Given:
The function is:
The graphs of functions 
and 
.
To find:
The function .
Solution:
We have,
The function is vertically compresses to get the graph of the function . So, the function is:
...(i)
From the given graph it is clear that the graph of the function passes through the point (3,3). So, putting 
and 
in the above function, we get
Putting 
in (i), we get
Therefore, the correct option is D.
Answer:
31.25 seconds
Step-by-step explanation:
Examine division
11.6 + 24.4 = 36 m < 50m
and 36 + 37.2 - 73.2m > 50m
50 - 36 = 14m
14 * 23.25/37.2 = 8.75 seconds
7.25 + 15.25 + 8.75 = 31.25 seconds
so it would take him 31.25 seconds to swim 50 meters.
Answer:
x=3*2 1/3
Step-by-step explanation:
In order to solve this non-linear equation, we need to move all the terms to the left side.
In our example,
- term 3, will be moved to the right side.
Notice that a term changes sign when it 'moves' from one side of the equation to the other.
(x^3 + 3) + (-3) = 57 + (-3)
We need to get rid of expression parentheses.
If there is a negative sign in front of it, each term within the expression changes sign.
Otherwise, the expression remains unchanged.
In our example, there are no negative expressions.
x^3 + 3 - 3 = 57 - 3
Answer:
It would i feel like its 132
Step-by-step explanation:
First, distribute the parenthesis:
(2x - 4) (4x - 5) = 8x - 20
\___\_/___/
| |
2x * 4x, 4 * 5
Then you add 20 to both sides
8x - 20 = 0
+20 +20
8x = 20
Then you divide both sides by 8
x = 2.5
I think I did that right... I don't quite remember what a solution set is
