A portfolio is efficient if which of the following is true?
Answers
Answer:
In economics, a portfolio is a term for a specific set of stocks, bonds, shares, and other securities owned by an investor. In general, the investor seeks to compile and diversify a portfolio of securities that offers maximum profitability and at the same time is diverse, in order to minimize possible risks. In general, these types of portfolios are considered efficient, as they do not leave the investment risk tied to a single factor. However, these two goals often go against each other, so the composition of the portfolio means a certain compromise.

The option that best describes the elevation of Desert Shores is; A. Desert Shores is lower than 55 meters below sea level.
What is the Elevation below sea level?We are told that the elevation of Desert Shores, California, is less than -55 meters.
Now, an elevation of a natural landmass like this is usually given with reference to the sea level. If above sea level, it is positive but if below sea level, it is negative.
Now, the elevation is negative as we can see that it is given as -55 meters. Thus, we can easily conclude that Desert Shores is lower than 55 meters below sea level.

a box of rotini noodles contains 10 servings. If you eat 7/8 of the recommended serving as a meal, how many complete meals can you get from one box
Answers
Answer:
11 whole meals
Step-by-step explanation:
Lets say that you have 800 noodles in one box. The serving size would be 80 noodles / meal. Then the question says you eat 7/8 of the recommended meal, which would be 70 noodles. When you divide 800 by 70, you get 11.4285714286 meals. Remember that the question is asking for full meals, so you round down to 11 full meals.
If you want a more algebraic answer:
10 servings (\(\frac{7/8}{1}\)) = 10 (8 / 7) = 80/7 = 11.4285714286 meals.
round down to 11 full meals.
11 complete meals can you get from one box.
Given that, a box of rotini noodles contains 10 servings.
If you eat 7/8 of the recommended serving as a meal, we need to find how many complete meals can you get from one box.
What are fractions?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, whereas the whole can be any number, a specific value, or a thing.
Now, the number of complete meals=10÷7/8
=80/7
=11.42≈11
Therefore, 11 complete meals can you get from one box.

The ratio of the interior angles of a triangle is 3: 3:4. What are the angle
measures
Answers
Answer:
3X=54°
3X=54°
4X=72°
Step-by-step explanation:
3X+3X+4X=180°(SUM OF INTERIOR ANGLES OF A TRIANGLE ADOPTS TO 180°)
10X=180°
X=18°
THERFORE;
3X=18 * 3 = 54°
4X=18 * 4 = 72°
The sum of all the interior angles of a triangle is 180°. The measure of the angles are 54°, 54° and 72°.
What is a Triangle ?A triangle is geometric figure bounded by three straight lines.
The sum of all the interior angles of a triangle is 180°.
In a triangle, the length of the longest side is always less than the sum of the length of the other two sides.
In the given figure, the angles of a triangle are 3x, 3x and 4x.
Since the sum of interior angles is 180°,
3x + 3x + 4x = 180
x = 18
Thus the angles can be obtained by substituting the value of x as follows,
3x = 3 × 18 = 54°
3x = 3 × 18 = 54°
And, 4x = 4 × 18 = 72°.
Hence, the angles of the given triangle are 54°, 54° and 72°.

The output value of (g/f)(x) is 9x/(7x + 28).
The domain of g/f is (-∞, -4) U (-4, ∞)..
How to determine the corresponding composite function?In this exercise, we would determine the corresponding composite function of f(x) and g(x) under the given mathematical operations in simplified form as follows;
(g/f)(x) = (9/(x + 4)) ÷ 7/x
By rearranging the mathematical expression using the multiplication operation, we have the following:
(g/f)(x) = (9/(x + 4)) × x/7
(g/f)(x) = 9x/(7x + 28)
For the restrictions on the domain, we would have to equate the denominator of the rational function to zero and then evaluate as follows;
7x + 28 ≠ 0
7x ≠ -28
x ≠ -4

If the equation is cos x = x^3, the interval of length 0.01 that contains a root is [0.86, 0.87]
The given equation is
cos x = x^3

cos x - x^3 = 0
Therefore the equation will be
f(x) = cos x - x^3
Here to find the interval of length 0.01 that contains a root, we have to use the intermediate value theorem

If trapezoid JKLM is translated using the rule (x, y) → (x + 3, y − 3) and then translated using the rule (x, y) → (x − 1, y + 1) to create trapezoid J″K″L″M″, what is the location of L″?
Answers
The location of L″ is (-5, 0).
To find the location of L″, we first need to apply the first translation rule to the coordinates of trapezoid JKLM:
J': (x, y) → (x + 3, y - 3) => J'(-2+3, 1-3) = J(1, -2)
K': (x, y) → (x + 3, y - 3) => K'(1+3, 1-3) = K(4, -2)
L': (x, y) → (x + 3, y - 3) => L'(3+3, -2-3) = L(6, -5)
M': (x, y) → (x + 3, y - 3) => M'(-4+3, 2-3) = M(-1, -1)
Now, we need to apply the second translation rule to the coordinates of J', K', L', and M':
J'': (x, y) → (x - 1, y + 1) => J''(1-1, -2+1) = J''(0, -1)
K'': (x, y) → (x - 1, y + 1) => K''(4-1, -2+1) = K''(3, -1)
L'': (x, y) → (x - 1, y + 1) => L''(6-1, -5+1) = L''(5, -4)
M'': (x, y) → (x - 1, y + 1) => M''(-1-1, -1+1) = M''(-2, 0)
Therefore, the location of L″ is (-5, 0).

Answer:

Step-by-step explanation:
You want the angle opposite the side of length 7 in the triangle with other sides of lengths 4 and 8.
Law of CosinesThe law of cosines relates the angles of a triangle to the side lengths. For triangle ABC with opposite sides a, b, c, the relation is ...
c² = a² +b² -2ab·cos(C)
ApplicationSolving for angle C, we have ...
cos(C) = (a² +b² -c²)/(2ab)
C = arccos((a² +b² -c²)/(2ab))
In this triangle, that means ...
C = arccos((4² +8² -7²)/(2·4·8)) = arccos(31/64)
C ≈ 61.03°
The angle of interest is about 61.03°.

Question 9(Multiple Choice Worth 5 points) (06.01 MC) Solve the system of equations below. x + y = 8 3x + 2y = 21 (3, 5) (5, 3) (2, 6) (6, 2)
Answers
How to get this answer:
x+y = 8 solves to y = -x+8 after isolating y. You subtract x from both sides.
Plug this into the second equation and solve for x
3x + 2y = 21
3x + 2( y ) = 21
3x + 2( -x+8 ) = 21 ... replace y with -x+8
3x - 2x + 16 = 21
x + 16 = 21
x = 21-16
x = 5
Use this to find y
y = -x+8
y = -5+8
y = 3
We have x = 5 and y = 3 pair up to get the ordered pair solution (5,3)

The starting balance is $625.91 if the card has a billing cycle of 30 days and an APR of 14.75%. Option (C) is correct.
What is APR?The full name of APR is the annual percentage rate. It is defined as the percentage rate applied on the borrowing money in the form of interest, but APR has applied annually.
We have:
His card has a billing cycle of 30 days and an APR of 14.75%.
Here the list data is not mentioned, clearly. Transactions with the amount.
As we know, the APR is the annual percentage rate, which is 14.75%.
Monthly percentage rate = 14.75/12 = 1.22%
But we can calculate the new balance with the formula:
Previous Balance + Finance Charge + New Purchases - (Payments + Credits) = New Balance
Thus, the starting balance is $625.91 if the card has a billing cycle of 30 days and an APR of 14.75%. Option (C) is correct.

sin α = 4/5
tan β = 12/5
From trigonometric ratios, we can say that;
cos α = 3/5
sin β = 12/13
cos β = 5/13
We know from trigonometric identities that cos (a + b) = cos a cos b - sin a sin b.
Thus;
cos(2α + β) = cos 2α cos β - sin 2α sin β
