Bank B may be a better option because the 10 percent increase is applied to the new balance each year, whereas Bank A only adds a flat 6 dollars each year.
If you put your money into Bank A, you will have to equate it as 60 + 6 = <<60+6=66>>66 dollars after one year.
If you put your money into Bank B, you will have 60 + (60 * 0.10) = 60 + 6 = <<60+(60*0.10)=66>>66 dollars after one year of the investment.
So, after one year, you will have the same amount of money in both Bank A and Bank B.

The initial value obtained using the slope-intercept relation is 3 gallons.
We need to obtain the rate of change which gives the amount of gas entering into his car per second :
Rate of change = Rise / Run
Rate of change = - 11 - 3) / (48 - 0)
Rate of change = 8/48 = 1/6 gallons
Using the slope intercept relation :
y = bx + c
b = slope ; c = initial amount of gas
Choosing any pair of (x, y) point on the table :
(0, 3)
3 = 1/6x + c
3 = 1/6(0) + c
3 = 0 + c
c = 3

For every 8 green marbles, Jen has 9 purple marbles. If she has 72 green marbles, how many purple marbles does she have?
If Jen has 72 green marbles, then she has 81 purple marbles.
If Jen has 8 green marbles for every 9 purple marbles, then the ratio of green marbles to purple marbles is 8:9.
If Jen has 72 green marbles, we can use this ratio to determine how many purple marbles she has.
Let's set up a proportion
8/9 = 72/x
where x is the number of purple marbles Jen has.
To solve for x, we can cross-multiply:
8x = 9 × 72
Multiply the terms
8x = 648
Move 8 to right hand side

One diagonal of a rhombus is 4 in shorter than the other diagonal. The area of the diagonal is 10.5 in². Find the length of the longer diagonal.
So the length of the shorter diagonal is 3 inches. The length of the longer diagonal is 7 inches.
What is the rhombus about?Let d1 and d2 be the lengths of the longer and shorter diagonals, respectively. We know that d1 = d2 + 4, and that the area of the rhombus is given by A = (d1*d2)/2 = 10.5.
Substituting d1 = d2 + 4 into the area equation, we get:
(d2+4)*d2/2 = 10.5
Multiplying both sides by 2 and simplifying, we get:
d2²+ 4d2 - 21 = 0
Using the quadratic formula, we can solve for d2:
d2 = (-4 ± [tex]\sqrt{4^2-4(-21)}[/tex]/2
d2 = (-4 ± [tex]\sqrt{100}[/tex] /2
d2 = (-4 ± 10)/2
d2 = -7 or 3
Since the length of a diagonal cannot be negative, we reject the negative solution and conclude that d2 = 3. Therefore, d1 = d2 + 4 = 7, and the length of the longer diagonal is 7 inches.

Greatest Common Factor and Factor the following polynomial by grouping ab+8a+2b+16
The greatest common factor (GCF) of the polynomial ab+8a+2b+16 is 2.
To factor the given polynomial ab + 8a + 2b + 16 by grouping, follow these steps:
1. Group the terms in pairs: (ab + 8a) + (2b + 16).
2. Factor out the Greatest Common Factor (GCF) from each group. - For the first group (ab + 8a), the GCF is "a". So, factor out "a" from the group: a(b + 8).
-For the second group (2b + 16), the GCF is "2". So, factor out "2" from the group: 2(b + 8).
3. Notice that both groups have a common factor of (b + 8). So, factor out (b + 8) from the entire expression: (b + 8)(a + 2).
Thus, the factored form of the polynomial ab + 8a + 2b + 16 by grouping is (b + 8)(a + 2).

What the pOH of a solution containing [OH-] = 4.91 x

Report your answer to at least 1 decimal place
The pOH of a solution containing [OH-] = 4.91 x 10-11 mol L-1 is 10.3. We can round the pOH to 10.3.
The pOH of a solution is the negative logarithm of the concentration of hydroxide ions (OH-) in the solution. It can be calculated using the formula:
pOH = -log[OH-]
In this case, the concentration of hydroxide ions is [OH-] = 4.91 x 10-11 mol L-1. Plugging this value into the formula, we get:
pOH = -log(4.91 x 10-11)
Using a calculator, we can find the pOH to be 10.309.
To report the answer to at least 1 decimal place, we can round the pOH to 10.3.

The required equation of the line in slope-intercept form is y = 2x + 24.
What is the slope-intercept form of a line?To find the slope-intercept form of a line, we need to use the formula: y = mx + b
Where "m" is the slope and "b" is the y-intercept.
Here,
To find the slope of the line passing through the two given points (-2,20) and (-1,22), we can use the slope formula:
m = (y₂ - y₁) / (x₁ - x₁)
where (x₁, y₂) = (-2,20) and (x₁, y₂) = (-1,22).
m = (22 - 20) / (-1 - (-2))
m = 2 / 1
m = 2
Now that we have the slope, we can use one of the given points and the slope to find the y-intercept. Let's use the point (-2,20):
y = mx + b
20 = 2(-2) + b
20 = -4 + b
b = 24

Write an equation of the parabola in intercept form that passes through (-18,72) with x-intercepts of -16 and -2
The equation of the parabola in intercept form is y = -6(x+ 16 )(x + 2).
What is Parabola?A parabola is a type of curve that is formed when a point called the focus moves along a straight line called the directrix.
In other words a parabola is defined as the set of all points in a plane that are equidistant to the focus and the directrix.
The shape of a parabola is similar to a U or a V shape, and it can either be open upwards or downwards, depending on the orientation of the curve.
The Intercept form of a parabola is given by
y = a(x - p)(x - q)
Where p and q are the x - coordinates at which the parabola crosses the x-axis (i.e, the x-intercepts).
Here we have
The parabola in intercept form that passes through (-18,72) with x-intercepts of -16 and -2
Let y = a(x-p)(x-q) is the equation of parabola
From the data, x-intercepts p = - 16 and p = -2
=> y = a(x+ 16 )(x + 2) ---- (1)
Given that the parabola passes through (-18, 72)
=> 72 = a(- 18 + 16 )(-8 + 2)
=> 72 = a(-2)(-6)
=> 72 = - 12a
=> a = - 6
Substitute a = -6 in equation (1)
=> y = -6(x+ 16 )(x + 2)
Therefore,
The equation of the parabola in intercept form is y = -6(x+ 16 )(x + 2).

Convert the rectangular coordinates to polar coordinates with r > 0 and 0 < θ (-5,0) (r, θ) = (________)
The answer is (r, θ) = (5, π).
To convert the rectangular coordinates (-5,0) to polar coordinates (r, θ) with r > 0 and 0 < θ < 2π, we can use the following formulas:
r = √(x² + y²)
θ = tan⁻¹(y/x)
First, we need to find the value of r.
r = √((-5)² + (0)²)
r = √(25 + 0)
r = 5
Next, we need to find the value of θ.
θ = tan⁻¹(0/(-5))
θ = tan⁻¹(0)
θ = 0
However, since we need 0 < θ < 2π and the point (-5,0) is in the second quadrant, we need to add π to our θ value.
θ = 0 + π
θ = π
So, the polar coordinates of the point (-5,0) are (r, θ) = (5, π).

More accurately, q, is dominated by 2. if, for all j 1, ...,S, Cij is less than or equal to Caj, and there is at least one value of j such that Cij <0. [...]
You are correct that one way to simplify a payoff table is to reject dominated or inadmissible actions.
This means identifying choices that should not be made because there are other choices that are always better.
To determine if an action q is dominated by another action r, we can compare the payoffs for each state of the world j (from 1 to S) for both actions. If the payoff Cij for action q is less than or equal to the payoff Caj for action r for all j, and there is at least one value of j for which Cij is less than Caj, then action q is dominated by action r.
In other words, if there is another action that always has a higher payoff than action q, regardless of the state of the world, then action q is dominated and should not be chosen.
By rejecting dominated actions, we can simplify the payoff table and focus on the remaining actions that have the potential to provide the highest payoffs. This can help us make more informed decisions and choose the best course of action.

To get from Boone to Charlotte, you would have to drive about 156.6 km on the shortest route. To get from Boone to Anchorage, AK, you would have to drive 4,212.7 miles. How many orders of magnitude larger is the distance from Boone to Anchorage than Boone to Charlotte? (1 mi = 1.61 km).
Answer: 1.64. To find the difference in orders of magnitude between the two distances, we first need to convert both distances to the same unit of measurement. We'll convert both distances to kilometers.
The distance from Boone to Charlotte is already in kilometers, so we don't need to do any conversion for that distance.
The distance from Boone to Anchorage is in miles, so we'll need to convert that distance to kilometers. To do this, we'll multiply the number of miles by the conversion factor 1.61 km/mi:
4,212.7 mi × 1.61 km/mi = 6,782.45 km
Now that both distances are in kilometers, we can compare them to find the difference in orders of magnitude. An order of magnitude is a factor of 10, so we'll divide the larger distance by the smaller distance and then take the base 10 logarithm of the result:
log10(6,782.45 km / 156.6 km) = log10(43.3) ≈ 1.64
So the distance from Boone to Anchorage is about 1.64 orders of magnitude larger than the distance from Boone to Charlotte.
