Use the properties of logarithms to evaluate each expression. log₉27-log₉9
The result of the given logarithmic expression log₉27-log₉9 is log₉ 3.
What is termed as logarithms?A logarithmic term is one that embodies a number in logarithmic form. It can also be referred to as a log term.
A quantity is also the product of two or more quantities. As a result, a term could be the product of two or even more quantities, at least one of which can be in logarithmic form. In such cases, the terms are referred to as log terms.
A quantity is also the quotient of two quantities. So, if a term is also a quotient of quantities, and at least one of the quantities can be expressed in log form, the terms are mathematically referred to as log terms.
Quotient Rule: ㏒(A/B) = ㏒A - ㏒BProduct Rule : ㏒A + ㏒B = ㏒(AB)Power Rule: n㏒A = ㏒AⁿBase Rule = ㏒ₐb = ㏒ₓb/㏒ₓaExponent Rule = e∧lnx = xNow, as per the given question;
= log₉27-log₉9
So, applying the Quotient Rule in the given expression;
= log₉ (27/9)
= log₉ 3
Thus, the given expression simplified in the logarithmic expression as log₉ 3.

A logging company is funding a study to determine the best practice for reforesting a cut section of forest. the previous best practice has been to plant the same type of tree with equally spaced intervals. the proposed method of reforestry is to plant a variety of trees at differing intervals. in the study, some tracts of land are reforested using the previous best practice. what are these tracts of land in the study?
The tracts of land in the study is the Control group.
The tracts of land in the study are reforested using the previous best practice whose results are already known. Now, it is not known, how the proposed method of reforestrey to plant a variety of trees at different intervals would grow. So, the tracts of land of previous plant can serve as a standard to which comparisons can made as to whether the newly proposed method is performing better than the previous or not.
This study was conducted at the Agua Salud Project site located in the Panama Canal Watershed (9° 13 N′, 79° 47′ W, 33 m amsl) with an average rainfall of 2700 mm annually, 80% of which falls between May and mid-December. Mean daily maximum and minimum temperatures are 32 °C and 23 °C . The topography is characterized by short and steep slopes. Soils are silt clay to clay with pH values of 4.4 to 5.8 and have very low levels of both plant available and total phosphorus. The data were collected from the Agua Salud native species and T. grandis plantation, both established in 2008 and planted in the same 3 m by 3 m spacing configuration.
Despite this information, changing landowners’ perceptions and transitioning from one species to a lesser known one, is a risk for the landowner and may require financial incentives.

|14c+5|>7
How can I graph this?
Answer:
Step-by-step explanation:
step 1: Absolute value inequality entered
|14c+5| > 7
step 2: Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |14c+5|
For the Negative case we'll use -(14c+5)
For the Positive case we'll use (14c+5)
step 3: -(14c+5) > 7
Multiply
-14c-5 > 7
Rearrange and Add up
-14c > 12
Divide both sides by 14
-c > (6/7)
Multiply both sides by (-1)
Remember to flip the inequality sign
c < -(6/7)
Which is the solution for the Negative Case
step 4:
(14c+5) > 7
Rearrange and Add up
14c > 2
Divide both sides by 14
c > (1/7)
Which is the solution for the Positive Case
c < -6/7
c > 1/7

Step-by-step explanation:
There are 3 points on a line A, B and C.
If B is between A and C what is the length of BC.
AB= x²-6x
BC= x²+20x
AC= 60-12x
Given :
B is between A and C
AB= x²-6x
BC= x²+20x
AC= 60-12x
B divide into 2 equal parts
AB and AC are equal
AC = AB +BC
60-12x = x²-6x + x²+20x
[tex]60= 2x^{2} -6x +20x +12x[/tex]
[tex]60 = 2x^{2} -6x +32x\\[/tex]

The linear equation of the table is y = 5x + 2.
when x = 20, y = 102
when y = 42, x = 8
How to find the linear equation that generates the table?Linear equation can be represented in slope intercept form as follows;
y = mx + b
where
m = slopeb = y-interceptTherefore,
m = 17 - 12 / 3 - 2
m = 5 / 1
m = 5
Therefore, let's find the y-intercept using (2, 12)
y = 5x + b
12 = 5(2) + b
12 = 10 + b
b = 12 - 10
b = 2
Therefore, the linear equation is y = 5x + 2.
when x = 20
y = 5(20) + 2 = 100 + 2
y = 102
when y = 42
42 = 5x + 2
42 - 2 = 5x
5x = 40
x = 40 / 5
x = 8

F=GmM/r^2 solve for G
Solution of the equation for G is given as G = Fr²/Mm
According to the question we have been given the formula for evaluating the value of F which is given as :
F = GmM/r²
Now we need to solve the equation for evaluating G. Which is given step by step as :
F = GmM/r²
Multiplying both the sides by r² we get
Fr² = GmM*r²/r²
Fr² = GmM
dividing both the sides by Mm we get
Fr²/Mm = GmM/Mm
Fr²/Mm = G
or, G = Fr²/Mm
Hence the solution for G is given as G = Fr²/Mm

Write the slope-intercept equation for a line that passes through the points (-2, 4) and (3, -5)
The slope intercept equation for a line that passes through the points (-2,4) and (3,-5) is y = -9/5x ₊ 2/5.
Given the points are:
P₁ = (-2,4) = (x₁ , y₁)
P₂ = (3,-5) = (x₂ , y₂)
Therefore, the equation of the line that passes through the above points is:
y = mx ₊ b , Will be the equation to arrive to at the very end, but we need m & b, the slope and the y-intercept.
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
= ( -5 - 4 ) / ( 3 - ( -2) ) = -9 / 5
∴ m = - 9/5
Using either P₁ or P₂, plug in one of their respective x- and y-values into:
y = -9/5 x + b
substitute (3,-5)
₋5 = (₋9/5)(3) ₊ b
₋5 = ₋27/5 ₊ b
₋5₊27/5 = b
₋ 25 ₊ 27/5 = b
b = 2/5
slope intercept equation:
y = mx ₊ b
y = -9/5x ₊ 2/5
Therefore, y = -9/5x ₊ 2/5 is the equation of the line that passes through both points (-2, 4) and (3, -5).

A gardener can care for the greens property in 5 hours. if his helper assists him, they will be done in 4 hours. how many hours does it take for the helper to do it alone
If a gardener can care for the greens property in 5 hours and if his helper assists him, they will be done in 4 hours, then the number of hours it takes for the helper to do it alone is equal to 20.
The number of hours it takes for the helper to do it alone can be found as follows;
Time taken by both the gardener and the helper to complete the job=4
Work done by both the gardener and the helper in one hour = 1/4
Similarly,
Time taken by the gardener to complete the job = 5
Work done by the gardener in one hour = 1/5
The number of hours it takes for the helper alone can be calculated by subtraction. Subtracting the fraction done by the gardener in 1 hour from the fraction done by both the gardener and the helper in 1 hour;
1/4 - 1/5
As the common denominator is 20, we multiply 1/4 by 5 and 1/5 by 4.
5/20 - 4/20 = 1/20
The number of hours it takes for the helper to do it alone can be found by finding the reciprocal of 1/20 which is equal to 20/1
20/1 = 20
Hence, the helper takes 20 hours to do it alone.

The evaluation of the expression given in surd form is 6.
What is the evaluation of the surd form?Surds are expressions that use a root symbol, such as a square root, or another root symbol. Since the decimals of irrational numbers do not finish or recur, they cannot be expressed accurately in decimal form, hence surds are used instead.
Surds, in mathematics, are square root values that cannot be factored into a whole number or an integer. Numbers that are surds are irrational numbers.

Answer: I believe A is 52 degrees.
Solution: Find angle c (D + C adds up to 180 degrees cuz its a line)
So do 180-116=64 degrees
Assuming this is an isosceles triangle because the sides on d and c look equal, we know that those 2 angles add up to 128 degrees(64 + 64).
Therefore, since the shape is a triangle(adds up to 180 degrees) you just do 180 minus 128 to get angle A which is 52 degrees.
