When x is the number of years after 1990, the world forest area (natural forest or planted stands) as a percent of land area is given by f(x)=-0.059x+31.03. In what year will the percent be 29.38% if the model is accurate?

When a rectangle is dilated, how do the perimeter and area of the rectangle change?

Write the equation in logarithmic form 8^x=64

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
