The perimeter of a rectangular window is 43 feet. The width of the window is 5 ft more than the length. Find the width of the window

Answers

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.

Find the derivative of the function. y = sin−1(6x + 1)

Answers

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]

Use S = n^2 to find the sum of 1 + 3 + 5 + . . . + 701.

Answers

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]

Eight avocados cost $4.

How much do 16 avocados cost?
How much do 20 avocados cost?
How much do 9 avocados cost?

Answers

16 avocados cost $8
20 avocados cost $10
9 avocados cost $4.5

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

What is the Cost?

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

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]
