Matthew is cycling of a speed of 4 meters per second . when he starts down the hill the bike wheb he starts down a hill , the bike accelerates at a rate of 0.4 m/s squared the vertical distance from the top of the hill to the bottom of the hill is 25 m is the equation d(t)=v0t+1/2 at^2 two find how long it will take mathew to ridedown the hill

Mathew will take 5 seconds to ride down the hill.

Step-by-step explanation:

Given equation is:    

Matthew is cycling of a speed of 4 meters/second. So,  

When he starts down a hill, the bike accelerates at a rate of 0.4 m/s². So,  

The vertical distance from the top of the hill to the bottom of the hill is 25 meters. So, meters.

Plugging the values into the above equation, we will get......

Using quadratic formula, we will get.......

(Negative value is ignored as the time can't be negative)

So, Mathew will take 5 seconds to ride down the hill.

answer is c

step-by-step explanation:

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
