Answer:

D) -4 (with imaginary roots ±2i)

Step-by-step explanation:

Since you cannot take the square root of a negative number to produce a real result, the only option that has two imaginary roots is D) -4, where the two imaginary roots are 2i and -2i.

(a) use the pythagorean theorem to determine the length of the unknown side of the triangle, (b) determine the perimeter of the

Kisachek [45]

Answer:

(A) 40 km

(B) 90 km

Step-by-step explanation:

To find the missing side of this triangle, let's use the Pythagorean theorem.

$a^2+b^2=c^2$ , assuming that a and b are legs, and c is the hypotenuse.

Assuming the 9km side is a, we need to find the value of b, so we can substitute into the equation.

$9^2+b^2=41^2\\81+b^2=1681\\b^2=1681-81\\b^2=1600\\\\b = \sqrt{1600} \\b=40$

So, the length of the missing side is 40. Now that we know this piece of information, we can find the perimeter and area of the triangle.

The perimeter is all the sides added together, so $41+9+40 = 90$ km is the perimeter.

The area are the two legs multiplied divided by 2.

So,

$\frac{9\cdot40}{2} \\\\\frac{360}{2}\\\\180$

So the area of this triangle is 180 cm²

Answer:

4th option

Step-by-step explanation:

(f - g)(x)

= f(x) - g(x)

= $\sqrt{16x^4}$ - (3x² - 3x - 5)

= 4x² - 3x² + 3x + 5 ← collect like terms

= x² + 3x + 5
