Answer:
Option B.
Step-by-step explanation:
The given quadratic equation is

We need to find the solution of given quadratic equation.
Divide both sides by 9.


Taking square root on both sides.


The solution of given equation are
and
.
Therefore, the correct option is B.
You substitute the y from the second eqaution to the y in the first equation
Answer:
Step-by-step explanation:
This kinda looks like the limiting definition of a derivative.
Anyway, what we are doing with the f(2 + h) is evaluating f(x) with 2+h in place for x. That looks like this:
f(2 + h) = 2(2 + h) - 3 which simplifies to
f(2 + h) = 4 + 2h - 3 which simplifies to
2h + 1
From that we are subtracting f(2). What we are doing with that is evaluating f(x) with 2 in place for x. That looks like this:
f(2) = 2(2) - 3 which simplifies to
f(2) = 4 - 3 which simplifies to
f(2) = 1. Now put those together over h to get:

We know, Force = mass × acceleration
( i ) :
Given,
Force = 25 units
Mass = 10 units
Acceleration = ?
Solution,
Applying the formula of force,
➡ Force = mass × Acceleration
⏩ 25 = 10 × acceleration
⏩ 25 / 10 =acceleration
⏩ 2.5 units = acceleration
( ii ) :
Given,
Force = 25 units
Acceleration = 5 units
Mass =?
Solution :
Applying formula,
➡ Force = mass × acceleration
⏩ 25 = 5 × mass
⏩ 25 / 5 = mass
⏩ 5 units = mass
