Dicriminant of x² – 49 = 0

Mama L [17]

Answer:

196

Step-by-step explanation:

The discriminant (Δ) is given by:

$\Delta = b^2-4ac$

Where the polynomial is in the form:

$ax^2+bx+c=0$

In this problem, a = 1, b = 0, and c = -49. Thus, plugging it into the formula:

$\Delta = 0^2-4(1)(-49) = -(-196) = 196$

Thus, the discriminant of x² – 49 = 0 is 196.

Find the exact length of the third side

Mumz [18]

Answer:

Step-by-step explanation:

We know that 13 is the hypotenuse. With this we can use the Pythagorean Theorem to solve this problem.

Let the third side be x.

13^2=12^2+x^2

169=144+x^2

169-144=x^2

25=x^2

x=5

Help me plzz show work plz

iren2701 [21]

Answer:

Step-by-step explanation:

Use the formula for radius and circle circumference.

$d=2r \\ \\ C=2\pi r$

Since we know the diameter, if we divide that by 2, we can get the radius.

$29.5/2=14.75$

Now we can plug that value into the circumference formula to get the circumference.

$C=2(14.75)\pi \\ \\ C=29.5\pi \\ \\ C=93$

*Since we're rounding to the nearest inch.
