Find the equation of the normal to the curve y=x^2-2x^2-4x+1 at thepoint (-1,2)

balandron [24]

Answer:

$y=-\frac{1}{3}x+\frac{5}{3}$

Step-by-step explanation:

Assuming that the first exponent in the formula for the curve should be 3, not 2...

$y=x^3-2x^2-4x+1$

The derivative is

$y'=3x^2-4x+4$

The slope of the tangent line at the point (-1, 2) is the value of the derivative at x = -1.

$y'|_{x=-1} = 3(-1)^2-4(-1)+4=3-4+4=3$

The slope of the normal line is the opposite reciprocal of the slope of the tangent line.

$m_{\text{normal} = -\frac{1}{3}$

Using the Point-Slope form of a linear equation, the normal line is

$y-2=-\frac{1}{3}(x-(-1))\\y-2=-\frac{1}{3}(x+1)\\y=-\frac{1}{3}x-\frac{1}{3}+2\\y=-\frac{1}{3}x+\frac{5}{3}$

If 97 of 200 is 100% then how much of 200 is 112%

pickupchik [31]

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 112 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 112 is 100%, so we can write it down as 112=100%.
4. We know, that x is 200% of the output value, so we can write it down as x=200%.
5. Now we have two simple equations:
1) 112=100%
2) x=200%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
112/x=100%/200%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 200% of 112

112/x=100/200
(112/x)*x=(100/200)*x - we multiply both sides of the equation by x
112=0.5*x - we divide both sides of the equation by (0.5) to get x
112/0.5=x
224=x
x=224

now we have:
200% of 112=224

Answer:

D. Expression for Nick's distance from starting point= 6+(-4)+2

Step-by-step explanation:

Finding expression for each scenario:

A.

Number of boxes processed on on Monday =6 boxes

Number of boxes processed on on Tuesday =4 boxes

Number of boxes processed on on Wednesday =2 boxes

Expression for total boxes processed on these 3 days = $6+4+2$

B.

Temperature of Suma's city at noon = 6°C

Temperature of Suma's city at 8pm = 4°C

Temperature of Suma's city at noon next day = 2°F

Total temperature change = cannot be determined as all measurements are not in same units.

C

Money put on Monday = $6

Money put in Wednesday =$4

Money withdrew on Saturday = $2

Expression for balance of Re'onna's piggy bank = $6+4-2$

D

Distance ran north =6 miles

Distance ran south(back) = 4 miles

Distance ran north again = 2 miles

Expression for Nick's distance from starting point= 6+(-4)+2
