Answer: I believe it is

Step-by-step explanation: if you add 3x + 3x you get 6x. You would then add the like terms which are x + x ( x is equal to one) and that to 6x and you get 8x then add 2+2=4 and you get 8x + 4

Answer:

[tex] \displaystyle \sin(x) + x\cos( \alpha ) + \rm C[/tex]

Step-by-step explanation:

we are given

[tex] \displaystyle \int \frac{ \cos ^{2} (x) - \cos ^{2} ( \alpha ) }{ \cos( x) - \cos( \alpha ) } dx[/tex]

we want to Integrate it

notice that, the denominator can be rewritten by using algebraic identity

remember that,

[tex] \displaystyle {a}^{2} - {b}^{2} = ( a + b)(a - b)[/tex]

therefore

rewrite the denominator by using the identity:

[tex] \displaystyle \int \frac{ ((\cos (x) + \cos ( \alpha) ) ( \cos(x) - \cos( \alpha ) ) }{ \cos( x) - \cos( \alpha ) }dx [/tex]

reduce fraction:

[tex] \displaystyle \int \frac{ ((\cos (x) + \cos ( \alpha) ) ( \cancel{ \cos(x) -\cos( \alpha ) ) }}{ \cancel{\cos( x) - \cos( \alpha ) } }dx[/tex]

[tex] \displaystyle \int \cos(x) + \cos( \alpha ) dx[/tex]

recall that,

[tex] \rm\displaystyle \int f(x) \pm g(x)dx =\int f(x) \pm \int g(x)dx[/tex]

by that

we get

[tex] \displaystyle \int \cos(x) dx + \int \cos( \alpha )dx [/tex]

we also know that,

[tex] \displaystyle \int \cos(x) = \sin(x)dx [/tex]

and also the Integration of a constant is always cx

so,

[tex] \displaystyle \sin(x) + x\cos( \alpha ) [/tex]

and of course we have to add constant

[tex] \displaystyle \sin(x) + x\cos( \alpha ) + \rm C[/tex]

Step-by-step explanation:

This is based on the information provided: 2121.80 (1.03)2 = 2000 So, on your initial deposit of 2000, you can collect 121.80 in interest after two years.

Answer:

1. 2, 2. 1,  3. 5/4

Step-by-step explanation:

slope formula = [tex]\frac{y2 - y1}{x2 - x1}[/tex]

1. 0 - 4/0 - 2 = 2

2. 1 - 4/1 - 4 = 1

3. -2 - 3/-3 - 1 = 5/4

Answer:

The volume of this rectangular prism is 225 sqaure centimeters.

Step-by-step explanation:

The formula for finding volume is V = length * width * height

Substitute values in the formula:

5 * 15 * 3 = V

5 * 15 * 3 = 225

Answer:

$2,821.51

Step-by-step explanation:

The amount made be plumber = $51,482

rate of income tax = 5.5%

Therefore, amount of income tax in dollars and cents that would be paid by the plumber would be 5.5% of his amount made

= 5.5% of 51482

= (5.5/100)×51,482

= $2,821.51

Answer:

ML/OP=MK/PN since sides of similar traingle are proportional

17/60=35/PN

PN=35×60/17=123.529=123.6 or 124

The measure of the side PN is 123.5.

Similar triangles are those triangles which has the same shape but different size.

The length of sides and angles are proportional in similar triangles

Given that triangle KLM is similar to triangle NOP.

If two triangles are similar, then their corresponding sides will be proportional.

From the figure,

Corresponding side of LM is PO.

Corresponding side of MK is NP.

Corresponding side of LK is ON.

So LM / PO = MK / NP = LK / ON

17 / 60 = 35 / PN = LK / ON

We need the length of PN.

17 / 60 = 35 / PN

17 × PN = 60 × 35

PN = (60 × 35) / 17

PN = 123.5

Hence the measure of the side of the triangle is PN = 123.5.

Given:

Radius of the cylinder = 2 cm

Height of the cylinder = 3 cm

To find:

The surface area of the cylinder.

Solution:

The surface area of a cylinder is:

[tex]A=2\pi rh+2\pi r^2[/tex]

Where, r is the radius and h is the height of the cylinder.

Putting [tex]r=2,h=3,\pi = 3.14[/tex], we get

[tex]A=2(3.14)(2)(3)+2(3.14)(2)^2[/tex]

[tex]A=37.68+25.12[/tex]

[tex]A=62.8[/tex]

Therefore, the surface area of the cylinder is 62.8 square cm.

Answer:

area = 32 units²

Step-by-step explanation:

area = (4 x 10 x 0.5) + (2 x 2) + (2 x 2 x 0.5) + (6 x 2 x 0.5) = 32 units²

Answer:

a) 7.48 m²

b) 1.54 m³

Step-by-step explanation:

a) ¿Cuánta chapa se necesita para construir un tanque cilíndrico cerrado con un radio de base de 0.7 my una altura de 1 metro?

Debemos calcular el área de superficie de un tanque cilíndrico cerrado

radio = 0.7 m

Altura = 1 m

La fórmula = 2πr (h + r)

Por eso,

= 2 × π × 0.7 (0.7 + 1)

= 7.47699 m²

Aproximadamente = 7.48m²

b) Debemos encontrar la capacidad del cilindro en m³

Esto significa que debemos calcular el volumen del cilindro.

= π × r² × h

= π × 0.7² × 1

= 1.53938 m³

Aproximadamente = 1.54 m³
