the population will reach 8 billion by 2012 ,as calculated by properties of logarithm.
What is Logarithm?The opposite of exponentiation is the logarithm.This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.Given:
y = 6.72 ( [tex]1.014^x[/tex]), wherey = population in billionsx = time in yearsTo find: Year when population is 8 billion, i.e., y = 8.
Finding:
8 = 6.72 ( [tex]1.014^x[/tex])
=> [tex]\frac{8}{6.72}= ( 1.014^x)[/tex]
Taking log on both sides
=> [tex]log(\frac{8}{6.72})= log( 1.014^x)[/tex]
=> log(1.19) = x (log 1.014) (as [tex]log_b(a)^m = m (log_b(a))[/tex] )

The equation says x - 0.8 divided by 1.2 = 6 This is a multi step with decimals find the x equation
The value of x in the equation (x – 0.8) / 1.2 = 6 is 8.
Given,
The equation = (x – 0.8) / 1.2 = 6
We have to expand this equation and find x.
That is,
(x – 0.8) / 1.2 = 6
Multiply 1.2 both sides.
(x – 0.8) x (1.2) / 1.2 = 6 x 1.2
(x – 0.8) = 6 x 1.2
(x – 0.8) = 7.2
Shift 0.8 to right hand side
Then we get,
x = 7.2 + 0.8
x = 8

The measure of an angle's supplement is 51 degress less than the measure of the angle. Find the measures of the a and its supplement
Step-by-step explanation:
supplementary angles mean that they are together 180°.
so,
a + (a - 51) = 180
2a - 51 = 180
2a = 231
a = 115.5°
its supplement is 180 - 115.5 = 64.5°
The measure of the angle's supplement is 64.5 degrees.
Let's denote the measure of the angle as "a" degrees. The supplement of an angle is the angle that, when added to the given angle, results in a total of 180 degrees (because the sum of angles in a straight line is 180 degrees).
According to the problem, the measure of the angle's supplement is 51 degrees less than the measure of the angle. Mathematically, we can express this as:
Supplement angle = Angle - 51
Since the sum of the angle and its supplement is 180 degrees, we can write the equation:
Angle + Supplement angle = 180
Substitute the expression for the supplement angle:
a + (a - 51) = 180
Combine like terms:
2a - 51 = 180
Now, solve for "a":
2a = 180 + 51
2a = 231
a = 231 / 2
a = 115.5
So, the measure of the angle "a" is 115.5 degrees.
Now, to find the supplement angle:
Supplement angle = a - 51 = 115.5 - 51 = 64.5
Therefore, the measure of the angle's supplement is 64.5 degrees.

In this question we have been given a parallelogram LMNO
The diagonals of parallelogram LMNO intersect at point P.
The diagonals of parallelogram LMNO are LN and MO.
The point P divides each diagonal into exactly two equal parts.

Simplify each radical expression. Use absolute value symbols when needed. √9x⁴/ 36
The value of the given expression √9x⁴/ 36 in simplified form is x² / 2.
By canceling it with its common factors, we must create this expression in its most basic form.So, we have to make this expression √ 9x⁴ / 36 in its lowest form by cancelling it with its common factors.√ 9x⁴ / 36
Take 9 from this since the common factor is 9.= √ 9 x⁴ / 9*4
= √ x⁴ / 4
We must now rewrite it as follows:4 = 2*2 = ( 2 )² and x⁴ = x² * x² = ( x² )²
As a result, the square root of x⁴ is x².Moreover, 2 is the square root of 4.hence, √ x⁴ / 4 = ( x² / 2 )²

What is Straight line?
A line with no curve is called a straight line.
Given that;
One endpoint of a line = (-3, 7)
Midpoint of a line = (5, 2).
Now, Let the other endpoint of a line = (x, y)
Then, Other endpoint is solve by the definition of midpoint of two points as;
(x + (-3) / 2 , y + 7 / 2 ) = (5, 2)
(x - 3 / 2 , y + 7 / 2) = (5, 2)
By compare we get;
x - 3/ 2 = 5
x - 3 = 2 * 5
x - 3 = 10
x = 10 + 3
x = 13
And,
y + 7 / 2 = 2
