Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(5)
x² + (y - 4)² = 25 ← is in standard form
with centre = (h, k) = (0, 4) → A
(6)
here (h, k) = ( 9, - 5) and r = 1, hence
(x - 9)² + (y - (- 5))² = 1², that is
(x - 9)² + (y + 5)² = 1 ← equation of circle

0.0006=6x10^-4
Since the exponent is negative, the number will get smaller. A negative exponent shows that the decimal point is shifted that number of places to the left. The exponent is -4, so the decimal place will move 4 places to the left.
Answer:
0.0006
Step-by-step explanation:
A number in scientific notation if it has the form a × 10ⁿ.
A negative exponent indicates
A number between 0 and 1. That the decimal point is shifted that number of places to the left.6 × 10⁻⁴ tells you that the decimal number is 6. with the decimal point moved four places to the left.
Thus, 6 × 10⁻⁴ becomes 0.0006

The company wants to maximize its profits by using the objective function P = 2x + 2.5y
What is the maximum profit.

106
Answers
Answer:
Fourth option
Step-by-step explanation:
When graphing the given inequalities you will get a region like the one shown in the attached image. This region is delimited by 4 straight
[tex]x = 0\\\\y = 0\\\\9x + 6y = 400\\\\7x + 10y = 400[/tex]
The points indicated at the ends of the region are the maximum possible values of x and y.
We must test these points in the objective function [tex]P = 2x + 2.5y[/tex] and see which point maximizes the value of P.
Remember that the boundaries of the region are not included.
We can prove the point x = 0 and y = 39 because (0,4) is not included in the region.
[tex]P = 2(0) + 2.5(39) = 97.5[/tex]
Now we test the point x = 33 and y = 16
[tex]P = 2(33) + 2.5(16) = 106[/tex]
Now we test the point x = 44 and y = 0
[tex]P = 2(44) + 2.5(0) = 88[/tex]
Finally the optimal value is:
x = 33 oz
y = 16 oz

Answers
Total students in the class who got the quiz = 28
The average of the class average was = 82.5
Five students that were absent made up the quiz after school and their scores were a 78, 89,92,99, & 63.
The formula for an average= (sum of values) / (count of values)
As the average is given as 82.5 and there were 28 students, so sum of the 28 values will be = [tex]28\times82.5=2310[/tex]
Total students of the class = 28+5(absent) = 33
For 33 students the total score was = 2310 +(78+89+92+99+63)
= 2731
So, average for 33 students will be = [tex]\frac{2731}{33} =82.757[/tex] or 82.76
So, the new class average is 82.76

What is the solution to the following system of linear equations? 4y − 36 = −12x 3x + y = −9 Select one: A. (-2, 3) B. (1, 5) C. no solution D. infinitely many solutions
Answers
I think it's c. No solution
The solution for the given system of linear equations is (1, -2), which is not provided in the options given. A possible typo may exist in the options.
Explanation:This question is asking for the solution to a system of linear equations. The equations were given as 4y − 36 = −12x and 3x + y = −9. To solve this system, we can use the method of substitution or elimination. First, let's rewrite the first equation in terms of x. Dividing each side of 4y - 36 = -12x by -12, we get x = -y/3 + 3. We can then substitute (-y/3 + 3) for x into the second equation, yielding 3(-y/3 + 3) + y = -9. Solving Yields y = -2 and substituting y = -2 into x = -y/3 + 3 gives x = 1. So, the solution to this system is x = 1, y = -2. So the correct answer is (1, -2), which was not provided in the options. It seems there might be a typo in the options provided.

suppose you are in your last semester of college and have a 2.75 GPA after 105 credit hours if you are taking 15 credit hours in your last semester and get a perfect 4.0 GPA what will your overall GPA be is it possible to get your GPA up to 3.0 for the graduation
Answers
Answer:
The overall CGPA would be 2.90 so it is not possible for hum to secure a CGPA of 3 for graduation.
Step-by-step explanation:
Given,
CGPA = 2.75
Credit hours = 105
Last semester GPA = 4
Last semester credit hours = 15
CGPA = [tex]\frac{sum of (Credit hours of each subject * GPA of each subject)}{Total credit hours}[/tex]credit hours * gpa
in our case, it would be:
CGPA = [tex]\frac{(2.75*105)+(4*15}{105+15}[/tex]
=> [tex]\frac{(288.75)+(60)}{120}[/tex]
=> [tex]\frac{348.75}{120}[/tex]

Answers
Among the given options, statement D, which says 'For every man who likes running, 7 men like playing golf,' is the correct statement based on the numbers provided.
Explanation:In order to determine which statement is correct, we would need to relate the numbers given in the question. So let's take a look.
We have 14 men who like playing golf and 2 men who like running. So for each man that likes running, there are 14/2 = 7 men who like playing golf.We have 6 women who like playing golf and 18 women who like running. So for each woman that likes running, there are 6/18 = 1/3 women who like playing golf. This does not match either statement A or B. So we can rule them out.With this comparison, we can conclude that the correct statement is D. For every man who likes running, 7 men like playing golf.

Albert buys a car for $12,000. The value of the car depreciates about 9% per year. After about how many years will the car be worth $7500?
Answers
Answer:

Step-by-step explanation:
we know that
The formula to calculate the depreciated value is equal to
[tex]D=P(1-r)^{t}[/tex]
where
D is the depreciated value
P is the original value
r is the rate of depreciation in decimal
t is Number of Time Periods
in this problem we have
[tex]P=\$12,000\\r=9\%=0.09\\D=\$7,500[/tex]
substitute in the formula above and solve for t
[tex]\$7,500=\$12,000(1-0.09)^{t}[/tex]
[tex](7,500/12,000)=(0.91)^{t}[/tex]
Apply log both sides
[tex]log(7,500/12,000)=t*log(0.91)[/tex]
[tex]t=log(7,500/12,000)/log(0.91)=5\ years[/tex]
