Concept explainers
Projecting Birth Weight. Ultrasonic images of 29-week-old fetuses can be used to predict birth weight. One model, or formula, developed by Thurnau, is
Full-Time-Equivalent Students. Colleges accommodate students who need to take different total-credit-hour loads. They determine the number of “full-time-equivalent” students, F, using the formula
where n is the total number of credits students enroll in for a given semester.
a. Determine the number of full-time-equivalent students on a campus in which students register for 42,690 credits.
b. Solve the formula for n.

- Find the intensity of light at a depth of 12 meter if I0=14 and k=0.7. Round to two decimals.arrow_forwardThe resistance of a copper wire carrying an electrical current is directly proportional to its length and inversely proportional to its cross-sectional area. A copper wire with a diameter of 0.0126inch has a resistance of 64.9ohms per thousand feet. What length of 0.0201-inch-diameter copper wire will produce a resistance of 33.5ohms?arrow_forwardFind the unknown value. 27. y varies jointly with x and the cube root of 2. If when x=2 and z=27,y=12, find y if x=5 and z=8.arrow_forward
- The length a spring stretches varies directly with a weight placed at the end of the spring. When Meredith placed a 6-pound cantaloupe on a hanging scale, the spring stretched 2 inches. How far would the spring stretch if the cantaloupe weighed 9 pounds?arrow_forwardAn earthquake in Mexico in 1985 had and intensity level about 125, 000, 000 times the reference intensity. Find the Richter number for that earthquake.arrow_forwardThree pieces, each in the shape of a sector, are cut from the rectangular sheet of steel shown. How many Square meters are wasted after the three pieces are cut? Round the answer to the nearest tenth meter.arrow_forward

One and a half hours after Ben leaves, his sister Amanda begins jogging along the same path at 6 mi/h. How long will it be before Amanda catches up to Ben?arrow_forwardThe kinetic energy E of an object varies jointly with the object’s mass m and the square of the object’s velocity v . An object with a mass of 50 kilograms traveling at 16 meters per second has a kinetic energy of 6400 joules. What is the kinetic energy of an object with a mass of 70 kilograms traveling at 20 meters per second?arrow_forward
