Answer: Choice B)
Exponentials undo logarithms, and vice versa. The base of the log and the exponential are the same in this problem.
Answer:
Step-by-step explanation:
Sector = theta/360° × pi×radius×radius
40/360×22/7×10×10
4/36×22/7×100
1/9×22/7×100
22/63×100
2200/63=34.92 sq feets (approximately)
Option C is the answer . Don't get confused with decimals as maybe the person who provided these options used pi =3.14 instead of what i used i.e. =22/7.
Answer: FIRST OPTION
Step-by-step explanation:

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.
