A company plans to sell a new type of vacuum cleaner for $280 each. The company’s financial planner estimates that the cost, y, of manufacturing the vacuum cleaners is a quadratic function with a y-intercept of 11,000 and a vertex of (500, 24,000). Which system of equations can be used to determine how many vacuums must be sold for the company to make a profit?

Answer:
StartLayout Enlarged Left-Brace 1st Row y = 280 x 2nd Row y = negative 0.052 (x minus 500) squared + 24,000 EndLayout
Step-by-step explanation:
Given that:
Cost per cleaner = $280
The cost of x vacuum cleaners will be :
Cost per cleaner * number of cleaners
$280 * x
= $280x
The general vertex firm equation :
y-k = a(x-h)^2
Vertex = (500, 24000) ; Vertex = (h, k)
h = 500 ; k =24000 y= 11000, x = 0
y intercept = 11000
Plugging the values :
11000 - 24000 = a(0 - 500)^2
- 13000 = a(-500)^2
-13000 = a * 250000
a = - 13000 / 250000
a = - 0.052
Hence,
y - 24000 = a(0 - 500)^2
y = - 0.052(0 - 500)^2 + 24000

what is the Y intercept
y= 4x - 9
Answer:
b = –9
Step-by-step explanation:
First, refer to the slope-intercept formula:
y = mx + b
In this formula, m is the slope and b is the y-intercept.
That means in y = 4x – 9, the b variable is –9, which is the y-intercept.
Answer: the answer is A. because the y intercept is -9.

[tex] \huge{ \boxed{ \bold{ \tt{2 \: \frac{7}{15} }}}}[/tex]
Step-by-step explanation:
[tex] \tt{5 \frac{4}{5} - 3 \frac{1}{3} }[/tex]
Convert the mixed number into improper fraction
[tex] \tt{↦ \: \frac{5 \times 5 + 4}{5} - \frac{3 \times 3 + 1}{3} }[/tex]
[tex] \tt{↦ \: \frac{25 + 4}{5} - \frac{9 + 1}{3}} [/tex]
[tex] \tt{ ↦ \: \frac{29}{5} - \frac{10}{3} }[/tex]
While performing the addition or subtraction of unlike fractions , you have to express the given fractions into equivalent fractions of common denominator and add or subtract as we do with like fractions. Thus, obtained fractions should be reduced into lowest terms if there are any common on numerator and denominator. But in case of improper fraction, it needs to be deduced on mixed fraction. Now,
Take the L.C.M of 5 and 3
prime factors of 5 = 1 × 5
prime factors of 3 = 1 × 3
L.C.M = Common factors × Remaining factors
= 1 × 5 × 3
= 15
[tex] \tt{↦ \frac{29 \times (15 \div 5)}{15} - \frac{10 \times (15 \div 3)}{15} }[/tex]
[tex] \tt{↦ \: \frac{29 \times 3}{15} - \frac{10 \times \: 3 }{15} }[/tex]
[tex] \tt{↦ \: \frac{87}{15} - \frac{30}{15}} [/tex]
While performing the addition or subtraction of like fractions , you just have to add or subtract the numerator respectively in which the denominator is retained same.
[tex] \tt{ ↦ \: \frac{87 - 30}{15} }[/tex]
[tex] \tt{↦ \: \frac{37}{15} }[/tex]
Convert the improper fraction into mixed fraction.
[tex] \tt{↦ \boxed{ \tt{ 2 \frac{7}{15} }}}[/tex]
And we're done!

P(t) model the number of people at the beach
in Rio de Janeiro, Brazil, when it's t hours after
midnight on a certain day. When did the
number of people increase faster? *
Answer:
A, Between 9 and 10 am
Step-by-step explanation:
The math is simple. between 9 and 10 theres 1 hour, and between 28 and 67 there are 39 P(t).
Between 10 and 15 there are 5 hours, and between 67 and 212 there are 145 P(t), which divided by 5 is 29.
You divide by 5 to get the same amount of hours to compare both
9-10 am= 39
10-15am/pm= 29
Therefore, the number of people increased faster between 9 and 10 am.
The rate of increase of population is faster between t = 9 to t = 10.
What is the ratio of two numbers?The ratio of two numbers a and b can be written as a : b = a/b.
The ratio of two quantities is the unit rate of one quantity with respect to the other.
The table for the population and time can be formed as follows,
Population Time in hours
28 9
67 10
212 15
Now, the increase in population can be obtained by taking the ratios as follows,
Increase in population between t = 9 to t = 10 is given as,
(67 - 28) ÷ (10 - 9)
⇒ 39
And, between t = 10 to t = 15, it is given as,
(212 - 67) ÷ (15 - 10)
⇒ 145 ÷ 5 = 29
Thus, the rate of increase is more from t = 9 to t = 10.
Hence, the faster increase is given in time interval of t = 9 to t = 10.

Then the temperature drops F from 9 A.M. to 10 A.M. Write an expression that represents the change in temperature from 8 A.M. to 10 A.M. for each city. Simplify and interpret each sum. Use pencil and paper. Which city has the greater change in temperature? Which expression represents the change in temperature for City A?
Here is the full question.
In city A, the temperature rises 9° F from A.M to 9 A.M. Then the temperature drops 8°F from 9 A.M. to 10 A.M. in city B, the temperature drops 1°F from 8 A.M. to 9 A.M. Then the temperature drops 3°F from 9 A.M. to 10 A.M.
Write an expression that represents the change In temperature from 8 A.M. to 10 A.M for each city. Simplify and interpret each sum. Use a pencil and paper. Which expression represents the change in temperature for city A?
Answer:
In City A, the expression for the change in temperature is = 9 + (-8)
The amount the temperature changes for City A = 1°F
In City B, the expression for the change in temperature is -1 + (-3)
The amount the temperature changes for City B = -4°F
Thus, City A has a greater change in temperature.
Step-by-step explanation:
From the information above; Given that:
In City A, the rise in temperature from 8 A.M to 9 A.M is = 9°F
In City A, the drop in temperature from 9 A.M to 10 A.M = 8°F
Similarly;
In City B, the drop in temperature from 8 A.M to 9 A.M = 1°F
In City B, the drop in temperature from 9 A.M to 10 A.M = 3°F
∴
For City A
The temperature change from 8 A.M to 10 A.M are :
8 A.M to 9 A.M = +9°F
9 A.M to 10 A.M = -8°F
In conclusion, The sum for the change from 8 A.M to 10 A.M = 9 + (-8) = 1°F
For City B
The temperature change from 8 A.M to 10 A.M are:
8 A.M to 9 A.M = -1°F
9 A.M to 10 A.M = -3°F
In conclusion, The sum for the change from 8 A.M to 10 A.M = -1 + (-3) = -4°F

Tom would like to take out a secured loan to help pay for a vacation this summer. He has offered his car as collateral.
His car is worth $3,500. His bank can offer loans for 80% of collateral value. The vacation he has planned will cost
$4,750. Approximately how much additional collateral will Tom need to offer in order to borrow enough to go on his
vacation as planned?

Tom will need to offer additional collateral of C. $2,437.50 to borrow enough for his planned vacation.
What is collateral?Collateral refers to a valued property or financial security offered by the borrower to the lender to guarantee repayment of a loan.
Lenders sell collaterals when the borrowers fail to comply with their loan terms.
How is the additional collateral determined?Car's value = $3,500
Collateral value in percentage = 80%
Car's collateral value = $2,800 ($3,500 x 80%)
Planned cost of vacation = $4,750
Additional cost to meet vacation cost = $1,950 ($4,750 - $2,800)
Additional collateral value to meet target = $2,437.50 ($1,950/80%)
Total collateral that Tom needs to offer = $5,937.50 ($3,500 + $2,437.50)
80% of $5,937.50 = $4,750
Another way is to work with the planned cost and the collateral percentage offered by Tom's bank:
Planned cost of vacation = $4,750
Collateral value in percentage = 80%
Total collateral to be offered by Tom = $5,937.50 ($4,750/80%)
Car's collateral value = $3,500
Additional collateral value = $2,437.50 ($5,937.50 - $3,500)
Thus, Tom needs additional collateral of C. $2,437.50.

The region bounded by y = − 1x^2 + 3x + 18 , x = 0 and y = 0 is rotated about the y -axis. Find the volume of this solid of revolution:
Answer:
The volume of the solid V = 41601.6 π
Step-by-step explanation:
From the given information:
The volume of the shaded region bounded by rotating the shaded region about the y-axis is: dV
[tex]dV = \pi (-1x^2 +3x+18)^2 ((x+dx)^2 -(x)^2)[/tex]
[tex]dV =2 \pi x (-1x^2 +3x+18)^2 \ . dx[/tex]
[tex]dV =2 \pi x (-1x^2 +3x+18) ( -1x^2 +3x + 18). dx[/tex]
[tex]dV =2 \pi x (1x^4 -3x^3 -18x^2 -3x^3 +9x^2 +54x -18x^2 +54x + 324 ) \ .dx[/tex]
[tex]dV =2 \pi x (1x^4 -3x^3-3x^3 -18x^2 +9x^2 -18x^2 +54x +54x +324) \ .dx[/tex]
[tex]dV =2 \pi x (1x^4 -6x^3 -27x^2 +9x^2+ 108x +324) \ .dx[/tex]
[tex]\implies \int ^V_o \ dv = 2 \pi \int ^6_0 (1x^5 -6x^4 -27x^3+108x^2 +324x) \ dx[/tex]
[tex]V = 2 \pi \begin {bmatrix} \dfrac{1x^6}{6} - \dfrac{6x^6}{5} - \dfrac{27x^4}{4}+ \dfrac{108x^3}{3}+ \dfrac{324x^2}{2} \end {bmatrix}^6_0[/tex]
[tex]V = 2 \pi \begin {bmatrix} \dfrac{1(6)^6}{6} - \dfrac{6(6)^6}{5} - \dfrac{27(6)^4}{4}+ \dfrac{108(6)^3}{3}+ \dfrac{324(6)^2}{2} -0\end {bmatrix}[/tex]
