Answer:
1. <em>L = 3D +59</em>
2. 158 miles
Step-by-step explanation:
For the second part:
Since each day 3 miles of the road is being added, we can simply multiply the number 33 by 3, getting 99. If the road started with 59 miles, we need to add 59 to 99, getting 158 miles.
Answer:
Do in calculator simple answer
The value of sin(2x) is 
Explanation:
Given that 
The formula for 
is 
Since, 
Also, it is given that
Thus, 
and 
To find the hypotenuse, let us use the pythagoras theorem,
Now, we can find the value of sin x and cos x.
Now, substituting these values in the formula for sin 2x, we get,
Thus, the value of sin(2x) is
Because like terms you add or subtract together to make it easier to do the problem. just like you do with whole numbers. you add an subtract to make the answer simpler.
