E^3x.cos4x.sin2x hii please solv this you have to differentiate

finlep [7]

Answer:

$y = e^{3x}.cos4x.sin2x$

$=> y' =- 3e^{3x}.4sin4x.2cos2x=-24.e^{3x}.sin4x.cos2x$

$dy=y'.dx => dy = -24e^{3x}.sin4x.cos2x.dx$

One institute mandates that for every 100 items scanned through the electronic checkout scanner at a retail store, no more than

ozzi

Answer:

There is a 20% probability that the store selected does not violate the institute scanner accuracy standard

Step-by-step explanation:

70 company stores were investigared.

56 violated the institute's scanner accuracy standard.

70-56 = 14 did not violate the institute scanner accuracy standard.

If 1 of the 70 company stores is randomly selected, what is the probability that that store does not violate the institute scanner accuracy standard?

This is 14 divided by 70, so:

$P = \frac{14}{70} = 0.2$

There is a 20% probability that the store selected does not violate the institute scanner accuracy standard

Answer:

3) Midpoint is (-4,0.5)

Option A is correct.

4) Midpoint is (2.5,0)

Option B is correct.

5) The factors are (x+4)(x-7)

Option C is correct.

6) The factors are (x+4)(x+2)

Option A is correct.

Step-by-step explanation:

Question 3

Find midpoint of the following:

(2,-7), (-10,8)

The formula used to find midpoint is: $Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$

We have $x_1=2, y_1=-7, x_2=-10,y_2=8$

Putting values and finding midpoint

$Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )\\Midpoint=(\frac{2-10}{2},\frac{-7+8}{2} )\\Midpoint=(\frac{-8}{2},\frac{1}{2} )\\Midpoint=(-4,0.5 )$
