If 16g if a radioactive substance are present initially and 5yr later only 8g remain how much substance will be present after 9yr
9514 1404 393
Answer:
4.59 g
Step-by-step explanation:
The half-life is given as 5 years, so the amount remaining after 9 years will be ...
remaining = initial × (1/2)^(t/(half-life))
remaining = (16 g)×(1/2)^(9/5) ≈ 4.59 g
About 4.59 g of the substance will remain after 9 years.

Answer:
7-5 => 2-7+5 => -2-7-5 => -127-(-5) => 12Step-by-step explanation:
Lets solve the expressions one by one
1. 7-5
we can see that it is simple subtraction. A smaller number is being subtracted from a large number.
So the answer is 2
2. -7+5
There are two numbers with different signs. When there is a number with plus and a number with minus both quantities are subtracted but the larger quantity determines the sign of the answer.
In this case, 7 is larger and has negative sign, the answer will be -2
3. -7-5
When there are two numbers with minus sign they are added but the answer has the minus sign with it.
So the answer will be: -12
4. 7-(-5)
When minus is multiplied with minus it converts to positive
So
[tex]= 7-(-5) = 7+5 = 12[/tex]
Hence,
7-5 => 2-7+5 => -2-7-5 => -127-(-5) => 12solve. -1/2 + (3/4 x 4/9) =
A. 1/9
B. -1/5
C. 5/6
D -1/6
Answer:
D, -1/6
Step-by-step explanation:
-1/2+(3/4*4/9)
Multiply equation inside the parentheses
3/4*4/9=12/36=1/3
Substitute 1/3 into original equation
-1/2+1/3=1/3-1/2
Make denominators the same
2/6-3/6
Simplify
-1/6, D

What is the focus of the parabola? y=−1/4x^2 −2x − 2
Answer:
Step-by-step explanation:
This is a doozy. You have to know A LOT about parabolas to get to this answer. First and foremost, we will have to complete the square on the x terms and get everything else on the other side of the equals sign with the intention of putting this into standard form which looks like this:
[tex]-4p(y-k)=(x-h)^2[/tex]
The negative is because the parabola is upside down. We begin breaking it down by multiplying everything by -4 to get:
[tex]-4y=x^2+8x+8[/tex] and subtract that 8 from both sides to get:
[tex]-4y-8=x^2+8x[/tex]. Now we'll complete the square on the x terms by taking half the linear term, squaring it, and then adding it to both sides. Our linear term (the number with the x stuck to it) is 8. Half of 8 is 4 ad 4 squared is 16. So we add 16 to both sides to get:
[tex]-4y-8+16=(x^2+8x+16)[/tex]
The right side will simplify into a perfect square binomial and the left side we will just combine like terms to get:
[tex]-4y+8=(x+4)^2[/tex]
We're getting close. Now we need to just factor out the -4 on the left to get:
[tex]-4(y-2)=(x+4)^2[/tex]
If the standard form is -4p blah blah blah, then p has to be 1. That means that the focus is 1 unit below the vertex. The vertex is (-4, 2). p is the distance between the vertex and the focus. The focus is always on the axis of symmetry. We know that the parabola opens upside down because of the negative sign, and the parabola always wraps itself around the focus. That's why the focus is p units below the vertex. That means that the focus is located at (-4, 1).

Question 5 (4 points)
(04.02)
Determine whether the graph represents a proportional relationship. (4 points)
A graph is shown. The x-axis is labeled from 0 to 9. The y-axis is labeled from 0 to 10. Four points are shown on the graph on ordered pairs 0, 0 and 1, 3 and 2, 6 and 3, 7. These points are joined by a line. The label on the x-axis is Number of pans. The title on the y-axis is Number of cakes.
a
Yes, it is a proportional relationship because the graph goes through the origin
b
Yes, it is a proportional relationship because the graph is a straight line
c
No, it is not a proportional relationship because the graph is not a straight line
d
No, it is not a proportional relationship because the graph does not go through the origin
Answer:
C. It is not proportional because it is not a straight line.
Step-by-step explanation:
You can check to see if it is a straight line by setting up a table and ensuring that the values increase by the same amount every ordered pair.

Annika's older cousin borrowed $800 to repair her car. she will pay off the loan after 2 years by paying back the principal plus 4.5% simple interest each year. How much will she spend in interest? How much will she pay back altogether?
Answer:
The equation below is provided:
$800 = principal amount borrowed/loaned
4.5% = interest per year
2 years = terms of payment
You need to know how much is the interest per year.
$800 * 4.5% = $36
Then, multiply the amount to the terms of payment to know the total amount of the interest to be paid.
$36 * 2 years = $72
The correct answer for the amount that Anika will spend for the interest is $72.

B) functions 2 and 3 are both increasing but function 3 is increasing at a faster rate
C)functions 1 and 3 are both decreasing but function 1 is decreasing at a slower rate
D) function 1 and 3 have the same rate of change but function 1 has a greater y-intercept
Answer:
the answer is D because all the others are false, but 1 &3 both have a rate of change of 2, but 1's y-intercept is 8 and 3's y-intercept is 5

Answer:
Y=109 X=31
Step-by-step explanation:
Alright, so the angles that you have to find the values for make up 180 degrees. Since you have 71 degrees on the bottom, and according to a certain theorem I forgot about, that means that the angles you're solving for equal 109 degrees.
X= 31 because 4 x 31 = 124 and then 124 - 15 equals 109
Answer and Step-by-step explanation:
We are told that l and k are parallel (which is shown with the || symbol).
Line n therefore, is a transversal (a line that intersects two parallel lines).
We are now told to find y and x.
Since we know the lines are parallel, we can use the vertical angles theorem to say that y is equal to 4x - 15.
With angle 71, we can say that the angle that is to the left of (4x - 15) is also 71. When these two are added together, they equal 180. So let's do that.
71 + 4x - 15 = 180
Subtract 71, add 15, then divide by 4.
4x - 15 = 109
4x = 124
x = 31
31 is equal to x.
Now, we plug it into the equation so that it will equal to y.
4(31) - 15 = y
124 - 15 = y
y = 109
109 is equal to y.
We can verify this by using the supplementary angles theorem for y and 71, when 71 is above y. When y and 71 is added together, they add up to 180. So, 180 - 71 is equal to 109, which is y.
31 is equal to x.
109 is equal to y.
