The answer is D because to use Pythagorean Theorem it has to be a right triangle.
Irina18 [472]3 years ago
6 0

Answer:

D

Step-by-step explanation:

Hello

Pythagoras' theorem states that <u>in every right triangle</u>, the square of the length of the hypotenuse is equal to the sum of the squares of the respective lengths of the sides

if c is the hypotenuse

c^{2} =a^{2} +b^{2}

isolating a side (a)

c^{2} =a^{2} +b^{2}\\c^{2}-b^{2} =a^{2} \\a=\sqrt{c^{2}-b^{2}}

if sandra knew  the length of the hypotenuse and the length of a side could use this equation to find the other side.

the only right triangle ( an angle is 90°) in the options is the D.

Have a great day.

Determine the discriminant for the quadratic equation 0=-2x2+3. Based on the discriminant value, how many real number solutions
nekit [7.7K]

Answer:

Option D.

The discriminat is equal to 24 which

Step-by-step explanation:

The quadratic equation is

-2x² + 3 = 0

Discriminat in quadratic equation tells us the number of solution a quadratic equation has.

For example, the quadratic equation

Ax² + bx + c = 0 will have a discriminat of b² - 4ac.

b² - 4ac is equal to the value of the discriminat and equal to the number of solutions the quadratic equation has.

In our question, we have -2x² + 3 = 0

A = -2

B = 0

C = 3

b² - 4ac = 0

Substitute the values into the above equation.

0² - 4(-2 ×3) = 0

0 + -4 × -6 = 0

24 = 0

The discriminat of the equation is 24
