Most bats find their way around by making high-frequency sounds, which reflect back to them off surrounding objects. A bat can emit a sound wave that travels at a speed of 343 m/s. Speed, s, can be represented by the formula, s= d/t, where d is distance, in metres, and t is the time, in seconds.
A) write an equation that can be used to determine how many metres a bat is away from an object and back.
B) how far is the bar from the object?
C) if a bat is 30 m from your house, how many seconds will it take for the bat to emit and receive a sound wave? Round your answer to the nearest hundredth of a second.

step-by-step explanation:

just keep timing it by 4.

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
