Here you have an equation with two unknown constants, a and b, plus 2 sets of points through which the graph goes.
Second point: 96 = a(b)^2
First point: 6 = a(b)^0 Then a = 6.
With a = 6, we can now write: 96 = 6b^2. Then b^2 = 16, and b=4.
Then y =6(4)^x (answer)
Anything from 650,000 to 749,999 because they would all round to the nearest hundred thousand to 700,000
Answer:
21,000
Step-by-step explanation:
front end estimation requires you to take the front / first digit of each number in this expression and round.
if you don't know how to round, basically you take the next digit after the first one, (in 719 you take the 1) and determine if that's below or above 5. If below, then keep the original first number. If above, add one more to the first digit. If the number is five itself, it is most common to round up (so add one).
like 425 would round to just 400; and 676 would round to 700.
multiply 700 and 30
youd get 21000
