According to the income section shown below from the 1040EZ form,
which of the following on line 2 would make the taxpayer ineligible to use this form?
A P E X ANSWER PLEASE I NEED ANSWER ASAP PLEASE AND THANK YOU!
Answer:
A) interest in the amount of $1,600
Sorry, this is late!
Step-by-step explanation:
Line 2 states that a taxpayer is ineligible to use the form if their total taxable interest is over $1,500. Answer A implies that the interest rate is $1,600 which applies perfectly.
The thing on line 2 that would make the taxpayer ineligible to use this form is D, None of the above.
What is a 1040EZ form?This refers to the tax form in the United States that is used for people below the age of 65 and have dependents that earn less than $100,000 yearly.
Hence, we can see from line 2, we can see that it is stated that taxable interest is more than $1,500 and the person becomes ineligible and none of the answer choices satisfies this, so option D is the answer.

the 42 haircuts given on Friday were $588. How
many adults and children had haircuts on Friday? The
answer is the solution to the following system.
4c + 14a = 588
c+a=42
Answer:
Step-by-step explanatio
it can be 7 children and 1 adult, or 3 adults.
i'd say it's, c = 28, while a = 14
There are 40 adults and 2 children had haircuts on Friday.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We are given the system of equation as;
x + y = 42
4x + 14y = 568
We need to solve, let 'x' = 42-y and substitute this expression for 'x' in the second equation to get:
4(42-y) + 14y = 568
168 - 4y + 14y = 568
168 + 10y = 568
10y = 400
y = 40
therefore, x = 2
There are 40 adults and 2 children had haircuts on Friday.

What is the equation of the sinusoid shown in the graph?
A. y=3cos(pi/2x)
B. y=3cos(4x)
C. y=cos(4x)
D. y=3cos(1/4x)
Answer:
Answer: C
Step-by-step explanation:
The Cosine Function
The graph of a cosine function is a sinusoid that starts at its maximum value of 1 at x=0 and takes x=2π radians to complete a full cycle. The function of the parent cosine function is:
[tex]y=\cos x[/tex]
Both the amplitude A and the angular frequency w of a cosine can be modeled by the function
[tex]y=A\cos(\omega x)[/tex]
The graph of the cosine function shown in the figure has an amplitude of A=3 and it completes a full cycle at x=π/2, thus:
[tex]\frac{\pi}{2}\omega =2\pi[/tex]
Thus:
[tex]\omega = 4[/tex]
Therefore, the equation of the sinusoid is:
[tex]y=3\cos (4x)[/tex]
