Carrie planted a flowering pear tree in her yard. she wants the tree to grow to be at least 30 feet tall. right now, it is 5 3 4 feet tall. if the tree grows 2 1 4 feet per year, how many years will it take for the tree to be at least 30 feet tall? write your answer as a mixed number.

7

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

i found two solutions,   n = 2 • ± √3 = ± 3.4641
