The ratio x : y is equal to 2 : 5, and y is 80% of z. Write an equation to represent the proportional relationship between x and z.

Suppose that x and y are both differentiable functions of t and are related by the given equation. use implicit differentiation with respect to t to determine startfraction dy over dt endfraction in terms of x, y, and startfraction dx over dt endfraction .

Which fraction below is equivalent to 10/12?

The number of fish in a lake can be modeled by the exponential regression equation y=14.08 x 2.08^x where x represents the year
