The sun is about 93 million miles from the earth. express this distance in scientific notation. a) 0.93 x 10^8 b) 9.3 x 10^7 c) 9.3 x 10^6 d) 93 x 10^6

B.) 9.3 × 10^7

Step-by-step explanation:

The decimal point is to the right of the last zero, so move it to the left until you get in between the 9 and 3, so that there is only one digit to the left. That's 7 spaces, so your answer will be 9.3×10^7.

Scientific notation will always be written as a number×10 raised to a power.

The number will be between  1 and 10. In case you ever have a scenario when your decimal moves the other way, the exponent then would be negative. For now your exponent is positive.

0

step-by-step explanation:

you can not divide by 0 so 4 ÷ 0 would be 0

0 × 9999 =0

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.
