Answer:

[tex]\displaystyle \lim_{x\to \infty}\frac{3x^2+4.5}{x^2-1.5}=3[/tex]

Step-by-step explanation:

We want to evaluate the limit:

[tex]\displaystyle \lim_{x\to \infty}\frac{3x^2+4.5}{x^2-1.5}[/tex]

To do so, we can divide everything by x². So:

[tex]=\displaystyle \lim_{x\to \infty}\frac{3+4.5/x^2}{1-1.5/x^2}[/tex]

Now, we can apply direct substitution:

[tex]\Rightarrow \displaystyle \frac{3+4.5/(\infty)^2}{1-1.5/(\infty)^2}[/tex]

Any constant value over infinity tends towards 0. Therefore:

[tex]\displaystyle =\frac{3+0}{1+0}=\frac{3}{1}=3[/tex]

Hence:

[tex]\displaystyle \lim_{x\to \infty}\frac{3x^2+4.5}{x^2-1.5}=3[/tex]

Alternatively, we can simply consider the biggest term of the numerator and the denominator. The term with the strongest influence in the numerator is 3x², and in the denominator it is x². So:

[tex]\displaystyle \Rightarrow \lim_{x\to\infty}\frac{3x^2}{x^2}[/tex]

Simplify:

[tex]\displaystyle =\lim_{x\to\infty}3=3[/tex]

The limit of a constant is simply the constant.

We acquire the same answer.

Answer:

a. Jacques will be 46.4m below the surface and his assistant will be 78.1m below the surface.

b. 10 minutes

c. 6 minutes

Step-by-step explanation:

Let the equation for Justin's motion be J(x)=-13.9-7.5x (where J(x) is his distance from the surface in metres and x is time in minutes), because he starts off 13.9m below the surface and descends 7.5m every minutes.

Let the equation for the assistant be a(x)=-97.3=+6.4x (where a(x) is his distance from the surface in metres and x is time in minutes), because he starts off 97.3m below the surface and ascends 6.4m every minutes.

a.

J(x)=-13.9-7.5x

J(3)=-13.9-7.5(3)=-13.9-22.5=-36.4

a(x)=-97.3=+6.4x

a(3)=-97.3+6.4(3)=-97.3+19.2=-78.1

b.

a(x)=-97.3=+6.4x

-33.3=-97.3=+6.4x

64=6.4x

x=10

c.

when divers are at the same depth, J(x)=a(x)

J(x)=a(x)

-13.9-7.5x=-97.3=+6.4x

83.4=13.9x

x=6

Answer: Its 140

Step-by-step explanation:

I do russian math too... :(

but ya I don't know how to do it.

Applying the angles of intersecting chords theorem, the measure of arc EI is: 140°.

Based on the angles of intersecting chords theorem, the measure of the vertical angle formed when two chords intersect equals half the sum of the measures of the intercepted arcs.

Given the following:

m∠K = 1/2(2(EY) -m(JL))

25 = 1/2(2(m(EY)) -m(JL))

50 = 2(m(EY)) -m(JL)

m(JL) = 2(m(EY)) - 50

m∠EXY = 1/2(m(JL) + m(EY) [angles of intersecting chords theorem]

Substitute

80 = 1/2[2(m(EY)) - 50 + m(EY)]

2(80) = 2(m(EY)) - 50 + m(EY)

160 = 3(m(EY)) - 50

160 + 50 = 3(m(EY))

210 = 3(m(EY))

210/3 = m(EY)

m(EY) = 70°

m(EI) = 2(m(EY)) = 2(70)

m(EI) = 140°

Therefore, applying the angles of intersecting chords theorem, the measure of arc EI is: 140°.

Answer:

x=22/9

Step-by-step explanation:

4(3√(x-2))+1=9

4(3√(x-2))=8

3√(x-2)=2

√(x-2)=2/3

x-2=4/9

x=4/9+2

x=4/9+18/9

x=22/9

Therefore, the solution is x=22/9

Answer:

x=16, y=-4

Step-by-step explanation:

-1(x-y=12)

x+7y=-20

-x+y=-12

x+7y=-20

8y=-32

y=-4

x-4=12

x=16

Answer:

x= 8, y= -4

Step-by-step explanation:

You can subtract one equation by another to eliminate x

(x-y)-(x+7y)=12-(-20)

-8y = 32

y= -4

Substitute y =  -4 in the first equation:

x-(-4) = 12

x =8

Answer: $3,833.20

Step-by-step explanation:

Mortgages interest and property tax are both federal deductions so they will reduce taxes:

= 10,260 + 3,430

= $13,690

The tax saving is therefore:

= 13,690 * tax rate

= 13,690 * 28%

= $3,833.20

Answer:

24 glasses

Step-by-step explanation:

If a glass holds 1/6 liters of liquid, that means that 6 of them can hold one liter

1/6 * 6 = 1

and if 6 of them can hold 1 liter, that means 24 of them can hold 4 liters

6 * 4 = 24

Answer:

600 sq.ft.

Step-by-step explanation:

10 * 24 = 240 / 2 = 120

20*24 = 480

480+120 = 600

600 sq.ft.

Answer:

720

Step-by-step explanation:

So there are two things you need to remember to sovle this problem.

First, the formula for area of a square. This is just base x height.

Second, the formula for area of a triangle. THis is just 1/2 x base x height.

Lets plug our values into both formulas and see what we get.

So the area of the square would be:

24 x 20.

This is 480.

Now that we know the area of the square is 480, lets find the area of the traingle:

1/2 x 24 x 20

This will get you 240.

Low lets just add the two together, and we get:

240+480=720

So the area is:

720

Answer: Base and Height

Step-by-step explanation: You would multiply the base and height. Since it is not a triangle you wouldn't divide it by 2

So far, we have found area for rectangles, triangles, trapezoids, and circles. An irregular figure is a figure that is not a standard geometric shape. Its area cannot be calculated using any of the standard area formulas. But some irregular figures are made up of two or more standard geometric shapes. To find the area of one of these irregular figures, we can split it into figures whose formulas we know and then add the areas of the figures.
