To the nearest tenth, find the approximate distance between points b and d.

a. 9.8 units
b. 8.1 units
c. 5 units
d. 3.6 units

(pic below)

Distance = 9.8 units

Step-by-step explanation:

Point B  is (-2,5) and point D is (2,-4)

LEts find the distance between these points. USe distance formula

(-2,5)  is (x1,y1)  and (2,-4) is (x2,y2)

Plug in the values and find out the distance

Distance = 9.8 units

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
