Help please! :( "To estimate the height of a tree, Tia and Felix walk away from the tree until the angle of sight with the top and bottom of the tree is a right angle. Let h represent the height of a person's eyes and d represent the distance away from the tree. Answer parts a to c below."
(multiple parts, but only a is showing rn)

a. If the height of Tia's eyes is 1.6 m and her distance away from the tree is 2.5 m, what is the height of the tree?
The height of the tree is about ___ meters/square meters.
(insert #, then choose one).
(Type an integer or decimal rounded to the nearest hundredth as needed.)

1 is b and 2 is d

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

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:

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24
