Answer:

First and last options are the correct answers

Step-by-step explanation:

$d = \sqrt {(x_2-x_1)^2 + (y_2-y_1)^2}$

$d = \sqrt {(x_1-x_2)^2 + (y_1-y_2)^2}$

Find the equation of the line through the points (-2,5) and (3,-10). Give your answer in slope-intercept form.

Brilliant_brown [7]

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{-10 - 5}{3 - (-2)} = \frac{-15}{3 + 2} = \frac{-15}{5} = -3$

y - y₁ = m(x - x₁)
y - 5 = -3(x - (-2))
y - 5 = -3(x + 2)
y - 5 = -3(x) - 3(2)
y - 5 = -3x - 6
+ 5 + 5
y = -3x - 1

Choose the correct algebraic expression: two plus the product of six and a number

mel-nik [20]

2 + 6n because product means multiply so when you combine 6 and n, it ultimately means you’re going to multiply them together

A flagpole is at the top of a building. 300 feet from the base of the building, the angle of elevation of the top of the pole is

Grace [21]

Answer: We can use tangent here to find the length of the flagpole

First, find the length of the building + the flag pole

tan 32 = x/300

x=300tan32=187.460805573

(length of building + flagpole)

find length of building

tan 30 = x/300

x=173.205080757

subtract

187.460805573-173.205080757=14.255724816

round, length of flagpole = 14 feet

Calculate the size of each interior angle of a regular polygon with 14 sides

Ierofanga [76]

Answer:

154.285

Step-by-step explanation:

The sum of the interior angles of a 14-gon = (14-2)*180 = 2,160 degrees. There are 14 vertexes (vertices) for a 14-gon. It is 'regular' so all these angles are equal. By dividing 2160 (sum of all angles) by 14 (total amount of angles) we can see how much each angle is worth. So the interior angle of each is 154.285 degrees.
