Ok so, based on the graph lets say that x = seconds and y = depth of dolphin. the interception in both points is when they are at 0 i.e when x is equals 0 and y equals 0. So At 0 seconds, the dolphin is 42 feet below the surface. So we say that x = 0, y = -42 and then the y intercepts = -42 so the point of interception is(0 (seconds),-42(depth of the dolphin)) When the clock says it's 14 seconds, the dolphin is even with the surface (0 below the surface this time). So we say that x = 14, y = 0. In this case The x intercept = 14 (14,0). But we need to calculate The slope with the formula= (y2 - y1)/(x2 - x1) = 42/14 = 3. Therefore, the formula for this line is y = 3x - 42.
10q equals 7p because of the difference

This can be solved with Pythagreon Thereom.

Follow the steps below. A and B are the heaight an base, C is they hypotonuese.

Answer:
Here, V(r) is the function dependent on the variable r whch is the radius of any sphere.
By plugging different values of r in the formula. one can find the volume associated with it.
Here, V(r) represents the volume of the sphere when the radius is equal to r.
