Answer:
(2, -6)
Step-by-step explanation:
(a) In functional notation, you are asked for C(600).
For this, put 600 where t is in the functional notation C(t).
(b) The value multiplying 8 is 0.5 when the exponent of 0.5 is 1. That is
... t/5730 = 1
Multiplying by 5730 gives
... t = 5730
It will take 5730 years for half the Carbon 14 to be gone.
___
Or, you can recognize a fraction is 1 when its numerator is the same as its denominator. That is t/5730 = 5730/5730 = 1 when t=5730.
Answer:
The value of number is 82.5
Step-by-step explanation:
Given as :
Let The number = x
∴ 25.6 % of x = 21.12
Or, 25.6 × x = 21.12 × 100
Or, 25.6 × x = 2112
∴ x = 
i.e x = 82.5
Hence 25.6 % of 82.5 is 21.12 So , The value of number is 82.5 Answer
Answer:
(a/2) ^4 or a^4/16
Step-by-step explanation:
(8a^-3)^-4/3
split into two parts
8^ -4/3 * (a^-3)^-4/3
using the power to the power rule we can multiply the exponents
8^(-4/3) *a^(-3*-4/3)
8^ (-4/3) * a^(4)
replace 8 with 2^3
(2^3)^(-4/3) * a^(4)
using the power to the power rule we can multiply the exponents
2^(3*-4/3) * a^(4)
2 ^ (-4) * a^4
the negative exponent means it goes in the denominator if it is in the numerator
a^4/2^4
make a fraction
(a/2) ^4
or a^2/16
Answer:
Step-by-step explanation:
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
