According to this rule, if the exponent is negative, we can change the exponent into positive by writing the same value in the denominator and the numerator holds the value 1.
The negative exponent rule is given as:
5. 3 x 10^-4
= 5.3/10^4 (1)
-5. 3 x 10^4
-(5.3 * [tex]10^{4}[/tex]) (2)

Option (B) is correct.
What is the triangle similarity test?
The triangle similarity test is a method used to determine whether two triangles are similar or not. Similar triangles are triangles that have the same shape but different sizes. They are similar if their corresponding angles are congruent and their corresponding sides are in proportion. There are several ways to test for similarities, such as the side-side-side (SSS) test, the angle-angle-side (AAS) test, and the side-angle-side (SAS) test.
In the given figure, triangle KLM is similar to Triangle ORS.
and by the property of similar triangles, sides of similar triangles are in proportion:
so we can write:
LM/RS = KL/OR
15/4 = x/8
[tex]\frac{15}{4}=\frac{x}{8}\\\\\frac{8}{4}=\frac{x}{15}[/tex]
Hence, the ratio which can be used to calculate the height of the building would be [tex]\frac{8}{4}=\frac{x}{15}[/tex].

A rectangular pool has an area of 640 square feet. The length is 12 feet shorter than the width.
The rectangular pool has a width of 80 feet and a length of 68 feet. The area is 640 square feet and the length is 12 feet shorter than the width.
1. 640 divided by 12 = 53.33
2. 53.33 + 12 = 65.33
3. Width = 65.33 feet
4. Length = Width - 12 = 65.33 - 12 = 53.33 feet
The area of the rectangular pool is 640 square feet. To find the width, we divide 640 by 12 because the length is 12 feet shorter than the width. 640 divided by 12 gives us 53.33. We add 12 to this number to get the width of the pool, which is 65.33 feet. To find the length, we subtract 12 from the width, which gives us 53.33 feet. Therefore, the width of the pool is 65.33 feet and the length is 53.33 feet. The area of the pool is 640 square feet and the length is 12 feet shorter than the width.

What is co-prime numbers for Class 6?.
Co-prime numbers are those numbers that have only one common factor, namely 1.
Coprimes are pair of numbers that have no common factor other than 1. There should be at least two numbers to form a set of coprimes. Such numbers have only 1 as their highest common factor, for example (4 and 7), (5, 7, 9) are co-prime numbers. It should be noted that concurrent primes need not always be primes. If the only common factor of two numbers a and b is 1, then a and b are coprimes. In this case, (a, b) is considered a prime pair. Minor primes are also referred to as relatively primes. To determine whether any two numbers are co-prime, we first find their greatest common factor (GCF). If their GCF is 1, we can say they are co-prime. Consider the two numbers 5 and 9. The factors of 5 are 1 and 5. The factors of 9 are 1, 3, and 9. The factor that is common to both 5 and 9 is 1. The GCF of (5, 9) = 1. Thus, (5 , 9) is a co-prime pair.

The remote interior angles of ∠1 are 34° and the right angle. The amount of m∠2 is 56°.
∠1 is an exterior angle because it is located outside the triangle. It has 2 remote interior angles. Remote interior angles are the angles with no shared vertex with the exterior angle. In this case, the remote interior angle of ∠1 is angle 34° and the right angle.
m∠1 can be measured by adding the remote interior angles:
m∠1 = 34° + 90°
m∠1 = 124°
Since m∠1 share a vertex with m∠2, then the total of both angles should be equal to 180° (a straight line). Hence:
m∠1 + m∠2 = 180°
Using the value of m∠1 known above, we can find the value of m∠2:
m∠1 + m∠2 = 180°
124° + m∠2 = 180°
m∠2 = 56°

what are the coordinates of point M after a 90° clockwise rotation about p
The coordinates of point M after a 90° clockwise rotation about P is (0, -3).
Define the 90° clockwise rotation?Our point A(x,y) becomes A' when a point is rotated 90 degrees anticlockwise about the origin (-y,x). To put it another way, flip x and y, and give y negative.When position M (h, k) is rotated through 90 degrees in a clockwise direction around the origin O, the rotation of the point occurs. M' will represent the updated location of position M' (k, -h).Thus, by applying the rule of 90° clockwise rotation-
M = (3,0) taking P as reference point .
M' = (0, -3) after 90° clockwise rotation.

Which values are within the range of the piecewise-defined function?
The values within the range of the piecewise-defined function are
y = -6, y = -4, y = 1 and y = 3.
What is a piecewise function?A piecewise function, or f(x), is a function with various definitions at various intervals of x. A piecewise function's graph is divided into sections that each correspond to one of its definitions. A very good illustration of a piecewise function is the absolute value function.
Given f(x) = 2x + 3, if x < -3
f(x) = x, if x = -3
f(x) = -x - 2, if x > -3
the function will be at x ≤ -3 and x ≥ -3
We now wish to determine which values fall within this function's range. Keep in mind that the set of possible outputs from a function constitutes its range.
The range of the first part of the function f(x) = 2*x + 2 has an upper bound at x = -3
f(-3) = 2*-3 + 2 = -6 + 2 = -4
Then the range of the first part is (-∞, -4)
Notice that the actual value -4 belongs to the range because x is smaller than and equal to -3.
The range of the second part has a lower bound for x = -3, the lower bound is:
f(-3) = -(-3) - 2 = 1
Then the range of this part is (1, ∞)
Then the range of the piecewise function is:
(-∞, -4) U (1, ∞)
and including -4 and 1
y = -6, y = -4
y = 1, y = 1
Hence values in the range are y = -6, y = -4, y = 1, and y = 3.

A magnitude 8 on the Richter scale is 100 times more ground shaking than one that measures 6 on the Richter scale.
The magnitude of an earthquake is determined using the logarithm of the amplitude (height) of the largest seismic wave, calibrated to a scale by the seismometer. The Richter scale was originally developed to measure the magnitude of moderate earthquakes (magnitude 3 to magnitude 7) by assigning numbers so that the magnitude of one earthquake can be compared to another. We have, maganitude of two earthquakes, 8 and 6 Let the magnitude of first earthquake be A and second be B . So, A = 8 , B = 6 , to compare two earthquakes in terms of shaking, you subtract one magnitude from the other and raise 10 to that power, 10⁽ᴹ ⁻ ᴹ´⁾

How do you find the bisector of an equilateral triangle?.
An angle bisector of a triangle is a line segment that divides an angle into two congruent angles. In an equilateral triangle, all angles are congruent (60 degrees), so any line segment that divides an angle into two congruent angles is also an angle bisector.
To find the angle bisector of an equilateral triangle, you can use the following method:
Draw an equilateral triangle.
Choose an angle and draw the angle bisector from the vertex of the angle to the midpoint of the opposite side.
Since all the angles of an equilateral triangle are congruent, the angle bisector that you drew bisects any angle of the triangle.
Alternatively, you can use the following method:
Draw an equilateral triangle.
Connect the midpoint of one side of the triangle to the opposite vertex.
The segment that you drew bisects the angle of the triangle.
It is important to note that in an equilateral triangle, all medians, altitudes, angle bisectors, and perpendicular bisectors are congruent, they all divide the triangle in the same ratio, so they all meet at the same point, called the centroid, which is 2/3 of the distance from each vertex to the midpoint of the opposite side.
What is the extended ratio relating the side lengths of a 30 60 90 triangle?.
Answer:
Remembering the 30-60-90 triangle rules is a matter of remembering the ratio of 1: √3 : 2, and knowing that the shortest side length is always opposite the shortest angle (30°) and the longest side length is always opposite the largest angle (90°).
