Answer:

Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.

In one U.S.​ city, the quadratic function f (x )equals 0.0039 x squared minus 0.42 x plus 36.79 models the​ median, or​ average,
Leviafan [203]

Answer:

The average age was minimum at 1954 and the average age is 25.5.

Step-by-step explanation:

The given quadratic function is

f(x)=0.0039x^2-0.42x+36.79

It models the​ median, or​ average, age,​ y, at which men were first married x years after 1900.

In the above equation leading coefficient is positive, so it is an upward parabola and vertex of an upward parabola, is point of minima.

We need to find the year in which the average age was at a minimum​.

If a quadratic polynomial is f(x)=ax^2+bx+c, then vertex is

Vertex=(-\dfrac{b}{2a},f(-\dfrac{b}{2a}))

-\dfrac{b}{2a}=-\dfrac{(-0.42)}{2(0.0039)}=53.846153\approx 54

54 years after 1900 is

1900+54=1954

Substitute x=54 in the given function.

f(54)=0.0039(54)^2-0.42(54)+36.79=25.4824\approx 25.5

Therefore, the average age was minimum at 1954 and the average age is 25.5.

Big Enos loves Coors beer but he lives in Georgia and nobody sells Coors east of Texas. So he offers to pay Cletus "The Snowman"
Alik [6]

Answer:

Snowman Expenses:

a) Income Tax deductible expenses:

Payment for 400 cases of beer = $10,000

Payment for fuel = $650

Total = $10,650

b) The expenses above are allowable because they are "ordinary and necessary expenses incurred in carrying on any trade or business."  IRS Code 162.

c) The bribe paid to the Sheriff of $1,000 is not allowable under the same code.

d)  Such payments are not allowable because, according to IRS Code 162  section C: 1 and 2, they are described as "Illegal bribes, kickbacks, and other payments" and "other illegal payments."

Step-by-step explanation:

a) According to the Internal Revenue Code 162 which details trade or business expenses, section A specifically state that "There shall be allowed as a deduction all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business, including—

(1)a reasonable allowance for salaries or other compensation for personal services actually rendered;

(2)traveling expenses (including amounts expended for meals and lodging other than amounts which are lavish or extravagant under the circumstances) while away from home in the pursuit of a trade or business; and ..."

b) Bribes are illegal payments prohibited by states law.  Snowman paid the payment in order not to get his vehicle impounded and himself imprisoned, according to the Sheriff's threats.  That he was over-speeding in order to meet his business appointment does not guarantee him the right to bribe a government official.
