Answer:
Half a pound.
Step-by-step explanation:
To find the number of pounds he ate, multiply the fractions.
![\frac{5}{6}*\frac{3}{5} = \frac{15}{30}=\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D%2A%5Cfrac%7B3%7D%7B5%7D%20%3D%20%5Cfrac%7B15%7D%7B30%7D%3D%5Cfrac%7B1%7D%7B2%7D)
He ate 1/2 a pound.
The correct answer for the question that is being presented above is this one: "B. 6/19." Jerry has taken a random sample of students and determined the number of electives that each student in his sample took last year. There were 19 students in the sample.
I think the answer the answer/question is letter C
Answer:
A. ![f(x)=3(\frac{1}{2})^x](https://tex.z-dn.net/?f=f%28x%29%3D3%28%5Cfrac%7B1%7D%7B2%7D%29%5Ex)
Step-by-step explanation:
The options are:
![A. f(x)=3(\frac{1}{2})^x\\\\B. f(x)=\frac{1}{2}(3)^x\\\\C. f(x)=(3)^{2x}\\\\ D. f(x)=3^{(\frac{1}{2}x)}](https://tex.z-dn.net/?f=A.%20f%28x%29%3D3%28%5Cfrac%7B1%7D%7B2%7D%29%5Ex%5C%5C%5C%5CB.%20f%28x%29%3D%5Cfrac%7B1%7D%7B2%7D%283%29%5Ex%5C%5C%5C%5CC.%20f%28x%29%3D%283%29%5E%7B2x%7D%5C%5C%5C%5C%20D.%20f%28x%29%3D3%5E%7B%28%5Cfrac%7B1%7D%7B2%7Dx%29%7D)
For this exercise it is important to remember that, by definition, the Exponential parent functions have the form shown below:
![f(x) = a^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20a%5Ex)
Where "a" is the base.
There are several transformations for a function f(x), some of those transformations are shown below:
1. If
and
, then the function is stretched vertically by a factor of "b".
2. If
and
, then the function is compressed vertically by a factor of "b"
Therefore, based on the information given above, you can identify that the function that represents a vertical stretch of an Exponential function, is the one given in the Option A. This is:
![f(x)=3(\frac{1}{2})^x](https://tex.z-dn.net/?f=f%28x%29%3D3%28%5Cfrac%7B1%7D%7B2%7D%29%5Ex)
Where the factor is:
![b=3](https://tex.z-dn.net/?f=b%3D3)
And ![3>1](https://tex.z-dn.net/?f=3%3E1)
Total distance travelled = (x.a + 2x -10) miles .
How to solve such time related questions?
The key concept for solving such questions is the relationship between speed, distance and time.
The relationship between them is Distance = Speed X Time
The whole trip can be divided into two parts
Part 1 :- Speed = x mph and time = a hours
∴ Distance = x .a miles
Part 2 :- Speed = x -5mph and time = 2 hours
∴ Distance =(x-5).2 = (2x -10)miles
Total distance = (x.a + 2x -10) miles
