Answer:

The sine of the angle = the length of the opposite side. the length of the hypotenuse.

The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.

The tangent of the angle = the length of the opposite side. the length of the adjacent side.

What is the discriminant of 3x2 + 6x = 2?

Softa [21]

Answer:

Discriminant is 60

Step-by-step explanation:

the discriminant of $3x^2 + 6x = 2$

To find discriminant , first we write the equation in the form of

$ax^2+bx+c=0$

$3x^2 + 6x = 2$

Subtract 2 on both sides

$3x^2 + 6x-2=0$

a=3, b=6, c=-2

Formula for discriminant is $b^2-4ac$

Plug in the values

$b^2-4ac=(6)^2-4(3)(-2)=60$

Discriminant is 60

The formula for finding the perimeter of a rectangle with length, l, and width, w, is P = 2l + 2w.

user100 [1]

Perimeter of a rectangle:
P=2I+2W=2(I+w)

But if the length and width of a rectangle are both double, then we would have:
Length=2I
width=2w

Therefore, its perimeter would be:
P=2(2I+2w)=4(I+w)

the old perimeter was P=2(I+w) and the new perimeter is P=4(I+w)=2[2(l+w)]
There the perimeter is twice as great.

Answer: C) the perimeter is twice as great.
