The statement given is true. When the bisector of an angle of a triangle bisects the opposite side, the is the triangle isosceles.

In the attached picture of ΔABC, we can see that AD is the bisector of ∠A that meets BC in D, so that BD = DC.

Now, we need to prove that AB = AC.

As construction, produce AD to E so that AD = DE, and then join CE.

So, in ΔABD and ΔECD, we have:

BD = CD

AD = ED

and ∠ADB = ∠EDC because those are vertically opposite angles.

Consequently, based on SAS congruence criterion, ΔABD ≅ ΔECD.

Thus, AB = EC and ∠BAD = ∠CED. And also, ∠BAD = ∠CAD.

For that reason, it means ∠CAD = ∠CED, and AC = EC.

Hence, AB = AC. It is proved that the triangle is isosceles.

Answer:

Step-by-step explanation:

The total length of the road is 27 miles, and since each cottage is separated from its neighbor by a distance of 1, 2, 3, 4, ..., 25, or 26 miles, the total length of the road occupied by these distances must sum to 27 miles. This is because the road connects the six cottages.

One possible distribution is:

Cottage 1 and 2 are 1 mile apart.

Cottage 3 and 4 are 2 miles apart.

Cottage 5 and 6 are 3 miles apart.

Cottages 1 and 3 are 4 miles apart.

Cottages 2 and 4 are 5 miles apart.

Cottages 3 and 5 are 6 miles apart.

Cottages 4 and 6 are 7 miles apart.

...

Cottages 1 and 6 are 25 miles apart.

Cottages 2 and 5 are 26 miles apart.

A second possible distribution can be obtained by reversing the order of the distances between the cottages. That is:

Cottages 2 and 5 are 26 miles apart.

Cottages 1 and 6 are 25 miles apart.

Cottages 4 and 6 are 7 miles apart.

Cottages 3 and 5 are 6 miles apart.

Cottages 2 and 4 are 5 miles apart.

Cottages 1 and 3 are 4 miles apart.

Cottage 5 and 6 are 3 miles apart.

Cottage 3 and 4 are 2 miles apart.

Cottage 1 and 2 are 1 mile apart.

There may be other possible distributions, but these two demonstrate that there are multiple ways to arrange the distances between the cottages while still satisfying the constraint that the distances must sum to 27 miles.

In mathematical terms, the equation e^-2.5 = h states that the exponential value of -2.5 (e^-2.5) is equal to the variable h. To convert this equation into its logarithmic form, we can take the natural logarithm of both sides of the equation. The natural logarithm, represented by the function ln, returns the power to which e must be raised to obtain a given number.

So, taking the natural logarithm of both sides of the equation, we have:

ln(e^-2.5) = ln(h)

Since ln(e^x) = x, we can simplify the left side of the equation:

ln(h) = -2.5

Thus, the logarithmic equivalent of the equation e^-2.5 = h is ln(h) = -2.5.

The logarithmic equation ln(h) = -2.5 can be interpreted as follows: the natural logarithm of h is equal to -2.5. In other words, h is the result of raising e to the power of -2.5. To find the value of h, we can use the exponential function:

h = e^-2.5

Therefore, the original equation e^-2.5 = h and the logarithmic equation ln(h) = -2.5 are mathematically equivalent and can be used interchangeably.

It is worth mentioning that logarithms are used in many areas of mathematics and science, including engineering, finance, and physics. They allow us to simplify complex calculations and to solve problems that are otherwise difficult or impossible to solve.

(a) The sum a + (a + 1) + (a + 2) + ... + (a + n - 1) is Sn = n/2 * (a + n)

It can be represented as the sum of an arithmetic series. The nth term of the series is (a + n - 1) and the first term is a.

The common difference between consecutive terms is 1. The formula to calculate the sum of an arithmetic series is:

[tex]Sn = n/2 * (2a + (n - 1)d)[/tex]

Where n stands for the number of terms, a will be the first term, and d is a common difference. By substituting the values for n, a, and d, we'll get:

Sn = n/2 * (2a + (n - 1) * 1)

Sn = n/2 * (2a + n - 1)

Sn = n/2 * (a + n)

(b) The pairs of positive integers (a,n) that will fulfill the conditions are (10,10), (15,8), and (20,6).

To find all pairs of positive integers (a,n) such that n is greater than 2 and a + (a + 1) + (a + 2) + ... + (a + n - 1) = 100, we can rearrange the formula from the above problem part (a) to solve for a:

Sn = n/2 * (a + n) = 100

a = 2 * (100/n) - n

Since a must be a positive integer, we can use trial & error to find all possible values of n that make a positive integer. Here are some of the solutions:

For n = 10, a = 10.

For n = 8, a = 15.

For n = 6, a = 20.

So the pairs of positive integers (a,n) that satisfy the conditions are (10,10), (15,8), and (20,6).

The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B

The union of two sets is a new set that contains all of the elements that are in at least one of the two sets

The intersection of two sets is a new set that contains all of the elements that are in both sets

Given data ,

From the Venn diagram , we get

n ( A ) = { 3 , 1 }

n ( B ) = { 7 , 1 }

And , n ( A ∩ B ) = { 1 }

And , the universal set n ( U ) = { 5 , 3 , 1 , 7 }

What is Cross multiplying fractions?

Cross multiply fractions by multiplying one fraction's denominator by the second fraction's numerator and then comparing the two values. The larger fraction is the one with the higher value.

Since Nathan's lawnmower uses one tank of gas to cut three one-acre lawns, it means that he can cut one one-acre lawn with 1/3 of a tank of gas. So, if he has a full tank of gas, he can cut one-acre lawns equal to the number of times 1/3 fits into a full tank. In other words, he can cut a full tank of gas divided by 1/3 of a tank of gas.

The number of one-acre lawns Nathan can cut with a full tank of gas is:

Answer: f(x) = (x+8)^(1/2) - 9 / 12

Step-by-step explanation:

To find f(x), we need to apply the steps given in the problem in the order they are presented.

First, we add 8 to the input value x. This step is represented by the term x+8.

Next, we take the square root of the result from step 2. This step is represented by the exponent (1/2) on the term x+8.

Next, we subtract 9 from the result of step 3. This step is represented by the term -9.

Finally, we divide the result of step 4 by 12. This step is represented by the division operator '/' and the denominator 12.

So f(x) is a function that takes the input x, adds 8, takes the square root, subtracts 9, and divides by 12.

Answer:

f(x) = [√(x + 8) - 9]/12

Step-by-step explanation:
The expression f(x) begins with ->

Step 1: x + 8
Step 2: √(x + 8)
Step 3: √(x + 8) - 9
Step 4: [√(x + 8) - 9]/12
