Step-by-step explanation:
1.5(2x - 5 ) - 2.5(3x + 8) -
= 3x - 7.5 - 7.5x - 20
= -4.5x - 27.5
How do you solve log2 value?.
The value of log 2 to the base 10 is 0.3010.
[tex]log_1_02[/tex] = 0.3010.
Now, According to the question:
The value of log 2, to the base 10, is 0.301. The log function or logarithm function is used in most mathematical problems that hold the exponential functions. Log functions are used to eliminate the exponential functions when the equation includes exponential values.
The logarithmic function is defined by:
if [tex]log_ab[/tex]= x, then [tex]a^x[/tex] = b.
Where,
x is the logarithm of a number ‘b.’
‘a’ is the base of the log function.
Now,
Let us discuss how to find the value of log 2 using a common log function and natural log function.
Value of [tex]log_1_02[/tex]
The log function of 2 to the base 10 is denoted by “ [tex]log_1_02[/tex]”.
According to the definition of the logarithmic function,
Base, a = 10 and [tex]10^x[/tex]= b
With the use of logarithm table, the value of log 2 to the base 10 is given by 0.3010.

What is congruent of the triangle?
The shapes maintain their equality regardless of how they are turned, flipped, or rotated before being cut out and stacked. We'll see that they'll be placed entirely on top of one another and will superimpose one another. Due to their identical radius and ability to be positioned directly on top of one another, the following circles are considered to be congruent.
Any two figures can be perfectly positioned over one another to demonstrate their congruence. The relationship between two figures that are said to be congruent is described using the word "congruence."
As both the triangles are right angle so the left side triangle the angles are 90, 54 and 38.

(b) On that date, how many pesos was 98.27 dollars worth? >Round your answer to the nearest hundredth of a peso. 0 pesos
Answer:
(a) 7.68 dollars
(b) 1927.07 pesos
Step-by-step explanation:
Setting up a conversion factor will be helpful in helping us solve this problem. A conversion factor shows the relationship between two different units, and and is used to convert from one unit to the other.
Our conversion factor is 1 U.S. Dollar = 19.61 Mexican pesos. To convert units, we can turn the conversion factor into a ratio (U.S. dollar ÷ 19.61 Mexican pesos or vice versa) and then multiply the given amount by the ratio. The unit that we want to end up with should always be in the numerator, and the unit we want to convert from should always cancel out in the denominator. This will be demonstrated when we solve the problems below:
(a) We want to convert from pesos to dollars, so we will multiply by the conversion factor (1 dollar / 19.61 pesos).
150.68 pesos (1 dollar / 19.61 pesos) = 7.68 dollars(b) Now we want to convert from dollars to pesos, so we will multiply by the conversion factor (19.61 pesos / 1 dollar).
98.27 dollars (19.61 pesos / 1 dollar) = 1927.07 pesosWhat characteristics of parallel lines and perpendicular lines create different requirements?.

The length of a rectangular prism is 2 more than three times the width w. The volume of the prism is 3w^3+14w^2+8w.[tex]3w^{3} +14w^{2} +8w[/tex] What is a simplified expression for the height of the prism?
The volume of a rectangular prism is given by the product of its length, width, and height, which is V = l * w * h, where l is the length, w is the width, and h is the height.
We are given that the volume of the prism is 3w^3 + 14w^2 + 8w. We can use this information to find the height of the prism by dividing the volume by the product of the length and width.
We know that the length of the prism is 2 more than three times the width (l = 3w + 2). Therefore, the product of the length and width is l*w = (3w + 2) * w = 3w^2 + 2w
Now we can divide the volume by the product of the length and width to find the height of the prism:
V / (l * w) = (3w^3 + 14w^2 + 8w) / (3w^2 + 2w) = 3w + 14 + 8/3w^2 + 2w
So, the height of the prism is 3w + 14 + 8/3w^2 + 2w
Which is a simplified expression for the height of the prism, in terms of the width.

Answer:
√21 is irrational
Step-by-step explanation:
√21 = 4.58257569495584 which is a non-terminating decimal.
Therefore √21 is irrational.
Answer: No, it cannot be a rational number.
Step-by-step explanation:
A rational number is defined to be a whole number (ex. 1, 2, 3) or can be decimals that continuously repeat the digits after the point. In the case of a square root, they can be rational--but this only applies to perfect squares: √100, √64, √16, etc, which would give an outcome of a whole number. Therefore, √21 is not a rational number, as the decimal value is 4.57257, and is not continuous (ex. 3.666666).
