A fish swims over the waterfall. The distance y (in feet) that the fish falls is given by the function y=16t2 , where t is the t

Answer:

See Explanation

Step-by-step explanation:

Given

$y = 16t^2$

The equation is incomplete. However, a possible question could be to calculate the distance of the fish at a particular time

e.g. Time, t = 4,

The distance is:

$y = 16t^2$

$y = 16 * 4^2$

$y = 16 * 16$

$y = 256ft$

Another possible question is to determine the time taken to cover a certain distance

e.g.

Distance, y = 400

This gives:

$y = 16t^2$

$400 = 16t^2$

Divide by 16

$25 = t^2$

Take square roots

$5 = t$

$t = 5\ seconds$

m∠AOC = m∠AOB + m∠BOC

We have m∠AOC = 19°, m∠AOB = 4x - 15 and m∠BOC = 2x + 10. Substitute:

19 = (4x - 15) + (2x + 10)

19 = (4x + 2x) + (-15 + 10)

19 = 6x - 5 <em>add 5 to both sides</em>

24 = 6x <em>divide both sides by 6</em>

4 = x

m∠BOC = 2x + 10 → m∠BOC = 2(4) + 10 = 8 + 10 = 18

m∠AOB = 4x - 15 → m∠AOB = 4(4) - 15 = 16 - 15 = 1

<h3>Answer: c. m∠BOC = 18°, m∠AOB = 1°</h3>
