A tile in the shape of a regular hexagon is shown. How many tiles will be required to cover a rectangular counter top area 3.4' by 3'? (Remember: One inch equals 2.54 centimeters.)
Solve.A faucet is used to add water to a large bottle that already contained some water. After it has been filling for 5 seconds, the gauge on the bottle indicates that it contains 19 ounces of water. After it has been filling for 13 seconds, the gauge indicates the bottle contains 43 ounces of water. Let y be the amount of water in the bottle x seconds after the faucet was turned on. Write a linear equation that relates the amount of water in the bottle,y, to the time x.
A. y = 
x + 
B. y = 3x + 4
C. y = -3x + 34
D. y = 3x + 30
Express the function in the form f(x) = a(x - h)2 + k and indicate the vertex.f(x) = x2 - 11x + 9
