<h3>This cylinder is 8 inches tall and has a volume of 200 π in³. Find the area of the cross section.</h3>
Answer: cross section = 25π in²
Step-by-step explanation:
Cylinder volume is the product of the cross section by height.
Then cross section = cylinder volume/height = 200 π in³/8in = 25π in²
Answer: 25π in²
Answer:
yes
Step-by-step explanation:
the FIRST derivative of a function tells us the slope of a tangent line to the curve at any point. if is positive, then the curve must be increasing. If is negative, then the curve must be decreasing.
the SECOND derivative gives us the slope of the slope function (in other words how fast the slope of the original function changes, and if it is accelerating up - positive - or if it is avengers down - negative).
so, the first derivative would be fully sufficient to get the answer of if the slope of the function at that point is positive or negative.
but because it is only a "if" condition and not a "if and only if" condition, the statement is still true.
there are enough cases, where the slope is positive, but the second derivative is not > 0 (usually = 0).
but if even the second derivative is positive, then, yes, the slope of the original function must be positive too.
Use the distance formula Sqrt ( (x2-x1)^2 +(y2-y1)^2)
Distance = sqrt ( (-8 - -2)^2 +(4- -4)^2)
Distance = sqrt(-6^2 + 8^2)
Distance = sqrt ( 36 + 64)
Distance = sqrt(100)
Distance = 10
The length is 10
??/? Im confused? i would help if you had more information?
Answer:
8
Step-by-step explanation:
1+1+1+1+1+1+1+1=8
take 4 ones and group them into 2 groups gives you 8
