Answer:
2118 dollars
Step-by-step explanation:
His capital gain is the difference in the (sell - buy) prices multiplied by the number of shares (120).
120 * (85.89 - 68.24) = 120 * 17.65 = 2118
The capital gain is a short term gain (held under a year)
The amount is 2118 dollars.
What is the maximum number of possible solutions for the system shown below?
[tex]x^2+4y^2=64\\x+y=5[/tex]
Answer:
2
Step-by-step explanation:
The first equation is that of a an ellipse. The second equation is that of a line.
Attached is the graphs of both of these equations.
If you think about it, there can only be 2 possible ways of solutions (intersection points) of an ellipse and a line.
1. The line will not intersect the ellipse at all, so no solution
2. The line will intersect the ellipse at 2 points maximum
So, we can clearly see from the reasoning that the maximum number of possible solutions would be 2. The graph attached confirms this as well.
Answer:
The maximum number of solutions that the system can have are 2
Step-by-step explanation:
We have a system of equations composed of an ellipse of equation [tex]x ^ 2 + 4y ^ 2 = 64[/tex] and a line of equation [tex]x + y = 5.[/tex]
The solution to the system of equations gives information about when the values of both equations coincide. In other words, the solutions of the system of equations give information about the number of times that the line [tex]x + y = 5[/tex]. touch or intercept the graph of the ellipse [tex]x ^ 2 + 4y ^ 2 = 64[/tex]
Graphically you can verify that a line can only touch an ellipse once or can intercept an ellipse a maximum of two times, or never touch it
Therefore, the maximum number of solutions that the system can have are 2.

ANSWER
B. y=8x +1200
EXPLANATION
If the family's well pumps on average 8 gallons of water per minute, then the unit rate of change is 8.
This implies that, the slope of the linear equation that models this situation is
[tex]m = 8[/tex]
It was also given that, the well's tank had 1200 gallons of water in the morning.
This implies that the y-intercept of the straight line is
[tex]b = 1200[/tex]
The equation is given by:
[tex]y = mx + b[/tex]
We substitute the values to obtain:
[tex]y = 8x + 1200[/tex]
The amount of water in the tank, y after it has been pumping for x minutes is
[tex]y = 8x + 1200[/tex]

A.) 9.0 yd
B.) 15.6 yd
C.) 31.2 yd
D.) 10.4 yd
the answer will be B
Answer:
D.) 10.4 yd
Step-by-step explanation:
In the given figure the alternate angles are equal and hence a right angle triangle with one of its angle as 30 degree is formed .
For angle 30 degrees adjacent side is 18 yard and opposite side is x.
Tan of an angle is equal to [tex]\frac{opposite}{adjacent}[/tex]
[tex]Tan 30=\frac{x}{18}[/tex]
x=Tan 30 (18)
x= 10.39
x= 10.4 yard (rounded to tenth place)

When two six-sided dice are rolled, there are 36 possible outcomes. a. Find the probability that the sum is not 4. Express your first answer as a fraction in simplest form, and round your percent answer to the nearest whole percent. b. Find the probability that the sum is greater than 5. Express your first answer as a fraction in simplest form, and round your percent answer to the nearest whole percent. Round the fraction
The probability of not getting a sum of 4 when rolling two six-sided dice is 33/36 or 92%. The probability of getting a sum greater than 5 when rolling two six-sided dice is 13/18 or approximately 72%.
Explanation:The subject area for this question is in Mathematics, specifically probability. The question asks to determine the probability of a sum not being 4, and of a sum being greater than 5 when two six-sided dice are rolled.
(a) The possibilities of getting a sum of 4 are (1,3), (2,2), and (3,1). That's 3 possibilities out of a total of 36, therefore the probability of not getting a sum of 4 is 1 - (3/36) = 33/36 (in simplified form) and as a percentage that's approximately 92%.
(b) The possibilities of getting a sum greater than 5 are (2,4),(3,3),(3,4),(4,2),(4,3),(4,4),(1,5),(2,5),(3,5),(4,5),(5,1),(5,2),(5,3),(5,4),(5,5),(1,6),(2,6),(3,6),(4,6),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5), and (6,6). That's 26 possibilities out of 36, therefore the probability of getting a sum greater than 5 is 26/36 or 13/18 in simplest form, and as a percentage that's approximately 72%.
In this way, understanding of probability and how to calculate it properly can help in accurately determining outcomes in different scenarios.

The probability of the sum not being 4 is (36 - 3) / 36, and the probability of the sum being greater than 5 is 21 / 36.
Explanation:When two six-sided dice are rolled, there are 36 possible outcomes. To find the probability that the sum is not 4, we need to calculate the number of outcomes where the sum is not 4 and divide it by the total number of outcomes.
There are 3 outcomes with a sum of 4, so the probability is (36 - 3) / 36.
To find the probability that the sum is greater than 5, we need to calculate the number of outcomes where the sum is greater than 5 and divide it by the total number of outcomes.
There are 21 outcomes with a sum greater than 5, so the probability is 21 / 36.

Answer:
the mean absolute deviation of the data set is 2.
Step-by-step explanation:
To calculate the mean absolute deviation of a data set, we need to follow the following steps:
Step 1: Calculate the mean.
Step 2: Calculate how far away each data point is from the mean (always keeping a possitive distance).
Step 3: Calculate the mean of the deviations.
Step 1: The mean of the data set is:
Mean = (12 + 10 + 10 + 8 + 6+ 7 + 7 + 12)/8 = 72/8 = 9
Step 2:
{12 -9, 10-9, 10-9, 9-8, 9-6, 9-7, 9-7, 12-9} = {3, 1, 1, 1, 3, 2, 2, 3}
Step 3: (3 + 1 + 1 + 1 + 3 + 2 + 2 + 3)/8 = 2
In conclusion, the mean absolute deviation of the data set is 2. Which corresponds to the option B.

Step-by-step explanation:
Definition: The circumcenter is the center of the triangle's circumcircle - the circle that passes through all three of the triangle's vertices. If point H is the circumcenter of the triangle DEF, then the circumcircle passes through its vertices D, E and F (option A is true).
Option B is false, the circumcircle doesn't pass through the points L, M and N. This option is true for inscribed circle, not for circumcircle.
Option C is true, because HD and HE are the radii of the circumcircle.
Option D is false. This option is true for inscribed circle, not for circumcircle.
Option E is false. This option is true for inscribed circle, not for circumcircle.
Option F is true, because both these angles are right angles.

I believe the answer is 70 degrees. If you divide 360 by 9 (amount of degrees divided by amount of sides) you get 40 and we know that the three angles in a triangle add up to 180 degrees. So if we subtract the 40 we got for the top angle we get 140 degrees. We know the other two angles in the triangle are congruent so we can divide 140 by 2 to get the degree of both angles which is 70. Hope this helps!

Jeremy, Sue, and Holly are siblings. Sue was born three years before Holly, and Jeremy was born five years before Sue. The product of Sue's age and Jeremy's age is at most 150.
If x represents the age of Holly, which inequality can be used to find the age of each sibling?
A.
x2 - 11x + 24 ≤ 150
B.
x2 + 8x + 15 ≤ 150
C.
x2 + 8x ≤ 150
D.
x2 + 11x + 24 ≤ 150
Answer:
D is the correct answer
Step-by-step explanation:
Let the age of Holly is x years. Now from the statements of the question we will form the equations.
Sue was born three years before Holly.
Sue = Holly + 3 = x + 3------(1)
Jeremy = Sue + 5
From equation (1)
Jeremy = (x + 3) + 5 = x + 8------(2)
Now statement says the product of Sue's age and Jeremy's age is at most 150.
Sue × Jeremy ≤ 150
(x + 3)(x + 8) ≤ 150
x² + 11x + 24 ≤ 150
Therefore inequality x² + 11x + 24 ≤ 150 can be used to find the age of each sibling.

The equation y = 4x + 4 describes the relationship between the quantities x and y. Are the quantities in a proportional relationship?
Answer:
Yes, because as x grows larger so does y, that means to be in a proportional relationship.
Step-by-step explanation:
Answer: For this to be a proportional relationship, the function would have to be y=4x. Since y=mx+b, this is not a proportional relationship because each time the value of x increases, the value for figure 0 is added on.
So, no. This is not proportional.

Solve 2x2 + 5x = 12.
A. x= three over two and x = −4
B. x = 2 and x = −3
C. x = −6 and x = 5
D. x = one over two and x = one over three
Answer:
A. x= three over two and x = −4
Step-by-step explanation:
2x^2 + 5x = 12
I will use complete the square
Divide each side by 2
2x^2 /2 + 5/2 x = 12/2
x^2 +5/2 x =6
Take 5/2 , divide by 2 and then square it
5/2 ÷2 = 5/2 (5/4) ^2 = 25/16
Add this to both sides
x^2 + 5/2 x + 25/16 = 6 + 25/16
(x+5/4)^2 = 6 *16/16 + 25/16
(x+5/4)^2 = 96/16 +25/16
(x+5/4)^2 = 121/16
Take the square root of each side
sqrt((x+5/4)^2) = sqrt(121/16)
x+5/4 = ±11/4
Subtract 5/4 from each side
x+5/4-5/4 = ±11/4 -5/4
x = ±11/4 -5/4
x = -11/4 - 5/4 and x = 11/4 - 5/4
x = -16/4 = -4 and x = 6/4 = 3/2

Compute the following linear combination.
(79.4, 58.1) + 3(-0.8, 6.3)
Answer:
(77, 77)
Step-by-step explanation:
Carry out the indicated multiplication:
3(-0.8, 6.3) → (-2.4, 18.9)
Next, combine like terms:
(79.4, 58.1) + (-2.4, 18.9). In other words, combine the x terms 79.4 and -2.4 separately and then the y terms 58.1 and 18.9 separately:
(79.4, 58.1) + (-2.4, 18.9) → (77, 77)
The resultant of the following linear combination is:
(77,77)
Step-by-step explanation:We are asked to find the linear combination of the expression:
(79.4, 58.1) + 3(-0.8, 6.3)
We multiply each of the term in the second coordinate by 3 .
i.e. this could also be given by:
(79.4, 58.1) + (3×-0.8, 3×6.3)
= (79.4, 58.1) + (-2.4, 18.9)
Now as there is a addition sign in between the two coordinates i.e. each of the first and the second coordinate will get added
i.e.
= (79.4+(-2.4),58.1+18.9)
= (79.4-2.4,58.1+18.9)
= (77,77)
i.e.
(79.4, 58.1) + 3(-0.8, 6.3)=(77,77)
PLEASE HELP : Which line could be the graph of the points in the table?
Answer:
see below
Step-by-step explanation:
As x gets larger, y gets smaller. Only one of the graphs has that characteristic.
Line of the graph (3) could be the graph of the points in the table.
To determine which line could be the graph of the points in the table, we can plot the points and then draw a line that passes through all three points.
The line that passes through all three points is the line that intersects the y-axis at 0 and has a slope of −2.
Therefore, the line that could be the graph of the points in the table is:
y = -2x
We can check our answer by substituting the points from the table into the equation. If the points satisfy the equation, then the equation is a possible graph of the points.

A farmer is searching his farmland, looking for a missing horse that went grazing in the field of newly cut hay. He finds himself on the opposite corner of where he started and wants to return to his truck as soon as possible. The field is 450 yd by 600 yd. How far will he walk if he walks diagonally across the field, and how much distance will he save instead of walking around the field? Explain your answer. Make sure to use the Pythagorean Theorem when solving this word problem.
Answer:
750 yards
Step-by-step explanation:
I entered the area of the field into a Pythagorean Theorem Calculator and it concluded that the diagonal length of the field would be approximately 750 yard.
Answer:
300 yd saved
Step-by-step explanation:
The length of the diagonal of the field is found using the Pythagorean Theorem and is
d = √( 450 yd)² + ( 600 yd)² ) = √562500 yd² = 750 yd is the diagonal distance. If, on the other hand, the farmer walks the length and width of the perimeter of the field, that would be 450 yd + 600 yd, or 1050 yd.
The farmer could spare himself 1050 - 750, or 300 yd, of walking if he crosses the field along a diagonal.
