The area of the polygon is approximately 24.497 square units.
How to determine the area of a polygon
In accordance with the statement, we have a polygon with three vertices set on Cartesian plane, that is, a triangle. We need to find the side lengths first and later to calculate the area by Heron's formula. First, determine the lengths of each line segment by Pythagorean theorem:
JK = √[[4 - (- 3)]² + (4 - 4)²]
JK = 7
KL = √[(3 - 4)² + (- 3 - 4)²]
KL = √[(- 1)² + (- 7)²]
KL = 5√2
JL = √[[3 - (- 3)]² + (- 3 - 4)²]
JL = √85
Second, calculate the area of the triangle:
s = (JK + KL + JL) / 2
s = (7 + 5√2 + √85) / 2
s ≈ 11.645
A = √[s · (s - JK) · (s - KL) · (s - JL)]
A = √[11.645 · (11.645 - 7) · (11.645 - 5√2) · (11.645 - √85)]
A ≈ 24.497
The area of the polygon is approximately 24.497 square units.

How to determine the volumeThe formula for volume of a rectangle is expressed as;
Volume = length × width × height
From the information given, we have the following parameters;
Length = 25 yardsWidth = 14 yardsHeight = 5 yardsSubstitute the values into the formula
Volume = 25 × 14 × 5
Find the product
Volume = 1750 cubic yards
Covertoing cubic yard to cubic feet
I cubic yard = 27 cubic foot
1750 yards = x
x = 27 × 1750
x = 47, 250 cubic feet

The vehicle will get speed of approximately 15 mph and -210 mph.
What is speed?Science's most important concept is measurement. Many measurable quantities are measured in fundamental or base units. One such measurable quantity is speed, which is defined as the ratio of an object's distance travelled to the time required to travel that distance. Let us learn about speed in depth during this session.
The ratio of distance to time taken to cover a distance is used to calculate speed. Because it only has one direction and no magnitude, speed is a scalar quantity.
Given the equation for gas mileage = 0.02x² + 3.9x - 43 where x means speed
We have been asked to find x if gas mileage = 20 that is
0.02x² + 3.9x - 43 = 20
Lets simplify
⇒ 0.02x² + 3.9x - 43 = 20
⇒ x² /50 + 39x/10 - 63 = 0
⇒ x²/ 50 + 195x/50 - 3150 = 0
⇒ 1/50 (x + 195x - 3150 ) = 0
⇒ 1/50 (x + 210x - 15 x - 3150 ) = 0
⇒ 1/50 (x (x+210) −15 (x+210)) = 0
⇒ 1/50 (x−15)(x+210) = 0
⇒ (x−15)(x+210) = 0 × 50
⇒ (x − 15)(x + 210) = 0
⇒ x = 15, x = -210
So, try using 15 mph and -210 mph, that might work.

27. You are driving on the interstate with your cruise control on at a constant speed of 64 miles per hour.
Use the number lines below to determine how long it will take to drive to the next rest sop that is 16
miles away (see textbook, page 20). Explain the thinking you used to determine your answer.
Answers
The car will take 15 minutes to drive to the next stop which is 16 miles away.
As per the question statement, we are supposed to find the time taken by the car to drive to the next stop which is 16 miles away if it is driving on the interstate with cruise control on at a constant speed of 64 miles per hour.
Before solving the question, we need to know the concept of relation between time, distance and speed, which states that
[tex]speed=\frac{distance}{time}[/tex]
In the question [tex]speed = 64 mph\\distance = 16 miles\\time taken = t[/tex]
Substituting values in the formula above,
[tex]64=\frac{16}{t} \\t=\frac{16}{64} \\t=0.25 hours =0.25 *60\\t=15 minutes[/tex]
Hence the time taken by car to drive to the next stop which is 16 miles away is 15 minutes or [tex]\frac{1}{4}[/tex] hours.

What is the 19th term of the sequence:
gn=gn−1⋅(−12) if g17=162
the sixth term is ______
Answers
This is an arithmetic sequence
The nth term of an arithmetic sequence is Tn = a + (n-1)d
a is the first term.
n is the number of terms
d is the common difference
Given that 19th term of the sequence is:
gn=gn−1⋅(−12) if g17=162
Suppose a=12
Then,
The 17th term g17=a+(n-1)d
= 12+(17-1)d
'n' means number of terms
12+(17-1)d=162 because g17=162
12+16d=162
16d=162-12
Subtract the values,
We can write,
16d=150
d=150/16
Divide the values,
We can write,
d=25
To get the sixth term g6
g6=12+(6-1)d
=12+5d
Replace with d value in above equation,
Then, g6=12+5(25)
g6=12+125
g6=137
So, the sixth term is g6=137.

Your answer should be 90 degrees for angle one. For angle two, 58 and angle three 32.
Step-by-step explanation:
This is because they are supplementary angles! I hope this helps. Xx
Answer: ∠1 = 90°
Step-by-step explanation:
∠1 = ∠4
∠2 = ∠5
∠3 = ∠6
reason = vertically opposite angle
∠1 = 90°
∠2 = 58°
∠3 = 32°
checking :
total angles = 360°
360° = ∠1 + ∠2 + ∠3 + ∠4 + ∠5 + ∠6
360° = 90° + 58° + 32° + 90° + 58° + 32°
360° = 360°

Suppose you had d dollars in your bank account. You spent $14 but have at least $48 left. How much money did you have initially? Write and solve an inequality that represents this situation.
Answers
The inequality that represents this situation is d - 14 >= 48 and the solution is d >= 62
How to write and solve an inequality that represents this situation.The given parameters are:
Initial amount = d
Spent = 14
Amount left = at least 48
The above means that
d - 14 = at least 48
at least 48 means greater than or equal to 48
So, we have
d - 14 >= 48
Add 14 to both sides
d >= 62
Hence, the inequality that represents this situation is d - 14 >= 48 and the solution is d >= 62
