To find the volume of the solid obtained by rotating the region under the curve over the interval [4, 7] about the x-axis, we can use the method of cylindrical shells.

The formula for the volume of a solid generated by rotating a curve f(x) about the x-axis, over an interval [a, b], is given by:

V = ∫[a, b] 2πx * f(x) * dx

In this case, the interval is [4, 7], so we need to evaluate the integral:

V = ∫[4, 7] 2πx * f(x) * dx

To find the function f(x), we need the equation of the curve. Unfortunately, you haven't provided the equation of the curve. If you can provide the equation of the curve, I will be able to help you further by calculating the integral and finding the volume.

Please provide the equation of the curve so that I can assist you in finding the volume of the solid.

This a question about perimeter and equation, let's see how to solve that:

The perimeter of a rectangle is the sum of its 4 sides. In this case, we know that the perimeter is 118. We can do an equation with these datas:

\(\boxed{AB + BC + CD + DA = 118}\)

We also know other informations: the side AB is equal to \(4y+3\) and de side BC is equal to 3y. In a recltangle, parallels sides have the same value. So, the side CD is equal to \(4y+3\) and the side DA is equal to 3y.

Now, we have these datas:

\(AB + BC + CD + DA = 118\\\\AB = CD = 4y + 3\\BC = DA = 3y\)

Let's do and solve an equation:

\(AB + BC + CD + DA = 118\\\\4y+3 + 3y + 4y+3 + 3y = 118\\14y + 6 = 118\\14y = 118 - 6\\14y = 112\\y = \frac{112}{14} \\y = 8\)

So, the value of y is 8. Let's replace the value of y in the side AB:

\(4y + 3\\4\times 8 + 3 = 35\)

Therefore, the length of side AB is 35.

The correct option is (d)

He wrote commutative instead of associative in step 2.

According to the commutative property, a mathematical principle, the product of a multiplication does not depend on the order in which the numbers are multiplied.

Commutative property:  a+b = b+a

Associative property: (a+b) + = a+(b+c)

Now consider the provided expression.

(6.2 − 1.6) − 4.4 + 7.8

Step 1:

(6.2 − 1.6) − 4.4 + 7.8

Step 2 Use Associative property

6.2 + (−1.6 − 4.4) + 7.8

Step 3: Simplify

6.2 − 6 + 7.8

Step 4: Use commutative property

The solution of the given logarithmic equation is x = 28.1

Here we have the logarithmic equation:

4*ln(x - 8) = 12

And we want to solve this for x.

Remember the relations:

\(ln(e^x) = x\\e^{ln(x)} = x\)

First, we divide both sides by 4:

\(ln(x - 8) = 12/4 = 3\)

Then, if we apply the exponential equation to both sides of our equation, we get:

\(e^{ln(x - 8)} = e^{3}\\\\x - 8 = e^3\\\\x = e^3 + 8 = 28.1\)

The number of customers entered the store during the first six hours is 432 .

Given,

S(t) = 2t³ - 48t² + 288t

0≤ t≤ 12

L(t) = -80 + 4400/t² -14t + 55

0≤ t≤ 12

Now,

Shoppers entered in the store during first six hours.

Time variable is 6.

Thus substitute t = 6 ,

S(t) = 2t³ - 48t² + 288t

S(6) = 2(6)³ - 48(6)² + 288(6)

Simplifying further by cubing and squaring the terms ,

S(6) = 216*2 - 48 * 36 +1728

Answer:

B) adjacent angles are supplementary, not complementary

Step-by-step explanation:

Adjacent angles in a parallelogram are not complementary.

No, the consecutive angles of a parallelogram exist not complementary angles. The consecutive angles of a parallelogram exist also directed to the adjacent angles that exist as supplementary, that is, they add up to 180°.

The adjacent angles of a parallelogram exist those angles that exist placed subsequent to each other in order. Observe the subsequent parallelogram to visit the 4 pairs of adjacent angles. These angles stand also comprehended as consecutive angles of a parallelogram. Each pair of adjacent angles here adds up to 180°. The 4 pairs of adjacent angles in the parallelogram exist, ∠P and ∠Q, ∠Q and ∠R, ∠R and ∠S, and ∠S and ∠P.

1)The expression 4x^2-16x+12/x^2-9 is undefined when the denominator, x^2-9, equals zero because division by zero is undefined.

x^2-9 equals zero when x equals 3 or x equals -3. Therefore, the expression is undefined at x = 3 and x = -3. In all other cases, the expression is defined.

2) The given expression is:

(5-2x)/(x+2) + x^2/(x^2-4) - 5

To simplify this expression, we need to first find the LCD (least common denominator) of the two fractions. The denominator of the first fraction is x+2, and the denominator of the second fraction is x^2-4, which can be factored as (x+2)(x-2). So the LCD is (x+2)(x-2). Now we can rewrite the expression with this common denominator:

[(5-2x)(x-2) + x^2(x+2) - 5(x+2)(x-2)] / [(x+2)(x-2)]

Expanding the brackets and simplifying, we get:

(-x^3 - 3x^2 - 3x + 5) / [(x+2)(x-2)]

This expression is undefined when the denominator, (x+2)(x-2), equals zero because division by zero is undefined.

(x+2)(x-2) equals zero when x equals -2 or x equals 2. Therefore, the expression is undefined at x = -2 and x = 2. In all other cases, the expression is defined.

The number of different materials that Kat can choose from are 6.

Given that:-

Kat is ordering customized shoes online. She can choose from one material, one color and one sole.

Number of different colors available = 18

Number of different types of soles available = 12

Total number of options available to Kat for her shoes = 1296

We have to find the number of different materials that Kat can choose from.

Let the  number of different materials that Kat can choose from be x.

We know that,

Number of different materials that Kat can choose from = (Number of different colors available)*(Number of different types of soles available)*(number of different materials)

Hence, by simple multiplication, we can write,

1296 = 18*12*x

1296 = 216x

The hydrogen ion concentration [H+] for tomatoes with a pH of 4.86 is 1.67 x 10^-5 moles/liter.

The pH of a solution is defined as the negative logarithm (base 10) of the hydrogen ion concentration [H+]. Mathematically, pH = -log[H+].

Rearranging the equation, we get [H+] = 10^(-pH).

Substituting the given pH of 4.86 into the equation, we get [H+] = 10^(-4.86).

Evaluating the expression, we get [H+] = 1.67 x 10^-5 moles/liter. Therefore, the hydrogen ion concentration for tomatoes with a pH of 4.86 is 1.67 x 10^-5 moles/liter.

Mean is used to measure the center of a set of values. It is good for summarizing values which are generally pretty similar to each other.

Mean is more usually referred to as the average. It is calculated by adding up all of the values and dividing by the total number of values. It is a good way for summarizing the center of values which are commonly very similar to each other.

The mean is the most often used measure of central tendency since it uses all values in the data set to give us an average. For data from skewed distributions, the median is better than the mean because it is not influenced by large values.

gain (%)=

100×[selling price(S.P)–cost price(S.P)] / cost price

15= 100×[S.P−4100]/4100

S.P=41×15+4100

Based on the information provided, ETS is an abbreviation for these three terms (Error, Trend, and Season). Following that, Exponential Smoothing Methods for an ETS system can be described, with the details specified in a smoothing style.

=> As should be obvious, combining Error, Trend, and Season on any occasion in three distinct ways yields a plethora of combinations.

=> The trend depicts the overall layout of the time. It communicates with the data's drawn-out model — its tendency.

=> The seasonal section displays the types associated with anticipated events. Finally, the error component explains what the season and trend components do not. The error is due to the disparity between the first data and the combination of trend and seasonality. As a result, if we crystallize all three parts, we will have the first data back.

=> It has a counted substance conduct when the period of seasonal swings remains constant.

=> We can label our model as ETS (M,A,M).
