(1.1•10^-5)(3 •10^-2)a. 4.1 • 10 ^-7b. 4.1 • 10^10 c. 3.3 • 10^-7d. 3.3 • 10^10

C. 3.3 • 10^-7

Step-by-step explanation:

(1.1•10^-5)(3 •10^-2)

Multiply the numbers out front of the powers of ten, then add the exponents on the powers of 10

1.1 * 3   * 10 ^(-5+-2)

3.3 ^ (-7)

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.
