The road was 9.62 miles long after rebuilding.
How to calculate the length of the road ?
The road was initially 3.7 miles long
After a rebuild it was 2.6 miles as long
The new length can be calculated by multiplying the initial length which is 3.7 by 2.6
= 3.7 × 2.6
= 9.62
Hence, after the rebuild the road was 9.62 miles long

Let R be the rotation of center the origin O(0 , 0) and angle 270
Let M(z = x + iy) a point of the plane and its image M'(z' = x' + iy') by the rotation R.
Then
[tex]z^{\prime }=e^{i\frac{3\pi }{2} }\times z[/tex]
Then
x' + iy' = (0 -i)×(x + iy)
Then
x' + iy' = (-i) × (x + iy)
= -ix + y
Then
x' = y and y' = -x
Then
R transform M(x , y) to the point M'(y , -x)

Derek Jeter average was 4.9%greater than Jorge Posada 4.9% expressed as a percent.
To express decimal as percent we need to multiply the decimal with 100 .
The average or mean is defined as the sum divided by the frequency.
Here we have four averages given in decimal
Derek Jeter average in percentage =0.334*100=33.4%
Alex Rodriguez average in percentage=0.286*100=28.6%
Jorge posada average in percentage =0.285*100=28.5%
Hideki Matsui average in percentage=0.274*100=27.4%
From the above percentages Derek Jeter average was 4.9%greater than Jorge Posada =33.4-28.5=4.9%
Or we can say it as Derek peter percentage was 14.68% greater than Jorge Posada on a scale of 100 percentage.
Hence Derek peter percentage was 14.68% greater than Jorge Posada on a scale of 100 percentage and Derek Jeter average was 4.9% greater than Jorge Posada 4.9%.

Vani needs to order some new supplies for the restaurant where she works. The restaurant needs at least 795 forks. There are currently 315 forks. If each set on sale contains 10 forks, write and solve an inequality which can be used to determine xx, the number of sets of forks Vani could buy for the restaurant to have enough forks.
The number of sets of forks that Vani can buy for the restaurant is 48.
What is the minimum number of forks that Vani can buy?The first step is to determine the appropriate inequality sign to use:
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
The inequality sign that would be used is ≥.
(Number of forks per set x number of sets that would be bought) ≥ (number of forks needed - number of forks the restaurant has)
(10 × xx) ≥ (795 - 315)

Write each equation in logarithmic form.
1/10=10⁻¹
The logarithmic form of the equation is [tex]log_{10}\frac{1}{10}=-1[/tex] .
In mathematics, the logarithmic function is the inverse of power. Then the function is given as f(x) = log x The logarithm base is a. This can be read as the logarithmic base a of x. The two most common bases used in logarithmic functions are base 10 and base e. The logarithm function has several properties that allow the logarithm to be simplified when the input is in the form of products, quotients, or values raised to powers.We have given an equation [tex]\frac{1}{10} =10^{-1}}[/tex] .
Taking log on both sides , we get
[tex]log(\frac{1}{10}) =log(10^{-1})[/tex] ..(1)
Applying the property of logarithm which is given by [tex]loga^b=bloga[/tex] in equation (1) ,we get
[tex]log(\frac{1}{10}) =-log(10)[/tex]
On rearranging the above equation , we get
[tex]\frac{log(\frac{1}{10})}{log10} =-1[/tex] ..(2)
Applying the property of logarithm which is given by [tex]log_xy=\frac{log_ay}{log_ax}[/tex]\
[tex]\frac{log(\frac{1}{10})}{log10}[/tex] can be written as [tex]log_{10}\frac{1}{10}[/tex] using property

The function is positive when x < -1.75 and x > -0.25, and negative for -1.75 < x < -0.25, increasing when x > -1 and decreasing when x < -1.
What is the end behavior of the function?It is given by the values of y when x -> ∞.

For the end behavior, y -> + ∞ when x -> -∞ and y -> +∞ when x -> +∞.

The length of the rectangle is 6 meters and the width is 2 meters.
What is perimeter?Perimeter is the sum of the lengths of all the sides of a given 2D plane figure.
A rectangle area has a length that is 4 more than its width.
Assuming the width of the rectangle to be x meter,
∴ The length of the rectangle is (x+4) meters.
Also given that the rectangle area is 12 sq meters.
We know, that the area of a rectangle is a product of its length and width.
∴ [ x × (x+4) ] = 12.
x² + 4x = 12.
x² + 4x - 12 = 0.
x² + 6x - 2x - 12 = 0.
x(x+6) -2( x+6) = 0.
(x+6)(x-2) = 0.
x + 6 = 0 Or x - 2 = 0.
x = -6 or x = 2.
We know distance can not be negative so, x = -6 is inadmissible.
So, the width of the rectangle is 2 meters and length is (x+4) = (2+4) = 6 meters.
