In The Following Problems, Name The Method By Identifying Whether The Integral Can Be Evaluated Using

Answers

Answer 1

Integration by parts or using partial fractions is overkill. Both can be done with simple substitutions.

For the first integral, take y = x + 1 and dy = dx.

\(\displaystyle \int \frac2{(x+1)^2} \, dx = \int \frac2{y^2} \, dy = -\frac2y + C \\\\ = -\frac2{x+1} + C\)

For the second integral, use the same substitution.

\(\displaystyle \int \frac{x-1}{(x+1)^2} \, dx = \int \frac{(y-1)-1}{y^2} \, dy = \int \left(\frac1y - \frac2{y^2}\right) \, dy = \ln|y| + \frac2y + C \\\\ = \ln|x+1| + \frac2{x+1} + C\)

Given the circle below with secants JKL and NML, find the length of JK. Round to the nearest tenth if

Answers

Using the Intersecting secants theorem, the length of JK in the given diagram is 17

Intersecting secants theorem: Calculating the length of of JK

From the question, we are to determine the length of JK in the given diagram.

The diagram shows a circle with intersecting secants.

From the Intersecting secants theorem which states that "if two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment".

Then,

We can write that

JK × KL = NM × ML

From the given diagram,

KL = 14

NM = 14

ML = 17

Substituting the values

JK × 14 = 14 × 17

JK = (14 × 17) / 14

JK = 17

Hence, the length of JK is 17

The slope of the line according to the graph will be -2 which is denoted by m.

What is slope?

The ratio of how much y grows as x grows by a certain amount is known as slope of line. The slope of a line tells  how steep it is, or how much y rises as x rises. Everywhere along the line, the slope remains constant (the same).

What is slope formaulae?

the slope of line is denoted by m.

              m=(y2-y1)/(x2-x1)

The points on the graph are (x1,y1)=(3/2,0)

                                                (x2,y2)=(0,3)

According to the formulae,

We have proven that △ABD ≅ △CBD based on the given information and the SAS congruence criterion.

To prove that △ABD ≅ △CBD, we can use the SAS (Side-Angle-Side) congruence criterion.

Given:

∠BDA ≅ ∠BDC (Both are right angles)

D is the midpoint of AC¯¯¯¯¯

AB¯¯¯¯¯ ≅ BC¯¯¯¯¯

BD¯¯¯¯¯ bisects ∠B

Proof:

Since D is the midpoint of AC¯¯¯¯¯, we have AD ≅ CD by the definition of a midpoint.

AB¯¯¯¯¯ ≅ BC¯¯¯¯¯ (Given)

BD¯¯¯¯¯ is a common side for both triangles.

∠BDA ≅ ∠BDC (Given)

To apply the SAS congruence criterion, we need to show that one pair of corresponding sides and the included angle are congruent in both triangles.

AD ≅ CD (Side) - This is true as D is the midpoint of AC¯¯¯¯¯.

∠BDA ≅ ∠BDC (Included Angle) - Both are right angles.

Using digits 1to 9 fill in the boxes once write largest and smallest absolute value. Then find the decimal equivalent.

Answers

The decimal equivalent of the largest Absolute value, 987654321, is 987,654,321.  the largest absolute value is 987,654,321 and the smallest absolute value is 123,456,789.

The largest and smallest absolute values using the digits 1 to 9, we need to arrange them in a way that maximizes or minimizes the resulting number. Let's consider the boxes as placeholders for the digits.

To determine the largest absolute value:

We place the digit 9 in the leftmost box, as it is the largest digit among 1 to 9. Then we arrange the remaining digits, 8, 7, 6, 5, 4, 3, 2, and 1, from largest to smallest in the remaining boxes. This gives us the number 987654321, which is the largest possible number using the given digits. Therefore, the largest absolute value is 987654321.

To determine the smallest absolute value:

We place the digit 1 in the leftmost box, as it is the smallest digit among 1 to 9. Then we arrange the remaining digits, 2, 3, 4, 5, 6, 7, 8, and 9, from smallest to largest in the remaining boxes. This gives us the number 123456789, which is the smallest possible number using the given digits. Therefore, the smallest absolute value is 123456789.

To find the decimal equivalent of these numbers, we simply read the digits from left to right. The decimal equivalent of the largest absolute value, 987654321, is 987,654,321. The decimal equivalent of the smallest absolute value, 123456789, is 123,456,789.

Thus, the largest absolute value is 987,654,321 and the smallest absolute value is 123,456,789.

The perimeter of a triangle is the sum of the length of the three sides of the triangle.

Let the shortest side be represented with s.

Given that x=8 and y=5 the rectangle below, find the perimeter (P) and Area(A) of the rectangle

Answers

Answer:

Perimeter: 26

Area: 40

Step-by-step explanation:

Since we can't see the image, I'll just assume that X and Y are Length and Width?

In that case, the mathematical formula for finding (P) would be:

P = 2( L + W )

This means the the perimeter is: Two times the (Length plus Width)

If we input the two numbers, the equation is now:

P = 2 ( 8 + 5 )

When you multiply these values, the final answer for perimeter will be 26.

----------------------------------------------------------------------------------------------------------

To find the (A) of a rectangle, you must multiply the ( Length) and (Width).

An ant colony is built by 200 ants. The number of ants triples each week. How many ants will be in the colony at the end of the eighth week?

Answers

To solve this problem, we need to use the formula for exponential growth:

N = N0 * 3^t

where N is the final number of ants, N0 is the initial number of ants, 3 is the rate of growth (since the number of ants triples each week), and t is the number of weeks.

We are given that there are initially 200 ants, so N0 = 200. We want to find N at the end of 8 weeks, so t = 8. Substituting these values into the formula, we get:

N = 200 * 3^8

N = 200 * 6561

N = 1,312,200

Therefore, at the end of the eighth week, there will be 1,312,200 ants in the colony.

3. A pound of flour costs $12. How many ounces of flour can be purchased for $3.30?

Answers

With a pound of flour costing $12 and considering that there are 16 ounces in a pound, the cost per ounce is $0.75. Thus, for $3.30, you can purchase 4.4 ounces of flour.

To find out how many ounces of flour can be purchased for $3.30, we need to determine the cost of one ounce of flour.

Given that a pound of flour costs $12, we know that there are 16 ounces in a pound (since there are 16 ounces in 1 pound). So, the cost of one ounce of flour can be calculated as:

Cost of one ounce of flour = Cost of one pound of flour / Number of ounces in one pound

Cost of one ounce of flour = $12 / 16 ounces

Cost of one ounce of flour = $0.75

Therefore, the cost of one ounce of flour is $0.75.

To determine how many ounces of flour can be purchased for $3.30, we divide the total amount of money by the cost of one ounce of flour:

Number of ounces of flour = Total money / Cost of one ounce of flour

Number of ounces of flour = $3.30 / $0.75

Number of ounces of flour ≈ 4.4 ounce

Therefore, for $3.30, approximately 4.4 ounces of flour can be purchased.

In summary, with the given cost of $12 for a pound of flour, and knowing that there are 16 ounces in a pound, we find that one ounce of flour costs $0.75. Thus, for $3.30, approximately 4.4 ounces of flour can be purchased.
