For the compound interest loan whose terms are given below, find the future value, or the amount due at the end of the specified time.
Principal: $5000
Interest rate: 4%
Compounding: Annually
Time: 4.5 years
Answers
The amount after 4.5 years for the principal amount $ 5000 at 4 % interest compounded annually will be $ 5956.13.
We are given that:
Principal = p = $ 5000
Interest rate = r = 4%
Compounding Annually
Time = n = 4.5 years
Now, we know that the formula for compound interest is:
Amount (A) = p ( 1 + r )ⁿ
Substituting the values in the formula, we get that:
A = 5000 ( 1 + 0.04)⁴°⁵
A = 5000 (1.04)⁴°⁵
A = 5000 (1.19)
A = $ 5956.13
Therefore, we get that, the amount after 4.5 years for the principal amount $ 5000 at 4 % interest compounded annually will be $ 5956.13.

The slope of the line relating Alyssa's sales to earnings is given by 0.15,the equation that gives Alyssa's daily earnings based on her total sales is y = 0.15x +80,the y-intercept of the line represents the part of Alyssa's earnings that doesn't depend on sales. It is Alyssa's fixed daily wage and the y-intercept is 80.
What is slope intercept form of line?The slope intercept form of a line is y=mx+c, where m is the slope of line.
a) The slope of the line relating Alyssa's sales to earnings is given by
slope = (change in earnings)/(change in sales)
Using the first two table entries, the slope is calculated as
slope = (110 -80)/(200 -10) = 30/200 = 0.15
The first entry in the table shows the y-intercept, the value of earnings (80) for zero sales. The slope-intercept form of the equation for a line is
y = slope*x + y-intercept
To answer the first question, we put the slope and intercept values in the appropriate spots in the equation.

The area of a rectangular wall of a bam is 120 square feet its length is 4 feet longer than twice its width. Find the length and width of the wad of the barn
Answers
Answer:
Length = 20 ft. Width = 6 ft.
Step-by-step explanation:
length =18 ft
Width = 7 ft
We know the area of the wall formula
A = length * width,
120 = (4 + 2x)x
120 = 4x + 2x²
2x² + 4x - 120 = 0
Divide by 2
x² + 2x - 60 = 0
x² + 8x - 6x - 60 = 0
x(x + 8) - 6(x + 10) = 0
(x - 6)(x + 10) (x + 8)= 0
By zero-product law, we know that:
Either, x - 6 = 0 ⇒ x = 6.
or, x + 10 = 0 ⇒ x = -10.
or x + 8 = 0 ⇒ x = -8
Since x is the width of the wall, it can not be negative. Thus we take x = 6.
∴ Width of the wall of the barn = 6 feet
Length of the wall of the barn =
4 + 2*6 = 4+ 12 = 18 feet.
Now we find the width by formula using length we found
2w + 4 = 18
2w = 14
w = 7

The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x.
In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain.
The whole set of values that the function's output can produce is referred to as the range. The set of values that might be a function's outputs is known as the co-domain.

What is the slope intercept form of a line ?
The equation of a line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.
From the given figure we can find out that the points are (x1.y1) = (-2 , 5) and (x2 , y2) = ( -1 , 3).
The equation of line in slope intercept form
y = mx + c
Where m is the slope, and c is the y-intercept.
We have points (-2, 5) and (-1,3). Thus , the slope (m) will be :
m = ( [tex]y_{2} - y_{1}[/tex] ) /( [tex]x_{2} - x_{1}[/tex] )
m = ( 3 - 5 ) / ( -1 + 2)
m = -2
Using this value to find out the equation of line we get :
y = -2x + c
Point (-2,5) means that when x = -2 then y = 5 , and we use this data to find value of c , which is the y- intercept ;
5 = -2 × -2 + c
c = 5 - 4
c = 1
So , in slope intercept form the equation of line will be ;
y = -2x + 1
Therefore , the equation of line in slope intercept form will be y = -2x + 1.

An owner's income from a successful manufacturing process producing goods for the market is referred to as a profit (business).
The owner's primary interest in the process of creating income through market production is represented by profit, which is an indicator for profitability. Different profit metrics are frequently used.Income generation and distribution must always be in balance in order for income to be produced in the market. Throughout the assessment period, the earned money is consistently dispersed as economic value to the production's stakeholders. The portion of the income formation that remains for the owner to keep after the income distribution process is known as the profit.The cost for supplies is $0.80 per DVD.
Let the company manufactured and sold x DVD s.
Now , total cost for x DVDs = 0.80 x + 1500
Total sell price for x DVDs = 1.59x
Profit = Sell price - cost price
Profit = 1.59x - 0.80x - 1500
profit = 0.79 x - 1500
Now the profit is made. Therefore profit>0
∴ 0.79 x - 1500 > 0
or , x > 1500 ÷ 0.79

A rolld of wool insulation is 114cm wide and 5.2m long. one roll costs £19.65. estimate the cost of the wool insulation required for a loft floor that is 4.5m by 10m
Answers
The cost of the wool insulation required for the loft floor is £149.16498
How to estimate the cost of the wool insulation required for the loft floor?The given parameters are
Roll of wool = 114 cm by 5.2 m
One roll = £19.65 per roll
The area of one roll is calculated as
Area = Length * Width
So, we have
Area = 114 cm x 5.2 m
Convert cm to m
Area = 1.14 m x 5.2 m
Evaluate the product
Area = 5.928 m^2
The cost of the required area of loft floor is
Total cost = Unit cost/Area of 1 roll x Area of floor
This gives
Total cost = £19.65/5.928 * 4.5 * 10
Evaluate the product
Total cost = £149.16498
Hence, the cost of the wool insulation required for the loft floor is £149.16498

In mathematics, a rate of something is simply the ratio between two related quantities which are expressed different units. While expressing the units of any rate, the word "per" is used to distinguish the units of the two measurements used to calculate the rate.
Here, we are given that a country has a population of 2.1 million.
2.1 million can be written as- 2,100,000
The number of fatalities experienced by the country = 4,310
This means that there where 4,310 fatalities per 2.1 million of the population.
The number of fatalities per 100,000 will be given as-
4,310/ 2,100,000 × 100,000

6. BUILDING A horse farm is developing a new indoor arena in a rectangular building. They want the width of the building to be 2y feet and the length to be 4y – 9 feet. Write an expression in simplest form to represent the area A of the building in terms of y.
Answers
The area of the building in terms of y in its simplest form is (8y^2-18)
Since the area of rectangular is
Area = Length x Breadth
From our Question,
The width of the rectangle building is 2y feet.
So, L = 4y - 9 feet
So, the area of the building in terms of y is
Area = L x B
= (4y-9)x 2y
= (8[tex]y^2[/tex] - 18y)
So, the area of the building in term of y in its simplest form is (8y^2 -18)

Answer:
2b) x < - 3
2e) x < 3 or x < -3
Step-by-step explanation:
Format for quadratic equations (the only difference in quadratic equations is that the equal sign is replaced with any of the inequality symbols (< , > , ≥ , and ≤)
ax² + bx + c = 0
- To factor quadratic inequalities (we're using 2b) as a demonstration)
1) Find two numbers that make the product equal to a×c (1×9) which is 9 and the sum that equals to b which is 6. Those two numbers in this case is positive 3 and positive 3
2) Spilt the middle term with those two numbers which are positive 3 and positive 3 so the inequality x² + 6x + 9 is going to become x² + 3x + 3x + 9
3) Take the common terms and simplify the common terms in this case the common terms are x and + 3 so it can be factored as (x + 3) and (x + 3)
To find each x make each term greater than 0 so it would be x + 3 < 0 and x + 3 < 0
4) Solve for x (it is the same way to solve x in inequalities as it were for equations which is doing inverse operations to order to islolate x) It would be x + 3 - 3 < 0 - 3 which is x < - 3
2e)
1) You essentially do the same steps for solving this question too but a shortcut way of doing factoring is to do the perfect square method which is to look a c which is 9 and if its a perfect squares you can factor it as (x+3) and (x-3) since not only is the 9 negative both of these terms when added cancel out each other.
2)To find x make everything < 0 so it would be x + 3 < 0 and x - 3 < 0
3) Solve for x it would be x + 3 - 3 < 0 - 3 and x - 3 + 3 < 0 + 3 . The roots are x < - 3 or x < 3
I hope this helps :)
