Select the most precise and correct statement about perpendicular lines from among those that are given. Choose 1 Choose 1 (Choice A) A A B ↔ AB A, B, with, \overleftrightarrow, on top is perpendicular to C D ↔ CD C, D, with, \overleftrightarrow, on top if the two lines never meet. (Choice B) B A B ↔ AB A, B, with, \overleftrightarrow, on top is perpendicular to C D ↔ CD C, D, with, \overleftrightarrow, on top if the two lines intersect such that the measure of ∠ A O D ∠AODangle, A, O, D equals the measure of ∠ B O C ∠BOCangle, B, O, C. (Choice C) C A B ↔ AB A, B, with, \overleftrightarrow, on top is perpendicular to C D ↔ CD C, D, with, \overleftrightarrow, on top if the two lines intersect such that ∠ A O D ∠AODangle, A, O, D is a right angle.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
