a certain radioactive isotope has leaked into a small stream. one hundred days after the leak 8% of the original amount of substance remained. Determine the half life of this radioactive isotope
Answers
Answer:
The half-life of a radioactive substance is the time it takes for half of the initial amount of the substance to decay. We can use the fact that 8% of the original amount remains after 100 days to determine the half-life of the isotope.
Let's assume that the initial amount of the substance is 1 unit (it could be any amount, but we're assuming 1 unit for simplicity). After one half-life, half of the original amount remains, or 0.5 units. After two half-lives, half of the remaining amount remains, or 0.25 units. After three half-lives, half of the remaining amount remains, or 0.125 units. We can see that the amount of substance remaining after each half-life is half of the previous amount.
We can use this information to set up the following equation:
0.08 = (1/2)^n
where n is the number of half-lives that have elapsed. We want to solve for n.
Taking the logarithm of both sides, we get:
log(0.08) = n*log(1/2)
Solving for n, we get:
n = log(0.08) / log(1/2) = 3.42
So the number of half-lives that have elapsed is approximately 3.42. Since we know that 100 days is the time for three half-lives (from the previous calculation), we can find the half-life by dividing 100 days by 3.42:
Half-life = 100 days / 3.42 = 29.2 days (rounded to one decimal place)
Therefore, the half-life of the radioactive isotope that leaked into the stream is approximately 29.2 days.

Okay so, if he is getting a console for $17.50, then you first want to do is subtract that from the total amount that he has which is $49.
49 - 17.50 = $31.50
Now each game costs $5.25
You can either just keep adding 5.25 by itself until you get to 31.50, or you can just divide 31.50 by 5.25, but I am going to just multiply then by certain numbers until I get the result.
5.25 * 5 = 26.25 so we know he can buy more than 5.
5.25 * 6 = 31.50
He can buy 6 games!

Answer Choices
Answers
Answer:
D.
Step-by-step explanation:
If She earns 80$ PER day + 8$ per phone sold and makes AT LEAST 176$ on Tuesday, You need to figure out how many phones she has sold by Tuesday.
Okay so now you need to set up your problem.
8x + 80 ≥ 176
Take away the 80, then take 80 from 176.
176 - 80 = 96
96 ÷ 8

Four people- Rob, Sonya, Jack, and Ang- enter their names into a drawing. The winner receives either a t-shirt or a mug, and which prize they receive is randomly selected. What is the probability that either Ang wins and is given a mug, or Jack wins (and is given either prize?) Write the answer as a precent.
Answers
Explanation:
The probability that Ang wins is 1/4 since he's one person out of the four total. This assumes each person has an equal chance at winning.
Once Ang wins, the chances of getting a mug are 1/2.
So the probability of Ang winning and getting a mug is (1/4)*(1/2) = 1/8
Meanwhile, the probability of Jack winning and getting either prize is 1/4, which we'll add to the previous result to get
1/8 + 1/4 = 1/8 + 2/8 = (1+2)/8 = 3/8
Then convert this to a percentage
3/8 = 0.375 = 37.5%

Given the unit circle what is the value of x
Answers
Hello there. To solve this question, we'll have to remember some properties about the unit circle.
Given the unit circle:
Notice we have a right triangle with opening angle theta and hypotenuse equals 1.
Therefore all the points in this unit circle have coordinates (cos(Θ), sin(Θ)).
To find the value of x, we first have to know that it is a point from the third quadrant, so the angle is between pi and 3pi/2.
In this case, cos is negative and so do sin.
We just have to make:
\(\sin (\theta)=-\frac{\sqrt[]{2}}{2}\)For an angle theta between pi and 3pi/2.
We know that sin(pi/4) = sqrt2/2. Also, from the identity sin(x + pi) = -sin(x), we have that:
sin(pi/4 + pi) = sin(5pi/4) = -sin(pi/4) = -sqrt2/2.
Therefore we say the angle theta is 5pi/4.
Taking its cosine, we have:
\(x=\cos \mleft(\frac{5\pi}{4}\mright)=-\cos \mleft(\frac{\pi}{4}\mright)=-\frac{\sqrt[]{2}}{2}\)Thus we have that the expressions between brackets are:

A rectangular park had a dirt path across its diagonal that was yards long. The diagonal and the long side of the park formed an angle that measured . A person walked along the sidewalks outside the park, from the start to the end of the path, as shown by the arrows. The diagonal dirt path that cuts across the rectangular park and the sidewalks outside the park form a right triangle. The dirt path is the hypotenuse and it is labeled 100 yards. The start of the sidewalk is adjacent to the 30-degree angle, and it is labeled X. The end of the path is opposite the 30-degree angle, and it is labeled Y. Which expression shows the distance that he walked?
Answers
Trigonometry functions are functions that relate two sides of a given triangle with one of its included angles.
The expression that shows the distance that he walked = x + y + 100
= 87 + 50 + 100
= 237 yards
Trigonometry functions are functions that relate two sides of a given triangle with one of its included angles. The required function may be a sine function, a cosine function, or a tangent function.
Such that;
Sin θ = \(\frac{Opposite}{Hypotenuse}\)Cos θ = \(\frac{Adjacent}{Hypotenuse}\)Tan θ = \(\frac{Opposite}{Adjacent}\)The given question can be solved by applying the appropriate trigonometric function.
So that to determine the value of x, we have:
Cos θ = \(\frac{Adjacent}{Hypotenuse}\)
Cos 30 = \(\frac{x}{100}\)
⇒ x = 100 cos 30
= 100 x 0.866
x = 86.60
Thus, the start of the sidewalk is approximately 87 yards.
To determine the value of sidewalk y, we have:
Sin θ = \(\frac{Opposite}{Hypotenuse}\)
Sin 30 = \(\frac{y}{100}\)
⇒ y = 100 x Sin 30
= 100 x 0.5
y = 50
Thus the sidewalk which represents the end of the path is 50 yards.
Therefore, the total distance that he walked = 100 + 87 + 50
= 237 yards
The expression that shows the distance that he walked = x + y + 100
= 87 + 50 + 100
= 237 yards
