Acertain metal has a coefficient of linear expansion of 2.00 × 10-5 k-1. it has been kept in a laboratory oven at 325°c for a long time. it is now removed from the oven and placed in a freezer at ‐145°c. after it has reached freezer temperature, the percent change in its density during this process is closest to a) +2.90%. b) ‐2.90%. c) +2.74%. d) ‐2.74%. e) it is not possible to tell without knowing the mass and original volume of the metal.

Jasmine is diving off a 3-meter springboard. her height in meters above the water when she is x meters horizontally from the end of the board is approximated by the equation h=-x^2+3x+3. what is the maximum height jasmine will reach on her dive?

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
