Sketch a graph of the polynomial function f(x) = –x3 + 5x2 – 2x – 8. Use the graph to complete the following:f is __________ on the intervals (–∞, 1/3) and (3, ∞)f is __________ on the interval (1/3, 3)f is __________ on the intervals (–∞, -1) and (2, 4)
To sketch the graph, we need to find the x-intercepts and y-intercepts.
To find the x-intercepts we solve the equation when y = 0.
That is
[tex]-x^3+5x^2-2x-8=0[/tex][tex]\begin{gathered} f(-1)=-(-1)^3+5(-1)^2-2(-1)-8=1+5+2-8=0 \\ \text{Hence} \\ x=-1\text{ is a zero of f(x)} \\ \Rightarrow\text{ x+1 is a factor of f(x)} \end{gathered}[/tex]Next, we find the result of :
[tex]\frac{f(x)}{x+1}[/tex][tex]\begin{gathered} So \\ \frac{-x^3+5x^2-2x-8}{x+1}=-x^2+6x-8 \end{gathered}[/tex]Now we solve
[tex]\begin{gathered} -x^2+6x-8=0 \\ \Rightarrow-x^2+2x+4x-8=0 \\ \Rightarrow-x(x-2)+4(x-2)=0 \\ \Rightarrow(4-x)(x-2)=0 \\ \Rightarrow x=4\text{ or 2} \end{gathered}[/tex]So the zeros of f(x) are -1, 2, and 4
Next, we find the stationary points.
[tex]\begin{gathered} \frac{df(x)}{dx}=-3x^2+10x-2 \\ \text{When }\frac{df(x)}{dx}=0,\text{ we have} \end{gathered}[/tex][tex]\begin{gathered} -3x^2+10x-2=0 \\ \text{Dividing through by -3 we have} \\ x^2-\frac{10}{3}x+\frac{2}{3}=0 \end{gathered}[/tex][tex]\begin{gathered} (x-\frac{5}{3})^2-(-\frac{5}{3})^2-2=0 \\ \Rightarrow(x-\frac{5}{3})^2=2+\frac{25}{9}=\frac{43}{9} \\ \Rightarrow x=\frac{5\pm\sqrt[]{43}}{3} \\ \Rightarrow x=2.55\text{ or }0.78 \end{gathered}[/tex][tex]\frac{d\frac{df(x)}{dx}}{dx}=-6x+10[/tex]At x = 2.55
[tex]\frac{d\frac{df(x)}{dx}}{dx}=-6(2.55)+10=-5.3<0[/tex]Hence we have a maximum point at x = 2.55
[tex]\frac{d\frac{df(x)}{dx}}{dx}=-6(0.78)+10=5.32>0[/tex]Hence, there is a minimum point at x = 0.78
[tex]\begin{gathered} f(0.78)\text{ = }-6.99 \\ f(2.550=2.83 \end{gathered}[/tex][tex]\begin{gathered} To\text{ check the intervals where the function increasing or decreasing} \\ \text{For x < 0.78 } \\ \frac{df(x)}{dx}=(x-0.78)(x-2.83)\text{ is positive} \\ \text{For 0.78 < x < 2.83 } \\ \frac{df(x)}{dx}=(x-0.78)(x-2.83)\text{ is negative} \\ \text{For x > 2.83} \\ \frac{df(x)}{dx}=(x-0.78)(x-2.83)\text{ is positive} \end{gathered}[/tex]This implies that
f is increasing on the intervals (–∞, 1/3) and (3, ∞)

If Patriciana has 4 more dimes than nickels and they have a combined value of 100 cents, how many of each coin does she have?
Patriciana has (20/9) nickels and (80/9) dimes of coins .
Evaluation for the number of dimes and nickels.There are 5 cents in a nickel and 10 cents in a dime.
Let the number of number of nickels be represented by the letter x, so that the number of dimes Patriciana has will be 4x.
So, 5x cents + 10 × 4x cents = 100 cents
5x cents + 40 cents = 100 cents
45x cents = 100 cents
divide through by the coefficient of x
x = 100cents/45cents
x = 20/9 by simplification,
and the number of dimes is calculated by putting 20/9 for x in 4x.
Hence, the number of dimes is 4(20/9) = 80/9 and that of nickels is 20/9.

We have to find the probability of picking a 7 and then picking a 7.
Explanation:
When you pick the first card there are four possibilities out of which only one card is numbered as 7.
Therefore, the probability of picking a 7 is
[tex]\frac{1}{4}[/tex]Before picking the second card you have put back the first card. So when you pick the second card there are four possibilities out of which only one card is numbered as 7.
Therefore, the probability of picking a 7 is

A basket contains 5 pieces of paper numbered from 1 to 5. A hat contains the letters A, B, C and D. If a blindfolded person picks a number and then a letter, what is the probability that the number is greater than 3 AND the letter is C?
We have a basket and a hat.
The basket has the numbers 1, 2, 3, 4 and 5.
The hat contains the letters A, B, C and D.
We have to calculate the probabiltiy of drawing a number that is greater than 3 from the basket and drawing the letter C from the hat.
We have two events:
- Drawing a number greater than 3 from the basket
- Drawing a C from the hat
They are independent as the probability of each on does not depend on the outcome of the other event.
Then, we can calculate the probability of the two events happening together as the product of its probabilities:
[tex]P(n>3&l=C)=P(n>3)\cdot P(l=C)[/tex]The probability of drawing a number greater than 3 can be described as 2/5, as we have 2 numbers greater than 3 (4 and 5) out of 5 numbers in the basket.
The probability of drawing a letter C can be described as 1/4, as we have one letter C out of 4 letters available.
Then, we can calculate the probability as:
[tex]\begin{gathered} P(n>3&l=C)=P(n>3)\cdot P(l=C) \\ P(n>3&l=C)=\frac{2}{5}\cdot\frac{1}{4}=\frac{2}{20}=\frac{1}{10} \end{gathered}[/tex]Answer: the probability is 1/10 or 0.1.

your gross income is 4520.00 your deductions are FICA (7.65%), federal tax withholding (11.75%), and state tax withholding (8.5%). Your fixed expenses are 30% of your realized income. You saved 5 months' worth in an emergency fund, placing 75% in a 60-day CD at a 5.25% APR and the rest in a regular savings account at a 3.8% APR. How much is the total interest earned between both accounts in 60 days?
The total interest earned between both accounts in 60 days is $92.01.
What is the interest?Given gross income = $4520/ month
Deductions = FICA+federal withholding + state with holding
Deductions = 7.65%+ 11.75%+8.5%= 27.9%
Total deductions = 27.9% of 4520= $1261.08
Net income = Gross income - Deductins = 4520-1261.08= $3258.92
Now 30 % of these are fixed expenses
Fixed expenses = 30% of 3258.92= $977.676
Amount left for month = 3258.92-977.676= $2281.244
5 months worth = 5*2281.244= $11406.22
Total money in the emergency fund = $11406.22
Since 75% in CD, amount imvested = 75% of 11406.22= 8554.665
APR= 5.25%
Number of days = 60
A= P*(1+r) ^n
Assuming they compound daily
r= 0.0525/365= 0.0001438
n= 60
A= 8554.665*(1+0.0001448) ^60
A= $8628.81
Regular savings:
25% in RS, Amount invested = 25% of 11406.22= 2851.55
APR= 3.8%
Number of days = 60
A= P*(1+r) ^n
Assuming they compound daily
r= 0.038/365= 0.0001041
n= 60
A= 2851.55*(1+0.0001041) ^60

At the local pizzeria, a slice of pizza costs $3.00. if there are eight slices in one pizza . how much would two whole pizzas cost?
Answer:
48 dollars
Step-by-step explanation:
3 x 8 = 24
24 x 2 = 48
Two whole pizzas will cost forty-eight dollars
Answer:
48 dollars
Step-by-step explanation:
because for each slice is 3 dollars and there is 8 slices in 1 pizza so 8*3=24 so for 1 whole pizza its 24 dollars and because we want 2 we multiply it by 2 so 24*2= 48 so for 2 whole pizzas it equals 48 dollars.
A easier way, in 2 pizzas there is a total of 16 slices so 16*3= 48
