Answer:

sin(cos⁻¹(x+1)) = √(1 - (x+1)²)

Step-by-step explanation:

The function is an exponential function of the form y = a * b^x, where "a" is the initial value and "b" is the common ratio.

Using the given table, we can see that:

- The initial value is y(0) = -2, so a = -2.

- To find the common ratio, we can divide any term by the previous term. For example:

 - b = y(1)/y(0) = (-10)/(-2) = 5

 - b = y(2)/y(1) = (-50)/(-10) = 5

 - and so on.

Since we get the same value of b for all the ratios, we can conclude that the common ratio is b = 5.

Therefore, the equation for the function shown in the table is: y = -2 * 5^x.

The triangle  DAE and FCE is congruent by the vertical angle theorem property.

What is congruency ?

Congruence of triangles is a term used in geometry to describe the relationship between two triangles that have exactly the same size and shape. In other words, if two triangles are congruent, all of their corresponding sides and angles are equal. When two triangles are congruent, they can be superimposed on each other, and all parts of one triangle will coincide with the corresponding parts of the other triangle.

The concept of congruence is essential in geometry, as it allows us to prove various theorems and make deductions about the properties of triangles. Two triangles can be shown to be congruent if any of the following conditions are met:

Side-Side-Side (SSS) Congruence: If the three sides of one triangle are equal to the three sides of another triangle, then the triangles are congruent.

Side-Angle-Side (SAS) Congruence: If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Angle-Side-Angle (ASA) Congruence: If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Angle-Angle-Side (AAS) Congruence: If two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, then the triangles are congruent.

Knowing these congruence criteria, we can use them to prove theorems and solve problems in geometry involving triangles.

The reflexive property is a fundamental concept in mathematics, and it applies to many different areas of study, including geometry. In the context of geometry, the reflexive property is related to congruence of triangles.

The reflexive property of congruence states that any geometric figure is congruent to itself. In the case of triangles, this means that any triangle is congruent to itself. In other words, every triangle is identical to itself, and all of its corresponding sides and angles are equal.

The reflexive property of triangles is used frequently in proofs and demonstrations in geometry. For example, if we want to show that a given triangle is congruent to another triangle, we can use the reflexive property to show that the two triangles are congruent to themselves. Then, we can use other methods, such as the SSS or SAS criteria, to show that the two triangles are congruent to each other.

Overall, the reflexive property is a key concept in geometry that allows us to reason about congruence and to prove various theorems and results related to triangles and other geometric figures.

5p+10 equals big 5

Answer:

p = 0.8; q = 0,6

Step-by-step explanation:

5p + 10q = 10

2p - q = 1

5p + 10q = 10

q = 2p - 1

5p + 10 ( 2p - 1 ) = 10

When adding one identical room to a pair of houses, the price increase for a house with 4000 sqft compared to a house with 1000 sqft is $150,000.

What is the basis of this problem?

We have two houses, one with a 4000 square foot floor plan and another with a 1000 square foot floor plan. Both of them are identical, and each of them is expected to receive an additional identical room. We must determine how much the price of the house with the 4000 square foot floor plan will increase compared to the house with the 1000 square foot floor plan when both of these are completed.

Let's start by identifying the amount of money needed to construct each house. The amount of money needed to construct the house with the 4000 square foot floor plan is $300,000, and the amount of money required to build the house with the 1000 square foot floor plan is $150,000.The cost of building per square foot in this case is therefore $75/sqft.

As a result, the price for a 4000 sqft house is: $75/sqft × 4000 sqft = $300,000On the other hand, the cost of constructing a 1000 sqft house is:$75/sqft × 1000 sqft = $75,000When each house gets an additional identical room, the increase in the cost of the room is $50,000. As a result, the price of the house with the 4000 square foot floor plan will increase by 4 times, or $200,000, whereas the price of the house with the 1000 square foot floor plan will increase by one, or $50,000. As a result, the price of a 4000 sqft house will be $300,000 + $200,000 = $500,000, whereas the price of a 1000 sqft house will be $150,000 + $50,000 = $200,000.

When we compare these two values, we obtain the following outcome: Suppose you add 1 identical room to a pair of houses. The two houses are identical except for square footage.

When we compare the two values, we get the following result: $500,000 - $200,000 = $300,000

Therefore, the price increase for a house with 4000 sqft compared to a house with 1000 sqft is $150,000.

The old payment is $96.60, and the new payment is $110.20. The percent increase in her new monthly payment is 14.1%.

To calculate the old payment, we multiply the original loan amount by the monthly payment per thousand, which gives us $9.66 x 55 = $531.30.

To calculate the new payment, we divide the renewed loan amount by 1000 and multiply it by the monthly payment per thousand, which gives us $11.02 x 55 = $606.10.

To calculate the percent increase, we use the formula: ((new payment - old payment) / old payment) x 100. Substituting the values, we get ((606.10 - 531.30) / 531.30) x 100 = 14.1%. Therefore, the percent increase in her new monthly payment is 14.1%.

Answer:

Using the inscribed angle theorem, we know that the measure of an inscribed angle is equal to half the measure of the central angle that intercepts the same arc. So, we need to find the central angle measure for each of the inscribed angles.

For angle a, the central angle measure is 80°, so the measure of angle a is (1/2)*80° = 40°.

For angle b, the central angle measure is 120°, so the measure of angle b is (1/2)*120° = 60°.

For angle c, the central angle measure is 40°, so the measure of angle c is (1/2)*40° = 20°.

For angle d, the central angle measure is 140°, so the measure of angle d is (1/2)*140° = 70°.

For angle e, the central angle measure is 80°, so the measure of angle e is (1/2)*80° = 40°.

For angle f, the central angle measure is 60°, so the measure of angle f is (1/2)*60° = 30°.

Therefore, the degree measures of the angles are:

a = 40°

b = 60°

c = 20°

a) The predicted GPA for a student with Verbal SAT score of 500 is 2.9805.

b) The residual for this student is -0.2805.

To calculate the predicted GPA for a student with Verbal SAT score of 500, we need to plug in the value of 500 into the regression equation:

GPA = 2.0336 + 0.0018929 × VerbalSAT

Thus, the predicted GPA for a student with Verbal SAT score of 500 is

GPA = 2.0336 + 0.0018929 × 500 = 2.9805

To calculate the residual for this student, we subtract the predicted GPA from the actual GPA

Residual = Actual GPA - Predicted GPA

Residual = 2.7 - 2.9805 = -0.2805

If you want to attend at least 4 games out of the 10 scheduled games, there are several different combinations that you can attend.

To calculate the total number of combinations, we can use the combination formula

nCr = n! / r! × (n-r)!

where n is the total number of games (10), and r is the number of games you want to attend (4).

First, let's calculate the number of combinations of attending exactly 4 games

10C4 = 10! / 4! × (10-4)! = 210

This means that there are 210 different combinations of attending exactly 4 games out of the 10 scheduled games.

Next, let's calculate the number of combinations of attending 5, 6, 7, 8, 9, or all 10 games

10C5 = 10! / 5! × (10-5)! = 252

10C6 = 10! / 6! × (10-6)! = 210

10C7 = 10! / 7! × (10-7)! = 120

10C8 = 10! / 8! × (10-8)! = 45

10C9 = 10! / 9! × (10-9)! = 10

10C10 = 10! / 10! × (10-10)! = 1

P(not odd) = number of cards that are not odd/ total number of cards

                   = 2/4 = 1/2 = .5 = 50%

The solution to the system of equations is x = 6, y = 22.

What is solution?

We can start by setting the two expressions for y equal to each other:

x² - 3x + 16 = 9x - 20

Next, we can rearrange the equation into standard quadratic form:

x² - 12x + 36 = 0

Now we can factor the quadratic:

(x - 6)² = 0

This equation has only one solution, x = 6. To find the corresponding value of y, we can substitute x = 6 into either of the original equations:

y = 6² - 3(6) + 16 = 22

Therefore, the solution to the system of equations is x = 6, y = 22.

Answer: Assuming the field is rectangular, the distance between the two corners diagonally can be calculated using the Pythagorean theorem, which states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

In this case, the length and width of the field form the two sides of the right triangle, and the diagonal is the hypotenuse.

So, using the Pythagorean theorem:

Diagonal^2 = Length^2 + Width^2

Diagonal^2 = 80^2 + 60^2

Diagonal^2 = 6400 + 3600

Diagonal^2 = 10000

Diagonal = √10000

Diagonal = 100 yards

b. The height of the golf ball 2.8 seconds after it is hit is approximately 62.72 feet.

c. It takes 4 seconds for the golf ball to hit the ground after it is hit.

a) To find the height of the golf ball at the instant it is hit, we need to evaluate the function h when t = 0.

Substituting t = 0 into the given equation, we get:

h = -16(0)² + 64(0) = 0

Therefore, the height of the golf ball at the instant it is hit is 0 feet.

b) To find the height of the golf ball 2.8 seconds after it is hit, we need to evaluate the function h when t = 2.8.

Substituting t = 2.8 into the given equation, we get:

h = -16(2.8)² + 64(2.8) ≈ 62.72

Therefore, the height of the golf ball 2.8 seconds after it is hit is approximately 62.72 feet.

c) To find how long it takes the ball to hit the ground after it is hit, we need to find the value of t when the height is 0.

Setting h = 0 in the given equation, we get:

0 = -16t² + 64t

0 = t(-16t + 64)

t = 0 or t = 4

Since the golf ball was hit upwards, we are only interested in the positive value of t, which is t = 4.
