Find an equation for a line that is normal to the graph of y=xe^x and goes through the origin
Marina CMI [18]
Y = xe^x
dy/dx(e^x x)=>use the product rule, d/dx(u v) = v*(du)/(dx)+u*(dv)/(dx), where u = e^x and v = x:
= e^x (d/dx(x))+x (d/dx(e^x))
y' = e^x x+ e^x
y'(0) = 1 => slope of the tangent
slope of the normal = -1
y - 0 = -1(x - 0)
y = -x => normal at origin

The test to detect the presence of a certain protein is 98% accurate for corn plants that have the protein and 97% accurate for
larisa [96]

Using the given percentages, it is found that the probability that a randomly chosen plant is detected incorrectly is 0.02965 = 2.965%.

<h3>Percentages:</h3>

The percentages associated with an incorrect detection are:

  • 2% of 3.5%(have the protein).
  • 3% of 96.5%(do not have the protein).

Hence:

p = 0.02(0.035) + 0.03(0.965) = 0.02965

The probability that a randomly chosen plant is detected incorrectly is 0.02965 = 2.965%.

3.6 - 2 - 3 = 4x - 8<br> please helppp
chubhunter [2.5K]

Answer:

x=1.65

Step-by-step explanation:

First switch sides

4x-8=3.6-2-3

Then subtract 3.6 - 2 - 3

4x-8=-1.4

Add 8 to both sides

4x-8+8=-1.4+8

simplify

4x=6.6

Divide both sides by 4

4x/4 - 6.6/4

The simplify again

x=1.65

What is 3x + 5y ????
baherus [9]
3x + 5y
Equal it out to zero.
3x + 5y = 0
Lets solve for x first.
3x = -5y
Divide by 3 to get x by itself.
x = -5y/3
Now solve for y.
3x + 5y = 0
Add -3 to both sides.
5y = -3x
Divide both sides by 5.
y = -3/5x

I Sure Hope This Helps!
