The volume of the solid is  \(\pi (e^2^-^1^)^2\)

Let us use the disc method to determine the volume of the solid that is created by rotating the area enclosed by the specified curve and lines around the x-axis.

According to the disc approach, the solid's volume can be obtained by taking the integral of \(\pi r^2dx\), where r indicates the distance between the curve and the x-axis, and dx refers to a minute change in x.

The given equation represents a curve with its limits of integration being x=6 and x=7.

The equation in question is \(y=e^(^x^-^6^)^\)

The value of the curve at a certain x corresponds to the radius of the disc.

Then, we have the integral of \(\pi (e^(^x^-^6^)^2\) dx from x=6 to x=7 represents the magnitude of the three-dimensional object.

Substitute the value, we get;

Volume =\(\pi ^ (^e^2^-^1^)^2\)

The number of bounces required for the ball's Height to be less than 10 feet is 10.

The ball will take until its height is less than 10 feet, we need to consider the successive bounces and calculate the decreasing height.

Given that each bounce loses 10% of the height of the previous bounce, we can express the height after each bounce as a fraction of the previous height.

Let's denote the initial height of the ball as H₀ = 50 feet. After the first bounce, the height will be 90% of H₀, which is 0.9 * H₀. After the second bounce, the height will be 90% of 0.9 * H₀, which is 0.9 * 0.9 * H₀. This pattern continues for subsequent bounces.

In general, after n bounces, the height can be expressed as:

Hₙ = (0.9)^n * H₀

We want to find the value of n such that Hₙ < 10 feet. Substituting the given values:

(0.9)^n * 50 < 10

Dividing both sides of the inequality by 50:

(0.9)^n < 10/50

(0.9)^n < 0.2

To solve for n, we can take the logarithm of both sides with base 0.9

log(0.9)^n < log(0.2)

n * log(0.9) < log(0.2)

Dividing both sides of the inequality by log(0.9):

n < log(0.2) / log(0.9)

Using a calculator, we can evaluate the right side of the inequality:

n < approximately 10.075

Therefore, the number of bounces required for the ball's height to be less than 10 feet is 10. Hence, after 10 bounces, the ball's height will be less than 10 feet.

1) Considering that function, we can evaluate it at x=3, i.e. find the corresponding value for f(x) when x=-3

So when we plug x=-3 into that function the corresponding y value is -15

2) Now, the other way around, we've got the y (or f(x)) value -16 let's find the corresponding value for x:

Note that looking attentively at that trinomial, we can see that this is a binomial (x+4)² or (x+4)(x+4) picking on binomial and equating to zero we can get the root. In this case, there's only value for those two roots x=-4

Answer: A=72x5

Step-by-step explanation:

The formula for the area of a rectangle is:

Area=length*width

here,

length=12x3

width=6x2

Putting these values in the formula for area gives-

Area= 12x3*6x2

simplifying the equation gives-

Area = (12*6)*(x3*x2)

we can multiply the constants and use the exponents rule to multiply the terms with power.

y^a* y^b = y^(a+b)

that provides us with-

Area = 72 *(x^(3+2))

Area = 72x5

Answer:

D, 64%

Step-by-step explanation:

To solve algebraic equations, you have to do the inverse or opposite, so because you are multiplying x by 50 on one side and x wants to be alone, you have to do the opposite which is divide by 50 to get x*1 or just x (because 50/50 equals 1) and what you do on one side of the = sign you do on the other, so 32/50 = 0.64. Then to make a percent you move the decimal to the right by 2 places and you get 64%

Answer:

D is the answer. Since the X is multiplying the 50 and then having the 32 on the other side, make X the subject by dividing both sides by 50 to make the X stand alone. Having 0.64 as your result (X=0.64), multiply 0.64 by 100 since the question demands the answer to be in percentage

So the order from left to right would be: Mode, Median, Mean.

In a positively skewed distribution, the mean is typically larger than the median, and the median is larger than the mode.

This can be illustrated in the following way:

Mean: The mean is affected by extreme values in the tail of the distribution, and will be pulled in the direction of the skew. Therefore, in a positively skewed distribution, the mean will be to the right of the median.

Median: The median is the value that separates the lower 50% of the data from the upper 50% of the data. In a positively skewed distribution, the tail of the distribution is on the right-hand side, which means that the median will be closer to the left-hand side than the mean.

Mode: The mode is the most frequent value in the distribution. In a positively skewed distribution, the mode will be the smallest value, located at the left-hand side of the distribution, while the mean and median will be to the right of it.

In the given problem, solving the problem systematically, the total cost including sales tax would be $76.94 + $5.38 = $82.32.

The cost of the oil would be 5 quarts x $10.99 per quart = $54.95.

The total cost before tax would be the cost of the oil plus the service charge: $54.95 + $21.99 = $76.94.

The sales tax on this amount would be 7% of $76.94, which is 0.07 x $76.94 = $5.38.

Therefore, the total cost including sales tax would be $76.94 + $5.38 = $82.32.

So, it would cost $82.32 to get the oil changed.

Step-by-step explanation:

The total surface area of the rotating prism is 43 ft². Therefore, option C is the correct answer.

Given that, height of the prism = 2 ft, width of the prism = 4 ft.

To find the surface area of any kind of prism we use the general formula. The total surface area of a prism is the sum of lateral surface area and area of two flat bases.

The total surface area of a Prism = (2 × Base Area) + (Base perimeter × height).

Total surface area of a prism = 2 (3 × 4) + (2.5+3+4) × 2

= 24 + 19

= 43 ft

The total surface area of the rotating prism is 43 ft². Therefore, option C is the correct answer.

First, we need to convert the volume of the juice in the jar from liters to milliliters, since the volume of the glasses is given in milliliters.

1 liter = 1000 milliliters

So, 70 liters = 70 * 1000 = 70,000 milliliters

Next, we'll divide the volume of the juice in the jar by the volume of each glass to find out how many glasses can be filled with the juice.

70,000 milliliters ÷ 150 milliliters/glass = 466.67 glasses (rounded to the nearest whole number)

Therefore, 466 glasses can be filled completely with the juice.

Finally, we can find out how much juice is left in the jar by subtracting the total volume of the juice used to fill the glasses from the volume of the juice in the jar.

70,000 milliliters - (466 glasses x 150 milliliters/glass) = 70,000 milliliters - 69900 milliliters = 800 milliliters

So, 800 milliliters of juice is left in the jar.

Based on the given information, the amount of capital this year (K1) could be something less than 25 (option c).

To determine the amount of capital this year based on the given information, we can use the investment and depreciation rates.

Let's denote the amount of capital this year as K1.

According to the information provided:

People invest 55% of income, but we don't have any information about income. Therefore, we cannot determine the exact investment amount.

10% of capital depreciates. Based on this, the capital at the beginning of this year (K1) can be calculated as follows:

K1 = K - 0.1K

= 0.9K

Since we know that the capital last year was equal to 25, we substitute K = 25 into the equation above:

K1 = 0.9 * 25

= 22.5

Therefore, based on the given information, the amount of capital this year (K1) could be something less than 25 (option c).
