The circle described by the equation (x - 3)² + (y + 4)² = 9 is translated 5 units to the left and one unit up.
At what point is the center of the image circle located?
A) (-8,5)
B) (8, -5)
C) (2, -3)
D) (-2, -3)
Answers
Answer:
New coordinates are (-2, -3)
Step-by-step explanation:
First we need the centre coordiates. In (x - a)² + ( y - b)² = r² , a is the x coordinate for the circle centre and b is the y coordinate for the circle centre, so this means the coordinate of the circle centre is:
(3 , -4)
If moving to the left 5 spaces, then 5 has to be subtracted from the x coordinate:
3 - 5 = -2
Now moving one up you add one to the y coordinate:
-4 + 1 = -3
So the new coordinates are (-2, -3)

Assume you have such a watch. if a minimum of 18.0% of the original tritium is needed to read the dial in dark places, for how many years could you read the time at night? assume first-order kinetics.
Answers
The amount of substance left of a radioactive substance with half life of [tex]t_{ \frac{1}{2} }[/tex] after t years is given by
[tex]N(t)=N_0\left(\frac{1}{2} \right)^{ \frac{t}{t_{\frac{1}{2}} }[/tex]
Therefore, the number of years it will take for 18% of the original tritinum to remain is given by
[tex]18 \% = 100 \% \left(\frac{1}{2} \right)^{ \frac{t}{12.3}} \\ \\ \Rightarrow\left(\frac{1}{2} \right)^{ \frac{t}{12.3}} =0.18 \\ \\ \Rightarrow\frac{t}{12.3}\ln\left(\frac{1}{2} \right)=\ln0.18 \\ \\ \Rightarrow\frac{t}{12.3}= \frac{\ln0.18}{\ln\left(\frac{1}{2} \right)} = \frac{-1.715}{-0.6931} =2.474\\ \\ \Rightarrow t=2.474(12.3)=30.4[/tex]
Therefore, the number of years that the time could be read at night is 30.4 years.
Final answer:
You could read the time on a tritium-based watch in dark places for approximately 34.87 years before the tritium decays below 18% of its original amount, necessitating this calculation using first-order kinetics and the half-life of tritium (12.32 years).
Explanation:
To calculate how many years you could read the time at night with a watch containing tritium, we need to understand first-order kinetics and the half-life of tritium.
Tritium has a half-life of 12.32 years, meaning after 12.32 years, half of the original tritium remains.
The question specifies that a minimum of 18% of the original tritium is needed for readability in dark places.
To find the number of years you could read the time, we use the formula for first-order decay:
[tex]N = N_0(1/2)^{(t/T)[/tex],
where N is the final amount of substance left, N_0 is the initial amount of substance, t is the time in years, and T is the half-life (12.32 years in this case).
We rearrange the formula to solve for t:
t = T*log(N/N_0)/log(1/2).
Plugging in the values, assuming N/N_0 = 0.18 (18%), and T = 12.32 years, we get:
t = 12.32*log(0.18)/log(1/2) ≈ 34.87 years.
Therefore, you could read the time on a tritium-based watch in dark places for approximately 34.87 years before the tritium decays below the level necessary for visibility.

Dane is 10 times Brian's age. The difference in their age is 27, how old is Brian
Answers
Hope this helps!
Answer:
Brain is 3 years old.
Step-by-step explanation:
Let B represent Brain's age and D represent Dane's age.
We have been given that Dane is 10 times Brian's age. We can represent this information in an equation as:
[tex]D=10B...(1)[/tex]
We are also told that the difference in their age is 27. We can represent this information in an equation as:
[tex]D-B=27...(2)[/tex]
Upon substituting equation (1) i equation (2), we will get:
[tex]10B-B=27[/tex]
[tex]9B=27[/tex]
[tex]\frac{9B}{9}=\frac{27}{9}[/tex]
[tex]B=3[/tex]
Therefore, Brain is 3 years old.

If a line of one billion people standing shoulder to shoulder stretches 346,439 miles long, what is the average shoulder width, in feet, of the people in the line?
Answers
Given a line of one billion people extending for 346,439 miles, the average shoulder width of a person in the line is approximately 1.83 feet.
Explanation:To find the average shoulder width of the people in the line, we need to convert the total miles into feet, since the result wanted is in feet. There are 5,280 feet in one mile. So the total length in feet would be 346,439 miles * 5,280 feet/mile = 1,829,029,920 feet. Now, if there are 1 billion people in this line, then the average width of a person's shoulders would be the total length divided by the total number of people. Hence, the average shoulder width = 1,829,029,920 feet / 1,000,000,000 people = approximately 1.83 feet.

Since the car travels 476 miles with 14 gallons of gas, then 476/14 = 34, so the car can travel 34 miles per gallon.
The distance is 34 times the number of gallons
d = 34g
Now you are given 578 miles, and you need to find the gallons.
578 = 34g
Solve for g by dividing both sides by 34.
g = 17
He needs 17 gallons.
