Answer:
First evaluate 4^t
put x= 1 in 4^x
It's 4^1 = 4 but f(x) = 8
So we need to multiply with 2
So it's A) 2.4^x
Answer:
x = (-5,10)
Step-by-step explanation:
Solution: Let x be the height of a student in Marta's class.
The mean height of 18 students in Marta's class is 60 inches
We know that:




Therefore, the total measure of all 18 student's heights is 1080 inches
0.475 liters per minute. You need to set up a proportion.
3.705L X
----------- --------
7.8 Min 1Min
Then you cross multiply(3.705*1) and divide(3.705/7.8) and you get your X.
