Answer:
x =7.62
Step-by-step explanation:
Using Pythagoras Theorem:
a² + b² = c²
7² + 3² = x²
x² = 49 + 9
x = √58 .......in radical form
x =7.62 .....in 2 decimal form
x = 7.6 ......in nearest tenth place
Answer:

Step-by-step explanation:
To find this derivative, we will need to use the chain rule.
As there is a variable in the exponent we can use this formula:

In this case,
and 
This means that
and
respectively
This gives us 
The answer is 7
because the equation is |(3)(-2)-1|
y≥25x+2000
because the +2000 is the y intercept ( where he started) and its 25x because he gets 25 over x amount of weeks
