Fuel oil prices averaged $0.93375 in the winter of 1998, then shot up to $1.02 in winter 1999. Calculate the additional fuel costs for a household that used 863 5/8 gallons of fuel oil during the winter of 1999.

If x/3 = 12/20, x = ?

1. If f(x)= 1/(2x + 3), then [f (1 + h) - f(1)]/h is ? 2. If f(x)=x2 + x4 and g(x)= square root (x-1), then (f o g)(x) is? 3. Identify the vertical and horizontal asymptotes of the given function y = g(x) = 3/(3x-1)

At what point does the parabola y^2-5y+9=x cross the y-axis?

Solve for x: (2.3)^x=11

The equation is not making any sense to me - nothing is comparable to the other. Consider the decomposition of the equation 19x^2 + 23x +10 6x^3 + 17x^2 - 4x â?" 3 into partial A + B + C X+3 2x-1 3x-1. How does this work????? I have 4 solutions, but I don't know how to make them work.

How do i work these x=y-1,2x=3y solving each system graphically?

When the switch is closed in the circuit below, the current begins to build up according to the equation: I=E/R[1-e^-(R/L)t] where I is current in amps, t is Time in seconds E is voltage R is resistance in ohms and L is inductance in henrys V=9volts R=10 ohms L= 20 henrys has an on/off switch a) What is the maxim

What is the area of a roof on a 30 foot by 40 foot house with 12" rake O.H. (Over Hang), 5/12 slope? Please show problem in detail.

Tony and Maria are training for a race by running all the way up and down a 700m long ski slope. They each run up the slope at different constant speeds. Coming down the slope, each runs at double his or her uphill speed. Maria reaches the top first, and immediately starts running back down, meeting Tony 70m from the top. When M

Twice as many dimes as nickels. The total value is 3.50. How many nickels are there?

Determine the vertex and axis of symmetry of each quadratic equation y=x^2-4x+1 y=1/2x^2-6x-2 y=2x^2-5

See attached file. The attached equation needs to be re-arranged such that the variable S is isolated (on the left side of the equation - eg: S=....).
