Devon and Aimee are creating model volcanoes for their science project. Devon’s volcano has a radius of 3.5 inches, and a volume of approximately 89.80 cubic inches. Aimee’s volcano has the same height as Devon’s, but the radius is twice the length of the radius of Devon’s volcano. Which of the following is closest to the volume of Aimee’s volcano?

Answer:

Step-by-step explanation:

This is your position equation:

There's a whole lot of information in that equation, but what we are concerned about right now is the height of the ball after t = 3 seconds.  If this is the position of the ball at any time t, we will sub in 3 for t to find out where the ball is at 3 seconds.

which simplifies to

s(3) = -44.1 + 54 + 10 which is

s(3) = 19.9 meters

That's how high the ball is in the air at 3 seconds.

Answer:

-10

Step-by-step explanation:

h(-2) = 4(-2) -2

h(-2) = -8 -2 = -10

The solution to the problem expressed to the correct number of significant figures is, 2.13 + 1 = 3

Given that,

The solution to the problem expressed to the correct number of significant figures,

2.13 + 1 = ?

Unit is a quantity of constant magnitude which is used to measure the magnitudes of other quantities of the same manner.

Unit can be defined as the rightmost position in a number or the one's place. Here, 3 is the unit's number in the number 6713. A unit may also mean the standard units used for measurement.

You must round your answer to the same "place" when adding values as the measurement with the last significant figure that is farthest to the left.

= 2.13

= +1

= 3.13

The “1” has its last significant figure furthest to the left, so you round off the number to the “units" place. That's the last column that the measurements share.

3.13 → 3 (rounded to the "units" place)

Therefore,

The solution to the problem expressed to the correct number of significant figures is, 2.13 + 1 = 3

The equation in standard form for the given ellipse is:  \(\frac{x^2}{81} + {y^2} = 1\) To identify an equation in standard form for an ellipse with its center at the origin, a vertex at (9, 0), and a co-vertex at (0, 1),

we can use the following steps:

Step 1: Determine the values for a and b.
The distance between the center and the vertex is the value of a, which in this case is 9. The distance between the center and the co-vertex is the value of b, which in this case is 1.

Step 2: Use the values of a and b to write the equation in standard form.
The equation for an ellipse with its center at the origin can be written in standard form as:

\(\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1\)

Substituting the values of a = 9 and b = 1, the equation becomes:

\(\frac{x^2}{81} + \frac{y^2}{1} = 1\)

Simplifying further, we get:

\(\frac{x^2}{81} + {y^2} = 1\)

Therefore, the equation in standard form for the given ellipse is:

\(\frac{x^2}{81} + {y^2} = 1\)

Answer:

\(h^-^1(x)=0.5x+1.5\)

Step-by-step explanation:

Finding the inverse of a function is similar to solving for the complete opposite of a function. An easy trick to do so is the think of the resulting value (h(x)) as another variable. Solve the equation for (x) in terms of (h(x)). Finally, switch the variable and evalutator so that one has the funciton in inverse function notation.

\(h(x) = 2x - \frac{4}{3}\)

Inverse operations,

\(h(x)=2x-\frac{4}{3}\\\\h(x)+\frac{4}{3}=2x\\\\\frac{h(x)+\frac{3}{4}}{2}=x\)

Simplify,

\(0.5(h(x))+1.5=x\)

Write in inverse function notation,

\(h^-^1(x)=0.5x+1.5\)

1. Variable manufacturing overhead rate variance

The formula Actual Hours × (Actual Rate - Standard Rate) is used to calculate the variable manufacturing overhead rate variance. This variance measures the difference between the actual variable manufacturing overhead cost incurred and the standard variable manufacturing overhead cost that should have been incurred, based on the standard rate per hour.

Variable manufacturing overhead rate variance = Actual Hours × (Actual Rate - Standard Rate)

The variable manufacturing overhead rate variance provides insight into how efficiently a company is utilizing its variable manufacturing overhead resources in terms of the rate per hour. A positive variance indicates that the actual rate paid per hour for variable manufacturing overhead was higher than the standard rate, resulting in higher costs. On the other hand, a negative variance suggests that the actual rate paid per hour was lower than the standard rate, leading to cost savings.

By analyzing this variance, management can identify areas where the company may be overspending or underspending on variable manufacturing overhead and take corrective actions accordingly, such as renegotiating supplier contracts or optimizing resource allocation.

There are 4,782,905 strings with seven or more characters that can be formed from the letters in "evergreen".

What is a sequence?

A sequence is an enumerated collection of objects in which repetitions are allowed. Like a set, it contains members (also called elements, or terms).

The word "evergreen" has 9 letters. To find the number of strings with seven or more characters that can be formed from these letters, we need to count the total number of possible strings of length 7 or more, and then subtract the number of strings of length 6 or fewer.

The total number of possible strings of length 7 or more can be found by summing the number of strings of length 7, 8, 9, and so on. For each length, we can use the formula for counting the number of permutations with repetition:

\(n^r\)

where n is the number of distinct elements (in this case, 9 letters) and r is the length of the string. So the number of strings of length 7 or more is:

\(9^7 + 9^8 + 9^9 + ...\)

To subtract the number of strings of length 6 or fewer, we can sum the number of strings of length 1, 2, 3, 4, 5, or 6, and use the same formula:

\(9^1 + 9^2 + 9^3 + 9^4 + 9^5 + 9^6\)

Finally, we can subtract this sum from the first sum to get the total number of strings with seven or more characters:

\(9^7 + 9^8 + 9^9 + ... - (9^1 + 9^2 + 9^3 + 9^4 + 9^5 + 9^6)\)

This expression can be simplified using the formula for an infinite geometric series:

a/(1-r)

where a is the first term and r is the common ratio. In this case, a = 9⁷ and r = 1/9. So we get:

\(9^7/(1-1/9) - 9^1/(1-1/9)\)

= 4782969 - 9¹ * 8/9

= 4782969 - 64

= 4782905

Therefore, there are 4,782,905 strings with seven or more characters that can be formed from the letters in "evergreen".

Answer: 2

Step-by-step explanation:

5 consecutive integers with an average means the middle number will be the average since they are consecutive and even (increasing by 2/decreasing by 2). Because the middle number is 6, then the highest number will be 4 more and the lowest number will be 4 less. The consecutive numbers will be 2, 4, 6, 8, 10 and the lowest numbers is 2.

Answer:

4

Step-by-step explanation:

Consecutive numbers are numbers that increment by 1 (Ex. 1,2,3,4,5)

If the mean is 6, we know that the middle number has to be 6 and since these numbers are consecutive we can set 6 as "x" and write the following:

(x - 2, x - 1, x, x + 1, x + 2)

The equation that can be used to find h, the number of hours Aaron can rent the bike, is: 15h + 3 = 65, where h represents the number of hours.

To find the number of hours Aaron can rent the bike, we need to consider the cost per hour and the additional fee for the helmet. The cost per hour is $15, and the additional fee for the helmet is a one-time payment of $3 for the entire ride.

Let's break down the equation step by step:

Cost per hour: 15h

Additional fee for the helmet: 3

The total cost of renting the bike for h hours, including the helmet fee, should be equal to Aaron's budget, which is $65.

Therefore, the equation becomes:

15h + 3 = 65

To find the value of h, we solve the equation:

15h = 65 - 3

15h = 62

h = 62/15

h ≈ 4.13

Aaron can rent the bike for approximately 4.13 hours. Since it's not possible to rent a bike for a fraction of an hour, Aaron would round down to the nearest whole number. Therefore, he can rent the bike for 4 hours.
