Answer:

25

Step-by-step explanation:

because if you do 1000 divided buy 25 its 69420 so if you do 69420 divided by 69420 its 1 and 1x1000 its 1000 divided by 54 its 25 so its 25

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:

B) 1693.3

Step-by-step explanation:

V = 539π

V = 1693.3

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: 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:

B- Parallelogram PQRS is also a rhombus.

Step-by-step explanation:

Given

Parallelogram PQRS with perpendicular diagonals

Required

Which of the option is true

(a) PQRS can be a rectangle

A rectangle do not have perpendicular diagonals.

Hence, (a) is false

If (a) is false, then (d) is also false

(b) PQRS can a rhombus

The diagonals of a rhombus are not perpendicular.

So (b) is true

No need to check for (c), since only option is true

Answer:

B- Parallelogram PQRS is also a rhombus.

Answer:

1/6

Step-by-step explanation:

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:

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:

Step-by-step explanation:

Using the two points on the regression line, let's find its equation.

Points:

The slope:

The y-intercept is

The equation:

Solve for x if y = 90

The answer is 24 hours

Answer:

Slope  = 3

y intercept = -8

y = 3x  - 8

Step-by-step explanation:

From the table shown, we can make use of the coordinate points

(0, -8) and (1, -5)

Slope m = y2-y1/x2-x1

m = -5-(-8)/1-0

m = -5+8/1-0

m = 3/1

m = 3

Slope  = 3

The standard form of an equation is y = mx+b

b is the y intercept

Substitute m = 3 and (0, -8) into y = mx+b

-8 = 3(0) + b

-8 = b

b = -8

Hence y intercept is -8

Get the required equation

Recall that y = mx+b

y = 3x + (-8)

y = 3x  - 8

This gives the required equation

Answer:

The slope othe line is - 1

Answer:

-1/4

Step-by-step explanation:

Answer:Cost of dryer=$325

Step-by-step explanation:

Let the dryer  be represented as  x

and the washer be x+76

such that the price of both can be written as  

dryer + washer=$726

x + x+76=726

2x+76=726

2x=726-76

2x=650

x=650/2=325

Cost of dryer =x=$325

Answer:

The answer is D.

It's D because a expression is numbers grouped together not just 1 number. Hope it helps and have a blessed day.

Answer:

B

Step-by-step explanation:

B is an equation, not an expression

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:

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:

4/25 seconds

Step-by-step explanation:

the second (0.16) is in two decimal places, so divide 16 by 100

[tex]\frac{16}{100}[/tex]

to express in the simplest form, divide the numerator  and the denominator by 4

= [tex]\frac{4}{25}[/tex]

Step-by-step explanation:

z² +x² - y= -2²+ -1² - 3

4+ 1 - 3= 2

x²y²z²= -1²× 3²× -2²

1× 9× 4= 36

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
