Use the Laws of Logarithms to combine the expression.(1/2)log2(6) − 2 log2(7)

On the same set of axes, graph the image of MNOP for a dilation with center (0, 0) and scale factor 2. Use coordinate geometry and the definition of similar polygons to prove that MNOP is similar... more

(x^2/(x^2+x-56)) = I tried solving this question by dividing the numerator by the denominator and I got 1+ (56-x/(x^2+x-56). I simplified the denominator and I got 1+(56-x/(x+8)(x-7) ). Lastly, I... more

Th e arcs in the photo at the right appear to be paths of stars rotating about the North Star. To produce this eff ect, the photographer set a camera on a tripod and left the shutter open for an... more

A quadratic function f is given.f(x) = −4x2 − 20x + 4(a)Express f in vertex form.(b) Find the vertex and x- and y-intercepts of f. (If an answer does not exist, enter DNE.)vertex:X intercept... more

Consider rolling a pair of fair dice a single time. For a given roll, consider the value shown on each of the dice. For each of the following pairs of events, tell whether they are disjoint,... more

Find the equations of all lines that are tangent to the graph of the function f(x) = x ^ 2 + 1 and pass through the point P(1,0). Be careful: this point is not on the graph of f.

a graph of f(x)=1/4|cos(pi(x-1/2))-3| Can you tell me all that is happening here including the transformations, reflection, stretch/compression, shifts, etc, and the vertex and x/y values, and how... more

Part of a rollercoaster course precedes point A(0,35) (point F precedes point A) point F cannot go any further than 45m from point A (in the y-axis). The gradient at point A is zero. the slope... more

exponential 2 ref points. (0,1) and (1,b) when b^x formula ab^(x-h)+k ref point (0,1) is (h, a+k) Ref point 2 is (h+1,ab+k). How is this formula derived ?
