Name Each of the vertices on the quadrilateral
The names of the vertices (or corners) are the letters next to them. However you may need to write the plot points, so you would look at the left side or the y axis and count where the dot is as a number. Lets say its D. D is 4 on the y axis. Then you would go straight down to find the x axis. It is right over three. than you would write it with the x axis ALWAYS first. So D is (3,4).

Answer:
$15.78
Step-by-step explanation:
I) Remove tax:
$50.18 - $2.84 = $47.34
II) Construct an equation to find the cost of each shirt:
47.34 = 3s
III) Solve:
Divide each side by 3:
15.78 = s
Each shirt costed $15.78
Answer:
15.78

The radioactive isotope of lead, Pb-209, decays at a rate proportional to the amount present at time t and has a half-life of 3.3 hours. If 1 gram of this isotope is present initially, how long will it take for 90% of the lead to decay? (Round your answer to two decimal places.)
Answer:
It will take 10.96 hours for 90% of the lead to decay.
Step-by-step explanation:
The radioactive isotope of lead, Pb-209, decays at a rate proportional to the amount present at time t
This means that the amount can be modeled by the following function:
[tex]A(t) = A(0)e^{-rt}[/tex]
In which A(0) is the initial amount and r is the decay rate.
Has a half-life of 3.3 hours.
This means that [tex]A(3.3) = 0.5A(0)[/tex]. We use this to find r.
[tex]A(t) = A(0)e^{-rt}[/tex]
[tex]0.5A(0) = A(0)e^{-3.3r}[/tex]
[tex]e^{-3.3r} = 0.5[/tex]
[tex]\ln{e^{-3.3r}} = \ln{0.5}[/tex]
[tex]-3.3r = \ln{0.5}[/tex]
[tex]r = - \frac{\ln{0.5}}{3.3}[/tex]
[tex]r = 0.21[/tex]
So
[tex]A(t) = A(0)e^{-0.21t}[/tex]
How long will it take for 90% of the lead to decay?
This is t for which [tex]A(t) = 0.1A(0)[/tex], that is, 100 - 90 = 10% of the initial amount.
[tex]A(t) = A(0)e^{-rt}[/tex]
[tex]0.1A(0) = A(0)e^{-0.21t}[/tex]
[tex]e^{-0.21t} = 0.1[/tex]
[tex]\ln{e^{-0.21t}} = \ln{0.1}[/tex]
[tex]-0.21t = \ln{0.1}[/tex]
[tex]t = -\frac{\ln{0.1}}{0.21}[/tex]
[tex]t = 10.96[/tex]
It will take 10.96 hours for 90% of the lead to decay.

Margo’s dog, named Todd, weighed 120 pounds last year. She now weighs 180 pounds. What is the percent of change
Answer:
50%
Step-by-step explanation:
the increase is 60 so divide that by the original number; 60/120=0.5
now we have to change the decimal to a percent. multiply by 100 to do that and we get 50%.
Answer:
Step-by-step explanation:
[tex]\Delta \%=100\left(\frac{final-initial}{initial}\right)\\ \\ \Delta \%=100\left(\frac{180-120}{120}\right)\\ \\ \Delta \%=100\left(\frac{60}{120}\right)=50\% [/tex]

Answer:
Step-by-step explanation:
Standard form of a circle is given by,
(x - a)² + (y - b)² = r²
Here, (a, b) is the center and 'r' is the radius of the circle.
For a circle having center (8, -4) and radius r = 1
Equation of the circle will be,
(x - 8)² + (y + 4)² = 1²
(x - 8)² + (y + 4)² = 1
Option (1) is the answer.
Question (2)
Circle with the center (-1, 0) and a point (2, -4) on it,
Radius of the circle = Distance between the center and the given point on circumference
= [tex]\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
= [tex]\sqrt{(-1-2)^2+(0+4)^2}[/tex]
= [tex]\sqrt{9+16}[/tex]
= 5
Therefore, equation of the circle will be,
(x + 1)² + (y - 0)² = 5²
(x + 1)² + y² = 25

If twice a number added to 3 is divided by the number plus 6, the result is three halves. Find the number.
Answer:
3/2
Step-by-step explanation:
Let x be the unknown number.
If twice a number added to 3: 2x+3
is divided by the number plus 3: (2x+3)/3
the result is three halves: (2x+3)/3 = 3/2
(2x+3)/3 = 3/2
Multiply both sides by 3:
2x + 3 = 9/2
Subtract 3 from both sides:
2x = 9/2 - 3 = 9/2 - 6/2 = 3/2
Divide both sides by 2:
x = 3/4
Check:
(2x+3)/3 = 3/2
(2*(3/4)+3)/3 = 3/2
(6/4 + 3)/3 = 3/2
(18/4)/3 = 3/2
6/4 = 3/2
3/2 = 3/2
Check!
