Answer:
sorry i don't it
Step-by-step explanation:
The first thing we should do is turn our mixed number into an improper fraction. To do this, you should multiply the whole number by the denominator, and then add the numerator and place it over the denominator.
Now our problem is 1/3+5/2. Now, we need to find the least common denominator, which is the lowest proportion where these fractions have the same denominator.
Here, we will just multiply the numerator and denominator by 2 and 3, respectively
1/3+5/2 = 2/6+15/6
Now, it is as simple as adding the numerators.
2/6+15/6=17/6
No simplification is needed, so we know this expression is equal to 17/6 or 2 5/6.
Answer: The speed is 22.2 mi/hr and woman is 8° north relative to the surface of the water.
Step-by-step explanation:
Since we have given that
Speed at which woman walks due west = 3 mi/hr
Speed at which ship moving due north = 22 mi/hr
Now it forms "Pythagorus theorem":
So, it becomes,
And the direction of the woman relative to the surface of the water is given by
Hence, the speed is 22.2 mi/hr and woman is 8° north relative to the surface of the water.
The output of the function when x=4 is 23
<h3>How to determine the output</h3>
Given the function as;
f(x)=4x+7
We are told to find f ( 4)
This explains that we should substitute the value of x as 4 in the function:
To find the value of the function at x = 4 we have:
If f(x)=4x+7
Then,
Put 4 as a replacement for x, we have:
f ( 4) = 4 ( 4) + 7
Expand the bracket
f ( 4) = 16 + 7
Add the values
f ( 4) = 23
The value of the function is 23
We can see that the value of the function when x is 4 is 23
Thus, the output of the function when x=4 is 23
The complete question is;
For each function what is the output for the given input?
For f(x)=4x+7, find f(4)
