An MBDA official investigated an accident in Roman highway. They saw a 200- feet-long skid mark which was produced from the time driver stepped on the car break to the time it fully stopped. During... more

A circle has center (6, 2) and radius 9. Find all values of such that (x, - 1) is a point on the circle.

If the point (2, 5) is the center of a circle and the point (6, 4) lies on that circle, what is the circle's radius?

The volume of an expanding sphere is increasing at a rate of 12 𝑓𝑡3/s . When the volume of the sphere is 36𝜋 𝑓𝑡3 , how fast in 𝑓𝑡2/s is the surface area increasing? Hint: 𝑉 = 4/3 (𝜋𝑟 3) and 𝑆 = 4𝜋𝑟 2

(x^4 -2x^3 +x -4) divided by x^2 -3

Suppose f ,g , and h are functions of a single variable with domains ( − ∞ , 1 ) ,[ 0 , π ] , and ( − 1 , 1 ) , respectively. What is the domain of the function F ( x , y ) = f ( x ) − g ( x ) h (... more

Part of a cross-country skier's path can be described with the vector function r = <2 + 6t + 2 cos(t), (15 − t)(1 − sin(t))> for 0 ≤ t ≤ 15 minutes, with x and y measured in meters. The... more

An environmental study indicates that the average daily level P of a certain pollutant in the air in parts per million can be modeled by the equation P= 0.25*square root of (0.5n^2+5n+25), where... more
