Answer:

[tex]y = e^{3x}.cos4x.sin2x[/tex]

[tex]=> y' =- 3e^{3x}.4sin4x.2cos2x=-24.e^{3x}.sin4x.cos2x[/tex]

[tex]dy=y'.dx => dy = -24e^{3x}.sin4x.cos2x.dx[/tex]

Step-by-step explanation:

The function [tex]e^3^x[/tex].cos4x.sin2x on differentiating gives the solution as 2[tex]e^3^x[/tex]cos2x.cos4x - 4[tex]e^3^x[/tex]sin2x.sin4x + 3[tex]e^3^x[/tex]cos4x.sin2x.

Product rule in differentiation states that, for two functions f(x) and g(x),

[tex]\frac{d}{dx}[/tex] [f(x).g(x)] = f(x) . [tex]\frac{d}{dx}[/tex][g(x)] + g(x) . [tex]\frac{d}{dx}[/tex][f(x)]

The question is to differentiate y = [tex]e^3^x[/tex].cos4x.sin2x

We have three functions here.

Let u = [tex]e^3^x[/tex] and v = cos4x.sin2x

[tex]\frac{d}{dx}[/tex] [u . v] = u [tex]\frac{d}{dx}[/tex][v] + v [tex]\frac{d}{dx}[/tex][u]

             = [tex]e^3^x[/tex] [tex]\frac{d}{dx}[/tex] [cos4x.sin2x] + cos4x.sin2x [tex]\frac{d}{dx}[/tex] [[tex]e^3^x[/tex] ]

             = [tex]e^3^x[/tex] [tex]\frac{d}{dx}[/tex] [cos4x.sin2x] + cos4x.sin2x (3[tex]e^3^x[/tex])

[tex]\frac{d}{dx}[/tex] [u . v] =  [tex]e^3^x[/tex] [tex]\frac{d}{dx}[/tex] [cos4x.sin2x] + 3[tex]e^3^x[/tex]cos4x.sin2x

Let the above equation be equation E.

Again apply the product rule for [tex]\frac{d}{dx}[/tex] [cos4x.sin2x].

Let u' = cos4x and v' = sin2x

[tex]\frac{d}{dx}[/tex] [u'. v'] = u' [tex]\frac{d}{dx}[/tex][v'] + v' [tex]\frac{d}{dx}[/tex][u']

            = cos4x [tex]\frac{d}{dx}[/tex][sin2x] + sin2x [tex]\frac{d}{dx}[/tex][cos4x]

            = cos4x [2cos2x] + sin2x [-4sin4x]

            = 2cos2x.cos4x - 4sin2x.sin4x

Substituting this is equation E, we get,

[tex]\frac{d}{dx}[/tex] [u . v] =  [tex]e^3^x[/tex] [2cos2x.cos4x - 4sin2x.sin4x] + 3[tex]e^3^x[/tex]cos4x.sin2x

             =  2[tex]e^3^x[/tex]cos2x.cos4x - 4[tex]e^3^x[/tex]sin2x.sin4x + 3[tex]e^3^x[/tex]cos4x.sin2x

Hence the function [tex]e^3^x[/tex].cos4x.sin2x on differentiating gives 2[tex]e^3^x[/tex]cos2x.cos4x - 4[tex]e^3^x[/tex]sin2x.sin4x + 3[tex]e^3^x[/tex]cos4x.sin2x.

Answer:

32 square units

Step-by-step explanation:

You can split this shape into four different shapes:

2 unit by 2 unit triangle

2 unit by 2 unit square

2 unit by 6 unit triangle

To find the length of the big triangle, add the lengths of the small triangle,the square,and the bigger leg of the other triangle:

2 + 2 + 6 = 10

10 unit by 4 unit triangle

Then solve all these areas:

( 2 x 2 ) / 2 = 4 / 2 = 2

2 x 2 = 4

( 2 x 6 ) / 2 = 12 / 2 = 6

( 10 x 4 ) / 2 = 40 / 2 = 20

Then add all these areas together to get the total area of the composite shape:

2 + 4 + 6 + 20 = 32

Answer:

Answer:

slope = -4

Step-by-step explanation:

3y = 9 - 12x

Rearrange the right-hand side:

3y = - 12x + 9

Next, Divide both sides by 3 to isolate y:

[tex]\frac{3y}{3} = \frac{-12x + 9}{3}[/tex]

y = -4x +3 this is the slope-intercept form where the slope, m = -4, and the y-intercept, b = 3.

Therefore, the slope = -4.

[tex]18 + ( - 30) = 18 - 30 = - 12[/tex]

I hope I helped you^_^

Step-by-step explanation:

we need to find the slope of each line.

the slope is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.

parallel lines have the same slope.

for a perpendicular line x and y in the slope ratio are put upside down, and the sign is flipped (+ to - and vice versa).

a.

2x - 8y = -24

2x + 24 = 8y

y = 2/8 x + 24/8 = 1/4 x + 3

the slope is 1/4 (always the factor of x).

4x + y = -2

y = -4x - 2

the slope is -4 = -4/1.

this line is therefore perpendicular to the first line.

x - 4y = 4

x - 4 = 4y

y = 1/4 x - 4/4 = 1/4 x - 1

the slope is 1/4.

this line is therefore parallel to the first line.

b.

3x - 9y = 9

9y = 3x - 9

y = 3/9 x - 9/9 = 1/3 x - 1

the slope is 1/3

3y = x + 12

y = 1/3 x + 4

the slope is 1/3.

this line is therefore parallel to the first line.

2x - 6y = 12

6y = 2x - 12

y = 2/6 x - 12/6 = 1/3 x - 2

the slope is 1/3.

this line is therefore parallel to the first line.

Answer:the anwser is 4

Step-by-step explanation:

Step-by-step explanation:

a fence represents the circumference, the perimeter of the lot or yard.

remember, a rectangle has 2 parallel sides called the length, and 2 parallel sides called the width (altogether 4 sides).

therefore

perimeter = 2×length + 2×width

or with short variables

p = 2×l + 2×w

so, now we have 50 ft of fence available for the perimeter. and the length l = 13 ft.

since we have 2 lengths in the perimeter, these 13 ft are twice (2×13 = 26 ft) in the perimeter.

now, how much fence do we have left for the width ?

well, 50 - 26 = 24 ft

and again, this is the size of 2 sides (2×width) :

p = 2×l + 2×w

50 = 2×13 + 2×w = 26 + 2×w

2×w = 24

w = 12 ft

so, the width of the yard must not be bigger than 12 ft.

Answer:  65 degrees

Explanation:

The adjacent angle directly above angle 8 is congruent to the 115 degree angle (due to the corresponding angles theorem). This only works because p || q and q || r, so by the transitive property of parallel lines, we know that p || r.

Since the 115 degree angle and angle 8 pair up to form a straight line, we know that the two angles must add to 180 degrees

115+(angle 8) = 180

angle 8 = 180 - 115

angle 8 = 65 degrees

Answer:

[tex]m[/tex]∠8 = 65°

Step-by-step explanation:

The other side (angle) of 115 is [tex]n[/tex] and [tex]n =[/tex] ∠8

To find [tex]n[/tex] you need to subtract 180 - 115 giving you 65, and since n is angle 8, angle 8 is also 65 since the angles have a state of congruence...
