Which equation with exponential are true? 3^3 + 3•3

5^2 = 5•5

5^4 = 4•4•4•4•4

7•7•7•7•7•7 = 6^7

7•7•7•7•7•7 = 7^6

7•7•7•7•7•7 = 7^7

The number of revolutions of two pulleys is inversely proportional to their diameters. if a 24-inch diameter pulley making 400 revolutions per minute is belted to an 8-inch diameter pulley, find the number of revolutions per minute of the smaller pulley.

How many solutions does the nonlinear system of equations graphed bellow have?

Formulate the indicated conclusion in nontechnical terms. be sure to address the original claim. the foundation chair for a hospital claims that the mean number of filled overnight beds is over 523, and she is therefore justified starting a funding campaign to add a wing to the hospital. assuming that a hypothesis test has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.
