Answer: The equation can also be used to find the perimeter of the rectangle  P = 4 × ( l + w).

Step-by-step explanation:

Given data,

A rectangle has a length of 6 feet and a width of 4 feet.

The perimeter of the rectangle can be found using the equation =2×6+2×4.

                        P = 2×6+2×4

Let l be the length and w be the width of a rectangle.

Since there four sides of a rectangle, the perimeter is given by adding all the sides.

Therefore perimeter of the rectangle is given by

                    = l + l + b + b

                    = 2×l +2×w

                    = 2 × ( l + w).

The equation given by 2 × ( l + w) can also be used to find the perimeter of any given rectangle.

We can use,

                          P = 4x4x6

Therefore perimeter of the rectangle is given by

                           = l + l + b + b

                           = 4×l +4×w

                           = 4 × ( l + w).

substitute l and w values,

Then,

                           = 4 × ( l + w)

                        P = 4 × ( 6 + 4).

The equation given by 4 × ( l + w) can also be used to find the perimeter of any given rectangle.

Therefore,

The equation can also be used to find the perimeter of the rectangle P = 4 × ( l + w).

Round to a "significant figure."

(I don't know what that's referring to. The nearest whole number is 2.)

The solution of the given equation by rounding off it to the nearest ten-thousandth is 1.2063.

What is a round-off of the digit?

In mathematics, a round-off is defined as an approximation of the given number to a fewer number of significant digits by taking into consideration some rules.

For eg: 13.58 ~ 13.6

Solving the given equation: 4³x=77.2

We are given that 4³x = 77.2            —- 1

We know that 4³ = 64

Using in equation 1, we have,

64x = 77.2

x = 77.2 / 64

= 1.20625

Hence, the solution of the given equation rounded off to the nearest ten-thousandth is 1.2063.

The value of g (7) is 16.

What is Piecewise function?

A piecewise function is a function which built from pieces of different functions over different intervals.

The given function is;

g (x) = x² - 5             , x ∈ (-∞, -7)

      = 9x - 17            , x ∈ [-7, 2]

      = (x + 1) (x - 5)    , x ∈ (2, ∞)

Now, Find the value of g (7) as;

Since, Number 7 is belong in interval (2, ∞).

Hence, To find the value of g (7) we use the function,

g (x) = (x + 1) (x - 5)    , x ∈ (2, ∞)

Substitute x = 7 we get;

g (x) = (7 + 1) (7 - 5)

g (7) = 8 * 2

g (7) = 16

Knowing that segment BD is of length 26, and C is the midpoint then BC is half of BD. The value of  x is solved to be 11/3

Given data

length of segment BD = 26

C midpoint of BD

BC = 6x - 9

If C midpoint of BD, then BC is half of BD.  This is shown mathematically as

BC = 1/2 * BD

BC = 1/2 * 26

BC = 13

substituting BC = 13 into BC = 6x - 9, we have

BC = 6x - 9

13 = 6x - 9

13 + 9 = 6x

6x = 22

x = 22/6

x = 11/3 in fraction

x = 3.6667 in decimal notation.

Revolution traveled by my friend = 20π ft.

Difference between revolutions = 10π ft.

Step-by-step explanation:

In one revolution, I travel 2π(15) = 30π ft., and my friend travels 2π(10) = 20π ft., so my revolution is 30π - 20π, or 10π, ft. longer than my friend's revolution.

1. If two lines are perpendicular, then the four angles caused by them are right angles

2: 1. Inductive

2. Deductive reasoning

1. If two lines are perpendicular, then the four angles caused by them are right angles.

Two lines are perpendicular when the angles formed by them are right angles.

The vertically opposite angles formed by intersecting lines have equal measure, and linear pair angles are supplementary, therefore;

If one of the angles formed by intersecting lines is known to be 90°, the vertical and adjacent angles are also 90°, and by the sum of angles at a point property, the remaining angle is also, 90°, which indicates that all the angles formed are right angles (90°).

The acceleration of the bicyclist is 6.83 m/s².

The given parameters;

Initial velocity of the bicycle (u) = 21 m/s

Distance travel by the bicycle (s) = 32.3 m

We have to find the acceleration of the bicyclist.

How to calculate the acceleration?

If the initial velocity is u, final velocity is v and distance travel by object is s then we can calculate acceleration as;

v² = u² + 2as

Initial velocity of the bicycle (u) = 21 m/s

Distance travel by the bicycle (s) = 32.3 m

Final velocity of the bicycle (v) = 0

Hence, The acceleration of the bicycle is calculated as follows;

v² = u² + 2as

Where, v is the final velocity of the bicycle.

0 = u² + 2as

2as = - u²

a =  - u²/2s

a = - (21)²/2*32.3

a = - (21)²/64.6

a = -441/64.6

a = -6.83

| a | = 6.83 m/s²

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

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 is 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.

If we restrict the domain to [−1,∞), then this new function has an inverse:

g(x) = (x+1)² with x ≥ −1

y = (x+1)²

if and only if

x+1 = √y (We do not need ±√y because of the restriction on x.)

x = √y−1

g−1(x) = −√x−1

If we restrict the domain to (−∞, −1], we get

h(x) = (x+1)² with x≤−1

y = (x+1)²

if and only if

x+1 = −√y (We need only −√y because of the restriction on x.)

x = −√y−1

h − 1(x) = √x−1
