The dollar value v (t) of a certain car model that is t years old is given by the following exponential function.
V (t) = 26,000 (0.84)^t
Find initial value of the car and the value after 11 years. Run your answers to the nearest dollar is necessary.
Initial value: $26,000
Value after 11 years: $_____
Answer:
$ 3820
Step-by-step explanation:
When the car is new, it is 0 year old. It means, t = 0
Initial value = 26,000 (0.84)^0 = 26,000(1)
Initial value = $ 26000
Similarly, when car is 11 year old, t = 11
=> 26000(0.84)¹¹ = 26000(0.14691)
≈ $ 3819.842
≈ $ 3820 (round to near ten)

A group of 10 people is choose a chairperson and vice-chairperson. They put all 10 peoples names into a bar. The first name drawn becomes chair. The second name drawn becomes vice-chair. How many possible combinations of chair and Vice-chair are there ?
Answer:
90
Step-by-step explanation:
A group of 10 people is choose a chairperson and vice-chairperson. They put all 10 peoples names into a bar. The first name drawn becomes chair. The second name drawn becomes vice-chair. How many possible combinations of chair and Vice-chair are there ?
This is calculated using the Permutation formula
nPr = n!/(n - r)!
Where:
n = 10 people
r = 2 = 2 positions to be filled , Chairman and Vice chairman
Hence:
10P2 = 10!/(10 - 2)!
= 90 ways

how does using scientific notation help when computing with very small or very large numbers
Answer:
It abbreviates or shortens the numbers that you are working with making them easier to do calculations with.
Step-by-step explanation:
Example : 10,000 in scientific notation = 1.0x10^4
1,000,000 = 1.0x10^6

4 +y = 12. Substitute 8 for x.
Answer:
where should I substitute 8 for x? if its like this 4(8)+y=12 than its y=-20
Step-by-step explanation:
25a² - 16b² when a = --2 and b = 3
25a² - 16b²
25*-2² - 16*3²
25*4 - 16*9
100 - 144

2x - 8 = 12 - 4x
solve for variable
Answer:
x = [tex]\frac{10}{3}[/tex] or [tex]3\frac{1}{10}[/tex]
Step-by-step explanation:
2x - 8 = 12 - 4x
1) Add 8 on boths sides:
2x - 8 + 8 = 12 - 4x + 8
2x = 20 - 4x
2) Add 4x to both sides:
2x + 4x = 20 - 4x + 4x
6x = 20
3) Divide 6 on both sides
[tex]\frac{6x}{6} = \frac{20}{6}[/tex]
x = [tex]\frac{10}{3}[/tex] or [tex]3\frac{1}{10}[/tex]

What is an equation of the line that passes through the points (5, 5) and (5, -8)
Answer:
Write the problem as a mathematical expression. (5,5), (5,−8)
Use y=mx+b to calculate the equation of the line, where m represents the slope and b represents the y-intercept. To calculate the equation of the line, use the y=mx+b format.
Slope is equal to the change in y over the change in x , or rise over run.
m=(change in y)/(change in x)
The change in x is equal to the difference in x-coordinates (also called run), and the change in y
is equal to the difference in y-coordinates (also called rise).
m=(y2−y1) / (x2−x1)
Substitute in the values of x and y
into the equation to find the slope.
m=(−8−(5)) / (5−(5))
Finding the slope m.
Undefined
x=5
Step-by-step explanation:
Answer:
m = undefined

Coordinates (x, y)Slope Formula: [tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]Step-by-step explanation:
Step 1: Define
Point (5, 5)
Point (5, -8)
Step 2: Identify
(5, 5) → x₁ = 5, y₁ = 5
(5, -8) → x₂ = 5, y₂ = -8
Step 3: Find slope m
Simply plug in the 2 coordinates into the slope formula to find slope m
Substitute in points [Slope Formula]: [tex]\displaystyle m=\frac{-8-5}{5-5}[/tex][Slope] Subtract: [tex]\displaystyle m=\frac{-13}{0}[/tex]Here we see that we have a number divided by 0. Since we know that we cannot divide any number by 0, our slope will be undefined. This will be a vertical line on a Cartesian plane of x = 5.

Solve for n. 5^{n} = 5^[11] x 5^ [3]
Answer:
n = 14
Step-by-step explanation:
[tex]5^n = 5^{11} * 5^3[/tex]
simplify the right side
[tex]5^n = 5^{14}[/tex]
Then you can easily see that
[tex]n = 14[/tex]
Answer:
n = 14
Step-by-step explanation:
[tex]a^{x}*a^{y}=a^{x+y}\\\\5^{n} = 5^{11}*5^{3}\\\\5^{n} = 5^{11+3}\\\\5^{n}=5^{14}\\\\[/tex]
n = 14
While growing bacteria in a laboratory Petri dish, a scientist notices the number of bacteria over time. The observations are shown in the table.
Number of bacteria
Number of minutes
from initial state
0 4
5 128
10 4096
15 131072
What function can be used to describe the number (n) of bacteria after 2 minutes?
Answer:
The function that can be used to describe the number (n) of bacteria after 2 minutes is;
[tex]P = 4 \cdot e^{\left(\dfrac{ln(32)}{5} \times 2\right)} \approx 4 \cdot e^{\left(0.693\times 2\right)}[/tex]
Step-by-step explanation:
The data in the table are presented as follows;
Number of bacteria; 4, 128, 4,096, 131,072
Number of minutes from initial state; 0, 5, 10, 15
The general equation for population growth is presented as follows;
[tex]P = P_0 \cdot e^{r\cdot t}[/tex]
Where;
P = The population after 't' minutes
P₀ = The initial population
r = The population growth rate
t = The time taken for the growth in population numbers
At t = minutes. we have;
[tex]4 = P_0 \cdot e^{r\times0} = P_0[/tex]
∴ P₀ = 4
At t = 5, we have;
[tex]128 = 4 \cdot e^{r\times 5}[/tex]
[tex]\therefore e^{r\times 5} = \dfrac{128}{4} = 32[/tex]
[tex]ln\left(e^{r\times 5}\right) = ln(32)[/tex]
∴ r × 5 = ㏑(32)
r = ln(32)/5 ≈ 0.693
The number (n) of bacteria after 2 minutes is therefore;
[tex]P = 4 \cdot e^{\left(\dfrac{ln(32)}{5} \times 2\right)} \approx 4 \cdot e^{\left(0.693\times 2\right)}[/tex]

Three square flower beds with side of 2m are dug in a rectangular piece of land whose length is 5.2 m and width is 4.8 m. What is the area of the remaining land?
Answer: 12.96 m²
Step-by-step explanation:
The area of the piece of land that the flower beds were dug in is:
= Length * width
= 5.2 * 4.8
= 24.96 m²
The flower beds were 3 in number and all had the shape of a square.
Their area is:
= 3 * (Length * width)
= 3 * ( 2 * 2)
= 3 * 4
= 12 m² for all three flower beds
Remaining land:
= 24.96 - 12
= 12.96 m²
