What is the discriminant of 3x^2 - 10 = -2?

The formula for the discriminant is b^2-4ac. The formula you wote is in the form of 
ax^2+c=0, so first, you need to bring that -2 to the left. When you do that, you get (the original equation would be ax^2+bx+c but you have no bx.)

3x^2-8

So, since there's no b, it would be
b^2-4ac
0^2-4(3)(-8
-12 x -8
96

A ball dropped from the top of the building can be modeled by the function f(t)=-16t^2 + 36 , where t represents time in seconds after the ball was dropped. A bee's flight can be modeled by the function, g(t)=3t+4, where t represents time in seconds after the bee starts the flight.

If a/b=2 what is the value of 4b/a​
bazaltina [42]

Anwer:

4b/a=2

Step-by-step explanation:

Lets assume:

a = 4 & b = 2

So a/b would equal 2.

4b/a indicates that you are going to multiply b times 4, meaning that in this scenario you would multiply 2 times 4.

4(2) = 8

and 8 divided by (4) is 2.

Why 4? Because remember a = 4 (in this scenario).

Other examples:

10/5 = 2, -->  4(5) = 20, -->  20/10 = 2.

20/10 = 2. --> 4(10) = 40, --> 40/20 = 2.
