Find the amount in a continuously compounded account for the given conditions.
principal: $ 6000 ; annual interest rate: 6.8 % ; time: 10 years
The amount after 10 years is $11,842.43
In continuous compounding the number of times by which compounding occurs tends to infinity.
In order to calculate the amount use the following formula
A= Pe^rt
where P represents the initial amount, e is the mathematical constant having value 2.7182, r is the rate of interest and t is the time period
Here the principal amount is $6000, r is 6.8 and time period t is 10 years
A = $6000 x 2.718⁽¹⁰ ˣ ⁶·⁸ %⁾
A = 6000 x 2.718⁽¹⁰ ˣ ⁶·⁸÷¹⁰⁰⁾
A = 6000 x 2.718 x 0.68
A = $ 11,842.43
Therefore the total amount calculated after 10 years is $ 11,842.43

Bron
b. How many hours did he take to drive one mile?
Graham drove 32.58 miles in one hour and it took 1.84 minutes to drive a mile
Miles Graham drove in 13 hours = 423 miles
Unitary method: A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary technique. It is a technique that we employ for the majority of math calculations.
Part a:
Miles driven in one hour = Total miles driven/Total no. of hours taken
= 423/13 = 32.58 miles
Part b:
Hours took to drive a mile = Total no. of hours taken/ Total miles driven

Step-by-step explanation:
X intercept is 1 and (-1, -4) find the equation of the line when given two points from the line.
Answer: y=2x-2
Step-by-step explanation:
X intercept is 1
Hence,
(1,0)
Thus,
(1,0) (-1.-4)
Equation of a straight line:
[tex]\displaystyle\\\boxed {\frac{x-x_1}{x_2-x_1}=\frac{y-y_1}{y_2-y_1} }[/tex]
x₁=1 x₂=-1 y₁=0 y₂=-4
[tex]\displaystyle\\\frac{x-1}{-1-1} =\frac{y-0}{-4-0} \\\\\frac{x-1}{-2} =\frac{y}{-4} \\\\[/tex]
Multiply both parts of the equation by -4:
(2)(x-1)=y
2x-2=y
Answer:
[tex]y=2x-2[/tex]
Step-by-step explanation:
The x-intercept is when the line crosses the x-axis, so when y = 0.
Therefore, the two points on the line are:
(1, 0)(-1, -4)To find the equation of the line when given two points from the line, first find the slope:
[tex]\textsf{slope}\:(m)=\dfrac{\textsf{change in $y$}}{\textsf{change in $x$}}=\dfrac{-4-0}{-1-1}=2[/tex]
Now substitute the found slope and one of the points (1, 0) into the point-slope form of a linear equation:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-0=2(x-1)[/tex]
[tex]\implies y=2x-2[/tex]
Therefore, the equation of the line is:

Three orders are placed at a sandwich shop. Four sandwiches, two beverages, and
one salad costs $40; two sandwiches, one beverage, and two salads costs $26; and
three sandwiches, three beverages, and two salads costs $38. How much does each
item cost?
The respective prices are given below as
The price of the sandwich is 20/3 dollars.
The salad may be purchased for a price of $16/3.
There is a fee of $2 for the drinks.
How can you build equations that are simultaneous?Let's say that the price of the sandwich is x.
Allow the price of salad to equal y.
Allow the price of drinks to equal z.
The new total for this meal is $46. It includes three sandwiches, three beers, and two salads. Thus;
3x + 3y + 2z = 40 ——- (eq 1)
The price of $29 covers two sandwiches, two drinks, and one salad.
Thus;
2x + 2y + z = 26 ——-(eq 2)
It will cost you $54 for four sandwiches, one drinks, and three salads. Thus;
4x + y + 3z = 38 ———-(eq 3)
The following are the results of concurrently solving the three equations:
x = 20/3
y = 16/3
z = 2
Therefore, the following is how much each item costs:
There is a charge of $20/3 for the sandwich.
The salad may be purchased for a price of $ 16/3.
There is a fee of $2 for the drinks.

The domain is all real numbers where x does not equal -2 and the range is all real numbers where f(x) does not equal -8
What is the domain and the range of a function?The domain of the function is the set of input values of the graph while the range of a function is the set of output values of the graph.
How to determine the domain and the range of the function?The given parameter is:
f(x) = (x^2 - 4x - 12)/(x + 2)
Based on the definition above, the range of a function is the set of y values of the graph while the domain is the set of x values of the graph
Set the denominator not equal to 0
So, we have
x + 2 ≠ 0
Evaluate
x ≠ -2
This means that the domain is all real numbers where x does not equal -2
For the range, we use a graphing calculator
From the graphing calculator, we have
f(x) ≠ -8
This means that the range is all real numbers where f(x) does not equal -8

The length of a rectangular garden is 5 feet less than twice its width. If the total distance around the garden is 44 feet, what are the length and width of the garden?
Answer: 78
Step-by-step explanation: multiply 44 by 2 because there are two sides on the rectangle and then you add 5 and 5 because yet again there are two sides so when you get your answer subtract 10 from the 88 and then you get 78 there is your explanation and equation
Rectangle with perimeter 44 ft has its length and breadth 13 ft and 9 ft respectively.
Dimension of rectangle : 13 × 9
Given, that perimeter of rectangle is 44 ft .
Now, perimeter of rectangle is given by:
P = 2(l + b)
l = Length of rectangle .
b = Breadth of rectangle.
Let the breadth of rectangle be 'x' m.
Then length will be (2x -5) ft.
Substitute the values in the perimeter formula,
[tex]44 = 2(x + 2x -5)\\22 = 3x -5\\x = 9[/tex]
Thus the breadth of rectangle is 9 ft .
Length of rectangle is 5 ft less than twice its breadth.
Length = 2(9) - 5
Length = 13 .

Write each expression in simplest form. (3x²/₃)⁻¹
The given expression would be simplified by solving for the negative exponent.
In this expression, the base term is 3x^2/3 and the exponent is -1.
A positive exponent tells us how many times a number is multiplied by itself while the negative exponent tells us how many times the base number has to be divided. It can also be described as the number of times the reciprocal of the base number is multiplied by itself.
The negative exponent rule states that: a^-x=1/a^x
Hence, applying the rule:
(3x^²/₃)^-1=1/(3x^²/₃)^1
Multiplying the power and simplifying,
1/(3x^²/₃)^1=1/3^1x^²/₃*1=1/3x^²/₃

What is the decimal equivalent to 2/9
Answer: The decimal equivalent to 2/9 = 0.22
Step-by-step explanation:
Define Decimal equivalent :
The decimals with the same number of decimal places are called like decimals. Equivalent decimals are decimal numbers that have the same value. For example, 3.42, 6.05 are like decimals as they have two decimal places. For example, 0.3 and 0.30 are equivalent decimals as they present the same value.
How do you find the equivalent decimal?
To find the decimal equivalent of a fraction, divide the numerator by the denominator. Because the number in the numerator is smaller than the number in the denominator, you have to place the decimal point after it and add zeros. Then complete long division.
Given data,
Find the decimal equivalent to 2/9.
To get a fraction into a decimal you have to divide the fraction. I was taught since the 2 is the numerator, it gets divided out of and the 9 is what you're dividing the 2.
so, we can write,
x = 2/9
where, numerator = 2
denominator = 9
Then, x = 2/9 = 0.22
Therefor, the decimal equivalent to 2/9 = 0.22

If Colton is 1.55 meters tall. At 1 p.m., he measures the length of a tree's shadow to be 44.35 meters. the height of the tree to the nearest hundredth of a meter. is 12.85 meters.
HeightFirst step is to find the distance that he is horizontally from the top of the shadow
Distance = 44.35 meters - 39 meters
Distance = 5.35 meters
Second step is to make use of equal proportion and find the height
5.35/ 1.55 = 44.35/x
5.35x = 1.55 × 44.35
x= 1.55 × 44.35 /5.35
