hello
from the question given, the dog walker charges a flat rate of $6 and an extra $30 per hour.
we can write out an equation in function notation
let the number of hours be represented by x
now we can proceed to solve the cost of the walk for 45 minutes
now we can input the value into the equation and know the cost for 45 minutes walk
from the calculation above, the cost of 45 minutes walk will cost $28.5

Here we know that Margie is standing on a bridge looking at the river. She throws a rock over the bridge with an initial velocity of 60 ft/sec. The height, h, of the rock at the rime t seconds after it was thrown can be modeled by the equation:
To calculate how long will it take for the rock to reach the surface of the water, we need to set . So:
Given that time can't be negative, we just choose the positive value. Therefore, <em>it will take 4.70 seconds for the rock to reach the surface water.</em>
