2. Solve based on the diagram below.
What is the value of angle x? How do you know (what type of angle pairs are they)?

We may conclude after answering the presented question that Therefore, the coordinates of point C are (-6, 0).

In mathematics, a coordinate is a number or combination of numbers that represents the location of a point or object in space. Coordinates are frequently used to define a point or object's position in a certain coordinate system, such as the Cartesian or polar coordinate systems. In the Cartesian coordinate system, a point is found by its distance from the origin along the x-axis and its distance from the origin along the y-axis. These distances are represented by two integers, the x-coordinate and the y-coordinate. The point's location in the plane is specified by the two coordinates.

Using the distance formula, we can find the distances AC and CB:

[tex]AC = \sqrt((x - (-8))^2 + (y - 4)^2)\\CB = \sqrt((10 - x)^2 + (-2 - y)^2)\\[/tex]

Since AC:CB = 2:1, we have:

[tex]AC/CB = 2/1\sqrt((x - (-8))^2 + (y - 4)^2) / \sqrt((10 - x)^2 + (-2 - y)^2) = 2/1\\(x - (-8))^2 + (y - 4)^2 / ((10 - x)^2 + (-2 - y)^2) = 4\\(x - (-8))^2 + (y - 4)^2 = 4((10 - x)^2 + (-2 - y)^2)\\5x^2 + 5y^2 - 116x + 20y + 340 = 0\\(x - (-8))^2 + (y - 4)^2 = r^2\\(x - (-8))^2 + (y - 4)^2 / ((10 - x)^2 + (-2 - y)^2) = 4\\[/tex]

where r is the radius of the circle.

Solving this system of equations, we get:

x = -6

y = 0

Therefore, the coordinates of point C are (-6, 0).

A, C, and D

Step-by-step explanation:

If you split the shape right along the bottom of the first part, you get two parallelograms. If you split it like you split it the first time and then split it along the side of the bottom parallelogram you get a triangle, a parallelogram, and a trapezoid. Then, because the area of a parallelogram is A=bh, you can substitute the numbers in. 5*12=60 and 6*11=66. However, this is not all, remember to add the area together! 60+66=126 so D is also true.

Using ratios, we can find the average weight of the adult bear to be 250 pounds and the angles of the triangles are 10°, 75° and 95°.

Comparing two amounts of the same unit and calculating the ratio allows us to determine how much of one quantity is included in the other. Two categories of ratios exist. The part to whole ratio is one, and the part-to-part ratio is another. The part-to-part ratio illustrates the relationship between two separate entities or groupings.

In the question given,

Ratio between birth weight and adult weight of a bear is 3:1000.

The average birth weight as given here is = 12 ounces.

Now let the average adult weight be = x

According to the ratio,

12/x = 3/1000

⇒ 3x = 12000

⇒ x = 4000 ounces.

Now 16 ounces = 1 pounds

4000 ounces

= 4000/16

= 250 pounds.

The angles are in the ratio 2:15:19

Now we know all the angles sum up to 180°

Let the angle be = x.

The equation is as follows:

2x + 15x + 19x = 180

⇒ 36x = 180

⇒ x = 180/36

⇒ x = 5

Step-by-step explanation:

Answer:

We can use the formula for compound interest to find the future value of Lyla's investment:

A = P(1 + r/n)^(nt)

where A is the future value, P is the principal (initial investment), r is the annual interest rate as a decimal, n is the number of times interest is compounded per year, and t is the time in years.

Substituting the given values, we get:

A = $2,500(1 + 0.05/2)^(2*15)

Simplifying, we get:

A = $2,500(1.025)^30

Using a calculator, we get:

A ≈ $5,016.35

Therefore, Lyla's investment will be worth approximately $5,016.35 in 15 years if interest is compounded semiannually. Rounded to the nearest dollar, the answer is $5,016.

Step-by-step explanation:

Thats what I usually use and it works

Answer:

To calculate the interest rate, we can use the formula for the present value of an annuity:

PV = PMT x [(1 - (1 + r)^(-n)) / r]

where:

PV = present value

PMT = monthly payment

r = interest rate per period

n = number of periods

In this case, we have:

PV = $12,300 (the sticker price)

PMT = $420

n = 36 (36 months)

Substituting these values into the formula, we get:

12,300 = 420 x [(1 - (1 + r)^(-36)) / r]

Simplifying this equation algebraically is not possible, so we need to use numerical methods to solve for r. One way to do this is to use a financial calculator or spreadsheet program, which can find the interest rate that makes the equation true. Using Excel's RATE function, for example, we get:

=RATE(36,-420,12300)

This gives us an interest rate of approximately 3.33% per month or 39.96% per year.

Therefore, Ella is being offered an interest rate of 3.33% per month or 39.96% per year.

Answer:

  a1 = 1875

Step-by-step explanation:

You want a1 for the geometric series that has r = 2/5, an = 120, and Sn = 3045.

The n-th term of the geometric series with first term a1 and common ratio r is ...

  an = a1·r^(n-1)

The sum of the first n terms of the geometric series is ...

  Sn = a1·(r^n -1)/(r -1)

We can use the expression for an to substitute for r^n in the sum equation:

  [tex]a_n=a_1(r^n)(r^{-1})\\\\r^n=\dfrac{a_n}{a_1r^{-1}}=\dfrac{a_nr}{a_1}\\\\S_n=a_1\dfrac{r_n-1}{r-1}=a1\dfrac{\dfrac{a_nr}{a_1}-1}{r-1}\\\\S_n=\dfrac{a_nr-a_1}{r-1}\\\\a_1=a_nr-S_n(r-1)=a_nr+(1-r)S_n\\\\a_1=(120)\dfrac{2}{5}+(1-\dfrac{2}{5})(3045)=\dfrac{2\cdot120+3\cdot3045}{5}\\\\\boxed{a_1=1875}[/tex]

Additional comment

The sum is of the first four terms:

  1875 +750 +300 +120 = 3045

We can also find this by working backward. The previous term is 5/2 times the current term. We need to find the terms that have a sum of 3045.

  120 +300 +750 +1875 +4687.5 +...

Clearly, 5 terms is too many. The sum of the first 4 terms of the backward series is 3045, so we know n=4 and the first term is 1875—the last term of our 4-term backward series.

The sum of the measures of the two angles is 180 degrees, as they are angles of a straight line. The measure of the first angle is 4x = 72 degrees, and the measure of the second angle is 6x = 108 degrees.

What is angle ?

A measure of rotation of two crossing lines or planes in mathematics is called an angle. Angles are frequently defined as degrees or radians. Two lines or splines intersect at a location, known as the apex of the angle, to produce an angle. The edges of the angle are the two lines and line segments. According to its measurement, an angle can be categorized as: An acute angle is one that ranges from 0 to 90 degrees. Right arc: an angle that is 90 degrees in length. A measureable angle intermediate 90 and 180 degrees is referred to as an obtuse angle. 180 degree angle is referred to as a straight angle.

The sum of the measures of the two angles is 180 degrees, because they are angles of a straight line. Therefore:

4x + 6x = 180

Simplifying the left-hand side, we get:

10x = 180

Dividing both sides by 10, we obtain:

x = 18

So the measure of the first angle is:

4x = 4(18) = 72 degrees

And the measure of the second angle is:

6x = 6(18) = 108 degrees

Completing the square is a strategy used in algebra to solve quadratic equations of the type ax² + bx + c = 0, where a, b, and c are constants and x is the variable. By converting the quadratic equation into a perfect square trinomial, the square roots of both sides of the equation may be used to quickly solve the problem. This is the core notion behind the completion of the square. The quadratic expression becomes a perfect square when we add and subtract a specific number from it to complete the square. Half of the x-term squared coefficient is equal to the sum of the numbers we add and remove.

The given function is f(x) = x² + 2x-12.

Now, group the x terms together:

f(x) = (x² + 2x) - 12

Between the parenthesis, add and remove the square of the x-half-coefficient: term's:

Decomposition of numbers involves breaking a number down into its constituent parts or smaller numbers that add up to the original number. This can be done in different ways depending on the purpose and context of the problem.

For example, one common way of decomposing a number is by place value. In this case, the number is broken down into its digits, which represent different powers of ten. For instance, the number 562 can be decomposed into 500 + 60 + 2.

Another way of decomposing numbers is by factoring. In this case, the number is expressed as a product of its factors. For example, the number 12 can be decomposed as 2 x 2 x 3.

Decomposing numbers is a useful skill in many areas of mathematics, including arithmetic, algebra, and geometry. It is often used to simplify problems, make computations easier, and facilitate further analysis.

To decompose 29 to make a new 10, we can break it into 9 and 20. Then, to decompose 14 to make a new 10, we can break it into 6 and 8.

So, we have:

29 + 14 = (9 + 20) + (6 + 8)

Now, we can regroup the numbers to make a new 10:

= (9 + 1) + (20 + 6) + 8

From inspection of the given right triangle, we can see that the interior angles are 45°, 45° and 90°. Therefore, this triangle is a 45-45-90 triangle.

A 45-45-90 triangle is a special right triangle where the measures of its sides are in the ratio  1 : 1 : √2.  Therefore, the formula for the ratio of the sides is b: b : b√2 where:

We have been given the hypotenuse, so:
