Identify the area of the polygon that has vertices T(−3,1), S(−5,−4), A(−8,1), and N(−4,5)
Answer:
22.5
Step-by-step explanation:
The area of the polygon ABCD is 3/2 square units.
What is polygon?"It is two dimensional geometric figure having finite sides and vertices." A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.
here, we have,
we know that,
formula to find the area of the polygon:
"If polygon having vertices (x1, y1), ....(xn,yn) then the area of the polygon is,
A = 1/2 * | (x1y2 - x2y1) + ( x2y3 - x3y2) + .....+ (xny1 - ynx1)
This formula is also known as shoelace formula."
For given example,
the polygon has vertices T(−3,1), S(−5,−4), A(−8,1), and N(−4,5)
Consider given vertices of polygon as,
(x1, y1) = (−3,1)
(x2, y2)=(−5,−4)
(x3, y3)=(−8,1)
(x4, y4)=(−4,5)
Using the formula of area of the polygon the area of the polygon ABCD would be,
A = 1/2 * | (x1y2 - x2y1) + ( x2y3 - x3y2) + .....+ (x4y1 - y4x1)
so, solving we get,
A = 1/2 | 17 + 27 - 36 -11|
A = 3/2
Therefore, the area of the polygon ABCD is 3/2 square units.

Answer:
?
Step-by-step explanation:
54,675+33,548,000x^1+a^2=
get rid of ^1 cuz that doesn't change the value
a^2 can be written as 2a because a^2= a*a and 2a= a*a
54,675+33,548,000x+2a
54,675+33,548,000x= -2a-54675

He pays the money back after 4 years.
How much does he pay back in total?
9514 1404 393
Answer:
£8400
Step-by-step explanation:
The amount due after t years is ...
A = P(1 +rt)
A = £6000(1 + 0.10·4) = £6000·1.40
A = £8400

how do you solve −2x−4=3x+1 by graphing
Answer:
Step-by-step explanation:
You first have to simplify...
-2x-4=3x+1 (-1 both sides)
-2x-5=3x (+2x both sides)
-5=5x
-1=x
So graphing that would be a vertical line on -1.
A lemonade recipe calls for 1/4 cup of lemon juice for every cup of water what does x represent
Answer:
X represents the amount of cups of water
Answer:
x represents the number of cups of water.
Step-by-step explanation:
The recipe calls for ¹/₄ cups of lemon juice per 1 cup of water. This means the amount of lemon juice is dependent on the amount of water. In most functions, x is the independent variable and y is the dependent variable. Since the number of cups of lemon juice is dependent on the number of cups of water, the lemon juice represents y...
...and the water represents x.

When looking at a graph where do you find the roots of an equation?
Answer:
The points at which the graph crosses or touches x- axis, give the real roots of the function (or zeros of the function) represented by the graph. If the graph touches x-axis and turns back, then it would be a double root at that point.

Lincoln middle school plans to collect more than 2,000 cans of food in a food drive. So far, 668 cans have been collected. Write and inequality to find numbers of cams the school can collect on each of the final 7 days of the drive to meet this goal
Answer:
The answer is "[tex]\bold{668 + 7x > 2,000}[/tex]"
Step-by-step explanation:
7x = x is the cans obtained within 7 days 668 is the number of cans that are already obtained. Its number for goal cans is 2000. So, the equation is:
[tex]\to 7 x + 668 < 2000[/tex]
subtract and add the value 668:
[tex]- 668 \ \ \ \ \ -668[/tex]
[tex]\to 7x +0 < 1332[/tex]
Divide the value 7:
[tex]7 \ \ \ \ \ \ 7[/tex]
[tex]\to x < 190.30 \\\\OR\\\\\to x < 190\\\\[/tex]

Present age of the Victor as per given condition of the equation formed is equals to [tex]30[/tex] years.
What is equation?" Equation is defined as the relation between the variables and numbers using the sign of equality."
According to the question,
[tex]'x'[/tex] represents the present age of the Victor
[tex]'x+10'[/tex] represents the age of the Victor 10 years now
[tex]'x-10'[/tex] represents the age of the Victor 10 years ago
As per condition given equation we get,
[tex]x-10 = \frac{1}{2} (x+10)[/tex]
Simplify the equation to get the present age ,
[tex]2(x-10) = x+10\\ \\\implies 2x-20 = x+10\\\\\implies 2x-x = 20 +10\\\\\implies x =30[/tex]
Hence, present age of the Victor as per given condition of the equation formed is equals to [tex]30[/tex] years.

Another house is sold for £283,392
This is 1.6% less than the price paid for the house. What was the price paid?
Answer:
the price paid is £288,000
Step-by-step explanation:
The computation of the price paid is shown below:
Sale of the another house is £283,392
Since the another house would be 1.6% less than the price paid
So, the price paid would be
= £283,392 × 100 ÷ (100 - 1.6%)
= £283,392 × 100 ÷ 98.4
= £288,000
Hence, the price paid is £288,000

Answer:
There's no solution to this equation, when 2 equations have the same slope but different y-intercepts, they're parallel. This means they never intercept and there is NO solution and we can't solve for x.
The fish population in a local stream is decreasing at a rate of 3% per year. The original population was 48,000. Write an exponential function to model this situation. Then find the population after 7 years.
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Decrease rate (d)= 7%
Number of periods (n)= 7 years
Current population (PV)= 48,000
First, to calculate the future value, we need to use the following decrease exponential formula:
FV= PV*[(1+d)^-n]
After 7 years:
FV= 48,000*(1.07^-7)
FV= 29,892
The fish population after 7 years is 38783
An exponential decay is in the form:
y = abˣ;
where y, x are variables, a is the initial value of y and b is < 1
Let y represent the fish population after x years.
Since there is initially 48000 fish, hence a = 48000. Also it decrease at a rate of 3% per year. Hence b = 100% - 3% = 97% = 0.97
Therefore:
y = 48000(0.97)ˣ
After 7 years:
y = 48000(0.97)⁷ = 38783
Therefore the fish population after 7 years is 38783
