Answer:
240000
Step-by-step explanation:
Represent the exponential equation.
[tex]10000 (5 {t}^{ \frac{2}{3} } + 4) = [/tex]
Replace 8 with t
[tex]10000(5(8) {}^{ \frac{2}{3} } + 4)[/tex]
[tex]10000(5 \times 4 + 4) [/tex]
[tex]10000(24) = 240000[/tex]
The population of the town after 8 month will be 2,40,000.
What is exponential growth?
Exponential growth is a pattern of data that shows greater increases with passing time, creating the curve of an exponential function.
Let P be the population of the town after 8 months
According to the given question
The current population of the town = 10,000.
Also, the population of the town is changing at the rate of [tex]4+5t^{\frac{2}{3} }[/tex].
Therefore, the population of the town after 8 month is given by the exponential function
[tex]P = 10000(4+5t^{\frac{2}{3} } )[/tex]
Substitute t =8 in the above equation
⇒[tex]P = 10000(4 + 5(8)^{\frac{2}{3} } )[/tex]
⇒[tex]P = 10000(4 + 5(2^{3}) ^{\frac{2}{3} } )[/tex]
⇒[tex]P = 10000(4+5(4))[/tex]
⇒[tex]P = 10000(24)[/tex]
⇒[tex]P = 240000[/tex]
Hence, the population of the town after 8 month will be 2,40,000.

Step-by-step explanation:
The required triangle is attached below :
The triangle AFE has it's by the mid segment as BD ;as B is the mid-point of line EA ; and D is the mid-point of line FA ;
HENCE, The Length of the midsegment BD = 1/2FE
Hence, BD =. 1/2 * 23.5

show that the line x-y+2=0 and the line joining the points (4,6) and (10,12) are parallel to each other
x-y+2=0
-y= -x-2
y=x+2
In order for the other line to be parallel, the slope has to be the same.
(12-6)/(10-4)= 6/6= 1
Both slopes are the same, meaning it is parallel.

Answer:
The x interceprs are (-3,0) and (2,0)
Step-by-step explanation:
The reason is that when you plug in a -3 in the left parentheses it would become 0, and any number times 0 would be zero, making the equation equal to zero. The same would be true for the terms in the right parentheses, plugging in a two would make it equal to zero. This would make the entire equation equal to zero, finding you the x intercepts.

A. 10.972
B. 11.000
C.11.172
D.11.983
9514 1404 393
Answer:
B. 11.000
Step-by-step explanation:
The function looks like a reflected and translated exponential function with a horizontal asymptote near y = 11.000. The rate of change is decreasing so fast that the next value is expected to be very near 10.994. The closest one among the answer choices is 11.000.
_____
First differences are 0.811 and 0.011. The latter is about 0.0136 times the former. At that rate of change, we expect the next first difference to be about 0.000149, which would make the next number in sequence be about 10.9941—very little change from 10.994.
Clearly, first differences are not constant, so the function is not linear. Ratios of the numbers are not constant, so this is not an exponential (geometric) sequence. A reflected exponential function of the type described is a good fit.
With only 3 points given, the rule is not at all obvious. The next term could legitimately be anything you like, and a rule could be made that would fit it.

Fisk Corporation is trying to improve its inventory control system and has installed an online computer at its retail stores. Fisk anticipates sales of 84,500 units per year, an ordering cost of $12 per order, and carrying costs of $1.20 per unit.
Required:
a.What is the economic ordering quantity?
b. How many orders will be placed during the year?
c. What will the average inventory be?
d. What is the total cost of ordering and carrying inventory?
Answer: A) Economic ordering quantity ==$1,300
B)Orders placed during the year= 65 orders
C)average inventory= 650units
D)total cost of ordering and carrying inventory= $1,560
Step-by-step explanation:
A) Economic ordering quantity =[tex]\sqrt{2 x Annual demand x ordering cost /carrying cost}[/tex]
=[tex]\sqrt{2 x 84,500 x 12} /1.20[/tex]
=[tex]\sqrt{1,690,000}[/tex]
=$1,300
B)Orders placed during the year= Annual demand ÷ economic order quantity
= $84,500 ÷ 1,300 units
= 65 orders
C)average inventory= Economic order quantity ÷ 2
= 1,300 units ÷ 2
=650units
D)total cost of ordering and carrying inventory
Ordering cost = Number of orders × ordering cost per order
= 65 orders × $12
= $780
Carrying cost = average inventory × carrying cost per unit
= 650 units × $1.20
= $780
The total would be = $780 + $780 = $1,560

The domain is the list of the first numbers of the ordered pairs. If there are any duplicates, the relation is not a function. Here, the first numbers are {6, -9, 1}. Most folks find it convenient to list them in numerical order:
{-9, 1, 6} . . . . domain of G

what is the value of f'(6) if the formula is f(x)=-8x-3
Explanation:
Applying the derivative to f gets us
f(x) = -8x - 3
f ' (x) = -8
The fact that f(x) being linear directly means that the derivative is simply the slope value. No matter what we replace x with, the result is always -8.
Answer:
f'(6) = -8
Step-by-step explanation:
f(x)=-8x-3
First find the derivative of the function
f'(x) = -8
This is a constant so when x=6 it will be -8
f'(6) = -8

Match each subtraction of complex numbers to its simplified difference.
Here are the complex numbers with their simplified differences
(7 -3i) - (6 - 4i) = 1 + i
(4 + 3i) - (6 +2i) = -2 - i
(4 + 5i) - (3 - 4i) = 1 + 9i
(5 + 4i) - (9 + i) = -4 + 3i
A complex number is when a real number and an imaginary number are added together
Complex numbers are usually in the form : a + bi
where a and b are real numbers and i is an imaginary number
An example of a complex number:
in this complex number : (7 -3i)
7 and 3 are real numbers while i is the imaginary number
How to simplify complex numbers
In order to simplify these set of complex numbers, remember that when there is a bracket in mathematics it signifies multiplication.
Here are the set of rules that guide multiplication :
1. When a negative value is multiplied by a positive value, the value becomes a negative value
For example, -1 x 1 = -1
2. When a positive value is multiplied by a positive value, the value remains a positive value
For example, 1 x 1 = 1
3. When a negative value is multiplied by a negative value, the value becomes a negative value
For example,-1 x -1 = 1
Solution to the questions:
Using the above information, the complex numbers can now be simplified
1. (7 -3i) - (6 - 4i)
this above equation becomes :
7 - 3i - 6 + 4i
add like terms together
7 - 6 - 3i + 4i = 1 + i
2. (4 + 3i) - (6 +2i)
this above equation becomes :
4 + 3i - 6 - 2i
add like terms together
4 - 6 +3i - 2i = -2 - i
3. (4 + 5i) - (3 - 4i)
this above equation becomes :
4 + 5i - 3 + 4i
add like terms together
4 - 3 + 5i + 4i = 1 + 9i
4. (5 + 4i) - (9 + i)
this above equation becomes :
5 + 4i -9 -i
add like terms together
5 -9 + 4i - i = -4 + 3i
In order to solve for complex numbers remember that a bracket in mathematics means that a multiplication operation should be carried out. Also, pay cognisance to the rules guiding the multiplication of negative and positive numbers
