Answer: 0.25 or 25%
Explanation:
1) The first stock will double its value ⇒ new value = $1,000 × 2 = $2000
2) The second stock wil dropt to half ⇒ new value = $ 1,000 / 2 = $500
3) Total value of the investments after the change of the values: $2,500 + $ 500 = $ 2,500.
4) Return on investment = benefit / investment
5) benefit = new value - investment = $2,500 - $2000 = $ 500
6) Return on investment = $500 / $2,000 = 0.25
Which you can also represent in percent form: 0.25 = 25%.

Show that the point (7/25, 24/25) is on the unit circle
To show that the point (7/25, 24/25) is on the unit circle, we need to demonstrate that its distance from the origin is equal to 1.
Explanation:To show that the point (7/25, 24/25) is on the unit circle, we need to demonstrate that its distance from the origin is equal to 1.
The distance between two points, (x1, y1) and (x2, y2), is given by the formula: √((x2-x1)² + (y2-y1)²).
In this case, the distance between the point (7/25, 24/25) and the origin (0, 0) can be calculated as: √((7/25-0)² + (24/25-0)²) = √((49/625) + (576/625)) = √(625/625) = 1.
Since the distance between the given point and the origin is indeed equal to 1, we can conclude that the point is on the unit circle.

Answer:
Step-by-step explanation:
The given sequence is:
1,6,11,16,...
Since, the sequence is Arithmetic progression, therefore
The general term for the sequence is:
[tex]A_{n}=a+(n-1)d[/tex]
where a is the first term of the sequence and d is common difference.
Substituting the given values, we get

Which function has the greatest y-intercept? (2 points)
f(x)
g(x)
h(x)
All three functions have the same y-intercept.
The function h(x) has the greatest y-intercept of 8, as it crosses the y-axis at the highest point.
Explanation:The function that has the greatest y-intercept is the one that crosses the y-axis at the highest value. The y-intercept is the point where the graph of a function intersects the y-axis, which is when x = 0. So, to find the function with the greatest y-intercept, we need to evaluate the y-value when x = 0 for each function.
Let's consider the functions f(x), g(x), and h(x). If f(x) has an equation of y = 3x + 5, g(x) has an equation of y = x - 2, and h(x) has an equation of y = -2x + 8, we can plug in x = 0 and see which function gives us the greatest y-value.
For f(x), when x = 0, y = 3(0) + 5 = 5. For g(x), when x = 0, y = 0 - 2 = -2. And for h(x), when x = 0, y = -2(0) + 8 = 8. Thus, h(x) has the greatest y-intercept because it crosses the y-axis at the highest point, which is 8.

7 / 35 = ? / 28
To find the missing number in the proportion 7 / 35 = ? / 28, we can use the concept of cross-multiplication. The missing number is 5.6.
Explanation:To find the missing number in the proportion 7 / 35 = ? / 28, we can use the concept of cross-multiplication. Cross-multiplication involves multiplying the numerator of one fraction by the denominator of the other fraction, and then setting the two products equal to each other. In this case, we have 7 * 28 = ? * 35. Solving for the missing number, we get:
So, the missing number is 5.6.

cell phone company A charges $20 per month plus $0.05 per text message. Cell phone company B charges $10 per month plus $0.07 per text message. Is there any number of text messages that will result in the exact same charge from both companies?
Answer : The number of text messages that will result in the exact same charge from both companies is, 500
Step-by-step explanation :
Let the number of text messages be, 'x'
Cell phone company A charges $20 per month plus $0.05 per text message. Thus, the equation will be:
[tex]20+0.05x=0[/tex] ............(1)
Cell phone company B charges $10 per month plus $0.07 per text message. Thus, the equation will be:
[tex]10+0.07x=0[/tex] ............(2)
Now equating equation 1 and 2, we get:
[tex]20+0.05x=10+0.07x[/tex]
[tex]20-10=0.07x-0.05x[/tex]
[tex]10=0.02x[/tex]
[tex]x=\frac{10}{0.02}[/tex]
[tex]x=500[/tex]
Thus, the number of text messages that will result in the exact same charge from both companies is, 500
find the zero of the function. state the multiple zero . y=9x^3 -9x
The zeros of the function y = 9x³ - 9x are x = 0, x = 1, and x = -1. There are no multiple zeros for this function.
The question seeks to identify the zeros of the function y = 9x^3 - 9x. To find the zeros, we set the function equal to zero and solve for x.
Step 1: Set the function equal to 0: 0 = 9x³ - 9x.Step 2: Factor out a common term: 0 = 9x(x² - 1).Step 3: Factor further using difference of squares: 0 = 9x(x - 1)(x + 1).Step 4: Set each factor equal to zero: x = 0, x = 1, x = -1.Step 5: Identify the multiple zero, if any. In this case, there are no multiple zeros.The zeros of the function are x = 0, x = 1, and x = -1.
Therefore, as per the above explaination, the correct answer is x = 0, x = 1, and x = -1.

If 3x-1=11, then 2x=?
To find 2x, we first need to solve for x in the equation 3x - 1 = 11. We isolate x by adding 1 to both sides and divide by 3 to obtain x = 4. Finally, multiplying x by 2 gives us 2x = 8.
Explanation:To solve the equation 3x - 1 = 11 for 2x, we need to isolate x first. Adding 1 to both sides, we get 3x = 12. Dividing both sides by 3, we find that x = 4. Now, to find 2x, we simply multiply x by 2, which gives us 2(4) = 8.

3. Brinn’s rectangular kitchen has an area of 81 square feet. The kitchen is 9 times as many square feet as Brinn’s pantry. If the rectangular pantry is 3 feet wide, what is the length of the pantry?
The length of the pantry is 3 feet.
To find the length of the pantry, we need to determine its area first. According to the question, the kitchen is 9 times the size of the pantry. With the kitchen's area being 81 square feet, the pantry's area would be 81 square feet divided by 9, which equals 9 square feet. Since we are given that the width of the pantry is 3 feet, we divide the total area of the pantry by its width to find the length.
The calculation is as follows:
Area of kitchen: 81 sq ft
Area of pantry: 81 sq ft / 9 = 9 sq ft
Width of pantry: 3 ft
Length of pantry: Area of pantry / Width of pantry = 9 sq ft / 3 ft = 3 feet long.
Find the area of a regular hexagon with the given measurement.
2 sqrt3 apothem
A =
...?
Answer:
41.57 unit²
Step-by-step explanation:
We know,
Area of a regular hexagon = [tex]3\times (sidelength)\times (apothem)[/tex].
The length of the apothem = [tex]2\sqrt{3}[/tex] units.
Since, we know, 'a regular hexagon splits into 6 identical equilateral triangles'.
As, the apothem of the regular hexagon = height of the equilateral triangle
So, height of the equilateral triangle = [tex]2\sqrt{3}[/tex] units.
As, in the equilateral triangle, 'One of the side length is the S, other will be [tex]\frac{S}{2}[/tex] and height is [tex]2\sqrt{3}[/tex] units'.
So, using Pythagoras Theorem, we have,
[tex]hypotenuse^{2}=perpendicular^{2}+base^{2}[/tex]
i.e. [tex]S^{2}=(\frac{S}{2})^{2}+(2\sqrt{3})^{2}[/tex]
i.e. [tex]S^{2}=\frac{S^2}{4}+12[/tex]
i.e. [tex]S^{2}-\frac{S^2}{4}=12[/tex]
i.e. [tex]\frac{3S^2}{4}=12[/tex]
i.e. [tex3S^2=48[/tex]
i.e. [texS^2=16[/tex]
i.e. S= 4 units
That is, the side length of the hexagon = 4 units.
Thus, the area of the hexagon is given by,
Area of a regular hexagon = [tex]3\times (4)\times (2sqrt{3})[/tex]
i.e. Area of a regular hexagon = [tex]12\times (2sqrt{3})[/tex]
i.e. Area of a regular hexagon = [tex]24sqrt{3}[/tex]
i.e. Area of a regular hexagon = 41.57 unit²
Hence, the area of the regular hexagon is 41.57 unit².

A triangle has side length of 14 cm 48 cm and 50 cm classify it as acute obtuse or right
The triangle with side lengths of 14 cm, 48 cm, and 50 cm is a right triangle.
Explanation:The lengths of the sides of the triangle are 14 cm, 48 cm, and 50 cm. To classify the triangle, we need to determine if it is acute, obtuse, or right.
Using the Pythagorean theorem, we can check if it satisfies the condition for a right triangle. If the square of the length of the longest side (50 cm) is equal to the sum of the squares of the other two sides (14 cm and 48 cm), then it is a right triangle.
In this case, (50)^2 = (14)^2 + (48)^2, which is true. Therefore, the triangle is a right triangle.
Final answer:
A triangle with side lengths of 14 cm, 48 cm, and 50 cm is classified as an acute triangle.
Explanation:
A triangle with side lengths of 14 cm, 48 cm, and 50 cm can be classified as an acute triangle.
To determine this, we need to check if the square of the longest side (50 cm) is less than the sum of the squares of the other two sides (14 cm and 48 cm).
502 < 142 + 482
2500 < 196 + 2304
2500 < 2500
This inequality is not true, so the triangle is not obtuse or right. Thus, it is classified as an acute triangle.
