What is estimate products?
Round the numbers to some nearby figures that you can mentally multiply to estimate the product of multiplication. Rounding all variables to the biggest digit (place value) they have is one way to estimate values.Example -Estimation is frequently accomplished through sampling, which involves counting a small sample of a given thing and extrapolating that number to a wider population. Calculating how many sweets of a certain size are contained in a glass jar is an example of estimation.203X12

B.15 x 40 = 40 x 15
C.15 + 40 = 55
D.15 + 40 = 5(3 + 8)
The option D.15 + 40 = 5(3 + 8); demonstrates the distributive property.
What is the meant by the term distributive property?To "distribute" something means to divide it or give a fraction or portion of it.The distributive property corresponds to the distributive law of multiplication over basic arithmetic operations such as addition and subtraction.This property states that multiplying a sum of two or even more addends by a number produces the same outcome as multiplying each addend separately by the number and afterwards adding the products together.In other words, the distributive property requires an expression of the form: A (B + C) can be written as AB + BC.This property also applies to subtraction: A (B - C) can be written as AB - BC.This indicates that other two operands share operand A.From the given options;
Consider option D; 15 + 40 = 5(3 + 8).
It is the case of distributive addition.
where
5(3 + 8) = 5×3 + 5×8
5(3 + 8) = 15 + 40
Thus, the option D is the correct representation of the distributive law.

Write the equation of the circle that passes through the given point and has a center at the origin. (Hint: You can use the distance formula to find the radius.) (-6,-4)
The equation of the circle that passes through the point (-6 , -4) and has a center located at the origin is x^2 + y^2 = 52.
Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (-6 , -4).
radius = distance = √(x2 - x1)^2 + (y2 - y1)^2
radius = √(-6 - 0)^2 + (-4 - 0)^2
radius= √36 + 16
radius = √52
The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.
(x - h)^2 + (y - k)^2 = r^2
where (h , k) = (0 , 0)
r = √52
(x - 0)^2 + (y - 0)^2 = (√52)^2

What is the sequence of AP arithmetic progression?In Arithmetic Progression, the difference between two different arithmetic orders is a fixed number (AP). Arithmetic Sequence is another name for it.
We'd come along through a few specific terms in AP that had been labeled as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)As shown below, the AP can also be referred to in terms of common differences.
The following is the procedure for evaluating an AP's n-th term: an = a + (n − 1) × dThe arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, as the values given in the question;
There are total 16 rows in the arena.
Thus, n = 16.
There are 20 seats present in row 1.
Consider the first term as 'a₁' = 20.
Similarly, there are 23 seats present at row 2.
Consider 'a₂' = 23 is the second term.
Now, calculate the common difference;
d = a₂ - a₁
Put the values in the 'd'.
d = 23 - 20 = 3.
Now, compute the total number of seats in 16th row bu nth formula.
n-th term: an = a + (n − 1) × d
a₁₆ = a₁ + (n - 1)d
a₁₆ = 20 + (16 - 1)3
a₁₆ = 20 + 45
a₁₆ = 65
Therefore, the total number of seats present in the 16th row is 65.

The figure is a value density curve because the area under the figure is of 1.
For itens b to d, the probabilities are also given by areas, hence:

It is given that the first bounce is of height [tex]6.5\; {\rm ft}[/tex]. Relative to this first bounce:
The [tex]n = 2[/tex] bounce is dampened [tex](2 - 1) = 1[/tex] time. The height of this bounce would be [tex]((0.78)\, 6.5)\; {\rm ft} = ((0.78)^{2 - 1} \, 6.5)\; {\rm ft}[/tex].The [tex]n = 3[/tex] bounce is dampened [tex](3 - 1) = 2[/tex] times. The height of this bounce would be [tex](0.78)\, ((0.78)\, 6.5)\; {\rm ft} = ((0.78)^{3 - 1} \, 6.5)\: {\rm ft}[/tex].In general, the [tex]n[/tex]th bounce would have been dampened [tex](n - 1)[/tex] times. The height of that bounce would be [tex]((0.78)^{n - 1}\, 6.5)\; {\rm ft}[/tex].
Thus, the [tex]10[/tex]th bounce would have been dampened [tex](10 - 1) = 9[/tex] times. The height of that bounce would be [tex]((0.78)^{10 - 1} \, 6.5)\; {\rm ft} \approx 0.7\; {\rm ft}[/tex] (rounded to the nearest tenth, one digit after the decimal point.)
