Answer:

area = 520 units²

Step-by-step explanation:

divide the hexagon into 6 equal triangles.

each triangle has a base of 14 and a height of 12.1 so:

the area of one triangles = 1/2BH = 1/2(14)(12.1) = 86.8 units ²

86.8 x 6 triangles = 520.8 units²

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]

Answer:

80°

Step-by-step explanation:

If the intercepted arc is 80°, the angle has to be 80°

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

Hildie can type 74 words per MINUTE. And we know she typed for 45 minute, so we can just multiply 74 and 45.

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.

Answer:

21.21

Step-by-step explanation:

Area of a circle is A = π r^2

Variables:

r = 18/2 = 9

θ = 30 deg

Find the area:

A = π r^2

A = π 9^2

A = 254.47

Find the area of the sector:

θ/360 * A

= 30/360 * 254.47

= 21.21

Answer:

Option (2)

Step-by-step explanation:

By the property of triangle,

If the sides of triangle are unequal, then the ratio of the measures of the angles will be equal to the ratio of their opposite sides.

Following this rule,

Angle opposite to the largest side will be biggest and angle opposite to the smallest side will be smallest.

Since, LJ > KL > JK

Therefore,

∠K > ∠J > ∠L

Option (2) will be the answer.

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

Answer:

68°

Step-by-step explanation:

The formula for arc length when central angle is in degrees =

Arc length = 2πr × θ /360

Arc length = 68/15π

Radius = the length of PC = 12 units

Hence:

68/15π = 68π/15 = 2 × π × 12 × θ /360

68π/15 = 75.4 ×θ /360

Cross Multiply

68π × 360 = 15 × 75.4 × θ

θ = 68π × 360/15 × 75.4

= 67.998398019°

Approximately = 68°

Therefore, the measure of central angle = 68°

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:

-(2/3)x+4

Step-by-step explanation:

For the slope you do rise over run, since the graph intercepts the y-axis at 4 and goes down to 0 the rise is -4 and from the same point the graph "runs" 6 the rise/run is -4/6 which can be simplified to -2/3. For the y-intercept you simply find where the graph touches the y-intercept and add (or subtract if the number is negative) that to the end of the equation.
