Answer:

  -4arccos(x^(1/4)) +C

Step-by-step explanation:

My machine solver gives an answer that reduces to the expression ...

  -4arccos(x^(1/4)) +C

__

We know that ...

  (d/dx)arccos(x) = -1/√(1-x²)

If you let u = x^(1/4), then you can make the integrand look something like ...

  4 du/√(1 -u²)

which is what you need to get to the arccos function.

What are the rules to remember while working with Proportional Relationships?

Answers

Answer:

Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x ." This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

What is an equation of the line that passes through the point (2,−5) and is parallel to the line 6x+y=6

Answers

Answer:

[tex]y=-6x+7[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines always have the same slopes and different y-intercepts

1) Determine the slope (m)

[tex]6x+y=6[/tex]

Rewrite this in slope-intercept form (to help us find the slope)

Subtract 6x from both sides

[tex]6x+y-6x=-6x+6\\y=-6x+6[/tex]

Now, we can identify clearly that the slope of this line is -6. Because parallel lines always have the same slopes, -6 will therefore be the slope of the line we're solving for. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-6x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-6x+b[/tex]

Plug in the given point (2,−5) and isolate b

[tex]-5=-6(2)+b\\-5=-12+b[/tex]

Add 12 to both sides

[tex]-5+12=-12+b+12\\7=b[/tex]

Therefore, the y-intercept is 7. Plug this back into [tex]y=-6x+b[/tex]:

[tex]y=-6x+7[/tex]

I hope this helps!

Answer:

44.1

Step-by-step explanation:

Cosine = Adjacent over Hypotenuse

Adjacent of ∠T = 28 and hypotenuse = 39

Which means that  [tex]cos(x)=\frac{28}{39}[/tex]

Now we solve for x

To get rid of the "cos" we take the inverse of cos ( which is [tex]cos^-^1[/tex] ) and apply it to each side

[tex]cos^-^1((cos)x) = x\\cos^-^1(\frac{28}{39} )=44.11461855[/tex]

We're left with x = 44.11461855

Our last step is to round to the nearest tenth and we get that the answer is 44.1

if the replacement set is the set of integers, find the solution set for the inequality:
x - 9 < -15

a){-8, -7, -6, ...}

b){-9, -8, -7,...}

c){......, -8, -7, -6}

d){....., -9, -8, -7}

Answers

Answer:

c.    {....., -8, -7, -6}

Step-by-step explanation:

x - 9 < -15

x < -6

The value of x must be less than -6. From the set of values, the values less than -6 are -7, -8, -9.... The correct sets is {......,-8, -7, -6}

Given the inequality expression

x - 9 < -15

Add 9 to both sides

x - 9 + 9< -15 + 9

x + 0 < -15 + 9

x < -15 + 9

x < -6

Hence the value of x must be less than -6. From the set of values, the values less than -6 are -7, -8, -9.... The correct sets are {......,-8, -7, -6}

The can shown has a diameter of 3 inches and a height of 5 inches. Find the lateral surface area of the can.

Answers

Answer:

Lateral surface area of can = 47 inch² (Approx.)

Step-by-step explanation:

Given:

Diameter of given can = 3 inches

Height of given can = 5 inches

Find:

Lateral surface area of can

Computation:

Radius of can = 3 / 2 = 1.5 inch

Lateral surface area of can = Lateral surface area of cylinder

Lateral surface area of cylinder = 2πrh

Lateral surface area of can = 2πrh

Lateral surface area of can = 2(3.14)(1.5)(5)

Lateral surface area of can = 47.1

Lateral surface area of can = 47 inch² (Approx.)

The ratio of the corresponding sides is equal. Then the triangle ΔSTU is similar to the triangle ΔWVU which is ΔWVU ~ΔSTU.

What is the triangle?

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

Against Basic Proportionality Theorem: A line is similar to a third side if it divides any two aspects of a triangle with the same fraction.

The ratio of the sides is given as,

SU / UW = 9 / 6

SU / UW = 1.5

TU / UV = 6 / 4

TU / UV = 1.5

The ratio of the corresponding sides is equal. Then the triangle ΔSTU is similar to the triangle ΔWVU which is ΔWVU ~ΔSTU.
