Answer:
If you're simplifying it then it should be -5*x^4-6*y^3.
B. h(x) + 41 = 31x2 + 77x
C. y = 31x2 + 77x − 41
D. y + 41 = 31x2 + 77x
Answer:
I think the answer is A. y= 31x2 + 77x + 41
Step-by-step explanation:
The function h(x) = 31x2 + 77x + 41 can also be written as y = 31x2 + 77x + 41, as y is often used interchangeably with f(x) or h(x) in mathematical functions. The remaining options do not accurately reformulate the original equation.
The function
h(x) = 31x2 + 77x + 41
can also be written as
y = 31x2 + 77x + 41
. This is because in mathematical functions, y is often used interchangeably with f(x) or h(x), representing the output or dependent variable. It's important to note that, the other options do not correctly represent the original equation. In Option B, the constant term is incorrectly added to the function on the left side; in Option C, the constant term is incorrectly subtracted; and in Option D, the constant term is incorrectly added to 'y' on the left side.

1a) Calculate how much Cindy will have to pay in Social Security tax (6.2%) based on this salary.
1b) Calculate how much Cindy will have to pay in Social Security tax if the tax was increased by 1.89%.
2a) Calculate Cindy’s annual Social Security benefit (about 42%) if her salary remains unchanged until she retires (annual average is $45,000).
2b) Calculate Cindy’s annual Social Security benefit if her salary remains unchanged but benefits (based on her annual salary of $45,000) were cut from 42% to 29%.
3) If Cindy were given a choice between the increase in Social Security tax now or the decrease in Social Security benefits when she retires, which would you recommend she choose? Explain your answer thoroughly.
Answer:
1a) $45,000 * 0.062 = $2,790
1b) 6.2% + 1.89% = 8.09%; $45,000 * 0.0809 = $3640.50
2a) $45,000 * 0.42 = $18,900
2b) 42% - 13% = 29% $45,000 * 0.029 = $13,050
3) You should probably recommend she pay the extra taxes now. If the tax were increased by 1.89%. Cindy would have to pay an extra $3640.50 - $2,790 = $850.50 per year for the 32 years before she retires. This adds up to $27,216 over the length of 32 years. On the other hand, if benefits were decreased from 42% of her salary to 29% of her salary the time of Cindy’s retirement (approximations), she would receive $18,900 - $13,050 = $5,850 less per year after she retires. This adds up to $58,500 in just 10 years.

Answer:
Step-by-step explanation:
Answer:
-x + 23y
Step-by-step explanation:
-2(3x - 4y) + 5(x+3y)
Expand the brackets.
-6x + 8y + 5x + 15y
Rearrange.
- 6x + 5x +8y + 15y
Add or subtract like terms.
- 1x + 23y
Bellies, and the pattern can be modeled by a sine function. He has found
it to have a maximum of 3, minimum of −5, and period of 2π. Which of
the following sine functions could model Micah's stock rating?
Answer:
The required function is f(x)=4sinx-1.
Step-by-step explanation:
The standard sine function is defined as
....(1)
Where a is amplitude, period is , c is phase shift and d is midline.
It is given that the maximum value is 3 and the minimum value is -5. Amplitude is half of difference between minimum and maximum.
The value of a is 4.
The period is 2π.
Midline is average of maximum and minimum.
Substitute a=4, b=1, c=0 and d=1 in equation (1).
Therefore the required function is f(x)=4sinx-1.

Step-by-step explanation:
Each atom of the gas weighs 1.67 ⋅ 10−24 grams. 6.71 grams, because (5.04 + 1.67) ⋅ (1023⋅ 10−24 ) = 6.71. ... 0.67 grams, because (5.04 + 1.67) ⋅ (1023⋅ 10−24 ) = 6.71 ⋅ 10−1.
