4(x-3)= -2(6-2x) solve equation

Answer:

  13.25 ft

Step-by-step explanation:

Let w represent the width of the window. Then w-5 represents the length, and the perimeter is ...

  P = 2(L+W)

  43 = 2((w-5) +w) = 4w -10

  53/4 = w = 13.25 . . . feet

The width of the window is 13.25 ft.

If you don't know the derivative of the inverse of sine, you can use implicit differentiation. Apply sine to both sides:

[tex]y=\sin^{-1}(6x+1)\implies\sin y=6x+1[/tex]

(true for y between -π/2 and π/2)

Now take the derivative of both sides and solve for it:

[tex]\cos y\dfrac{\mathrm dy}{\mathrm dx}=6[/tex]

[tex]\dfrac{\mathrm dy}{\mathrm dx}=6\sec y[/tex]

[tex]\dfrac{\mathrm dy}{\mathrm dx}=\dfrac6{\cos\left(\sin^{-1}(6x+1)\right)}[/tex]

[tex]\dfrac{\mathrm dy}{\mathrm dx}=\dfrac6{\sqrt{1-(6x+1)^2}}[/tex]

Answer:

[tex]8x+9<4[/tex] and [tex]8x+9>-4[/tex].

Step-by-step explanation:

The given inequality is

[tex]|8x+9|<4[/tex]

We need to rewrite the given inequality as two linear inequalities.

We know that |8x+9|>0 but (8x+9) can be positive or negative.

For [tex]|8x+9|<4[/tex],  the value of (8x+9) must be lies between -4 and 4.

i.e., [tex]-4<8x+9<4[/tex]

If 8x+9 positive, then

[tex]8x+9<4[/tex]      ...(1)

If 8x+9 negative, then

[tex]8x+9>-4[/tex]      ...(2)

Therefore, the two inequalities are [tex]8x+9<4[/tex] and [tex]8x+9>-4[/tex].

A graph of the data that was collected is shown: A line graph with Number of Months on the x axis and Number of Users, in thousands, on the y axis. The x axis has a scale from 0 to 36 with an increment of 4. The y axis has a scale of 0 to 60 with increments of 6. A straight line connecting 0, 0 and approximately 36, 54 is drawn. What can be interpreted from the range of this graph? v .

Answer:

c

Step-by-step explanation:

Answer:

26) Let the first number be x.

Sum of three consecutive even numbers:

[tex]x+(x+2)+(x+4)=-84[/tex]

[tex]x+x+2+x+4=-84\\[/tex]

[tex]3x+6=-84[/tex]

Subtract 6 from both sides:

[tex]3x+6-6=-84-6[/tex]

[tex]3x=-90[/tex]

Divide both sides by 3:

[tex]\frac{3x}{3}=\frac{-90}{3}[/tex]

[tex]x=-30[/tex]

To find the other two numbers, add 2 and 4 respectively:

[tex](-30+2=-28)(-30+4=-26)[/tex]

27) Let the first number be x.

Sum of three consecutive odd integers:

[tex]x+(x+2)+(x+4)=141[/tex]

[tex]3x+6=141[/tex]

Subtract 6 from both sides:

[tex]3x+6-6=141-6\\3x=135[/tex]

Divide both sides by 3:

[tex]\frac{3x}{3}=\frac{135}{3}\\x=45[/tex]

To find the other two numbers, add 2 and 4 respectively:

[tex](45+2=47)(45+4=49)[/tex]

28) Let the first number be x.

Sum of four consecutive integers:

[tex]x+(x+1)+(x+2)+(x+3)=54[/tex]

[tex]4x+6=54[/tex]

Subtract 6 from both sides:

[tex]4x+6-6=54-6\\4x=48[/tex]

Divide both sides by 4:

[tex]\frac{4x}{4}=\frac{48}{4}\\x=12[/tex]

To find the other three numbers, add 1, 2 and 3 respectively:

[tex](12+1=13)(12+2=14)(12+3=15)[/tex]

29) Let the first number be x.

Sum of four consecutive integers:

[tex]x+(x+1)+(x+2)+(x+3)=-142[/tex]

[tex]4x+6=-142\\[/tex]

Subtract 6 from both sides:

[tex]4x+6-6=-142-6[/tex]

[tex]4x=-148[/tex]

Divide both sides by 4:

[tex]\frac{4x}{4}=\frac{-148}{4}\\x=-37[/tex]

To find the other three numbers, add 1, 2 and 3 respectively:

[tex](-37+1=-36)(-37+2=-35)(-37+3=-34)[/tex]

[tex] \dashrightarrow{ \sf{216}}[/tex]

Finding the seats that are not occupied

[tex] \longrightarrow{ \sf{450 - 216 = 234}}[/tex]

Answer:

S = { (4), (5), (1,4), (1,5), (2,4), (2,5), (3,4), (3,5), (1,2,3,4), (1,2,3,5), (2,1,3,4) (2,1,3,5), (3,1,2,4), (3,1,2,5) }

A ={(4), (5)}

Step-by-step explanation:

Given that:

Among the three copies, (1,2,3) are the first printings, and (4,5) are the second printings.

A student who examines these books in random order stops when a second printing has been selected.

Thus, we can compute the sample space associated with these experiments as:

S = { (4), (5), (1,4), (1,5), (2,4), (2,5), (3,4), (3,5), (1,2,3,4), (1,2,3,5), (2,1,3,4) (2,1,3,5), (3,1,2,4), (3,1,2,5) }

Suppose A represents the event that we must examine exactly one book.

Then the outcomes of A are:

A ={(4), (5)}

Answer:

[tex]\displaystyle \frac{\cos x}{1 + \sin x} = \tan\left(\frac{\pi}{4} - \frac{x}{2}\right)[/tex].

Overview of the steps:

Step-by-step explanation:

Double-angle identity of sines and cosines:

Pythagorean identity for the sine and cosine of the same angle:

[tex]1 = \cos^2\alpha + \sin^2\alpha[/tex].

Angle sum and difference identity of sines and cosines:

[tex]\sin(\alpha - \beta) = \sin\alpha\, \cos\beta - \cos\alpha \, \sin\beta[/tex].

[tex]\cos(\alpha - \beta) = \cos\alpha\, \cos\beta + \sin\alpha \, \sin\beta[/tex].

Consider [tex]x[/tex] as the sum of two angles of size [tex](x/2)[/tex]. Start by applying the double-angle identity to the left-hand side.

[tex]\begin{aligned} \text{L.H.S.}&= \frac{\cos(x)}{1 + \sin(x)} \\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{1 + 2\, \sin(x / 2)\, \cos(x / 2)}\end{aligned}[/tex].

Apply the Pythagorean identity to rewrite the "1" in the denominator as [tex]\left(\cos^2(x / 2) + \sin^2(x / 2)\right)[/tex].

[tex]\begin{aligned} \text{L.H.S.}&= \frac{\cos(x)}{1 + \sin(x)} \\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{1 + 2\, \sin(x / 2)\, \cos(x / 2)}\\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{\sin^2(x/2) + 2\,\sin(x/2)\, \cos(x/2) + \cos^2 (x/2)}\end{aligned}[/tex].

Note that the denominator is now a perfect square. On the other hand, the numerator is in the form [tex](x^2 - y^2)[/tex], which is equal to [tex](x + y)\, (x - y)[/tex]. Rewrite and simplify this expression:

[tex]\begin{aligned} \text{L.H.S.}&= \frac{\cos(x)}{1 + \sin(x)} \\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{1 + 2\, \sin(x / 2)\, \cos(x / 2)}\\ &= \frac{\cos^2(x / 2) - \sin^2(x / 2)}{\sin^2(x/2) + 2\,\sin(x/2)\, \cos(x/2) + \cos^2 (x/2)} \\[1em] &= \frac{(\cos(x/2) + \sin(x/2))\, (\cos(x/2) - \sin(x/2))}{\left(\sin(x/2) + \cos(x/2)\right)^2} \\ &= \frac{\cos(x/2) - \sin(x/2)}{\sin(x/2) + \cos(x/2)}\end{aligned}[/tex].

The tangent of an angle is equal to the ratio between its sine and its cosine. Apply the angle sum and difference identity of sine and cosine to the right-hand side.

Note, that the sine and cosine of [tex](\pi/4)[/tex] are both equal to [tex]\left(\sqrt{2}/2\right)[/tex].

[tex]\begin{aligned}\text{R.H.S.} &= \tan\left(\frac{\pi}{4} - \frac{x}{2}\right) \\ &= \frac{\sin((\pi/4) - (x/2))}{\cos((\pi/4) - (x/2))}\\ &= \frac{\left(\sqrt{2}/2\right)\, \cos(x/2) - \left(\sqrt{2}/2\right)\, \sin(x/2)}{\left(\sqrt{2}/2\right)\, \cos(x/2) + \left(\sqrt{2}/2\right)\, \sin(x/2)} \\ &= \frac{\cos(x/2) - \sin(x/2)}{\cos(x/2) + \sin(x/2)}\end{aligned}[/tex].

Therefore:

[tex]\displaystyle \text{L.H.S.} = \frac{\cos(x/2) - \sin(x/2)}{\sin(x/2) + \cos(x/2)} =\text{R.H.S.}[/tex].

[tex]\displaystyle \frac{\cos x}{1 + \sin x} = \tan\left(\frac{\pi}{4} - \frac{x}{2}\right)[/tex].

Answer:

D. 3

Step-by-step explanation:

We can see from the graph that there are 3 lines. All 3 lines look linear, and if a line is linear, x and y are proportional. Therefore, if all 3 lines are linear, then we have 3 proportional relationships.

Answer:

[tex]a=2K-b[/tex]

Step-by-step explanation:

[tex]K=\frac{a+b}{2}[/tex]

Switch sides:

[tex]\frac{a+b}{2}=K[/tex]

Multiply both sides by 2:

[tex]\frac{2\left(a+b\right)}{2}=2K[/tex]

[tex]a+b=2K[/tex]

Subtract b from both sides:

[tex]a+b-b=2K-b[/tex]

[tex]a=2K-b[/tex]

Answer:

123201

Step-by-step explanation:

This is an arithmetic sequence of common difference 2 and starting value 1,

So we can use the formula for an arithmetic sequence  if we know what is the order of the last term.

Then first use the formula for the nth term to find "n":

[tex]a_n=a_1+(n-1)d[/tex]

where d = 2, first term = 1 and last term = 701

[tex]a_n=a_1+(n-1)d\\701=1+(n-1)*2\\700=(n-1)*2\\350=n-1\\n = 351[/tex]

Knowing this, we can estimate the partial sum:

[tex]S=n\,\frac{a_1+a_n}{2} \\S=351\,\frac{1+701}{2} \\S=351\,*\,351\\S = 123201[/tex]

Step-by-step explanation:

16 avocados costs = $8, 20 avocados costs = $10 and 9 avocados costs = $4.5

The amount of money that a company spends on the creation or production of goods or services.

Given that, Eight avocados cost $4.

Therefore, each of them costs = 4/8 = 1/2

So, 16 avocados = 16*1/2 =$8

20 avocados = 20*1/2 =$10

9 avocados = 9*1/2 =$4.5

Hence, 16 avocados costs = $8, 20 avocados costs = $10 and 9 avocados costs = $4.5
