Time = Distance / Speed
T = 8.5 miles/ 22 miles = 0.3863
Answer:
0.5%
Step-by-step explanation:
A shop keeper sells an article for 400
He purchases it for 402.
Therefore, loss = cost price - selling price
402 - 400 = 2
% loss =
loss/cost price x 100%
2/402 x 100%
= 200/402
=0.498
=0.5%
Part A: The exponential function is the best model for the given data. The data shows that every month the number of visitor approximately doubles from previous month. In other words the number is some base value (2, in this case) with the number of month (t) being in the exponent. This the a key characteristic of an exponential growth.
Part B: (also explained above). Every month the number of visitors approximately doubles. Starting with 5.74 at month 8, the numbers goes up by about the same amount to 12.0 at month 9. At month 10, a similar increase occurs (doubling would be 24, and the data shows 25, so this is all "aproximate"). This trend continues throughout the table.
Part C:
Month 7 will be estimated as half of month 8 (going backward):
Month 7: 5.74/2=2.87
Estimate for month 7 = 2.87 thousand visitors.
Answer:
0.575L
Step-by-step explanation:
1mL = 0.001L
We need to divide the number milliliters we are given and divide that by 1000.
575 / 1000 = 0.575
Best of Luck!
Answer:
log(x^7·y^2)
Step-by-step explanation:
The applicable rules are ...
... log(a^b) = b·log(a)
... log(ab) = log(a) +log(b)
_____
The first term, 7log(x) can be rewritten as log(x^7). Note that an exponentiation operator is needed when this is written as text.
The second term 2log(y) can be rewritten as log(y^2). These two rewrites make use of the first rule above.
Now, you have the sum ...
... log(x^7) +log(y^2)
The second rule tells you this can be rewritten as ...
... log(x^7·y^2) . . . . . seems to match the intent of the 3rd selection
