You need to flip the shapes over the x-axis and move over -8 to 0
The answer is negative two (-2)
-7 * -4 = 28, then divide 14 - 2 to the 2nd power, 14 - 2 to the 2nd power is 10, now divide, 10 by 28 and u get 2.8 then simplify and u get (-2).
Answer:
Step-by-step explanation:
We have been given that a jar is filled with 7 red marbles and 3 green marbles. We are asked to find the probability of pulling out 2 green marbles in a row if the marbles are not replaced after they're pulled out.
The probability of pulling 1st green marble will be number of green marbles divided by total marbles.
Since the marble is not replaced, so number of total green marbles will be 1 and total marbles will be 9.
Probability of getting green marble for another time will be .
To find probability of getting 2 green marbles in a row would be product of both probabilities as:
Therefore, our required probability would be .
These are hexagonal prisms. If you count the sides, there are six of them. Hexagons have 6 sides
Answer:
Step-by-step explanation:
The missing equation is:
Suppose f = nonnegative function whose first derivative is within (a,b) and it is continuous, Then the area of the surface generated is revolved about the x-axis:
The area of the surface revolution is:
So; if for
Then; substituting a with c and b with d; f(x) also with g(y) and dx with dy;
Then;
SInce;
; Then the statement is false.
Provided that the semicircle isn't on interval.
Then, the solid generated by the revolution about the x-axis is a sphere.
However, the surface is well defined and the statement is false.
