kodGreya [7K]3 years ago
5 0

Answer:

α ≈ 76°

Step-by-step explanation:

The vertices of a rectangle are right , that is 90°

Using the tangent ratio in right triangle ABC

tanα = \frac{opposite}{adjacent} = \frac{BC}{AB} = \frac{12}{3} = 4, then

α = tan^{-1} (4) ≈ 76° ( to the nearest degree )

Find the missing side length.
Dima020 [189]

Answer:

a = 4 \\ b = 2 \sqrt{2}

Seventy homes that were for sale in Tampa, Florida in Spring of 2019 were randomly selected. A regression model to predict house
Art [367]

Answer:

d. The slope of the relationship between firstfloorsquarefootage and price is moresteep for homes near the beach than elsewhere in Tampa.

Step-by-step explanation:

In this regression model, we have a positive slope. This positive slope is indicative of an increase. So to interpret this slope, we would say that the slope of the relationship that exists between the two variables (price and firstfloorsquarefootage) is steeper for the homes that are closer to the beach compared to the ones that are elsewhere. Therefore option D is our answer.

What is the product of 2x + y and 5x – y + 3?
Radda [10]

Answer:

The product of 2x + y and 5x – y + 3 is 10x^2+ 3xy + 6x - y^2 + 3y

Step-by-step explanation:

The product of the two expressions can be expressed mathematically as;

(2x +y) (5x -y +3)

To obtain the product of these expressions, we simply expand the brackets as follows;

2x(5x -y +3) + y(5x -y +3)

= 10x^2 - 2xy + 6x + 5xy - y^2 + 3y

= 10x^2- 2xy + 5xy + 6x - y^2 + 3y

= 10x^2+ 3xy + 6x - y^2 + 3y

The product of 2x + y and 5x – y + 3 is thus 10x^2+ 3xy + 6x - y^2 + 3y

Which Product will result in a cell or difference of cubes?<br> Pls do not give any joke answers
Rom4ik [11]

Answer:

(x-9)(x²+9x+81); it'll give a difference of cubes

Step-by-step explanation:

Generally, the difference of cubes formula is (a³-b³)=(a-b)(a²+ab+b²), and the third option is the only one which fits it; with "a"= x and "b"= 9.

*The sum of cubes formula is (a³+b³)=(a+b)(a²-ab+b²); for future reference.
