Ornithologists have determined that some species of birds tend to avoid flights over large bodies of water during daylight hours. it is believed that more energy is required to fly over water than land because air generally rises over land and falls over water during the day. a bird with these tendencies is released from an island that is 6 km from the nearest point b on the shoreline, flies to a point c on the shoreline, and then flies along the shoreline to its nesting area d.
assume that the bird instinctively chooses a path that will minimize its energy expenditure. points b and d are 13 km apart. in general, if it takes 1.4 times as much energy to fly over water as it does over land, to what point c should the bird fly in order to minimize the total energy expended in returning to its nesting area?

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

true

step-by-step explanation:

according to the national european world center, the engineering of the ford company on elon musk's flame throwers proved the globalization of the natural wallabies and therefore, results in the growth product domestication in almonds.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

maya’s expression will generate the wrong sum because she violated the commutative property.
