The expression given to us is:
[tex] 9m^2-\frac{6}{5}m+c [/tex]
If the above expression is a perfect square then the middle term will have to be 2 times the square root of the first term times the square root of the last term. Thus:
[tex] -\frac{6}{5}m=2\times 3m\times \sqrt{c} [/tex]
[tex] \therefore \sqrt{c}=-\frac{1}{5} [/tex]
Thus, [tex] c=\frac{1}{25} [/tex]
Thus, for 9m^2-(6/5)m+c to be a perfect square, the value of c must be equal to [tex] \frac{1}{25} [/tex] or 1/25

Manny Brought a brand new car in 2012 for $28750. if the car depreciates by 12% each year, write n exponential function to model the situation, then find the value of the car in 2018
Value of the car in 2018 after depreciation by 12% each year is equals to $13351.5
What is exponential decay?" Exponential decay is the decrease in the value of the product at a constant rate over a period of time interval."
Formula used
y = a (1 - r)ⁿ
a = Initial value
r =rate of depreciation
n = time
y = exponential function
According to the question,
Cost of new car 'a' = $28750
Rate of depreciation 'r' = 12%
2018 - 2012 = 6years
n = 6
Substitute the given values in the formula we get,
Exponential function
y = 28750 [1 - (12 / 100)]⁶
⇒ y = 28750 ( 1 - 0.12)⁶
⇒ y = 28750 ( 0.88)⁶
⇒ y = 28750 (0.4644) ( up to four decimals)
⇒ y = $13351.5
Hence, value of the car in 2018 after depreciation by 12% each year is equals to $13351.5

The engine of a car has a displacement of 305 cubic inches. what is the displacement in cubic feet? round your answer to 2 decimal places.
Answer:
0.18 cubic feet (in 2 decimal places)
Step-by-step explanation:
The relationship between the unit of measurement inches and the unit of measurement feet may be expressed mathematically as
12 Inches = 1 feet
finding the cube of both sides i.e both sides to the power of 3,
1728 cubic inches = 1 cubic feet
therefore,
305 cubic inches
= 305/1728 cubic feet
= 0.1765 cubic feet

Solution:
Wyatt's dog is tethered to a post in his yard.
The rope tied to the dog is 12 feet long.
we have been asked to find
How many square yards does the dog have access to?
when Wyatt's dog is tethered to a post in his yard, then that dog can move along that post only and the area covered will be a circle with radius 12ft.
So Area access to dog in ft^2 [tex] = \pi r^2=\pi 12^2=144 \pi [/tex]
But it ask for area in yards, so we will have to use conversion formula

A negative correlation means that ________. select one:
a. high values of one variable are associated with low values of the other
b. high values of one variable are associated with high values of the other
c. low values of one variable are associated with low values of the other
d. there is no relationship between the two variables
A negative correlation means that high values of one variable are associated with low values of the other. This suggests that as one variable increases, the other decreases respectively and vice versa, which can be seen in various real-world scenarios such as the relationship between time spent studying and number of mistakes made on a test.
Explanation:In the context of statistics and data analysis, a negative correlation means that high values of one variable are associated with low values of the other. This implies that as one variable increases, the other decreases correspondingly and vice versa. For instance, if we were examining the relationship between time spent studying and number of mistakes made on a test, a negative correlation might indicate that the more time a student spends studying, the fewer mistakes they make on the test. This is indicative of a negative correlation because as the value of one variable (study time) increases, the value of the other variable (mistakes) decreases.

Divide. 5x3y3z - 6x4y2z2 + 4xy3z xyz
Final Answer:
The result of dividing [tex](5x^3y^3z - 6x^4y^2z^2 + 4xy^3z)[/tex] by xyz is [tex](5x^2y^2 - 6x^3yz + 4y^2z).[/tex]
Explanation:
To divide [tex](5x^3y^3z - 6x^4y^2z^2 + 4xy^3z)[/tex] by xyz, we'll divide each term in the polynomial by xyz separately.
First, let's divide [tex]5x^3y^3z by xyz: (5x^3y^3z) / (xyz) = 5x^2y^2.[/tex]
Then, divide [tex]-6x^4y^2z^2 by xyz: (-6x^4y^2z^2) / (xyz) = -6x^3yz.[/tex]
Lastly, divide [tex]4xy^3z by xyz: (4xy^3z) / (xyz) = 4y^2z.[/tex]
Thus, the resulting polynomial after division is [tex]5x^2y^2 - 6x^3yz + 4y^2z.[/tex]This is derived from individually dividing each term in the polynomial by xyz, simplifying each term, and collecting like terms together to obtain the final result.
In this process, division by xyz means dividing each term of the polynomial by the factors x, y, and z, and simplifying the expression. By doing so, we obtain a simplified form of the polynomial where each term is reduced by the common factors x, y, and z, resulting in the expression [tex](5x^2y^2 - 6x^3yz + 4y^2z)[/tex] as the quotient.
Complete question:

Aldo drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 8 hours. When Aldo drove home, there was no traffic and the trip only took 5 hours. If his average rate was 21 miles per hour faster on the trip home, how far away does Aldo live from the mountains? Do not do any rounding.
The distance of Aldo's house from the mountains when calculated using the parameters is; 280 miles
How to Solve Algebra Word Problems?We know that distance is given by;
Distance = speed * time
Distance with traffic = 8x
Distance without Traffic plus average rate = 5(x + 21)
Thus;
8x = 5(x + 21)
8x = 5x + 105
3x = 105
x = 105/3
x = 35
Thus;
Distance from his house = 5(35 + 21) = 280 miles
