Answer: 3x + 2 <u>></u> 53
Step-by-step explanation:
We know that
[Area of the regular pentagon]=5*[side length * apothem] / 2
side length=7.1 m
apothem=4.9 m
then
Area=5*[7.1 * 4.9] / 2-----------> 86.975 m²----------> 87 m²
the answer is 87 m²
It drops 32 feet each second so at six seconds it will have dropped 176 feet
ANSWER
The discriminant is zero.
The given equation has one real root.
EXPLANATION
The given quadratic equation is:

We rewrite this in the form;


This means that,
a=-2, b= 8, c=-8
The discriminant is given by;
D=b² - 4ac
That is:


Therefore the discriminant is zero.
This tells us that the quadratic equation has one real root.
In order words, the given quadratic equation has a repeated real root.
