Where the information relating to the circle and its diameter are given, the equation of the circle would be: "(x 5)² + y2 = 81" (Option B)
Why is this so?The above is determined by the standard form equation of a circle which is:
(x- h) ² + (y - k)² = r²
Here,
(h, k) is the center of the circle and r is the radius
In this case, the center is (-5 , 0) and the diameter is 18, so the radius is half the diameter, whic is 18/ 2 = 9
So making the required substitutions, the expression becomes:
(x-(-5))² + (y-(0))² = 9²
Which becomes
(x 5)² + y2 = 81
Thus, it is correct to state that Option B is the equation of the circle.

If m varies jointly as p and the square root of w and m=21 when p=5 and w=36, find m when p=9 and w=225
When p = 9 and w = 225, the value of m is 94.5
How to find the value of m?We know that m varies jointly as p and the square root of w, then we can write.
m = k*p*√w
Where k is a constant.
We know that m=21 when p=5 and w=36, replacing that we will get:
21 = k*5*√46
21 = k*30
21/30 = k
7/10 = k
Then the equation is:
m = (7/10)*p*√w
Then when p = 9 and w = 225 we will have:

Krell Industries has a share price of $22.08 today. If Krell is expected to pay a dividend of $0.98 this year, and its stock price is expected to grow to $24.98 at the end of the year, what is Krell's dividend yield and equity cost of capital?
what is Krell's equity cost of capital, or expected total return ?
Krell's equity cost of capital, or expected total return, is 5.57%.
We have,
The dividend yield is the annual dividend divided by the current share price:
Dividend yield
= Annual dividend / Share price
= $0.98 / $22.08 = 0.0444 = 4.44%
The equity cost of capital is the expected total return on the stock, which includes both the dividend yield and the expected capital appreciation:
Equity cost of capital = Dividend yield + Capital Appreciation
= 4.44% + [(24.98 - 22.08) / 22.08]
= 4.44% + 0.1314
= 5.57%

Find the x - and y -intercepts of the following equation: 3x-2y=5 ?
The x-intercept will be (5/3, 0) and the y-intercept will be (0, -5/2).
The x-intercept of an equation is the point at which the graph of the equation intersects the x-axis, which means that the y-coordinate of that point is 0. To find a x-intercept, we can set y = 0 in equation and solve for x.
Given the equation: 3x - 2y = 5
Setting y = 0, we get;
3x - 2(0) = 5
3x = 5
x = 5/3
So, the x-intercept is (5/3, 0).
The y-intercept of an equation is the point at which the graph of the equation intersects the y-axis, which means that the x-coordinate of that point is 0. To find y-intercept, we can set x = 0 in equation and solve for y.
Setting x = 0, we get;
3(0) - 2y = 5
-2y = 5
y = -5/2
So, the y-intercept is (0, -5/2).

Answer:d
Step-by-step explanation:
Lois is planning to retire from her job. She has been working there for 27 years. If she retires this year, her monthly pension will be calculated with a flat benefit formula using the flat amount of $52 for each year of
service. She was informed that if she works another 4 years that the flat amount would increase to $60 for each year of service. How much more would her pension be if she waited the 4 years?
If Lois is retiring from her job after 27 years, then if she waited for 4 years, her pension will be $38 higher than if she retires this year.
If Lois retires this year, the flat-amount is $52, So, her monthly pension can be calculated as follows;
⇒ Monthly pension = (52 × 27)/12,
⇒ Monthly pension = $117,
If Lois works for another 4 years, the flat amount used to calculate her monthly pension will increase to $60 for each year of service.
So, her monthly pension will be calculated as follows:
⇒ Monthly pension = (60 × 31)/12,
⇒ Monthly pension = $155,
So, The difference in monthly pension between retiring this year and retiring after working another 4 years can be calculated as follows:
⇒ Difference in monthly pension = $155 - $117,
⇒ Difference in monthly pension = $38,
Therefore, if Lois waits another 4 years before retiring, her monthly pension will be $38 higher than if she retires this year.

Triangle LMN is an obtuse triangle with l = 6, n = 8.3, and m∠M = 132°. What is the area of ΔLMN?
The area of triangle LMN is 49.61 square units.
We have,
To find the area of triangle LMN.
Area = (1/2) x base x height
where the base and height are the sides of the triangle perpendicular to each other.
First, we need to find the length of side L.
We can use the Law of Cosines.
L² = M² + N² - 2MNcos(132°)
L² = 6² + 8.3² - 268.3cos(132°)
L² = 36 + 68.89 + 99.36
L² = 204.25
L = √204.25
L = 14.28
Now that we know the length of the base of the triangle, we can find the height by dropping a perpendicular from vertex M to side LN.
Since triangle LMN is obtuse, the perpendicular will fall outside of the triangle.
Let's call the foot of the perpendicular point P.
Since M∠M is 132°, we can find the measure of the acute angle ∠LMP:
M∠LMP = 180° - M∠M
M∠LMP = 180° - 132°
M∠LMP = 48°
We can use trigonometry to find the length of MP:
tan(48°) = h/6
h = 6 x tan(48°)
h = 6.93
The area of triangle LMN is:
Area = (1/2) x base x height
Area = (1/2) x 14.28 x 6.93
Area ≈ 49.61
Thus,
The area of triangle LMN is 49.61 square units.

A college student takes the same number of credits each semester. Before beginning college, the student had some credits earned while in high school. After 2 semesters, the student had 39 credits, and after 5 semesters, the student had 75 credits.
If C(t) is the number of credits after t semesters, write an equation that represents this situation.
Provide your answer below:
The equation that represents the number of credits the student has earned after t semesters is C(t) = 12t + 15.
Let x be the number of credits the student had before starting college, and let y be the number of credits the student takes each semester. We can use this information to write an equation that represents the number of credits the student has earned after t semesters.
After 2 semesters, the student had 39 credits, which means the student earned 2y + x credits in those two semesters. Similarly, after 5 semesters, the student had 75 credits, which means the student earned 5y + x credits in those five semesters.
Using this information, we can write the following equation:
C(t) = yt + x
where C(t) represents the number of credits the student has earned after t semesters.
We know that C(2) = 2y + x = 39 and C(5) = 5y + x = 75. We can use these two equations to solve for x and y:
2y + x = 39
5y + x = 75
Subtracting the first equation from the second equation gives:
3y = 36
Therefore, y = 12, which means the student takes 12 credits each semester. Substituting y = 12 into either of the two equations above gives x = 15, which means the student had 15 credits before starting college.
Thus, the equation that represents the number of credits the student has earned after t semesters is C(t) = 12t + 15.
