Make n the subject of m= n² + 3
1 answer:
The n subject of m = n² + 3 is
How is n made the subject of m = n² + 3 ?
m = n² + 3
n² = m- 3
What does making n the subject mean?
- To make n the subject of the formula or equation, we must rearrange the variables in the formula or equation to have a single variable n that is equivalent to the other variables in the formula.
- The equation is then rearranged such that each term containing n is placed on the same side of the equation.
- If n appears in several words, factorization might be necessary.
- Just one n needs to be displayed at the conclusion to make it the subject.
- The result of square rooting a number or variable as an inverse operation may be positive or negative.

Answer:
the red car is traveling at 102.44 ft/s along the road
Step-by-step explanation:
From the given information:
Let consider p be how far the car is up the road and q be how far the police is off the road.
Also, suppose that r is the distance between the police and the car.
Then, we can have a right triangle in which we can use the Pythagorean Theorem to calculate the r (distance between the cop and the car)
NOW,
p² + q² = r²
r² = 40² + 180²
r² = 1600 + 32400
r² = 34000
r =
r = 184.39
If we consider q' to be how fast the car is traveling down the road.
And, p' be how fast the police is traveling toward the road.
r' be how fast the distance between the police and the car is changing.
then , the derivative of our equation, p² + q² = r² with respect to time can now be:
2p(p') +2q(q') = 2r(r')
p(p') +q(q') = r(r')
By replacing our values; we have:
40(0) +180(y') = (given that the police is not moving p' =0)
180(y') =
the red car is traveling at 102.44 ft/s along the road
Answer:
(-3,-6)
(0,-5)
(3,-4)
(5,-3)
Step-by-step explanation:
Step 1: Have 'x' values selected(make it multiples of 3 so 'y' is a whole number)
-3, 0, 3, 6
Step 2: Substitute the x to solve for y
Step 3: State your answers
Therefore the ordered pairs are:
(-3,-6)
(0,-5)
(3,-4)
(5,-3)
