Answer:

Step-by-step explanation:

Let's start by labeling the sides of the triangle ABC:

A = 12

B = x

C = 10

Using the Law of Cosines, we can write the following equation:

C² = A² + B² - 2ABcos(C)

Substituting the values we have, we get:

10² = 12² + x² - 2(12)(x)cos(10)

Simplifying, we get:

100 = 144 + x² - 24xcos(10)

Rearranging, we get:

x² - 24xcos(10) + 44 = 0

Solving for x, we get:

x = [24cos(10) ± √(576cos²(10) - 176)]/2

Calculating the values, we get:

x = [24cos(10) + √(5232)]/2 ≈ 18.3

x = [24cos(10) - √(5232)]/2 ≈ 7.7

Therefore, BC = 18.3 or BC = 7.7

Answer: The sum of the first 10 terms of the given geometric sequence is 3069.

Step-by-step explanation:

A geometric sequence is a sequence of numbers such that any two consecutive terms are in a constant ratio.

The first term of the given sequence is 3 and the common ratio is 2 (6/3 = 12/6 = 24/12 = ...).

To find the sum of the first 10 terms of a geometric sequence, we can use the formula:

S = a(1 - r^n)/(1 - r)

where a is the first term, r is the common ratio and n is the number of terms.

So for this geometric sequence:

S = 3(1 - 2^10)/(1 - 2) = 3(1 - 1024)/(-1) = 3(-1023)/(-1) = 3069

Explanation: By using the formula for the sum of a geometric sequence, the sum of the first 10 terms of the sequence was found by substituting the first term, common ratio and number of terms into the formula.

Answer:

C)  3069

Step-by-step explanation:

A geometric series is the sum of the terms of a geometric sequence.

[tex]\boxed{\begin{minipage}{7 cm}\underline{Sum of the first $n$ terms of a geometric series}\\\\$S_n=\dfrac{a(1-r^n)}{1-r}$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\ \phantom{ww}$\bullet$ $r$ is the common ratio.\\\end{minipage}}[/tex]

Given geometric sequence:

From inspection of the sequence, the first term is 3:

[tex]\implies a=3[/tex]

To find the common ratio, divide consecutive terms:

[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{6}{3}=2[/tex]

To find the sum of the first 10 terms, substitute the found values of a and r together with n=10 into the geometric series formula:

[tex]\implies S_{10}=\dfrac{3(1-2^{10})}{1-2}[/tex]

[tex]\implies S_{10}=\dfrac{3(1-1024)}{1-2}[/tex]

[tex]\implies S_{10}=\dfrac{3(-1023)}{-1}[/tex]

[tex]\implies S_{10}=\dfrac{-3069}{-1}[/tex]

[tex]\implies S_{10}=3069[/tex]

Therefore, the sum of the first 10 terms of the given geometric sequence is:

Answer: The value represented by the digit 6 is 100 times greater.

Step-by-step explanation: The digit 6 in the number 84,362 is in the tens place, whereas the digit 6 in the number 6,419 is in the thousandths place. One thousand is equal to 10 x 100, meaning that the value is 100 times greater. Hope this helps and have a great day!

The value of digit 6 in 6419 is 100 times greater than the value of the digit 6 in 84362.

Place value describes the position or place of a digit in a number. Each digit has a place in a number.

When we represent the number in general form, the position of each digit will be expanded.

Those positions start from a unit place, or we also call it one’s position. The order of place value of digits of a number of right to left is units, tens, hundreds, thousands, ten thousand, a hundred thousand, and so on.

Given that are two numbers 6419 and 84362, we need to determine that the value digit 6 in 6419 is how much times greater than the value of the digit 6 in 84362.

So, the expanded form of the numbers =

6419 = 6000 + 400 + 10 + 9

84362 = 80000 + 4000 + 300 + 60 + 2

Place values of 6 in each =

In 84362 = 60

In 6419 = 6000

∴ 6000 / 60 = 100

Hence, the value of digit 6 in 6419 is 100 times greater than the value of the digit 6 in 84362.

Answer: A. AB = BC can be proven true.

An isosceles triangle has two equal side lengths, and since the vertex angle is angle C, it means that sides AB and BC are the equal sides.

B. angle A = angle B can be proven true.

In an isosceles triangle, since the two sides are equal, the base angles are also equal.

D. segment BC = segment AC can be proven true.

In an isosceles triangle, since the two sides are equal, the base segments are also equal.

E. segment AB = segment AC can be proven true.

In an isosceles triangle, since the two sides are equal, the base segments are also equal.

C. angle B = angle C is not true.

Because the vertex angle is angle C, and it is formed by the two base segments, so it will be different than angle B and angle A.

Step-by-step explanation:

Answer:

  B, D

Step-by-step explanation:

You want to know what you can prove, given that the vertex angle of isosceles triangle ABC is angle C.

A triangle is isosceles if it has two congruent sides or two congruent angles. In either case, the angles opposite the congruent sides are congruent, and vice versa.

The vertex angle is opposite the "base" of the isosceles triangle. The sides of the vertex angle are the congruent sides, and the angles that are not the vertex angle are the congruent angles.

These sides share point B, which is not the vertex. This cannot be proven.

These are the base angles of the triangle, hence congruent. This can be proven.

These angles cannot be proven congruent using the given information. This will be true if and only if the isosceles triangle is also an equilateral triangle.

These sides share point C, which is the vertex. This can be proven.

These sides share point A, which is not the vertex. This cannot be proven.

Answer:

To determine whether the three points P, Q, and R are colinear, we can calculate the distances between pairs of points using the distance formula:

d(P,Q) = √((-8 - (-7))^2 + (4 - 6)^2 + (-11 - (-8))^2) = √((-1)^2 + (-2)^2 + (-3)^2) = √14

d(Q,R) = √((-9 - (-8))^2 + (3 - 4)^2 + (-14 - (-11))^2) = √((-1)^2 + (-1)^2 + (-3)^2) = √9

d(P,R) = √((-9 - (-7))^2 + (3 - 6)^2 + (-14 - (-8))^2) = √((-2)^2 + (-3)^2 + (-6)^2) = √19

If the three points are collinear, the distance between any two points should be a multiple of the distance between the other two points. Since √14, √9, and √19 are not multiples of each other, it can be concluded that the three points P, Q, and R are not collinear.

Sara's average speed for the entire race is

3.6 meters per second

The first 50 meters of the race is ran at a constant speed of 4.6 m/s.

Let's compute the time taken for this portion

distance = rate*time

time = distance/rate

time = 50/(4.6)

time = 10.869

It takes approximately 10.869 seconds to run the first 50 meters (at a constant speed of 4.6 m/s).

Add on the other time values from the other sections (10 and 23) to get 10.869+10+23 = 43.869

The entire 200 m race takes about 43.869 seconds.

So Sara's average speed over the entire race is about 200/43.869 = 4.559 which rounds to 4.6 m/s when rounding to one decimal place.

Given polynomials are Binomial and Trinomial.

What are polynomials?

Polynomials are algebraic expressions that consist of variables and coefficients. Variables are also sometimes called indeterminates. We can perform arithmetic operations such as addition, subtraction, multiplication, and also positive integer exponents for polynomial expressions but not division by variable. An example of a polynomial with one variable is x^2+x-12. In this example, there are three terms: x^2, x and -12.

Based on the number of terms present in the expression, it is classified as

Monomial:-A monomial is an expression which contains only one term. For an expression to be a monomial, the single term should be a non-zero term. A Examples of monomials are: 5x,3.

Binomial:-A binomial is a polynomial expression which contains exactly two terms. A binomial can be considered as a sum or difference between two or more monomials.  Examples of binomials are:

– 5x+3, 6a^4 + 17x.

Trinomial:-A trinomial is an expression which is composed of exactly three terms. A Examples of trinomial expressions are:

– 8a^4+2x+7, 4x^2 + 9x + 7.

Now,

Given polynomials are 2x ^ 2 - 2, 3x - 9,  - 3i ^ 2 - 6i + 9.

As the number of terms in first two polynomials is 2, they are binomial.

and the number of terms in third polynomial is 3, it is trinomial.

The height of the radio tower observed by the person is approximately 554.75 feet.

The tangent function is a mathematical function that maps an angle to its corresponding tangent value. It is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle in a right triangle.

We can use trigonometry to solve this problem. The angle of elevation from the window to the top of the tower is 38°, and the angle of depression from the window to the bottom of the tower is 29°. We can use these angles to form two similar right triangles, one with the tower and the window and one with the height of the tower and the difference between the height of the window and the height of the tower.

Let H be the height of the tower. Then the difference between the height of the window and the height of the tower is H - 300.

Using the tangent function, we can write:

tan(38°) = H / 300

and

tan(29°) = (H - 300) / 300

Solving for H, we find:

H = 300 * tan (38°) = 554.75 feet

So, the height of the tower is approximately 554.75 feet.
