Answer:
Step-by-step explanation:
Given the right triangle in the image, you need to remember the following identity:
Observe the triangle. You can identify that:
Then, knowing these values, you can substitute them into :
Finally, you have to solve for "x".
Therefore, the value of "x" rounded to the nearest tenth is:
Answer:
C.
Step-by-step explanation:
Given:
To find the domain of a logarithmic function, we need to take the argument, 8x, and set it greater to zero. This is because an argument of a logarithmic function cannot be zero or negative.
So since x is greater than zero, we have just found out our domain:
Interval Notation: (0, ∞)
Set Notation: {}
Answer: FIRST OPTION
Step-by-step explanation:
<h3> The missing picture is attached.</h3>By definition, given a Quadratic equation in the form:
Where "a", "b" and "c" are numerical coefficients and "x" is the unknown variable, you caN use the Quadratic Formula to solve it.
The Quadratic Formula is the following:
In this case, the exercise gives you this Quadratic equation:
You can identify that the numerical coefficients are:
Therefore, you can substitute values into the Quadratic formula shown above:
You can identify that the equation that shows the Quadratic formula used correctly to solve the Quadratic equation given in the exercise for "x", is the one shown in the First option.
