Answer: Second option is correct.

Step-by-step explanation:

Since we have given that

$p(x)=(x-1)(x-2)(x+5)\\\\p(x)=x^3+2x^2-13x+10$

So, we can see that

The graph is first increasing and then decreasing to the right.

And it is cubic polynomial.

the graph reaches its maximum at (-2.8,40.14) and then its minimum at (1.5,-1.6)

Hence, Second option is correct.

Consider the quadratic function f(x)= 9x^2+30x+25=0

Alchen [17]

Answer:

D) 0

There is 1 real solution.

Step-by-step explanation:

Hi there!

$f(x)= 9x^2+30x+25=0$

This is written in standard form:

$f(x)=ax^2+bx+c$

This means:

a=9

b=30

c=25

The discriminant states:

$D=b^2-4ac$

If D>0, there are 2 real solutions.

If D=0, there is 1 real solution.

If D<0, there are 2 complex solutions.

Plug in the values:

$D=30^2-4(9)(25)\\D=0$

Therefore, there is 1 real solution.

I hope this helps!

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.

The function shown in the graph is

pshichka [43]

Answer:

Linear function

y = 2x - 1

Step-by-step explanation:

This is a linear function because the line is straight, having no curved.

The equation for a linear graph is y=mx + b.

x and y represent points on he graph.

"m" represents the slope of the graph. Reading from left to right, if a positive slope, then the graph continues upward. If negative, then it's a graph down downwards.

"b" represents the y-intercept, when the graph hits the y-axis. It's also the initial value.

In the photo, we can see the y-intercept is (0, -1).

Slope is calculated by rise over run. Choose two random points on the graph. Count the "rise", or how many vertical units are between the points. If the point on the right is lower than the point on the left, the rise is negative. Count the "run", which is the number of horizontal units between the points.

For the point (0, -1) and (3, 5).

m = rise/run

m = 6/3

m = 2

Substitute m=2 and b= -1 into the equation of a line.

y = 2x - 1
