The coordinates of parallelogram in geometry ABCD are A( 0,2 ) ( 2,2 ) ( 1,1 ) ( -1, 1)
What is geometry?The area of mathematics known as geometry is concerned with the dimensions, sizes, angles, and shapes of various objects that we encounter every day.
Solution:
All the angles of a parallelogram are not equal. Only the opposite angles of a parallelogram are equal and the consecutive (adjacent) angles of a parallelogram are always supplementary.
Hence using this property coordinates of parallelogram in geometry ABCD are A( 0,2 ) ( 2,2 ) ( 1,1 ) ( -1, 1)

PLEASE HELP I REALY NEED THIS NOW How much simple interest is earned on an investment of $800 with a rate of 6.1% over 7 years?
A. $341.60
B. $410.87
C. $3,416.00
D. $4,108.70
Answers
The amount of simple interest is (a) $341.60
How to determine the amount of simple interest?From the question, we have the following parameters that can be used in our computation:
Principal, P = $800
Rate, r = 6.1 %
Time = 7 years
The simple interest on the investment is calculated as
I = PRT
Substitute the known values in the above equation, so, we have the following representation
I = 800 * 6.1% * 7
Express 6.1% as decimal
So, we have the following representation
I = 800 * 0.061 * 7
Evaluate the products
I = 341.6
Hence, the amount is (a) $341.6

Answers
After solving the given equation for c, we know that the value of c is (A) -56.
What are equations?Equivalent systems refer to sets of equations with the same solution.
We can create an analogous system from a system of two equations by replacing one equation with the total of the two equations or by replacing an equation with a multiple of itself.
So, we have the equation:
-5 = 9+(c/4)
Now, solve for the subject c as follows:
-5 = 9+(c/4)
-5 -9 = (c/4)
-14 = c/4
c = -14*4

Suppoe that the concentration of a bacterial ample i 100,000 bacteria per millimeter. If the concentration double every three hour how long will it take for the concentration to reach 350,000 material per millimeter?
Answers
The time t = 3.4209 will it take for the concentration to reach 350,000 material per millimeter.
How do you calculate hours and minutes?In an hour, there are 60 minutes. Divide the number of minutes by 60 to convert it to hours. For instance, 120/60=2 means that 2 hours are equal to 120 minutes.
What is millimeter?The millimeter, abbreviated mm in the International System of Units (SI), or millimeter, abbreviated mm in the American spelling, is a unit of length that is one thousandth of a metre long, the SI base unit of length. As a result, a metre is made up of 1000 millimeters.
We are going to use formula
y = a * e ^ (b * t)
a and b are constants and t is for time.
Initially there are 100,000 bacteria, so;
100000 = a * e ^ (b * 0)
100000 = a * 1
a = 100000
given condition is that the concentration doubles every 3 hours so
300000 = a * e ^ (b * 3)
As a equals to 100,000
e ^ (b * 3) = 3
b * 3 = ln 3
b = (ln 3) / 3
b = 0.3662
now we have to find value of the time when concentration of bacteria reaches to 350,000:
350000 = 100000 * (e ^ 0.3662 * t)
3.5 = e ^ 0.3662* t
ln 3.5 = 0.3662* t
t = 1.2527 / 0.3662
t = 3.4209
That is the required value of time

Answers
The amount that Josephine will be paid is $644.30.
How much was Josephine paid?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred.
In this situation, Josephine earns a salary of $560.00 per week, plus a commission of 10% on all sales and she sold $843 worth of goods.

Answer:
y = -8x + 23
Step-by-step explanation:
8y=x-16
we need to turn this into slope-intercept form by dividing 8 on both sides
y = x/8 - 2
to make a line perpendicular from another, we must make sure the slope is the negative reciprocal of the original line.
Right now, it's the same as the original. To make it a negative reciprocal, switch the places of the denominator and numerator and flip the signs
-8x is the negative reciprocal of x/8
Does it go through (4,-9)? No.
To make sure it goes through 4,-9, we change it's y-intercept.
Plug in the coordinate given (4,-9) in the y = -8x + b ( we removed -2 since it's not the right answer.
y = -8x + b
(-9) = -8(4) + b
-9 = -32 + b
-9 +32= -32 + b +32
23 = b
plug in b and we get our answer
y = -8x + 23

What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
The equation of the lines will be,
y = mx + c
y = 3x + c
-1 = 4 x 3 + c
c = -13
y = 3x - 13
y = mx + c
y = -4x + c
0 = -4 x -8 + c
c = -24
y = -x -24
y = mx + c
y = 1/6x + c
-10 = -1 + c
c = -9
y = -1/6x - 9
Therefore, the equation of the lines is,y = 3x - 13 y = -4x - 24 and y = -1/6x - 9.

What is the equation for the graph shown?
Answers
The linear equation on the graph shown is:
y = (2/3)*x + 4
What is the equation on the graph?
We can see that we have a linear equation on the graph, remember that a general linear equation is:
y = a*x + b
Where a is the slope and b is the y-intercept.
On the graph, we can see that the line intercepts the y-axis at y = 4, then the y-intercept is b = 4
y = a*x + 4
To find the slope we can use another point on the line, for example, we can see that (-6, 0) is also on the line, replacing these values in the linear equation above we will get:
0 = a*-6 + 4
6a = 4
a = 4/6 = 2/3
Thus, the line is:
y = (2/3)*x + 4
