Use a direct proof to show that the product of two rational numbers is rational.
We have shown that the product of two rational numbers is rational.
What is Number system?A number system is defined as a system of writing to express numbers.
Let a and b be two rational numbers, such that:
a = p/q
b = r/s
where p, q, r, and s are integers and q, s are non-zero.
We need to show that the product ab is also a rational number.
We have:
ab = (p/q) x (r/s)
= (p x r) / (q x s)
Since p, q, r, and s are all integers,
ab = m/n
where m = p x r and n = q x s.
Since both m and n are integers and n is non-zero ,we can conclude that ab is a rational number.
Therefore, we have shown that the product of two rational numbers is rational.

hail 0.5 inch deep and weighing 1800 pounds covers a roof. the hails weight varies directly with its depth. write an equation that relates d and w. then predict the weight on the room of hail that is 1.75 inches deep
In a directly proportional relationship, increasing one variable will increase another. The weight of the roof whose depth is 1.75 inches is 6,300 pounds.
What is the directly proportional relationship?In a directly proportional relationship, increasing one variable will increase another. This directly proportional relationship between p and q is written as p∝q where that middle sign is the sign of proportionality.
Let there are two variables p and q. Then, p and q are said to be directly proportional to each other if p = kq, where k is some constant number called the constant of proportionality.
Given the hail's weight varies directly with its depth. Therefore, the relation can be written as,
Weight ∝ Depth
W∝D
Introducing the constant to remove the proportionality we will get the equation as,
W = kD
1800pounds = k × 0.5 inches
3600ponds/inches = k
Now, the weight of the roof whose depth is 1.75 inches can be written as,
W = kD
W = 3600 × 1.75
W = 6,300 pounds
Hence, the weight of the roof whose depth is 1.75 inches is 6,300 pounds.

Find a polynomial of degree 3 with real coefficients and zeros of -3,-1, and 4, for which f(-2)=-24
We want to find a polynomial
f(x) = a x³ + b x² + c x + d
such that the roots of f are x = -3, x = -1, and x = 4, and f(x) takes on a value of -24 when x = -2.
The factor theorem for polynomials tells us that we can factorize f(x) as
a x³ + b x² + c x + d = a (x + 3) (x + 1) (x - 4)
Expand the right side:
(x + 3) (x + 1) (x - 4) = x³ - 13x - 12
So we have
a x³ + b x² + c x + d = a x³ - 13a x - 12a
In order for both sides to be equal, the coefficients of both polynomials on terms of the same degree must be equal. This means
a = a (of course)
b = 0 (there is no x² term on the right)
c = -13a
d = -12a
We also have that f (-2) = -24, which means
f (-2) = a (-2 + 3) (-2 + 1) (-2 - 4)
-24 = 6a
a = -4
which in turn tells us that c = 52 and d = 48.
So we found
f(x) = -4x³ + 52x + 48

Answer:
11,260
Step-by-step explanation:
im pretty sure that the formula were were using was
A=Pe^rt.
That means, we have to plug it in the formula.
P= 7500
r= 0.029
t= 14
you calculate it and then to the nearest ten dollars, your answer will be
$11,260. :)
Using Exponential Function, the amount of money to the nearest $10 would be in the account after 14 years is $11,260.
What is Exponential function?Exponential function is "a function whose value is constant raised to the power of an argument, especially the function whose constant is e".
According to the question,
Ariana invested $7500 in an account paying interest rate 2.9% compounded continuously assuming no deposits or withdrawals are made.
In order to find amount of money after 14 years only if we use exponential function.
Formula to find amount of money after 14 years = P .\(e^(rt)\) where 'r' is the rate of interest and 't' is time period and 'P' is the Principal.
Amount of money after 14 years = P .\(e^(rt)\)
= (7500)\(e^(0.029)(14)\) [2.9% = \(\frac{2.9}{100}\) = 0.029]
= 7500\(e^(0.406)\)
= 7500 (1.5008) [The value of \(e^(0.406)\) = 1.5008]
= 11,256.
Hence, using Exponential Function, the amount of money to the nearest $10 would be in the account after 14 years is $11,260.

1) Note the the linearization of th function f(X) at a =1 is l(x) = 2x-3
2) since l(x) = 2x-3, f(1.01) is = - 0.98
Linearization is the process of converting a nonlinear function's gradient with respect to all variables into a linear representation at that moment.
for the above prompt , we have to use the formula:
l (x) = f(a) + f' (a) (x-a)
where (a) is the value fo the function at point a
and f' (a) is the derivative of the function evaluated at point a.
Using a = 1, f(a) becomes:
f(1) = 2 (1) ⁵ - 8 (1) + 5
f (1) =-1
f(x) = 10x⁴ -8
So f' (1 ) when evalutated will give us the slope of the tangent line at x =1
Thus,
f (1 ) = 10 (1)⁴ -8
= 2
Hence substituting all the values into th e linearization formula we get:
l(x) = f( 1) + f '(1) (x-1)
= -1 + 2 *( x-1 )
= -1 + 2x - 2
= 2x -3
This means that the linearization of the function f(x ) at a= 1 is l(x) = 2x-3
b) Given the l(x) above, f(1.01) gives us:
l(x) = 2x -3
= 2 (1.01) -3

Answer:
The literary magazine must pay $ 10 if poem is written by Gil, $ 20 if poem is written by Holly and $ 30 if poem is written by Ivan.
Step-by-step explanation:
The wage indicate the amount of money earned in hour for production of poems. If a literary magazine needs just one poem, then the cost will be the wage multiplied by time taken for the creation of the poem. There are three possibilities:
Gil
\(C = \left(10\,\frac{USD}{h})\cdot (1\,h)\)
\(C = 10\,USD\)
Holly
\(C = \left(10\,\frac{USD}{h}\right)\cdot (2\,h)\)
\(C = 20\,USD\)

f is graphed here as the black (solid) prangula and the transformed function g is graphed here as the green (dotted) prangula 1) Decribe the sequence of transformations from f to g2) use function notation to write g in terms of f
Notice that we can make an intermediate step between both graphs by moving the green graph three units to the left:
Notice that the horizontal lengths of the red graph and the blue graph are the same, but all the vertical lengths seem to have been multiplied by 2.
Since the blue graph (black, in the text) is called f and the transformation that takes the graph of f to the red graph is "multiplying by 2", then, the red graph is given by the expression:
\(2\cdot f(x)\)Since the green graph is a three-units shift to the right of the red graph, then it is given by the expression:
\(2\cdot f(x-3)\)Since the function whose graph is the green graph is called g, then:
\(g(x)=2\cdot f(x-3)\)Therefore:
1) The sequence of transformation that takes f to g is:
1.- A stretching in the y-direction by a factor of 2.
2.- A 3-units shift to the right.
2) In function notation, g is given in terms of f by: g(x) = 2f(x-3).

for two weeks because Jimmy John's has a delayed paying process. Everyone gets paid two weeks after they work to
give Human Resources time to prepare the tax information. Since James gets paid every two weeks, a)what is his
gross income for his checks? His pay was much less. It tums out, other people get his money first. He had to pay
Federal Income Tax. b)Use the chart on the back of the test to determine his FIT. He also has to pay State
Income Tax. Oklahoma has a flat 5% tax. c)What is his SIT at 5% of his paycheck? Also, something called FICA
was on his paystub. His employer told him it was a required 6.2% tax for Social Security Retirement and a 1.45%
tax for Medicare when he gets older. d)Find James' Social Security Tax. e)Find his Medicare Tax. What is the
amount of FICA Tax listed as being withheld(add together)? Next came the big schock. Apparently, the
Republican Party still hasn't ended required healthcare. Because of this, James has to pay for group insurance with
Jimmy John's. It is $100 every paycheck, g)what percent of James' gross income is this each month? Finally,
James looks at the other category. It has two deductions listed. First, it has Sandwich Union Body Dues. Annual
dues are $130. h)How much was taken out for SUB dues just this paycheck? The second charged deduction for
other was IRA Retirement. He remembers signing up because Jimmy Johns' offers a matching 5%. If James' is
maximizing the match, i)how much is being taken out for retirement from his paycheck? After going over all the
numbers with his boss, it looks like James' check is correct. j)How much was his net income? If these numbers
remain consistent through the year, k)how much will James bring home for the year? DWhat percent of his
expected salary is this? James was really looking forward to his big paycheck. He thought he would have enough
money to get a loan on a new car. m)Do you think he should try to get the loan or not? n>Explain your opinion.
