Johnathan and Cecelia are peering at a streetlamp several feet above their heads. Johnathan is standing 10 feet away from the base of the lamppost, and he sees the lamp at an angle of x degrees in elevation. Cecelia is standing 4 feet further from the base than Johnathan, and she sees the lamp at an angle of y degrees less in elevation than Johnathan does. Lamp Cecelia Johnathan ground 4 feet 10 feet © 2017 FlipSwitch. Created using GeoGebra. Which equation could be used to find the height of the streetlamp from the perspective of each friend (assuming Johnathan and Cecelia are the same height)? tan xm) tan(kuy) 14 tan
A team of astronauts is preparing a mission to the moon. The pull of gravity on the moon is different than on Earth. On the moon, things weigh of what they weigh on Earth. For this mission, each astronaut will bring x pounds of food and y pounds of gear. Which inequality correctly compares the weight of the supplies on the moon to the weight of the supplies on Earth, given that a represents the number of astronauts going on the mission? xa yaxatya
The profit of a start-up company over a one-year period can be modeled by the function Px)2 +10x+24, where x is time in months and profit is calculated in thousands (In other words, a profit of 1 is equal to $1,000) Part A: During what month did the company earn the most profit? Part B: Part A is asking for the fblankL of the function in the given interval. Part C: At what month did the company break even (have no profit and no debt)? Part D: Part C is asking for the Iblank of the function in the given interval Choose one answer for Part A one answer for Part B, one answer for Part C, and one answer for Part D.

The polarity (positivity or negativity) of the voltage of an LED lightbulb fluctuates over time according to the function f(x) = 2 cos x, where x is time in hours. Part A: At what time is the lowest voltage reached for 0 <xS 4 Part B: At what time is the voltage neutral (0) for 0 <x 4? Select one answer for Part A and one answer for Part B B:플 □서 B: A: □A:플
Shea wants to install fencing on a portion of her yard, which is formed by two square patches of grass. The area of the first patch of grass is 5x square feet, and one side of that patch is a feet long. The area of the second patch is Ty square feet, and one side of that patch is b feet long. Shea wants to install a 40-foot fence that will stretch along the front of the yard, where a +b the front of the yard. 7y 5x O2017 FlipSwitch. Created using GeoGebra.
