Multiply or divide as indicated watching significant digits. (a) (6.5 ✕ 1018 m)(5.3 ✕ 10-10 m)

(b) (5.2 ✕ 10-7 m)/(3.2 ✕ 10-12 s)

(c) (8.5 ✕ 10-4 km)(1.3 ✕ 10-3 km)

(d) (6.6 ✕ 105 kg)/(3.3 ✕ 103 m3)

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

answer: 0.26

i used the calculator on google

the bolded word " farsighted" could be replaced with visionary.

if your equation is in the form ax2 + bx + c, you can find the maximum by using the equation:

max = c - (b2 / 4a).

the first step is to determine whether your equation gives a maximum or minimum.

-x2 + 4x - 2.     thats an example hope it
