Δx (delta x) is about a secant line, a line between two points representing the rate of change between those two points. That's a "differential" (between the two points).
dx is about a tangent line to one point, representing an instantaneous rate of change. That makes it a "derivative."
Answer:
38.5ft²
Step-by-step explanation:
we know the formula for Area is
A=pi*r²
A=38.5
Another one where there's a danger of overthinking it !
The sum of ANY two integers is odd only if one is even and one is odd.
If they're both odd OR both even, then their sum is even.
So if their sum is odd, then one is odd and the other is even.
The probability is ' 1 ' (100%) .
Answer:
-5/2 is the reciprocal of -2/5, but the opposite would just be 5/2.
Step-by-step explanation:
Answer: (c) y<=-x+4
The area is shaded UNDER the boundary line, hence "<"
The boundary is plotted as solid line, hence "="
