what is interest ?Simple interest is calculated by dividing the principal by the interest rate, the passage of time, and other elements. The formula used in marketing is simple return = principal + interest + hours. Using this approach, interest may be calculated most easily. The most common way to calculate interest is as a percentage of the principal balance. If he borrows $100 from a friend and agrees to pay it back with 5% interest, for instance, he will only pay his proportion of the 100% interest. $100 (0.05) = $5. You must pay interest when you borrow money and charge interest when you lend it. The majority of the time, interest is calculated as an annual percentage of the loan balance. This proportion is referred to as the loan's interest rate.

For the linear equation y = -3.5x + 50 the graph is plotted with points (0,50) and (14.28,0).
What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
The linear equation is y = -3.5x + 50.
An arcade deducts 3.5 points from a 50-point game card for each game played.
The graph will represent the x axis as number of games played.
The graph will represent the y axis as points earned.
Substitute the value x = 0 in the equation -
y = -3.5(0) + 50
y = 50
The coordinate point is (0,50).
Substitute the value y = 0 in the equation -
0 = -3.5x + 50
-50 = -3.5x
x = 14.28
The coordinate point is (14.28,0).
Plot both the coordinate points and join the line.
Therefore, the graph is plotted for the linear equation.

Explain Maxima and Minima in mathematics?Maxima and Minima are known as the extrema of a function. Maxima and minima are the maximum or the minimum value of a function within the given set of ranges. For the function, under the entire range, the maximum value of the function is known as the absolute maxima and the minimum value is known as the absolute minima.Local Maxima : A point x = b is a point of local maximum for f(x) if in the neighborhood of b i.e in (b−, b+) where can be made arbitrarily small, f(x) < f(b) for all x ∈ (b−, b+)∖{b}. This simply means that if we consider a small region (interval) around x = b, f(b) should be the maximum in that interval.Local Minima : A point x = a is a point of local minimum for f(x) if in the neighbourhood of a, i.e. in (a−,a+), (where can have arbitrarily small values), f(x) > f(a) for all x ∈ (a−,a+)∖{a}. This means that if we consider a small interval around x = a, f(a) should be the minimum in that interval.Given is that when an object is thrown upward with an initial velocity of v{0}, then its approximate height is given by this quadratic function -
S = - 4.9t² + [tex]$v_{o} ^{t}[/tex] + h
The approximate height is given by this quadratic function -
S = - 4.9t² + [tex]$v_{o} ^{t}[/tex] + h
{ 1 } - For the maximum height :
dS/dt = 0 ... Eq{ 1 }
dS/dt = -9.8t + [tex]$3.1^{t}[/tex] log(3.1) + 0 = 0
- 9.8t + [tex]$3.1^{t}[/tex] log(3.1) = 0
Refer to the graph attached. At t = 3.8 {possible value}, the function is 0.
So we get -
t = 3.8 s ... Eq{ 2 }
Maximum height achieved -
h{max} = - 9.8t + [tex]$3.1^{t}[/tex] log(3.1) + 15
h{max} = - 9.8 x 3.8 + [tex]$3.1^{3.8}[/tex] log(3.1) + 15
h{max} = - 37.24 + 73.65 x 0.50 + 15

How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
We need to Write the percent as a fraction in simplest form

A rectangular garden has a walkway around it. The area of the garden is 6(4.5x + 2.5). The combined area of the garden
and the walkway is 6.5(6x + 6). Find the area of the walkway around the garden as the sum of two terms.
Answers
Answer:
2w^2.
Step-by-step explanation:
Let "w" be the width of the walkway. Then, the length of the garden is 6.5(6x + 6) - 2w and the width of the garden is 6.5(6x + 6) - 2w.
The area of the garden is 6(4.5x + 2.5) = 6 * 4.5 * x + 6 * 2.5 = 27x + 15
The area of the garden and walkway is (6.5(6x + 6) - 2w)^2 = 27x + 15 + 2w^2
Equating the two expressions for the area of the garden:
27x + 15 = 27x + 15 + 2w^2
Thus, the area of the walkway is:

Given that, the size of a crowd that is 5 feet deep on both sides of the street along a 3-mile section of a parade route,
The number of people that can fit comfortably in a 6 feet by 6 feet area = 10
The ratio of the number of people per unit area = 10/(6 × 6) = 10/36
The area, A, occupied by the crowd = 5 feet × 3 mile × 2
3 miles = 15840 feet
∴ A = 5 feet × 15840 feet × 2 = 158400 ft²

Step-by-step explanation:
the midsegment EF of the trapezoid ABCD is half the sum of the parallel bases, that is
EF = [tex]\frac{AB+DC}{2}[/tex] ( substitute values )
x + 6 = [tex]\frac{2x-9+x+5}{2}[/tex]
x + 6 = [tex]\frac{3x-4}{2}[/tex] ( multiply both sides by 2 to clear the fraction )
2x + 12 = 3x - 4 ( subtract 3x from both sides )
- x + 12 = - 4 ( subtract 12 from both sides )
- x = - 16 ( multiply both sides by - 1 )
x = 16

Jamilas mom wants to make a size 10 dress and jacket. About how much yards of fabric does she need?
Answers
Answer:
[tex]2\frac{7}{8}[/tex]
Step-by-step explanation:
size 10 dress requires 2 1/4 yards of fabric while a jacket requires 1 5/8 yards so we add them
2 1/4+1 5/8
we make similar fractions and turn the denominator to 8
2 2/8+ 1 5/8
and now we can add the whole numbers first
2+1=3
now the fractions
2/8+5/8
7/8
final answer is 2 7/8
