Item 14 You throw a softball straight up into the air with an upward velocity of 40 feet per second. The release point is 5 feet above the ground. The function h=−16t2+40t+5 gives the height h (in feet) of the softball after t seconds.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.  

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
