LA
c. Find the interest if it is compounded continuously.
$
d. What is the difference in total interest if computed using simple interest or if compounded
continuously?
a) The interest if computed using simple interest for 3 years at 2% is $120.
c) The interest when compounded continuously for 3 years at 2% is $123.67.
d) The difference in total interest between using simple interest and continuously compounding is $3.67.
What is simple interest?Simple interest is a straightforward way of computing the interest paid on a loan.
The formula for calculating simple interest is P x R x T, where P = Principal, R = Rate, and T = Time.
The formula for continuous compounding first computes the future value (FV) from which the present value (PV) is deducted, as follows:
FV = PV x e ^ (i x t), where e is the mathematical constant approximated as 2.7183.
Principal = $2,000
Rate of interest = 2%
Period = 3 years
Simple Interest = $120 ($2,000 x 2% x 3)
Continuous compounding = FV - PV
FV = $2,000 x 2.7183 ^ (0.02 x 3)
= $2,000 x 1.06183697
= $2,123.67
Interest = $123.67 ($2,123.67 - $2,000)
The difference in total interest = $3.67 ($123.67 - $120)
Thus, continuous compounding produces a difference in the interest of $3.67 when compared to simple interest.

A.a² + 3b-2
B. 5a² + 3b + 6a
C.9a² + 3b + 6a
D. 11a²+ 3b +6
Answer:
B. 5a² + 3b + 6a
Step-By-Step Explanation:
First, see what has like terms. 7a² and -2a² both have the exponent 2 and the letter a, so you can combine those to get 5a². 3b and 6a cannot be combined because they have a different letter. So, 5a² + 3b + 6a is your answer.
Find the equation (in terms of x ) of the line through the points (-2,-2) and (3,-1)
Answer:
Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.
First find the gradient.
Formula of gradient is given as (y2-y1)÷(x2-x1) or (y1-y2)÷(x1-x2)
Gradient = (-1-(-2))÷(3-(-2))
= (-1+2)÷(3+2)
= 1/5
Equation is y = 1/5 + c
Substitute either one of the points into the equation to find c.
-2 = 1/5(-2) + c
c = -8/5
Hence equation of the line is y = 1/5x - 8/5

Which of the following is an equivalent expression of 15x2 +12x + 8?
27x3 + 8
15x2(12x + 8)
12x + 15x2 + 8
8(15x2 + 12x)
The option that is an equivalent expression of 15x² +12x + 8 is C. 12x + 15x² + 8.
What is an equivalent expression?Expressions that are equivalent do the same thing even when they have distinct appearances. When we enter the same values for the variable, two algebraic expressions that are equivalent have the same values.
If two systems of equations have the same solution, they are equivalents. In algebra, 2(2x - 3y + 6) is equal to 4x -6y + 12 as an example of an equivalent expression.
In this case, it should be noted that 15x² +12x + 8 is the same as 12x + 15x² + 8. Therefore, the correct option is C.

A rectangular plot of ground is 10 m longer than it is wide. It’s area is 10,000 square meters.
Based on the fact that the rectangular plot has a length that is 10 m longer than the width, the equation that will help to find area of the rectangular plot of land is 10x + x² = 10,000
How to find the area of the plot of land?To find the area of the plot of land is the same as finding the area of a rectangle which is:
Area of a rectangle = Length x Width
Assuming the width of the rectangular plot of ground is x, then the length would be:
= 10m + x
= 10 + x
The area of the rectangular plot of ground can therefore be found by the formula:
Area of a rectangle = Length x Width
10,000 square meters = (10 + x) × x
10,000 square meters = 10x + x²
10x + x² = 10,000
In conclusion, an equation that can help you to find the dimensions of the plot of ground is 10x + x² = 10,000.

How many times larger is 2 x 10^12 than 5 × 10^6
Answer:
[tex]4*10^5[/tex]
Step-by-step explanation:
So whenever sometimes says "how many is x larger than y", it just means what is x divided by y. For example 4 is 2 times as much as 2 because 4/2 = 2
With this being said we can simply divide two numbers
[tex]\frac{2*10^{12}}{5*10^6}[/tex]
Whenever you divide scientific notation you simply divide the two coefficients and subtract the exponents from the base 10
So: [tex]\frac{2*10^{12}}{5*10^6} =\frac{2}{5} * 10^{12-6}[/tex]
This gives you a result of: [tex]0.4 * 10^6[/tex]
Since we want the coefficient to be: [tex]1\le c < 10[/tex] we can take one of the 10s from the base, since 10^6 is just 6 tens being multiplied by each other and we can "borrow" one of them to get: [tex]0.4*10^6=0.4*10*10^5[/tex] which simplifies to: [tex]4*10^5[/tex]

4. (-31, -56): 2x - y = -6; x - 305/3 = 2y.
How to Solve a System of Equations?We can solve a system using the substitution method by finding the value of one of the variables, followed by substitution.
1. x - y = 25 -- eqn. 1
2x + 3y = 180 -- eqn. 2
Rewrite eqn. 1:
x = 25 + y
Substitute x = 25 + y into eqn. 2:
2(25 + y) + 3y = 180
50 + 2y + 3y = 180
5y = 180 - 50
5y = 130
y = 26
Substitute y = 26 into eqn. 1:
x - 26 = 25
x = 25 + 26
x = 51
The solution is: (51, 26).
2. x - y = 19 -- eqn. 1
-2x + y/6 = 28 -- eqn. 2
Rewrite eqn. 1:
x - y = 19
x = 19 + y
Substitute x = 19 + y into eqn. 2:
-2(19 + y) + y/6 = 28
-38 - 2y + y/6 = 28
-11y/6 = 28 + 38
-11y/6 = 66
-11y/6 (-6/11)= 66(-6/11)
y = -36
Substitute y = 36 into eqn. 1:
x - y = 19
x - (-36) = 19
x + 36 = 19
x = 19 - 36
x = -17
The solution is: (-17, -36).
3. 2x - 3y = -5 -- eqn. 1
x + y/11 = 50 -- eqn. 2
x + y/11 = 50
x = 50 - y/11
Substitute x = 50 - y/11 into eqn. 1
2(50 - y/11) - 3y = -5
100 - 2y/11 - 3y = -5
-35y/11 = -5 - 100
-35y/11 = -105
-35y/11(-11/35) = -105(-11/35) (multiplication property)
y = 33
Substitute y = 33 into eqn. 2:
x + 33/11 = 50
x + 3 = 50
x + 3 - 3 = 50 - 3
x = 47
The solution is (47, 33).

Use the value 3.14 for π. Round your answer to the nearest tenth. Do not round any intermediate steps.
If a tire on the snowplow with a diameter of 3.2 ft turns 47 times then, the length of the street is 472.3 feet.
To clear a street the city workers use a snowplow. The diameter of the tire of the snowplow is 3.2 ft.
The tire has to turn 47 times to cover the total length of the street.
Now, we know that the circumference of a circle is given as:
C = 2πr where r is the radius of the circle. And the radius of a circle is half of its diameter.
Therefore, the circumference of the circle can be written as:
C = πD where D is the diameter of the circle.
Now, to calculate the total length of the street we will find the product of the circumference and the number of times the tire has to turn to cover the street.
Therefore,
Length of the street, L = nC
L = nπD
L = 47 × 3.14 × 3.2 ft
L = 472.256 ft
L = 472.3 ft
Hence, the length of the street is 472.3 feet.

Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 4 ) and (x₂, y₂ ) = (- 7, 9 )
m = [tex]\frac{9-4}{-7-(-2)}[/tex] = [tex]\frac{5}{-7+2}[/tex] = [tex]\frac{5}{-5}[/tex] = - 1 , then
