Answer:
D) 6.79 x 10^7
Step-by-step explanation:
Company D has the greatest revenue because it is multiplying by 10 to the power of 7 which is the same as multiplying by 10 seven times. The least revenue is company C because it is only multiplying by 10 to the power of 4 which is the same as multiplying by 10 4 times.
6.8 x 10^7 = 68,000,000
9 x 10^4 = 90,000
68,000,000 - 90,000 = 67,910,000.
Convert this back into standard form to get 6.79 x 10^7
Answer:
35 seconds
Step-by-step explanation:
At negative values he is inside the volcano, when he reaches 0 he will be at the top of the volcano
At 35 seconds, the elevation is 0, so he is at the top of the volcano
Answer:
x = 31.2
Step-by-step explanation:
x - 19.7 = -4.1
x = 15.6 --- add 19.7 to both sides to get rid of -19.7
x = 31.2 --- multiply both sides by 2 to get rid of
Answer:
This is easy -- it's just a list of steps. At this level, the problems are pretty simple.
Let's just do one, then I'll write out the list of steps for you.
Find the inverse of f( x ) = -( 1 / 3 )x + 1
STEP 1: Stick a "y" in for the "f(x)" guy:
y = -( 1 / 3 )x + 1
STEP 2: Switch the x and y
( because every (x, y) has a (y, x) partner! ):
x = -( 1 / 3 )y + 1
STEP 3: Solve for y:
x = -( 1 / 3 )y + 1 ... multiply by 3 to ditch the fraction ... 3x = -y + 3 ... ditch the +3 ... subtract 3 from both sides ... 3x - 3 = -y ... multiply by -1 ... -3x + 3 = y ... y = -3x + 3
STEP 4: Stick in the inverse notation, f^( -1 )( x )
f^( -1 )( x ) = -3x + 3
