A tent is 3 m wide and 2 m tall in the middle, what is the angle of elevation, for the side of the tent, to the nearest degree? Assume the two sides are symmetrical.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

7 is the median   7.875 is the mean

step-by-step explanation:

3,4,5,6,8,11,13,13

the answer is "add 2y and y"

step-by-step explanation:

you need to collect the like terms first.

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
