On solving the provided question, we can say that vectors are -  4 miles E: <4, 0>; 4 miles SE: <2√2, -2√2>; 7 miles S: <0, -7>; 6 miles SW: <-3√2, -3√2>; 2 miles E: <2, 0>

In mathematics, a vector is a quantity with magnitude and direction but no location. Acceleration and velocity are two examples of such numbers. A thing with both magnitude and direction is called a vector. A vector can be conceptualised geometrically as a directed line segment, the length of which corresponds to the magnitude of the vector, and the direction of which is denoted by an arrow. Size and direction are two independent characteristics of a quantity or phenomena known as a vector. The phrase also describes how these numbers are represented mathematically or geometrically. In nature, vectors may be found in electromagnetic fields, weight, momentum, force, and velocity.

4 + 4 + 7 + 6 + 2 = 23 miles.

vectors are -

4 miles E: <4, 0>

4 miles SE: <2√2, -2√2>

Answer: x= 9.2

Scale Factor is 2.5

Step-by-step explanation:

1. Divide 17.5 by 7 to find scale factor

2. So 17.5/7=2.5

3. Divide 23 by 2.5 to find x

4. So 23/2.5=9.2

Answer:

Scale Factor: 2.5

x = 9.2

Step-by-step explanation:

So, the simple way to find this is by first figuring how much the new triangle has shrunk. Since they gave you both the bottom numbers, all you have to do is divide 17.5 by 7 to give you the scale factor of 2.5. You will use this scale factor to divide the 23 and get your answer of 9.2.

5 * root(x ^ 2, 3) is the equivalent expression.

Simply multiplying the radicands and placing the result behind the radical sign is all that is required to multiply two square roots. The square root of the product of the radicands, in other words, is equal to the product of two square roots.

Only if the numbers under the radical sign are equal can you add or subtract square roots themselves. The original number will still be in the radical sign after adding or subtracting the coefficients (numbers in front of the radical sign). Implement the suggested action.

Perpendicular lines have negative reciprocal slopes.

Answer:

The answers are B ) A Symbol used to represent an unknown value and C ) Can be changed from one value to another

The exponential function f so that the slope of a line from the point (0, f(0)) to the point (2, f(2)) is equal to 12 is defined as follows:

f(x) = 5^x.

The general format of an exponential function is given as follows:

y = ab^x.

In which:

The slope of a line, given two points, is given by the division of the change in the output by the change in the input of these two points.

Considering that the slope of points (0, f(0)) and (2, f(2)) is equals to 12, we have that:

[f(2) - f(0)]/(2 - 0) = 12

f(2) - f(0) = 24.

One case that satisfies this involves these two following points.

Hence the parameter a is given as follows:

a = 1.

When x = 2, y = 25, meaning that the parameter b is calculated as follows:

b² = 25

b = 5.

Hence the exponential function is:

f(x) = 5^x.

The solution of the pair of equations y = 0 and y = -3 is y = -3/2.

The given pair of equations is:

y = 0

y = -3

We can solve this pair of equations using elimination. To do this, we first add the two equations together, which gives us:

y + y = 0 + (-3)

2y = -3

We then divide both sides by 2 to get the solution for y:

2y/2 = -3/2

y = -3/2

The shape of a decagon will remain the same when it is rotated through

its angle of rotational symmetry.

The rotation about the center will carry a regular decagon back to itself is 36°.

Note the following

The angle of rotational symmetry of a decagon is the smallest angle that a decagon can be rotated by such that the image formed by the rotation coincide with the preimage;

A decagon has 10 sides, the interior angle of a regular decagon is given as follows;

Each interior angle =  (n-2)*180/10 = 144⁰

A decagon has a reflective symmetry, therefore, the lines of symmetry joining opposite vertices are straight lines.

The number of diagonals in a decagon = 5

Rotating through the vertex and opposite vertex of the diagonals gives the number of image of the rotation that is similar to the preimage of a decagon as ten.

Therefore, a rotation of  (360/10) = 36⁰, about the center will carry a regular decagon back to itself.
