find the equations of the tangents to the curve y= x(x-1)(x+2) at the points where the curve cuts the x axis
antoniya [11.8K]

First of all, we compute the points of interest, i.e. the points where the curve cuts the x axis: since the expression is already factored, we have

x(x-1)(x+2) = 0 \iff x=0\ \lor\ x-1=0\ \lor\ x+2=0

Which means that the roots are

x=0\ \lor\ x=1\ \lor\ x=-2

Next, we can expand the function definition:

y = x(x-1)(x+2) = x^3 + x^2 - 2x

In this form, it is much easier to compute the derivative:

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

If we evaluate the derivative in the points of interest, we have

y'(-2) = 6,\quad y'(0)=-2,\quad y'(1)=3

This means that we are looking for the equations of three lines, of which we know a point and the slope. The equation

y-y_0=m(x-x_0)

is what we need. The three lines are:

y-0=6(x+2) \iff y = 6x+12  This is the tangent at x = -2

y-0=-2(x-0) \iff y = -2x  This is the tangent at x = 0

y-0=3(x-1) \iff y = 3x-3  This is the tangent at x = 1

16. Find the value of y. ​
devlian [24]

y + (2x -12) = 180 (since they are supplementary angles)

(2x-12) = 96 ( since they are alternate exterior angle)

2x = 96 + 12

2x = 108

x = 108/2

x = 54.

y+( 2x-12)=180

y+(2× 54 -12) = 180

y + (108-12) = 180

y + 96 = 180

y= 180-96

y = 84.

If 100 treats will feed 15 dogs (each dog is given the same number of treats), how many dogs can be fed with 40 treats?
Lisa [10]

Answer: 6 dogs

Step-by-step explanation:

If 100 treats will feed 15 dogs, then that means that the number of treats that each dog requires is:

= 100/15

= 6.67 treats

If 6.67 treats will feed one dog then the number of dogs that will be fed by 40 is:

= 40 / 6.67

= 6 dogs

What is the Cost of $700 tablet computer that is on sale at 15% off of the local sales tax rate is 4%?
never [62]

Answer:

$618.80

Step-by-step explanation:

If the tablet is on sale for 15% off, you pay 85% of the original price.

85% of $700 is

700(0.85) = $595

You pay 4% sales tax on $595, which is

$595(0.04) = $23.80

The total cost you pay is $595 + $23.80 = $618.80
