1. which two square roots are used to estimate √5? (a) √1 and √2 (b) √2 and √4 (c) √4 and √9 (d) √9 and √16 2. which two square roots are used to estimate √43? (a) √25 and √36 (b) √36 and √49 (c) √49 and √64 (d) √25 and √64 3. an esimate for -√66 is (a) -6 (b) -7 (c) -8 (d) -9 4. an estimate for √3 is round to the nearest tenth, if necessary. (a) 1 (b) 1.2 (c) 1.7 (d) 2 5. pierre is pouring concrete the foundation of a square deck covering 112 square feet. which is the best estimate of one side of the deck? round to the nearest tenth, if necessary. (a) 10 feet (b) 10.3 feet (c) 10.6 feet (d) 11 feet

1 c because √5  =  √4 and √9  3 +2 =5

2 b.

sqrt ( 36 ) * sqrt ( 49 ) = 6 * 7 = 4

3 c  sq root of - 66 = sqrt ( - 1 ) * sqrt ( 66 ) = i * 8.124

approx. 8 i

Remarq ( i ) = sqrt ( - 1 )

4 √3 c 1.7

5    sqrt ( 112 ) = 10.583   10.6 feet

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.
