Answer:
D = 141
Step-by-step explanation:
The given quadratic equation is
.
It is required to find the value of the discriminant. The value of discriminant of any quadratic equation is given by :

Here, a = 5, b = 9 and c = -3
On plugging all the values, we get :

So, the value of discriminant for y is 141.
Step-by-step explanation:
Force = pressure * area
= 200 * 3.7
= 740 N
Answer:
x=16
Step-by-step explanation:
y = 1/2 x -3
Let y =5
5 = 1/2 x -3
Add 3 to each side
5+3 = 1/2 x -3+3
8 = 1/2x
Multiply each side by 2
8*2 = 1/2x*2
16 =x
