How does the radius of a positive and negative ion compare to a neutral atom?
Answers
A neutral atom contains equal amount of proton and electron.
A negative ion contains extra electrons hence there is additional outer shell so it is expected that the radius is bigger than that of a neutral atom.
While a positive ion contains less electron so there is less outer shell so the radius is smaller than that of a neutral atom.
Arranging the radius in increasing order:
positive ion, neutral atom, negative ion

You select a card at random from the cards that make up the word replacement. On each card, there is one letter. Without replacing the card, you choose a second card. Find the probability of choosing a vowel and then not a vowel
Answers
4 of them are vowels : e, a, e, e
7 of them are not vowels : r, p, l, c, m, n, t
The probability of getting a vowel the first try is 4/11.
The probability of getting something that is not a vowel is 7/10. The denominator is one less because the vowel card is not replaced, meaning there is one less card to choose from.
Multiply.

Find the number of hours it would take to drive 510 miles at 55 mph. Round to the nearest tenth of an hour. i THINK ITS 9.3 BUT IM NOT SURE?
Answers
hope this helps.
Answer: It would take 9.3 hours to take 510 miles.
Step-by-step explanation: We are given to find the number of hours it would take to drive 510 miles at 55 mph.
We will be using the UNITARY method to solve the given problem.
According to the given information, we have
Number of hours taken to drive 55 miles = 1 hour.
So, number of hours taken to drive 1 mile will be
[tex]\dfrac{1}{55}~\textup{hour}.[/tex]
Therefore, the number of hours it would take to drive 510 miles is given by
[tex]\dfrac{1}{55}\times510=\dfrac{102}{11}=9.27~\textup{hour}.[/tex]
Rounding to nearest tenth of an hour, we get
9.27 hour ≈ 9.3 hour.
Thus, it would take 9.3 hours to take 510 miles.

Explain the difference between exponential growth and exponential decay
Answers
[tex]y = a^{x} , a\ \textgreater \ 1[/tex]
Exponential decay is the function
[tex]y = a^{x} , 0\ \textless \ a\ \textless \ 1[/tex]
So, the basic difference is that in growth the base is more than 1, and in decay the base is more than 0 but less than 1.
Final answer:
Exponential growth occurs when a population increases at an increasing rate, whereas exponential decay involves a decrease at a rate proportional to the current size. Logistic growth, adding the concept of carrying capacity, more accurately reflects natural populations with initial exponential increase followed by a plateau as resources become limited.
Explanation:
The key difference between exponential growth and exponential decay lies in the direction and rate at which a quantity changes over time. Exponential growth occurs when a population grows at an increasing rate as time passes, often depicted as a J-shaped curve, whereas exponential decay describes a process of decrease at a rate proportional to the current value, leading to a rapid reduction in size or quantity over time.
In the context of biology and population growth, exponential growth describes how populations can grow dramatically when there are no limits to resources or space. This type of growth can be formalized as a mathematical model where the population after n time periods has increased by a factor of 2n when the base growth rate is 2. In natural populations, this is idealized and does not usually last long as resources become depleted and other limiting factors come into play. On the other hand, exponential decay in biology might refer to the rapid loss of a population due to harsh conditions, lack of resources, or other negative impacts.

We have the b at 25m, but to find the h we need to drop an altitude or apothem down that is perpendicular to the base (90°). Now we have to do some trig to determine that h.
Since we're given that AB is 40m, and <B is 80°, we can set up a SOH-CAH-TOA equation:
The hypotenuse = 40m, and our height is opposite <B, therefore sin (80) = h/40,
h = 40 × sin (80) = 40 × 0.985 = 39.39m
Now, a = 1/2bh = 1/2 (25m)(39.4m)

The graph of parent function f(x) move up b unit for f(x)+b.
The graph of parent function f(x) move down b unit for f(x)-b.
The graph of parent function f(x) move left b unit for f(x+b).
The graph of parent function f(x) move right b unit for f(x-b).
Since, the graph of the parent function moves down, Therefore Option Option B and D are incorrect.

suppose the correlation coefficient between the number of the college students in a city and the number of city buses is 0.89. which statement must be true?
Answers
Answer:
Step-by-step explanation:
Given that the correlation coefficient between the number of college students in a city and the number of city buses is 0.89.
We find that correlation coefficient is a measure of linear association between two variables.
When the absolute value of correlation coefficient is near 1, there is strong correlation. If correlation has a positive sign, there is a posiitive association between the two variables.
Here the correlation coefficient is positive and also near 1. Thus there is a strong linear correlation between the two variables.
Or whenever there is an increase in one variable there will be an increase in other variable also.

- do we need to be on the left or the right side of the line to find points that satisfy the equation?
- is the line itself included or not
To start with the second question, since y has to be greater than and not equal, the line itself is NOT included in the solution area. This means the correct answer has to have a dashed line.
The general way to know on which side of the line you have to be, is to fill in one easy point and see if the equation holds. Let's fill in (0,0), (but any point will do).
you get: 0 > 1 - 3*0, which is NOT true. So (0,0) is in an area that is not our solution. The top-right picture is therefore not the answer.
What remains is the bottom-right picture, that is the correct shaded area. All points in the shaded area satisfy the equation.

South of the White House in Washington, D.C., is the President’s Park South, or the Ellipse, which hosts events such as the White House Garden Tours. The Ellipse is 880 ft from north to south and 1057 ft from east to west. Write an equation in standard form for the Ellipse, centered at the origin.
Note: If any values of a2 or b2 are greater than 1,000, include the comma.
Answers
(x^2/a^2)+(y^2/b^2)=1
Where a is one half of one axis, and b is one half of the other.
The problem states that one axis is 1057 ft, and the other is 880 ft, so divide these values by 2 and square them. This results in:
(x^2/279,312.25)+(y^2/193,600)=1
For verification, if you have a graphing calculator, solve for y, set the size of the window so it should perfectly fit the ellipse, and check (it does)
Given the dimensions of the Ellipse, the major axis is the east-west distance (1057 ft) and the minor axis is the north-south distance (880 ft). Taking half these lengths as 'a' and 'b' respectively, the equation of the ellipse in standard form centered at the origin is (x^2/(528.5^2)) + (y^2/(440^2)) = 1.
Explanation:The given dimensions of the Ellipse represent the lengths of the major and minor axes. In an ellipse centered at the origin, the equation in standard form is given by:
(x^2/a^2) + (y^2/b^2) = 1
where 'a' is half the length of the major axis and 'b' is half the length of the minor axis. Here, since the measurement from east to west (1057 ft) is greater than the measurement from north to south (880 ft), 'a' will have a value of 1057/2 and 'b' will have a value of 880/2. Consequently, the ellipse equation would be:
(x^2/(528.5^2)) + (y^2/(440^2)) = 1

The width of a rectangle is 2m less than the length. the area is 48m squared. find the dimensions
Answers
Then the width, W = L - 2
A = LW
48 = L(L - 2)
48 = L^2 - 2L
L^2 - 2L - 48 = 0
(L - 8)(L + 6) = 0
L - 8 = 0 or L + 6 = -6
L = 8 or L = -6
Since the length of a rectangle cannot be a negative number,
we discard the -6.
The length is 8m
The width is 2 m less than the length, so the width is 6 m.
The length of the rectangle is 8m and the width is 6m
This question involves the area of a rectangle and we can use the formula to solve this problem.
Data given;
A = 48m^2w = (L - 2)mAreaThe area of a rectangle is given as
[tex]A = L * W[/tex]
l = lengthw = widthsubstitute the values and solve
[tex]A = lw\\48 = L * ( L - 2)\\48 = l^2 -2l\\l^2 -2l - 48 = 0[/tex]
solve this quadratic equation to find the length
a = 1, b = -2, c = -48
[tex]l = \frac{-b+-\sqrt{b^2 - 4ac} }{2a} \\l = \frac{-(-2)+-\sqrt{(-2)^2-4*1*(-48)} }{2*1} \\l = 8[/tex]
Taking only the positive value of l, l = 8
but we also know that
[tex]w = l -2\\w = 8 -2\\w= 6[/tex]
from the above, the length of the rectangle is 8m and the width is 6m
