The value of log  43is 1.633

Step-by-step explanation:

Explanation:

Suppose you know that:

[tex]\begin{array}{l}{\log 2 \approx 0.30103} \\{\log 3 \approx 0.47712}\end{array}[/tex]

Then note that:

[tex]43=\frac{129}{3} \approx \frac{128}{3}=\frac{2^{7}}{3}[/tex]

So

[tex]\log 43 \approx \log \left(\frac{2^{7}}{3}\right)=7 \log 2-\log 3 \approx 7 \cdot 0.30103-0.47712=1.63009[/tex]

We know that the error is approximately:

[tex]\log \left(\frac{129}{128}\right)=\log 1.0078125=\frac{\ln 1.0078125}{\ln 10} \approx 0.00782 .3=0.0034[/tex]

Answer:

length is 28 meters

width is 15 meters

Step-by-step explanation:

Write out formulas and assign variables:

Width: w

Length: l = 2w - 2

Here is a diagram:

            2w - 2              

|                                     |  w

|_________________|

The perimeter formula for rectangle is P = 2(l +w). Substitute the perimeter and the formula for length into the formula.

P = 2(l +w)

86 = 2(2w - 2 + w)       Simplify inside the brackets

86 = 2(3w - 2)            Divide both sides by 2

43 = 3w - 2              Add 2 to both sides

45 = 3w                  Divide both sides by 3

w = 45/3               Variable on left side is standard formatting

w = 15                 Width of basketball court

Substitute width into the length formula to fin length.

l = 2w - 2

l = 2(15) - 2

l = 30 - 2

l = 28           Length of basketball court

Therefore the length is 28 meters and the width is 15 meters.

The dimensions of the basketball court are 28 meters in length and 15 meters in width.

We need to find the dimensions of the rectangular court where the length (L) is 2 meters less than twice the width (W), given that the perimeter is 86 meters. We can set up the equations as follows:

First, substitute the value of L from the first equation into the second equation:

Simplify and solve for W:

Now, find the length (L):

Thus, the dimensions of the court are 28 meters in length and 15 meters in width.

[tex]\large \boxed{\text{101 pieces}}[/tex]

Step-by-step explanation:

1. Calculate the area of the floor

The formula for the area of a trapezoid is  

A = ½(a + b)h,

where a and b are the lengths of the parallel sides and h is the distance between them.

However, we are not given the value of h, so we must use Brahmagupta's formula.

If the four sides are a, b, c, and d, the area A is

[tex]A = \sqrt{(s - a) (s - b) (s - c) (s - d)}[/tex]

where s is the semiperimeter

[tex]s = \frac{1}{2}(a + b + c + d)[/tex]

Data:

a = 13 ft

b = 16 ft

c = 13 ft

d = 26 ft  

(a) Calculate the semiperimeter

[tex]\begin{array}{rcl}s & = & \sqrt{(s - a) (s - b) (s - c) (s - d)}\\\\ & = & \frac{1}{2}(13 + 16 + 13 + 26)\\\\ & = & \frac{1}{2}(68)\\\\ & = & 34\\\end{array}[/tex]

(b) Calculate the area

[tex]\begin{array}{rcl}A & = &\sqrt{(s - a) (s - b) (s - c) (s - d)}\\\\& = &\sqrt{(34 - 13) (34 - 16) (34 - 13) (34 - 26)}\\\\& = &\sqrt{21 \times 18 \times 21 \times 8}\\\\& = & \sqrt{63504}\\\\ & = & \mathbf{252}\\\end{array}[/tex]

The area of David's floor is 252 ft².

Answer:

The value of x is 22.

Step-by-step explanation:

We are given that,

12 less triple the difference of x and 10 is 24.

So, according to question :

  3(x - 10) - 12 = 24

Adding '12' on both sides of the above equation, we get

  3(x -10) - 12 + 12 = 24 + 12

⇒3(x - 10) = 36

Dividing the above equation by '3', we get

  3(x - 10) ÷ 3 = 36 ÷ 3

⇒x - 10 = 12

Now, adding '10' on both sides of the above equation, we get

  x - 10 + 10 = 12 + 10

⇒x = 22

So, the value of x is 22.

3 + 8x = 19 is the equation for given sentence three more than eight times a number is equal to 19

We have to translate the sentence into an equation

Let us first break the sentence and find out the equation

Let "x" be the required number

Given that, Three more than eight times a number is equal to 19.

Here "more than" represents addition

"times" represents multiplication

eight times a number = [tex]8 \times x[/tex]

So the required equation is:

Three more than eight times a number is equal to 19

[tex]3 + 8 \times x = 19\\\\3 + 8x = 19[/tex]

Answer:

Multiples of 2 are {2,4,6,8,10,12,14,16,...} Multiples of 4 are {4,8,12,16,.......) Hence common multiples are {4,8,12,16,...} and Lowest Common Multiple is 4 .

Step-by-step explanation:

To find common multiples of 2 and 4, list the multiples of each and identify the common elements. For 2 and 4, these are 4, 8, 12, and 16.

Finding Common Multiples of 2 and 4

To find common multiples of 2 and 4, we start by listing the multiples of each number.

→ Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, ...

→ Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, ...

Next, we look for common multiples from these lists.

→ 4: divisible by 2 and 4

→ 8: divisible by 2 and 4

→ 12: divisible by 2 and 4

→ 16: divisible by 2 and 4

Therefore, four common multiples of 2 and 4 are 4, 8, 12, and 16.

The x-coordinate of the point of intersection for given equations is 2

Step-by-step explanation:

Given equations are:

[tex]2x+y = 7\ \ \ Eqn\ 1\\10x-7y = -1\ \ \ Eqn\ 2[/tex]

The point of intersection is the solution of the system of equations

as we have to find the x-coordinate we will use elimination method to eliminate y

So,

Multiplying equation 1 with 7

[tex]7(2x+y) = 7(7)\\14x+7y = 49\ \ \ \ Eqn\ 3[/tex]

Adding equation 2 and 3

[tex](14x+7y) + (10x-7y) = 49-1\\14x+10x+7y-7y = 48\\24x = 48[/tex]

Dividing both sides by 24

[tex]\frac{24x}{24} = \frac{48}{24}\\x = 2[/tex]

The x-coordinate of the point of intersection for given equations is 2

Step-by-step explanation:

Given height of parabola is [tex]5\ m[/tex].

And [tex]2\ m[/tex] wide at ground level.

Also, the parabola opens down.

Let us assume the parabola is aligned on Y-axis

As the height of parabola is [tex]5\ m[/tex]. The maximum height of parabola is achieved when [tex]x=0[/tex].

So, the vertex of parabola is [tex](0,5)[/tex].

The equation of parabola having vertex [tex](h,k)[/tex] is.

[tex]y=a(x-h)^2+k[/tex].

Plugging the vertex of parabola

[tex](h,k)[/tex] [tex]=[/tex] [tex](0,5)[/tex].

[tex]h=0\ and\ k=5[/tex]

[tex]y=a(x-0)^2+5[/tex]

It is given that parabola is [tex]2\ m[/tex] wide at the ground.

As the parabola is aligned on Y-axis. So, distance between X-intercept is [tex]2\ m[/tex].

The X-intercept would be [tex](-1,0)\ and\ (1,0)[/tex]

Plugging [tex](1,0)[/tex] in the equation [tex]y=a(x-0)^2+5[/tex]

[tex]0=a(1-0)^2+5\\\\-5=a(1)^2\\\\-5=a[/tex]

Now, we get [tex]a=-5[/tex] and having vertex [tex]h=0\ and\ k=5[/tex].

So, the equation of parabola is

[tex]y=a(x-h)^2+k[/tex].

[tex]y=-5(x-0)^2+5[/tex]

In this question, we're trying to make an equation for the given scenario and answer a couple of leading questions.

We know that Aiko types at a rate of 70 words per minute

We would represent this as 70x

x = minutes

We are also given more information that he types 210 words in 3 minutes, that still follows our "70x" scenario.

So our equation would be:

y = 70x

The slope of the linear equation would be 70 or 70/1

The slope would be 70 because this is the change that's happening each minute.

A point on a graph would be at (1 , 70)

You would put this equation into a graph, and you would grab a point that's on the linear line. I'll insert a picture of the graph

The linear equation would be written as: y = 70x

The beginning point would be at 0, since Aiko doesn't type anything for 0 minutes.

Answer:

Answer:

  y = 3(x -4)^3 -3

Step-by-step explanation:

As you know, the transformations are

  g(x) = (vertical stretch factor) · f(x - (right shift)) +(vertical shift)

For the given transformations, the equation becomes ...

  y = 3(x -4)^3 -3

The equation of y=x^3 with the given transformations is y = 3(x - 4)^3 - 3.

The equation of y = x^3 after the given transformations is y = 3(x - 4)^3 - 3.

The vertical stretch by a factor of 3 means that all y-values will be multiplied by 3, so the equation becomes y = 3x^3.

The horizontal shift 4 units to the right means that x-values will be replaced by (x - 4), so the equation becomes y = 3(x - 4)^3.

The vertical shift 3 units down means that all y-values will be decreased by 3, so the equation becomes y = 3(x - 4)^3 - 3.
