Answer:
And replacing the value of we got:
Step-by-step explanation:
For this case we have the long who represent the height 10 cm and the diameter is 6cm. So then the radius is given by:
And the surface area for a cylinder is given by this formula:
And replacing the info given we got:
And replacing the value of we got:
Answer:
x=9 y=-4
Step-by-step explanation:
1) to eliminate a variable make sure they are the same so you can cancel them out
lets eliminate x
-3 and -2 share a GCF of 6 so
2(-3x-4y=-11)
-6x-8y=-22
3(-2x-6y=6)
-6x-18y=18
-6x-8y=-22
-
-6x-18y=18
--------------------------
10y=-40
y=-4
2)substitute y as -4 in the second equation
-2x-6(-4)=6
-2x+24=6
-2x=-18
x=9
We have been given a segment AB and we are asked to find the x coordinate of the midpoint of AB.
A - x = 4
B - x = -2
the distance from A to B is;
2 units to the right from -2 to 0
4 units to the right from 0 to 4
The total distance is 2 units + 4 units = 6 units
The midpoint is 6/2 = 3 units from both A and B points.
3 points from -2 to the right is -2+3 = +1
3 points from 4 to the left side 4-3 = +1
Therefore x value for midpoint is x = 1
Answer:
i think the x and y is for x and y axis
#2) Use quotient rule
Remember for solving log equations:
#3) Derivative of tan = sec^2 = 1/cos^2
Domain of tan is [-pi/2, pi/2], only consider x values in that domain.
#4 Use Quotient rule
#9 Use double angle identity for tan
This way you can rewrite tan(pi/2) in terms of tan(pi/4).
Next use L'hopitals rule, which says the limit of indeterminate form(0/0) equals limit of quotient of derivatives of top/bottom of fraction.
Take derivative of both top part and bottom part separately, then reevaluate the limit. <span />
