Answer:
x = 20.
Step-by-step explanation:
This is a right triangle, so by Pythagoras:
29^2 = x^2 + 21^2
x^2 = 29^2 - 21^2
x^2 = 400
x = √400
x = 20.
12-13
12-13=-1
Therefore the equation is false.
Answer:
25.15
Step-by-step explanation:
2.7 - 1.55= 1.15 + 33= 34.15 - 9= 25.15
Hi there!
The derivative of the function is the slope of the function at a specific x-value, or its instantaneous rate of change.
For example, take the equation y = x².
Using the power rule, we get:
y' = 2x
If we plug in any x-value into this equation, we can find the slope of the function at any point.
Ex:
x = 0; 2(0) = slope of 0
x = 2; 2(2) = slope of 4
The domain is talking about the "range" of the horizontal axis therefore you will be focusing on the x-intercepts.
The answer will be All non-negative real numbers less than or equal to 18
because the x-intercepts lies at 0 and 18. The answer makes sense because the furthest you can go is 18 ft and the closest you could go is 0 ft. The "all non-negative real numbers" puts a restriction on the least distance it could travel so that means that it stops at 0 ft because if you go any further, you will end up in the negatives and it clearly states "non-negative".
