The difference on the change of elevation is 440 feet.

From the information, it was stated that the hiking trail starting point is 180 ft below sea level and that the ending point is 260 above sea level.

Therefore, the difference in the change will be:

= Ending level - Starting level

= 260 - (-180)

= 260 + 180

= 440 feet

The value of x for the given logarithmic equation 2㏒x = -4 is x = 0.01.

A logarithmic equation contains the log of a variable-containing representation. To begin dealing with exponential equations, check to see if both sides of a equation can be described as powers of a exact number.

The ㏒x function has the following properties:

Now, as per the given question;

The given equation is  2㏒x = -4.

Divide both side by 2.

㏒x = -2

Again, rewrite this function ㏒x = -2 in the exponential form by implementing  properties of ㏒.

Let x and a be the positive real numbers such that a ≠ 1, then,

㏒ₐx = y is equivalent to [tex]a^{y}[/tex] = x.

Then,

10⁻² = x

Now, solve the value of x.

x = 1/100

x = 0.01 in the decimal form.

Therefore, the obtained value of the logarithmic function 2㏒x = -4 is x = 0.01.

In mathematics, an inverse function is one that "reverses" another function. The inverse of y = 2x + 8 is f⁻¹(x) = x/2 − 4.

The inverse function of a function f in mathematics exists a function that reverses the operation of f. If the inverse of f exists, it is shown by the f⁻¹. The inverse of f exists if and only if f exists bijective.

An inverse in mathematics is a function that "undoes" another function. In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f ⁻¹.

Let the function be y = 2x + 8

Interchange the variables.

x = 2y + 8

Solving for y

y = x/2 − 4

Replace y with f⁻¹(x), we get

f⁻¹(x) = x/2−4

Verify if f⁻¹(x) = x/2−4 is the inverse of f(x) = 2x+8.

The inverse of y = 2x+8 is f⁻¹(x) = x/2−4.

Determine if 36 is a cube root

(a-b)•(a^2+ab+b^2) =

           a^3+a^2b+ab^2-ba^2-b^2a-b^3 =

Answer:

yes, it is a function

Step-by-step explanation:

y = -x + 4 is a line. In order to be a function every input can have only one output. Any x you put into that equation will spit out only one y. It passes the vertical line test (ALL lines except a vertical line pass the vertical line test.) So it is a function.

Step-by-step explanation:

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 9, 31) and (x₂, y₂ ) = (15, - 41) ← 2 ordered pairs from the table

m = [tex]\frac{-41-31}{15-(-9)}[/tex] = [tex]\frac{-72}{15+9}[/tex] = [tex]\frac{-72}{24}[/tex] = - 3

the y- intercept is the value of g(x) when x = 0 , then from the table

y- intercept = 4

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept ) , then equation is

y = - 3x + 4

We need to know about translation, reflection and rotation to solve the problem. (1) We translate a triangle with respect to a horizontal and vertical direction. (2) We rotate a traingle about a given angle. (3) We refelct a triangle about a line of reflection which can be axis or vector.

(1) Translation of a triangle means changing it's position without changing the shape or size of the triangle. We translate a triangle with respect to a horizontal and vertical direction. We get the new triangle by adding the horizontal translation value to the x-coordinate and the vertical translation value to the y-coordinate.

(2) Rotation of a triangle is turning the triangle by an angle around a center point. When a triangle is rotated by 90° clockwise then (x,y) becomes (y,-x), when rotated by 90° anticlockwise (x,y) becomes (-y,x), when rotated by 180° clockwise or anticlockwise (x,y) becomes (-x,-y).

(3)Reflection of a triangle is finding a mirror like image of the triangle about  a line of reflection. The line of reflection may be either of the axes, a vector. To find the image we have to find the coordinates of the triangle that are of same distance from the line of reflection on the opposite side like they are from the original triangle.

Therefore we learnt about translation, reflection and rotation and saw that (1) Translation needs a horizontal and vertical direction for translating, (2) Rotation needs an angle of rotation and a center point and (3) Reflection needs a line of reflection.

1. The given equation is in the slope intercept form.

2. The standard form is x ₊ 2y = ₋6

3. The given equation is in the point slope form.

4. The standard form is 2x ₋ 3y = ₋3

Given,

the equation is y = ₋1/2x ₋ 3

the above equation is in the form of slope intercept form i.e,

y = mx ₊ c

Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, the distance may refer to a physical length or an estimation based on other criteria.

Now, the given formula is d=2r.

So, the formula for r is r=d/2

Distance = 130 miles

The area of the running track to the nearest tenth of a yard is 1456 yards

The length of the field is 100 yards with a width of 40 yards.

Notice that the two semicircles on both ends form a circle with diameter 40 yards. Since it's diameter is 40, then it's radius is 20. We can get the length of the rectangle by subtracting two 20 from 100 or subtracting it's diameter to the entire length 100:

= 100-20-20

=100-40

=60

Since we formed a rectangle with two semicircles on both ends, we have the length of the rectangle 60 yards and the width 40 yards.

We first get the circumference of the circle.

C=πd

=(3.14)(40)=125.6

Then we get the measure of the two lengths of the rectangle which is 60
