Answer:

I think its -4.

Answer:

The terminal side of angle will lie in thirds quadrant

Step-by-step explanation:

Given the angle is 28.3 degree radians

Converting it into degrees we get -

28.3rad × 180/π = 1621.471°

Total 360 degrees rotation in this angle

1621.471°/360 = 4

SO the remaining degrees 181.471

The angle grater than 180 lies in third quadrant.

The terminal side of angle will lie in thirds quadrant

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:

The ratio between men and children is 4:3.

Step-by-step explanation:

Since in a ferry, the ratio of the number of woman to the number of man is 3: 2 and the ratio of the number of woman to the number of children is 2: 1, to find the ratio of the number of man to the number of woman to the number of children in the ferry, the following calculation must be performed:

3 women for every 2 men = 6 women for every 4 men (x 2)

2 women for every 1 child = 6 women for every 3 children (x 3)

6 women + 4 men + 3 children = 6: 4: 3

Thus, the ratio between men and children is 4:3.

Answer:

Options C and D are the correct options.

Step-by-step explanation:

Option A

cos(H) = 0.3846

By applying cosine rule in ΔFGH,

cos(H) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

           = [tex]\frac{36}{39}[/tex]

           = 0.9231

False

Option B

cos(G) = 0.9231

By applying cosine rule in ΔFGH,

cos(G) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

           = [tex]\frac{15}{39}[/tex]

           = 0.3846

False

Option C

sinG = 0.9231

By applying sine rule in ΔFGH,

sin(G) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

          = [tex]\frac{36}{39}[/tex]

          = 0.9231

True

Option D

tanG = 2.4

By applying tangent rule in ΔFGH,

tanG = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

        = [tex]\frac{36}{15}[/tex]

        = 2.4

True

Therefore, Options C and D are the correct options.

Answer: 2/5

Step-by-step explanation:

Number of cans of red paint = 3

Number of cans of blue paint = 5

Number of cans of green paint = 8

Number of cans of yellow paint = 4

Total number of cans of paint = 20

The probability that Eduardo will

choose a can of red paint or a can of blue will be:

= P(red) + P(blue)

= 3/20 + 5/20

= 8/20

= 2/5

The probability is 2/5.

Answer:

The correct answer is; Ann was on the call for 41 minutes.

Step-by-step explanation:

20-14.26 is equivalent to 5.74, in which you divide that by .14 (fourteen cents) and get 41.

Answer:

$636

dont trust me im just a 7th grader

Answer:

Number 7 is 25%

Step-by-step explanation:

You take the original price and subtract it by each percentage until you get 30.

$40.00 - 15% = 34

$40.00 - 20% = 32

$40.00 - 40% = 24

$40.00 - 25% = 30

Therefore, the answer is 25% !

Hoped this helped you! :D

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:

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:

I am pretty sure the answer is  64

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]
