You are hiking along the edge of the green river (which is running straight in the area of interest). straight across from you on the opposite shore there is a particularly noticeable boulder at the edge of the river. you walk 120 feet along the shore of the river, and now the line from you to the boulder makes an angle of 35∘ with the edge of the river. you whip out your trusty scientific calculator and deduce that the width of the river at this point is:

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

thus, the first answer choice, y = sec x, is the correct one

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
