Answer:

V = 1130.4 cm³

Step-by-step explanation:

Given that V varies jointly with r² and h then the equation relating them is

V = kr²h ← k is the constant of variation

To find k use the condition when r = 3 and h = 5 then V = 141.3 , then

141.3 = k × 3² × 5 = 45k ( divide both sides by 45 )

k = 3.14 ← note approximation for π

V = 3.14r²h ← equation of variation

When r = 6 and h = 10, then

V = 3.14 × 6² × 10 = 3.14 × 36 × 10 = 1130.4 cm³

The population of Kentucky is nearly 5.9 times that of North Dakota.

To determine how many times larger Kentucky's population is than North Dakota's population, divide Kentucky's population by North Dakota's population:

4.47 x 10^6 / 7.62 x 10^5

We can simplify the fraction by dividing both the numerator and denominator by 7.62 x 10: 4.47 x 106 / 7.62 x 105 = 5.87

5.9, rounded to the closest tenth.

As a result, the population of Kentucky is nearly 5.9 times that of North Dakota.

Therefore, Aida used a 10% cost of living adjustment to get the budgeted amount for June of Year 2.

A graph is a visual representation of data that shows the relationship between different variables or data points. Graphs are used to present complex information in an easy-to-understand way, and they can be created using a variety of formats, including bar graphs, line graphs, scatter plots, and pie charts. Graphs are commonly used in many fields, including science, mathematics, business, and economics, to help people understand and interpret data more easily.

Here,

a. To find the cost of living adjustment (COLA), we can use the formula:

COLA = (budgeted amount - actual amount) / actual amount

Substituting the given values for June, we get:

COLA = ($1,320 - $1,200) / $1,200

COLA = $120 / $1,200

COLA = 0.1 or 10%

b. To find the budgeted amount for January of Year 2, we can use the fact that the budgeted amounts for the following year reflect a 5% increase over the cost of living adjustment. Since we already know the COLA is 10%, the budgeted amount for January of Year 2 would be:

Budgeted amount = Actual amount for January x (1 + COLA + 0.05)

Substituting the given values for January, we get:

Budgeted amount = $1,150 x (1 + 0.10 + 0.05)

Budgeted amount = $1,150 x 1.15

Budgeted amount = $1,322.50

Therefore, the budgeted amount for January of Year 2 is $1,322.50.

c. Let's call the previous year's actual amount for August "A". We know that the August actual amount for Year 2 is the exact amount that Aida had budgeted for, which is:

Budgeted amount = Actual amount for August x (1 + COLA + 0.05)

$1,320 = A x (1 + 0.08)

$1,320 = A x 1.08

A = $1,222.22 (rounded to the nearest dollar)

Therefore, the previous year's actual amount for August was $1,222.

Answer:

(8,6)

Step-by-step explanation:

All you need to do is to evaluate the location of the dot:

The format of an ordered pair is (x,y).

x is the horizontal axis, going from left to right. This means that Boston is 8 to the right of the center, meaning that the x value is 8.

y is the vertical axis, going from down to up. This means that Boston is 6 up from the center, meaning that the y value is 6.

Overall, this gives you the coordinates of (8,6).

Substitute 12 and 24 for n into formula and calculate.

So, the 12th term is 63 and 24th term is 123.

The correct number line that displays the solution `x ≥ 3` would be:

 <------|------|------|------|------|------|------|------|------|------|------|------|------|------|------|------|------|------|------|------|------>

       -10    -9     -8     -7     -6     -5     -4     -3     -2     -1     0      1      2      3      4      5      6      7      8      9     10

                                   ●------------------------------------------------>

The solution `x ≥ 3` is an inequality that means x is greater than or equal to 3. To graph this inequality on the number line, we mark the point representing the value 3 with a closed circle on the number line and draw an arrow pointing to the right to indicate that all values greater than or equal to 3 satisfy the inequality.

The closed circle at 3 indicates that 3 is included in the solution set, and the arrow to the right indicates that all values greater than 3 also satisfy the inequality. Therefore, any value of x that is equal to or greater than 3 would be considered a solution to the inequality `x ≥ 3`.

It is important to note that if the inequality was `x > 3` (without the equal sign), the closed circle at 3 would be changed to an open circle, indicating that 3 is not included in the solution set, and only values greater than 3 would be considered solutions. In conclusion, the number line provided above correctly displays the solution `x ≥ 3`.

The number of people in the set C ∩ D (customers who purchased both cats and dogs) is obtained by adding the overlap of D and C (3) with the overlap of all 3 circles (1), resulting in a total of 4 individuals.

The correct answer is 4.

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to analyze the overlapping regions in the Venn diagram.

Given information:

- Circle C (cats): 15

- Circle D (dogs): 21

- Circle F (fish): 12

- Overlap of C and F: 2

- Overlap of F and D: 0

- Overlap of D and C: 3

- Overlap of all 3 circles: 1

- Number outside of circles: 14

To determine the number of people in the set C ∩ D (customers who have purchased both cats and dogs), we need to consider the overlapping region between circles C and D.

From the information given, we know that the overlap of D and C is 3. Additionally, we have the overlap of all 3 circles, which is 1. The overlap of all 3 circles includes the region where customers have purchased cats, dogs, and fish.

To calculate the number of people in the set C ∩ D, we add the overlap of D and C (3) to the overlap of all 3 circles (1). This gives us 3 + 1 = 4.

I'm not sure, I took this in 5th grade so my mind can be a little rusty, I suggest using math            _          way just to check if my answer is right :)

The slope of the tangent line is:

a = (df(x1)/dx)

The slope of the normal one is:

a' = -1/(df(x1)/dx)

For any function y = f(x), we define the slope of the tangent line at the point x as the derivative evaluated in x.

So if we want to find the slope of the tangent line at the point (x1, y1), we just need to differentiate and evaluate in x1, then the slope will be given by:

df(x1)/dx

And the normal slope is the slope of the perpendicular line, two slopes are perpendicular if the product is -1, then:

a*(df(x1)/dx) = -1

a = -1/(df(x1)/dx)

Where df/dx reffers to the derivative of f(x).

Answer:

The correct answer is B, also may be Brain??

Step-by-step explanation:

The perimeter of a rectangle can be calculated using the formula P = 2l + 2w, where l is the length and w is the width. If the length of the rectangle is 25 cm and we want the perimeter to be greater than 90 cm, we can set up an inequality to solve for the width: 2l + 2w > 90.

Substituting the value for the length gives 2 * 25 + 2w > 90, which simplifies to 50 + 2w > 90. Subtracting 50 from both sides gives 2w > 40, and dividing by 2 gives w > 20.

So the width of the rectangle must be greater than 20 cm to make the perimeter greater than 90 cm. The correct answer is B: width > 20 cm.

Answer:

i'm guessing this but not 100% sure

Step-by-step explanation:

Let w = the width

P = 2l + 2w

2w + 2(25) > 90

2w + 50 > 90

2w > 40

w > 20 cm

The different combinations of selecting 4 cars out of 10 are 210. And the different permutations of 4 cars to test drive are 5040.

What are permutations and combinations?

They are the ways of selecting things at random and in permutations is where the order of things matter whereas in combinations it does not matter in which order the objects are selected. To determine permutations and combinations formula is derived in which 'r' things are selected out of 'n' things, represented as P(n,r) and C(n,r).

The permuatations is given by the formula:

P(n,r) = n! ÷ {r! (n-r)!}

C(10,4)= 10! ÷ {4! (10 - 4)!}

          =10! ÷ {4! 6!}

          =\(\frac{10.9.8.7.6.5.4.3.2.1}{4.3.2.1.6.5.4.3.2.1}\)

          =210

P(n,r) = n! ÷ {(n-r)!}

P(10,4)= 10! ÷ {(10 - 4)!}

          =10! ÷ {6!}

          =\(\frac{10.9.8.7.6.5.4.3.2.1}{6.5.4.3.2.1}\)

You can test drive any of the 5,040 possible combinations and 2,520 possible permutations of the four vehicles on your list.

To find the number of different permutations, we use the formula nPr = n!/(n-r)!, where n is the total number of items (in this case, 10) and r is the number of items being chosen (in this case, 4).

So, the number of different permutations would be 10P4 = 10!/(10-4)! = 10x9x8x7 = 5,040.

To find the number of different combinations, we use the formula nCr = n!/r!(n-r)!.

So, the number of different combinations would be 10C4 = 10!/4!(10-4)! = 10x9x8x7/(4x3x2x1) = 2,520.
