a) If x is the volume of a purchase before the discount is applied, write a piecewise definition for the discounted price D(x) of this purchase.
D(x)= x if 0≤x<300 enter your response here if 300≤x<1,000 0.95x if 1,000≤x<3,000 enter your response here if 3,000≤x<5,000 0.90x 5,000≤x
Answers
The piecewise function for the discounted price of the purchase is given by:
D(x) = 0.96x, 300≤x<1,000.D(x) = 0.95x, 1,000≤x<3,000.D(x) = 0.94x, 3,000≤x<5,000.D(x) = 0.9x, 5,000≤x.What is a piecewise function?A piecewise function is a function that has different definitions, depending on the input.
For $300≤x<$1,000, the discount is of 4%, hence the discounted price is 96% of the original price, that is:
D(x) = 0.96x, 300≤x<1,000
For $1,000≤x<$3,000, the discount is of 5%, hence the discounted price is 95% of the original price, that is:
D(x) = 0.95x, 1,000≤x<3,000.
For $3,000≤x<$5,000, the discount is of 6%, hence the discounted price is 94% of the original price, that is:
D(x) = 0.94x, 3,000≤x<5,000.
For $5,000≤x, the discount is of 10%, hence the discounted price is 90% of the original price, that is:
D(x) = 0.9x, 5,000≤x.

For distinct complex numbers \( \rm z_1,z_2, \cdots, z_{673},\) the polynomial

\( \rm {x}^{2019} + 20 {x}^{2018} + {19}x^{2017} + g(x),\)
where g(x) is a polynomial with complex coefficients and with degree at most 2016.
\( \rm The \: value \: of \left | \sum \limits_{1 \leq j < k \leq673 }z_{j} z_k\right| \)
can be expressed in the form m/n, where m and n are relatively prime positive integers. Find m+n.
Answers
Let
\(S = \displaystyle \sum_{1\le j<k\le673} z_jz_k\)
and
\(p_{\mu,\nu}(x) = (x-z_1)^\mu (x-z_2)^\mu \cdots (x-z_\nu)^\mu\)
The \(z_jz_k\) terms occur in the coefficient of the \(x^{\mu\nu-2}\) term, given by
\(\displaystyle \left[x^{\mu\nu-2}\right] p_{\mu,\nu} = \binom\mu2 \sum_{r=j}^\nu z_j^2 + \mu^2 \sum_{1 \le j < k \le \nu} z_jz_k\)
(essentially due to Vieta's formulas)
With \(\mu=3\) and \(\nu=673\), we have
\(\displaystyle \left[x^{2017}\right] p_{3,673} = \binom32 \sum_{j=1}^{673} z_j^2 + 3^2 S \\\\ ~~~~ \implies S = \frac{19}9 - \frac13 \sum_{j=1}^{673} z_j^2 \\\\ ~~~~ \implies S = \frac{19}9 - \frac13 \left(\left(\sum_{j=1}^{673} z_j\right)^2 - 2 S\right) \\\\ ~~~~ \implies S = \frac{19}3 - \left(\sum_{j=1}^{673} z_j\right)^2\)
The remaining sum on the right is the sum of the roots of \(\sqrt[3]{p_{3,673}(x)} = p_{1,673}(x)\).
Recall that the sum of the roots of a polynomial
\(P_n(x) = a_nx^n + a_{n-1}x^{n-1} + \cdots + a_0\)
is \(-\frac{a_{n-1}}{a_n}\). Then the sum of the roots of \(p_{3,673}(x)\) is -20, which is 3 times the sum of the roots (counting multiplicity) of \(p_{1,673}\), so
\(\displaystyle \sum_{j=1}^{673} z_j = -\dfrac{20}3 \\\\ ~~~~ \implies S = \frac{19}3 - \left(-\frac{20}3\right)^2 = -\frac{343}9 \\\\ ~~~~ \implies |S| = \frac{343}9, m=343, n=9 \implies m+n = \boxed{352}\)

Let (a, 0) and (0, b) denote the x- and y-intercepts of any tangent line to the curve √ x + √y = √ c. Find the number c so that a + b = 10.
Answers
The value of c that satisfies the condition a + b = 10 is 10.
To find the value of c such that the sum of the x- and y-intercepts of any tangent line to the curve √x + √y = √c is equal to 10, we can use the fact that the x-intercept occurs when y = 0, and the y-intercept occurs when x = 0.
First, let's find the x-intercept. When y = 0, we can substitute this value into the equation:
√x + √0 = √c
Simplifying, we have:
√x = √c
Squaring both sides of the equation, we get:
x = c
So, the x-intercept is given by (c, 0).
Next, let's find the y-intercept. When x = 0, we can substitute this value into the equation:
√0 + √y = √c
Simplifying, we have:
√y = √c
Squaring both sides of the equation, we get:
y = c
So, the y-intercept is given by (0, c).
Since we want the sum of the x- and y-intercepts to be equal to 10, we have:
c + 0 = 10
Simplifying, we find:
c = 10

Nolan Walker decided to buy a used snowmobile since his credit union was offering such low interest rates. He borrowed $2,700 at 3.5% on December 26, 2019, and paid it off February 21, 2021. How much did he pay in interest? (Assume ordinary interest and no leapyear.) (Use Days in a year table.) (Do not round intermediate calculations. Round your answer to the nearest cent.)
Interest Paid?
Answers
Using the formula for simple interest, it is found that he paid $119.87 in interest.
The simple interest formula is given by:
\(E = PIt\)
E is the amount of interest earned.P is the principal(the amount of money invested). I is the interest rate(yearly, as a decimal).t is the time, in years.In this problem:
Borrowed $2,700, thus \(P = 2700\)Interest rate of 3.5%, thus \(I = 0.035\)From December 26, 2019 to February 21, 2021, there were 423 days, thus the time in years is \(t = \frac{423}{365} = 1.2685\)Thus, the interest paid was of:
\(E = PIt = 2700(0.035)(1.2685) = 119.87\)
$119.87.

A Certain sum of money of simple
interest amount to $$1,300 ire 4 years
and to #11525 in 7 years - Find
the sum and the rate percent
Answers
The required rate of simple interest is 1.75%.
Here, we have,
(Principal + Interest) is a straightforward interest equation.
A = P(1 + rt)
Where: A is the sum of the accrued principal and interest.
Principal Amount is P.
I is the interest rate.
r is the annual percentage rate of interest, or R/100.
R is the annual percentage rate of interest; R = r * 100 t is the length of time involved in months or years.
Since I = Prt,
the initial formula A = P(1 + rt) evolved from A = P + I to A = P + Prt,
which may be represented as A = P(1 + rt).
Given: Principal is $1,300
Rate is 7% and the amount earned that is A-P is $159.25.
A = P(1 + rt)
Therefore substituting the values in the above mentioned equation, we get:
159.25= 1300(1+r×7)
On solving we get,
r= 1.75%

Selina is remodeling her home. She installed a low-flow toilet in her home that flushes 0.8 gallon each time. She replaced her showerhead with a low-flow showerhead that releases 1.5 gal/min. She flushes 12 times a day and showers for 10 minutes a day. On average, her appliances use 40.2 gal/day. Assuming no other appliance use, how much less water will she use than the average U.S. citizen?
Answers
The average U.S. citizen uses approximately 88 gallons of water a day.
What is Frequency?
Frequency is a measure of how often an event occurs within a given period of time. It is typically expressed as the number of occurrences of a given event per unit of time. Frequency can be used to measure a variety of phenomena such as the frequency of sound in a given environment or the frequency of a particular chemical element in a given sample.
Selina's low-flow toilet and showerhead will reduce her total water use to just 48.4 gallons per day, a savings of 39.6 gallons of water each day. This is a 44.8% reduction in her water consumption, saving her almost 40 gallons of water per day.
By making these improvements, Selina is helping to conserve a precious resource and limit her environmental impact. Not only is she helping to conserve water, but she is also saving money on her water bill. It is estimated that a typical household can expect to save about $170 annually by making these simple changes.
In addition to her low-flow fixtures, Selina can take additional steps to reduce her water consumption. She can install a water-efficient dishwasher, reduce the frequency of her laundry loads, and install a rain barrel to collect rainwater for gardening. By making these changes, she can reduce her water consumption even further and save even more money.
