( 31.2u + 0.2 v ) is expression represents the perimeter of rectangle .
What is rectangle short answer?
A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. Because of this, it is also known as an equiangular quadrilateral. Because the opposite sides of a rectangle are equal and parallel, it can also be referred to as a parallelogram.length of rectangle = ( 7.2u + 9.9v)
width of rectangle = ( 8.4u - 9.8v)
perimeter of rectangle = 2( l + b )
= 2 ( 7.2u + 9.9v + 8.4u - 9.8v )
= 2 ( 7.2u + 8.4u + 9.9v - 9.8v )
= 2 ( 15.6u + 0.1v )
= ( 31.2u + 0.2 v )

what is f(3)
The function f(3) has a value of 6
How to evaluate the function?The definition of the function is given as
f(n + 1) = f(n) - 2
Where
f(1) = 10
We start by substituting 1 for n in the equation f(n + 1) = f(n) - 2
So, we have
f(1 + 1) = f(1) - 2
Evaluate the like terms
So, we have
f(2) = f(1) - 2
Substitute f(1) = 10 in f(2) = f(1) - 2
f(2) = 10 - 2
Evaluate the difference
f(2) = 8
We continue by substituting 2 for n in the equation f(n + 1) = f(n) - 2
So, we have
f(2 + 1) = f(2) - 2
Evaluate the like terms
So, we have
f(3) = f(2) - 2
Substitute f(2) = 8 in f(3) = f(2) - 2
f(3) = 8 - 2
Evaluate the difference
f(3) = 6
Hence, the value of f(3) is 6

What is Right triangle?A right triangle, also known as a right-angled triangle, or more formally an orthogonal triangle, formerly known as a rectangle triangle, is a triangle with one right angle or two perpendicular sides. Trigonometry is founded on the relationship between the sides and other angles of a right triangle. A right-angled triangle exists a triangle in which one of the angles stands 90 degrees. The sum of the other two angles is 90 degrees. The sides that include the right angle are perpendicular and form the triangle's base. The third side is known as the hypotenuse, and it is the longest of the three sides.Therefore,
M = 30°, O = 60°, Q = 90°. Because this is a right angle triangle with angle 90°

After the distributive property, the expression is represented as follows:
9 x w + 9 x 5 = 9w + 45.
(the outer term 9 multiplies each of the inner terms, of w and 5, and then they are added, due to the plus sign).
Commutative propertyThe commutative property of addition states that the order of the terms of the addition is not important, hence:

For each graph, find the a. domain and range, b. positive and negative interval(s), and c. interval(s) of increasing and decreasing values.
A function's "positive regions" are those times when it is above the x-axis. Y-values that are positive are where it is (not zero). The portions of a function that are below the x-axis are known as its negative regions. Where the y-values are negative is there (not zero).
The interval widens if the function's first derivative is f' (x) 0.
On the other hand, the interval is referred to as a declining interval if the value of the derivative f' (x) 0.
How does negative interval work?The mean of the first population is higher than that of the second population for an interval range with exclusively positive values. The mean of the first population is lower than that of the second population for an interval range with only negative values.The range that the genuine difference in means falls within is shown by the 95% confidence interval. Because the difference in means could be negative, the CI can therefore include negative numbers.It is perfectly OK to replace the lower endpoint with zero if the lower endpoint of a confidence interval for a population percentage is negative because doing so does not reduce the level of confidence. A population percentage cannot be more than 100%, either.Only in the sense that, depending on the range of the data, one or more of the confidence interval's bounds (upper or lower) may be negative. The upper-lower interval will inevitably always be positive.To learn more about negative interval refer to:

Find the coordinate of the image of B (4, 0) after a reflection over the y-axis.
We need to know reflection of point about axes to solve the problem. The image of B (4,0) after reflection about y-axis is (-4,0).
Reflection about an axis means finding the point on the graph that is at an equal distance from the axis on the opposite side of the reflecting surface. The reflection can be about an axis or a line or origin. When a point is reflected about the x-axis, the sign of the y-coordinate of the point changes, when a point is reflected about y-axis the sign of the x-coordinate of the point changes and when a point reflects about the origin, the sign of both the coordinates change. Here in the question we need to find the reflection of point B (4,0) about y-axis, the image of point B will be (-4,0).

- If T is the midpoint of SU, what are ST, TU, and SU?
9x
6x=30
The midpoint of a segment is the point that divides the segment in half. Knowing this, we will receive:
ST = 90
TU = 90
SU = 180
Solution:A line segment's midpoint is a point that is halfway between two points. The midpoint is the same distance between the two ends.So here, if T is the midpoint of SU, we will have:
ST = TU
And we have terms for these measures:
ST = 9x
TU = 6x + 30
we can write it as:
9 x = 36 x + 30
Now solve this for x.
9x - 6 x = 30
3 x = 30
x = 30 / 3 = 10
x = 10
Now that we know what the value of x is, we can use it to solve the equations to determine the length of each segment:
ST = 9 x
= 9 × 10 = 90
TU = 6 x + 30
= 6 × 10 + 30 = 90
SU = ST + TU
= 90 + 90 = 180
ST = 90
TU = 90
SU = 180

The temperature at jebel jais at 6 a.m. will be -5 °C and the temperature at 9 a.m will be 1 °C.
What is temperature?A temperature is a unit of hotness or coldness that can be described in terms of a variety of arbitrary scales. It also indicates the direction in which heat energy will naturally flow, i.e., from a hotter body to a colder body (one at a lower temperature). Temperature is not the same as the energy of a thermodynamic system; for instance, an iceberg has a considerably higher temperature than a burning match, but it has a far larger total heat energy than a match.
According to the question,
The temperature at 5 a.m = -3 °C
The temperature at drops by 2 °C at 6 a.m = -3°C - 2 °C
The total temperature at 6 a.m = -5 °C
The temperature rises by 7 °C at 8 a.m.
The net temperature by 8 a.m = -5 °C + 7 °C = 2 °C
The temperature drops by 1 °C at 9 a.m.
The net temperature at 9 a.m = 2 °C - 1 °C = 1 °C
Hence, the temperature at 6 a.m is -5 °C and the temperature at 9 a.m is 1 °C.

If the divisor is a decimal then you must multiply by a power of 10 to make it a whole number. Why is it important to multiply the dividend and the divisor by the same power of 10? NEED HELP ASAP WILL GIVE BRAINLIST ALSO NO SAMPLE RESPONSE
In this example, the number being divided (15) is known as the dividend, and the number being divided by (3 in this instance) is known as the divisor. The quotient is the outcome of the division. Observe how 15 x 3 = 5 is a correct equation even if you change the quotient and divisor.
Explain about the divisor and dividend?The dividend appears to the right, or underneath, the division bracket, while the divisor is the number that appears to the left, or outside, of the division bracket.
An integer that divides another integer to obtain a result is called a divisor. The result of this division, or quotient, is the dividend, which is the original number that was divided. Quotient = Dividend Divisor.
To keep the divisor and dividend in the same proportion to one another, you multiply them by the same power.
This is true for division that is not decimal.
10 / 5 = 2.
Multiplying both sides by ten results in 100/50, which is still two.
If you merely divided by 10, you would get 100/5, which is equal to 20, or 10/50, which is equal to 1/5. Both of these throw off the ratio.
