Answer:
8
Step-by-step explanation:
To find the discriminant, we need to get the equation in standard form
9x^2+2=10x^2
Subtract 10x^2 from each side
9x^2-10x^2+2=10x^2-10x^2
-x^2 +2 =0
This is in the form ax^2+bx +c =0
where a=-1 b=0 and c=2
The discriminant is
b^2 -4ac
0^2 -4*(-1)*2
0+8
The discriminant is 8
Answer:
10.659 has 5 significant figures.
Step-by-step explanation:
Any number that is not 0 is a significant figure. There are 4 numbers that are not 0. Then, any 0 that is between two non-zero numbers is significant. The 0 is this number is between 1 and 6, so it is significant. Therefore, all the digits in this number are significant.
Input (x) while output (y)
Plug it into the equation
1. y = 2/2 + 1. Output = 2
2. y = 4/2 + 1 Output = 3
3. y = 7/2 + 1 output = 4.5
4. y = 9/2 + 1 Output = 5.5
