Negative leading coefficient. Therefore it is the downward paeabola.

Discriminant of -40 therefore the parabola does not touch x-axis

so the answer is 1.

Hi there!

$3 \sqrt{54} + 2 \sqrt{24} =$
First we split up the square root into two parts.

$3 \times \sqrt{9} \times \sqrt{6} + 2 \times \sqrt{4} \times \sqrt{6} =$
Now we calculate the value of the square roots which have an integer as a solution

$3 \times 3 \times \sqrt{6} + 2 \times 2 \times \sqrt{6} =$
Multiplying the integers gives us our next step.

$9 \sqrt{6} + 4 \sqrt{6} =$
And finally we add up the roots.

$13 \sqrt{6}$

Find x. Round to the nearest tenth.

Answer:

x = 466.7 feet

Step-by-step explanation:

Finding the top angle of the triangle :

They are complementary
90° - 31°
59°

Take the tan value of this angle to find y :

tan 59° = 400/y
1.66427948 =400/y
y = 400 / 1.66427948
y = 240.344248

Using Pythagorean Theorem to find x :

y² + 400² = x²
x = √(240.344248)² + 160000
x = √57765.3575 + 160000
x = √217765.357
x = 466.7 feet (nearest tenth)
