What is the area of trapezoid ABCD? Enter your answer as a decimal or whole number in the box. Do not round at any steps.
Answers
The area of the trapezoid is given as 100. See the explanation for the same below.
What is a Trapezoid?A trapezoid is a quadrilateral with at least one set of parallel sides in American and Canadian English. A trapezoid is known as a trapezium in British and other varieties of English.
To find the length of each side of the trapezoid, you need to use the distance formula.
AB = (-1,5) and (3,2)
BC = (3,2) and (0,-2)
CD = (0,-2) and (-13, -11)
AD or DA = (-1,5) and(-13, -11)
Now, just use the distance formula for each line.
The Distance Formula is given as: d=√((x2 – x1)² + (y2 – y1)²).
Distance AB = √((3 – (-1))² + (2 – 5)²).
= √(4)² + (-3)²
= √(16+9)
= √25
AB = 5
lets us repeat this for the other section we will get:
Doing so gives us for all the points:
AB = 5
BC = 5
CD = 15.811388300842
DA or AD = 20
Note that:
The height is AD, the first base is AB and the second base is BC. We can plug the values for these sides into the trapezoid area formula, which is:
A = (base 1 + base 2) / 2 x height.
A = (5+5)/2 x 20
A = 5 x 20
A = 100.

Answers
Answer:
Gross Income = $ 43400
Adjusted Gross Income=$40500
Taxable Income = $33840
Step-by-step explanation:
given that-
Income paid to man
Wages = $41,500
Savings Interest = $1900
Tax Def Contribution=$2900
Deductions= $6660
personal exemption =$4050
Gross Income = Income paid to man = 41500 + 1900 = $ 43400
Adjusted Gross Income = Income - Tax Def Contribution = $43400-$2900=$40500
Taxable Income = AGI - Deductions = 40500 - 6660 = $33840

What is circumference of circle ?The perimeter of a circle is known as its circumference. It is the length of the circle's whole perimeter. The diameter of a circle and the constant are multiplied to get the circumference of the circle. This measurement of a circle's circumference is necessary for someone to cross a circular park or for a circle-shaped table to have a border. The units of the circumference are the same as the units of length and it is a linear value.
A circle is a closed round object whose border points are all equally spaced apart from the center, which is a fixed point.

Create a table of data for two different linear functions. The table should use the same values of x for both functions. Based on your table, will the graphs of these two functions intersect? Explain your answer
Answers
These two functions' graphs do indeed intersect:
Formula 1: F(X)=2X+5
The formula 2=H(X)=3X+2
INTERSECT=(3,11)
Describe function:a mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).Everywhere in mathematics are functions, which are essential for building physical connections in the sciences.
According to the given data:The first step is to generate two linear functions. I created the linear functions f(x)=2x+5 and h(x)=3x+2 (without a quadratic term). Then
You substitute a number for the x:
F(X)=2X+5 in Table 1 (H(X)=3X+2) Table 2
X=1——->Y=2+5=7 X=1------> Y=3·1+2=5
X=2---->

The slope of g(x) is [tex]\frac{-2}{5}[/tex] times the slope of f(x)
The x-intercept of f(x) is 8 more than the y-intercept of g(x)
As x approaches -∞, f(x) approaches ∞ and g(x) approaches -∞
Given,
f(x) = 10-5x
g(x) = -6+2x
The slope of f(x) = -5
The slope of g(x) = 2
Hence the slope of g(x) is [tex]\frac{-2}{5}[/tex] times slope of f(x)
For x-intercept assign zero value to f(x). Thus,
10-5x = 0
=> x = 2
So intercept of f(x) = 2
y-intercept of g(x) = -6
Hence x-intercept of f(x) is 8 more than y-intercept of g(x)
As x approaches -∞, f(x) = 10-(5 times (-∞)) = ∞
As x approaches -∞, g(x) = -6 + 2x = -6 + 2(-∞) = -∞

You have received a report of a mysterious illness that seems to turn the infected humans into mindless zombies has broken out in a major American city. Since the hungry zombies prey upon innocent people, the outbreak grows continuously at a rate of 12% per day. The outbreak begins with 8 people.
1. Write the formula that matches this scenario.
2. How many zombies will there be after 5 days?
3. How many days will it take for the zombie population to reach 3,700,00 (about the population of Los Angeles, CA)?
Answers
The solution to the questions are
The formula of the scenario is A = 8 * e^0.12tThe number of zombies after 5 days is 15The number of days is 39How to determine the formula?The general formula is given as
A = Pe^rt
In this case, we have
P = Initial number of people
r = rate
t = time
From the question, we have
P = 8
r = 12% = 0.12
So, we have
A = 8 * e^0.12t
The number of zombies after 5 daysThis means that t = 5
So, we have
A = 8 * e^(0.12 * 5)
Evaluate
A = 15
The number of days to reach 3,700,00This means that A = 3,700,00
So, we have
8 * e^0.12t = 3,700,00
Divide by 8
e^0.12t = 46250
Take the logarithm of both sides
0.12t = log(46250)
This gives
0.12t = 4.7
Divide
t = 39

a ball dropped vertically, falls d t seconds.
d is directly proportional to the sqaure of t.
the ball drop 80 meters in the 4 seconds
how far does the ball drop in the next 8 seconds
Answers
If the ball drops 80 meters in the 4 seconds, the time it takes the ball to drop in the next 8 seconds is; 720 meters
How to utilize constant of proportionality?
We are told that a ball dropped vertically falls a distance of d in t seconds and that d is directly proportional to the square of t. Thus;
D ∝ t²
Thus;
D = kt²
where d is the constant of proportionality.
We are given that D = 80 m when t = 4 seconds and as such we have;
80 = k*4²
k = 80/16
k = 5
Therefore, the equation of motion is;
D = 5t²
When t = 8 + 4 = 12 seconds, we have;
D = 5 * 12²
D = 5 * 144
D = 720 m
Therefore, the distance the ball drops in the next 8 seconds
= 720 - 80
= 640 m.
