The inverse of the given equation is r = (10D - 5)/11 which represents the reaction speed of the car in terms of the reaction distance.
The car travels a distance of D feet, where D is a function of the speed r miles/hour given by D(r) = (11r + 5)/10
D = (11r + 5)/10
⇒ 10D = 11r +5 (multiply by 10 on both sides)
⇒ 10D - 5 = 11r (subtracting 5 on both sides)
⇒ (10D - 5)/11 = r (dividing by 11 on both sides)
Therefore, the inverse of the given equation is r = (10D - 5)/11.
Inverse represents the speed of the car (miles/hour) in terms of the reaction distance D.
The inverse is also a function, which represents the reaction speed of the car in terms of the reaction distance.
Therefore. the inverse of the given equation is r = (10D - 5)/11 which represents the reaction speed of the car in terms of the reaction distance.

What is the equation of the line that passes through the point (-5,-6) and has a slope of 1/5
the equation of the line that has a slope of 1/5 and passes through (-5, -6) is: y = 1/5x - 5.
How to Find the Equation of a Line?Given that the line passes through (-5, -6), and has a slope (m) = 1/5, to find the equation of the line, do the following:
Substitute (x, y) = (-5, -6) and m = 1/5 into y = mx + b to find the value of b:
-6 = 1/5(-5) + b
-6 = -1 + b
Add 1 to both sides
-6 + 1 = -1 + b + 1
-5 = b
b = -5
Substitute m = 1/5 and b = -5 into y = mx + b
y = 1/5x + (-5)
y = 1/5x - 5
Thus, the equation of the line that has a slope of 1/5 and passes through (-5, -6) is: y = 1/5x - 5.

A pentagon has vertices at (-1,-1), (-5,-2), (-6,-4), (-4,-7), and (-2,-3). If the pentagon is rotated 180* coordinates of the vertices of the image?
Answer:
(1, 1) , (5, 2), (6, 4), (4, 7) and (2, 3)
Step-by-step explanation:
When a point is rotated 180° about the origin(either clockwise or anticlockwise), the transformed coordinates are the negatives of the original coordinates.
Thus when a point (x, y) is rotated about the origin, its new coordinates become (-x, -y)
Given the original 5 vertices of the pentagon, the vertices of the rotated pentagon are transformed as follows
Original Vertex ==> Transformed Vertex
(-1, -1) ==> (1, 1)
(-5, -2) ==> (5, 2)
(-6, -4) ==> (6, 4)
(-4, -7) ==> (4, 7)
(-2, -3) ==> (2, 3)

Darla can spend the greatest total cost of groceries in order to spend as close to $15 as possible is approximately $14.20.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Let the cost of the groceries be represented as "c", then we have;
Cost price + VAT = c + (5% of c)
In order to get the cost, c, that make him spend as close to $15. Since the tax is 5% of the cost price, then the cost price will be close to $15.
Let c = $14.20, then;
So that,
c + (5% of c) = 14.20 + (5% of 14.20)
= 14.20 + 0.71
= $14.91
Therefore, the greatest total cost of groceries she can spend in order to spend as close to $15 as possible is approximately $14.20.

Find the area of a cement walkway of width x meters around a 50m by 25m pool.
The area of a rectangular cement walkway of width x meters around a 50m by 25m pool is 4x²+150x sq. meters.
What is an area of a rectangle?Rectangle area in geometry refers to the area that a rectangle occupies on a two-dimensional plane. A rectangle is a form of a quadrilateral, a two-dimensional object with four sides and four vertices. The four angles of the rectangle are all perfectly right angles or 90 degrees. The opposing sides of the rectangle are equal and parallel.
Area of Rectangle = Length × Breadth
In the given question,
The width of the walkway is x meters.
Width of the pool= 25+2x meters
and the Length= 50+2x.
So the area of the walkway with the pool is
= (25+2x)+(50+2x)
= 1250+100x+50x+4x²
= 4x²+150x+1250 sq. m
Area of the pool= 50x25
= 1250 sq. m
Area of the walkway= 4x²+150x+1250-1250
= 4x²+150x sq. meters.
Hence, the answer is 4x²+150x sq. meters.

ln (2 x-1)²=7
The simplification of the given logarithmic functions ln (2x-1)² = 7 is 17.055.
What are called the logarithmic functions?The logarithm of a number is the exponent by which a fixed value referred as the base should always be raised to generate a certain number. For instance, because 1000 is 10 to the third power, a log of 1000 to base 10 is 3.
The y-intercept doesn't really exist.A vertical asymptote is x = 0. *Mention: An asymptote is a line that a graph moves as the absolute value of x and otherwise y increases.A logarithmic function does not have a horizontal asymptote.The x-intercept is one.The function is spreading across the domain.If the base is between 0 and 1, the function diminishes out across domain.Some properties of the logarithmic functions are defined as-
Quotient Rule: ㏒(A/B) = ㏒A - ㏒BProduct Rule : ㏒A + ㏒B = ㏒(AB)Power Rule: n㏒A = ㏒AⁿBase Rule = ㏒ₐb = ㏒ₓb/㏒ₓaExponent Rule = e∧lnx = xAs, for the stated log or ln function ln (2 x-1)²=7
Use the power rule on the left side of the equation.
2 ln (2 x-1) = 7
Simplifying the equation.
ln (2 x-1) = 7/2
ln (2 x-1) = 3.5
Using the exponential property of the log.
e∧[ln (2 x-1)] = e∧3.5
2x-1 = 33.11
2x = 33.11 + 1
2x = 34.11
x = 34.11/2
x = 17.055

Expand each logarithm.
log a²b³ / c⁴
The answer to the present question is: log(a²b³/c⁴) = 2log(a) + 3log(b) - 4log(c)
For solving this kind of question, we are going to use these three identities:
log(x*y) = log(x) + log(y) ....(1)
log(x/y) = log(x) - log(y) ....(2)
log(xⁿ) = nlog(x) ....(3)
So, using (2), log(a²b³/c⁴) may be written as: log(a²b³) - log(c⁴) ....(4)
Again, using (1), log(a²b³) are often written as: log(a²) + log(b³) ....(5)
Now, Putting equation (4) in equation (3), we get:
log(a²) + log(b³) - log(c⁴) ....(5)
Now, using (3), expanding all the terms, we get:
log(a²) = 2log(a)log(b³) = 3log(b)log(c⁴) = 4log(c)
Putting of these in equation 5, we get:
2log(a) + 3log(b) - 4log(c)
Therefore, log(a²b³/c⁴) = 2log(a) +3log(b) - 4log(c)
