) does not present any dampening
