GIVEN: Emma started biking to the coffee shop traveling , after some time the bike got a flat so Emma walked the rest of the way, traveling If the total trip to the coffee shop took and it was away.
TO FIND: how long did Emma travel at each speed.
SOLUTION:
Let the distance traveled by Emma through bike is
Total time taken when traveled by bike
Distance traveled through feet
Total time taken when traveled by feet
Now,
Total time taken
Distance traveled through feet
Hence distance traveled using bike is and by feet is
Answer:, x ≠ -1/4
Explanation:We are given that:
f (x) = 4x + 1
g(x) = x² - 5
We want to find the value of (g/f)(x). This means that we will simply divide g(x) by f(x) as follows:
Now, we should note that any function is undefined if its denominator is equal to zero.
This means that for our current function:
4x + 1 cannot be equal to zero
4x + 1 = 0
4x = -1
x = -1/4
This means that the value of x cannot be -1/4, otherwise, our function would be undefined.
Based on the above, the last option is the correct one.
Hope this helps :)
Answer:
2.60 gr
Step-by-step explanation:
We need to consider the function where Po is the initial substance k is the rate of decay and t is the time
We know that and at the 7 th year P(t) is 7
This means
We solve for k
