Which statement accurately describes the difference between short-term and long-term capital gains in terms of taxes? A. Long-term capital gains are from investments that have been held for more than one year and are taxed at a lower rate than short-term capital gains. B. Long-term capital gains are from investments that have been held for at least six months and are taxed at a lower rate than short-term capital gains. C. Long-term capital gains are from investments that have been held for more than one year and are taxed at a higher rate than short-term capital gains. D. Long-term capital gains are from investments that have been held for at least six months and are taxed at a higher rate than short-term capital gains.
Answer: A. Long-term capital gains are from investments that have been held for more than one year and are taxed at a lower rate than short-term capital gains.
Step-by-step explanation:
Long-term capital gains are indeed from investments that have been held for more than a year as opposed to short term gains from investments of less than a year. This means that long term gains can come from investments such as stocks and bonds.
Long-term capital gains are taxed at a lower rate than short term gains with most long term gains being taxed at 15% or lower. This is in contrast to short-term gains that are taxed at the same rate as ordinary income which means it could go up to as high as 37%.

guys please help me i cant solve this logarithmic equation
Answer:
Step-by-step explanation:
I'll just write log for log base 10. The important rules about logarithms we need to know are:
[tex] a \log b = \log( b^a) [/tex]
[tex] \log a + \log b = \log( ab) [/tex]
and at the end we'll need something like
[tex]\log a = \log b \implies a=b[/tex]
Suitably armed we can begin,
[tex] \left( 1 + \dfrac{1}{2x} \right) \log 3 + \log 2 = \log (27 - 3^{1/x}) [/tex]
First rule,
[tex] \log 3^{ 1 + 1/2x} + \log 2 = \log (27 - 3^{1/x}) [/tex]
Second rule,
[tex] \log 2(3^{ 1 + 1/2x}) = \log (27 - 3^{1/x}) [/tex]
Third rule,
[tex] 2(3^{ 1 + 1/2x}) = 27 - 3^{1/x} [/tex]
We can rewrite this to be a quadratic equation in [tex]y=3^{1/2x}[/tex].
[tex] 6 (3^{1/2x}) = 27 - (3^{1/2x})^2 [/tex]
[tex]y^2 +6y - 27 =0[/tex]
[tex](y - 3)(y+9)=0[/tex]
[tex]y=3 \textrm{ or } y=-9[/tex]
First solution:
[tex]3^{1/2x} = 3 = 3^{1}[/tex]
[tex]1/2x = 1[/tex]
[tex]1=2x[/tex]
[tex]x = 1/2[/tex]
Second solution,
[tex]3^{1/2x} = -9[/tex]
No real powers of 3 will be negative, no solution here.
Answer: x=1/2
Check:
1 + 1/2x = 2 so the left side is log 2(3²) = log 18
Right side, log(27-3^2) = log 18 √

The sum of two numbers is 44. The smaller number is 14 less than the larger number. What are the numbers?
Larger Number:
Smaller Number:
Answer:
Smaller number = 15
Larger number = 29
Step-by-step explanation:
Let smaller number be S
Let larger number be L
Given :
Sum = 44. That is , S + L = 44
Smaller number is 14 less than larger number. That is , S = L - 14
Therefore the equations are :
S + L = 44 ------(1)
S = L - 14 ------(2)
Substitute (2) in ( 1 )
(L - 14 ) + L = 44
L - 14 + L = 44
2 L = 44 + 14
2 L = 58
L = 29
Substitute L in (1) : S = L - 14 = 29 - 14 = 15
Answer:
Larger Number: 29
Smaller Number: 15
Step-by-step explanation:
By assigning the letters "L" and "S", to the larger number and smaller number respectively, we can solve this using simultaneous equations:
L+S = 44
L-14 = S
By substituting S = L-14 into the first equation, we get:
L+L-14 = 44 (add 14 to both sides)
L+L = 58 ( divide by 2 as L+L becomes 2L)
L=29
When L= 29, S= 29-14 which is 15

The equation of a circle is (x+8)2+(y-5)2=14. What are the coordinates of the center of the circle?
Answer:
(-8,5)
Step-by-step explanation:
The standard form of the equation of a circle is expressed as;
(x-a)^2+(y-b)^2 = r^2 where;
(a, b) is the centre
r is the radius
Given the equation (x+8)^2+(y-5)^2=14.
Compare the two expressions
-a = +8
a = -8
Similarly;
-b = -5
b = 5
Hence the centre of the circle is at (-8,5)

The radius of a circle is 2 meters. What is the area of a sector bounded by a 135 degree arc? Give the exact answer in simplest form
Answer:
Area of circle bounded by a 135 ° arc is 4.71 m ²
Step-by-step explanation:
Given that :-Radius of circle, r = 2 m
Angle of the circle , θ = 135 °
To Find :-Area of circle bounded by a 135 ° arc.
Solution :-Using Formula
Area of circle = θ/ 360 × π × r ²
substitute the values,
Area of circle = 135 /360 × 3.14 × ( 2 m) ²
solve it
Area = 27 / 72 × 3.14 × 4 m ²
Area = 27 / 18 × 3.14
Area = 1.5 × 3.14
Area = 4.71 m ²
Therefore, Area of circle bounded by a 135 ° arc is 4.71 m ²

Two lines are intersecting. What is the value of X? And to your answer in the box
Answer:
x = 51
Step-by-step explanation:
The two angles form a straight line
Angles that form a straight line add up to equal 180
Hence, 2x + 4 + x + 23 = 180
( note that we just created an equation that we can use to solve for x )
we now solve for x using the equation we created
2x + 4 + x + 23 = 180
step 1 combine like terms
2x + x = 3x
4 + 23 = 27
we now have 180 = 27 + 3x
step 2 subtract 27 from each side
180 - 27 = 153
27 - 27 cancels out
we now have 153 = 3x
step 3 divide each side by 3
153 / 3 = 51
3x / 3 = x
we're left with x = 51

Hope it is helpful...The perimeter of a rectangle is 84 cm. If the length is 29 cm write an equation you can use to answer this question
Answer:
The perimeter of a rectangle has the general formula P=2L+2W. Since you know P and L, you can plug those values into the formula and solve for W.
Hope this answer is right!!
Answer:
Width: 13
Area: 42
Step-by-step explanation:
A rectangle has equal opposite sides, so if you know one side, you know that the opposite side will be the same. Then you can subtract it from the perimeter, and divide the remaining number in half because it represents the other opposite sides. If you were trying to find the area, do that to find the length and width. 29x13=42, so the area is 42. If you were trying to find the width, that would be 13 because
29+29=58
84-58=26
And 26/2=13
Zikri wins a cash prize of one million ringgit. She invests the money into an investment institution that offer
a return of 6% per year. The total amount of Zikris investment after n years is calculated by using the formula
J = P(1 + k)" with p is the initial investment and k is the rate of return per year. Find Zikris total investment
after 15 years.
Answer: 2,396,558 Ringgit
Step-by-step explanation:
J = P * ( 1 + k)^n
P = initial investment of 1,000,000 Ringgit
k = rate of return of 6% per annum
n = Number of years of investment
J = 1,000,000 * ( 1 + 6%)¹⁵
= 1,000,000 * 2.396558193
= 2,396,558 Ringgit
