Answer:

Step-by-step explanation:

Remark

This is one of those questions whose answer is hidden by the sloppiness of the wording. You don't really know what the starting speed is at 129 feet. I am going to assume the submarine is constantly moving at the same speed.

Givens

d1 = 129

d2 = 229

t = 3 sec

formula

(d2 - d1) = r * t

solution

(229 - 129) = r * t

100 = r * 3

100/3 = r

33.3 feet/s = r

Caution

if you know what d = vi*t + 1/2*a * t^2 is, you could get this wrong. If you do know the formula, leave a comment below my answer.

2x + 5y = 10 <br><br> i need the slope and y-intercept
ankoles [38]
Y intercept is found by having the x value equal 0 (and vise versus for x intercept) so 5y=10 or simplified y=2
Then you have to find the x intercept (2x=10 and or x=5) then it’s just run over rise (2/5)
