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.

Answer:

B) 1693.3

Step-by-step explanation:

Volume of a cylinder:

V = πr²h

V = π7²(11)

V = 49(11)π

V = 539π

V = 1693.3

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:

the answer is 1/81 I believe

Step-by-step explanation:

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

Hope this helps; have a great day!

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: 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:

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]

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:

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:

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:

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:

Step-by-step explanation:

Answer:

Steps:

given:

A = 235.2 m²

S1 = 2.8 m

S2 = A/S1

S2 = 235.2/2.8

S2 = 84 m

P = 2(S1+S2)

P = 2(2.8+84)

P = 2 × 86.8

P = 173.6 m
