The measure of angle θ is 45 degrees.

What is the value of angle θ?

The measure of angle θ is calculated by applying trigonometry ratio as follows;

SOH CAH TOA

SOH = sin θ = opposite /hypothenuse side

TOA = tan θ = opposite side / adjacent side

CAH = cos θ = adjacent side / hypothenuse side

The height and the adjacent side is given, so the value of θ is calculated as follows;

tan θ = (206 - 7 ) / (199)

if you are asked to find the value of the 100th term of a sequence, would you use the explicit formula for that sequence or the recursive formula?

Answers

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference.

We know that,

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference.

The explicit formula for any arithmetic series is given by the formula,

a_n = a_1 + (n-1)d

where d is the difference and a₁ is the first term of the sequence.

The major distinction between recursive and explicit formulas is that a recursive formula returns the value of a particular term depending on the preceding term, whereas an explicit formula returns the value of a given term based on its location.

When the value of the first term and the common difference is known then an explicit formula is used, while the recursive formula will be used when the value of the previous value is known and the value of the common difference is known.

Answer:

  (a) ∠7 = 47°. Angles 5 and 7 are vertical angles, hence congruent.

  (b) 47 +(2x -5) = 180

  (c) 69

Step-by-step explanation:

Given angles identified as ∠5, ∠6, ∠7 where two lines cross, and the measure of ∠5 as 47°, you want the measure of ∠7, and an equation and solution when ∠6 is (2x-5).

(a) Vertical angles

Angles that share a vertex and are formed from opposite rays are "vertical angles." They are congruent.

Angles 5 and 7 are vertical angles, so the measure of angle 7 is the same as the measure of angle 5.

  ∠7 = 47°

(b) Supplementary angles

Angles that form a linear pair are supplementary. This means the sum of angles 5 and 6 is 180°.

  ∠5 +∠6 = 180°

  47° +(2x -5)° = 180°

What is Pythagorean theorem?

In Mathematics and Geometry, Pythagorean's theorem is modeled or represented by the following mathematical equation (formula):

x² + y² = z²

Where:

x, y, and z represents the length of sides or side lengths of any right-angled triangle.

How to determine the value of x?

First of all, we would determine length of sides or side lengths of the opposite side of the ight-angled triangle as follows;

12.5² + y² = 19.5²

156.25 + y² = 380.25

y² = 224 cm.

y = √224 cm

Now, we can determine value of x;

x² = (√224)² + (5.5)²

x² = 224 + 30.25

x = 15.9 cm.

Answers

The measure of the angle m∠3 of the triangle is m∠3 = 150°

Given data ,

Let the triangle be represented as ΔABC

Now , the measures of the angles are

m∠1 = ( 3x + 12 )°

m∠2 = ( 3x + 18 )°

m∠3 = ( 7x + 10 )°

m∠3 = 180° - ( m∠1  + m∠2 )

Now , for a triangle , the total angles = 180°

So , m∠1 + m∠2 = m∠3

On simplifying , we get

( 3x + 12 ) + ( 3x + 18 ) = ( 7x + 10 )

6x + 30 = 7x + 10

Subtracting 6x on both sides , we get

x + 10 = 30

Subtracting 10 on both sides , we get

The spinner shown has eight congruent sections. The spinner is spun 320 times. What is a reasonable prediction for the number of times the spinner will land on an odd number?

Answers

It is fair to assume that the spinner will land on an odd number 160 times.

The likelihood of landing on any one of the eight congruent portions of the spinner is 1/8. This information allows us to reasonably forecast the frequency with which the spinner will fall on an odd number.

The likelihood of landing on an odd number is 4/8 or 1/2 since the spinner has four odd numbers (1, 3, 5, and 7) and four even numbers (2, 4, 6, and 8). Thus, we may anticipate that the spinner will land on an odd number on average 50% of the time.

If the spinner is spun 320 times, we would expect it to land on an odd number about half of those times, or approximately:

(1/2) x 320 = 160

Therefore, the probability that the spinner will fall on an odd number 160 times is fair.

A reasonable prediction for the number of times the spinner will land on an odd number is 160.

We have,

Since the spinner has eight congruent sections, each odd number (1, 3, 5, and 7) appears once on the spinner, and there are a total of four odd numbers.

Since the spinner is spun 320 times, we can expect each section of the spinner to be landed on equally, on average.

Therefore, the expected number of times the spinner will land on any one section is 320/8 = 40.

Since each odd number appears once on the spinner, we can expect the spinner to land on an odd number 4 times in every 8 spins, or once in every 2 spins.

Therefore, the expected number of times the spinner will land on an odd number in 320 spins is approximately 320/2 = 160.

Thus,

A reasonable prediction for the number of times the spinner will land on an odd number is 160.

A ladder measures 6 feet. If the top of the ladder is placed 4 feet up on a wall, how many feet from the base of the wall is the bottom of the ladder?

Answers

We can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

In this case, the ladder, the wall, and the ground form a right triangle, with the ladder being the hypotenuse. Let x be the distance from the base of the wall to the bottom of the ladder. Then we have:

x^2 + 4^2 = 6^2

Simplifying the equation:

x^2 + 16 = 36

Subtracting 16 from both sides:

x^2 = 20

Taking the square root of both sides:

x = sqrt(20)

Simplifying:

x = 2sqrt(5)

Therefore, the bottom of the ladder is approximately 4.5 feet from the base of the wall.

Olga Semargl's medical care bills for a recent illness were $4,620. Her major medical policy did not
cover $312 of the bill. Olga's policy had a coinsurance feature that paid 80% of all covered expenses
over a $500 deductible. What was the amount paid by the major medical policy?

Answers

The amount paid by the major medical policy is $3,046.40.

First, we need to calculate the covered expenses before the coinsurance feature comes into play. Since Olga's major medical policy did not cover $312 of the bill, the covered expenses will be:

Covered expenses = Total bill - Amount not covered

Covered expenses = $4,620 - $312

Covered expenses = $4,308

Next, we need to calculate the amount of the covered expenses that is subject to the coinsurance feature. Since Olga's policy has a $500 deductible, the covered expenses subject to coinsurance will be:

Covered expenses subject to coinsurance = Covered expenses - Deductible

Covered expenses subject to coinsurance = $4,308 - $500

Covered expenses subject to coinsurance = $3,808

The coinsurance feature pays 80% of the covered expenses subject to coinsurance, so the amount paid by the major medical policy will be:

Amount paid = Coinsurance rate x Covered expenses subject to coinsurance

Amount paid = 0.8 x $3,808

Amount paid = $3,046.40

Therefore, the amount paid by the major medical policy is $3,046.40.

Find the standard form of the equation of the hyperbola with the given characteristics.
Vertices:

(7, −12)

Answers

The standard form of the equation of the hyperbola is

[(y + 6)²/4] - [(x - 3)²/16] = 1.08

We have,

To find the standard form of the equation of a hyperbola, we need to know the locations of the vertices and the foci.

In this case, we are given the coordinates of the vertices, but we need to find the foci. However, we are also given that the hyperbola passes through the point (7, −12), which will allow us to find the foci.

First, let's find the center of the hyperbola.

Since the vertices have the same x-coordinate of 3, the center must be the point (3, −6), which is the midpoint of the two vertices.

Next, we can find the distance between the center and one of the vertices. Using the distance formula, we get:

d = √[(3 - 3)² + (-8 - (-6))²] = 2

Since the vertices are vertically aligned, we know that the distance from the center to each vertex is the same.

Therefore, the distance from the center to each vertex is also 2.

We can now use the Pythagorean theorem to find the distance from the center to each focus, which we will call c.

We know that c² = a² + b², where a is half the distance between the vertices (in this case, a = 2), and b is half the distance between the foci.

We want to solve for b.

Since the hyperbola passes through the point (7, −12), we know that the distance from this point to each focus is constant and equal to the distance from this point to the center of the hyperbola.

Using the distance formula, we can set up the following equation:

√[(7 - 3)² + (-12 - (-6))²] = sqrt[(7 - 3)^²+ (-12 - (-8))²] + b

Simplifying this equation, we get:

2 √(37) = 2 √(20) + b

b = √(37) - √(20)

Now that we have the values of a and b, we can write the standard form of the equation of the hyperbola:

[(y + 6)²/4] - [(x - 3)²/16] = 1 + [(√(37) - √(20))²/16]

Simplifying, we get:

[(y + 6)²/4] - [(x - 3)²/16] = 1.08

Therefore,

The standard form of the equation of the hyperbola is

[(y + 6)²/4] - [(x - 3)²/16] = 1.08
