Answer:
b
Step-by-step explanation:
what ever the number is, it has to be on THAT number. The alligator thing think of it as a arrow it points to the direction, follow the arrow
<span>The answer is 50.5.
Since X will consist of a random selection of the numbers from 1 to 100, the mean will be the middle of the set of numbers from 1 to 100 (so between 50 and 51). Imagine the set of whole numbers 1 to 100. To calculate the mean, we have to sum all the numbers, then divide by n=100. That gives 50,500/100= 50.5.</span>
Answer:
h(-8)=1 and -12
Step-by-step explanation:
In this problem, we will need to plug in "-8" for any x we see.
h(-8)=|-8+4|-3
h(-8)= |-4|-3
h(-8)=4-3
h(-8)=1
Yay! We got an answer. However, since there is an absolute value, there is another case -- if x is negative.
h(-8)=-8-4
h(-8)=-12
Answer:
64π/5 cubic units.
Step-by-step explanation:
The line x = 2 and y = x^3 intersect at the point (2 , 2^3) = (2, 8).
The required volume = volume of the cylinder with height 8 and radius 2 - the volume of shape form between the curve and the y axis when revolved about the y-axis.
Using the disk method for volumes of revolution:
Note that x = y^1/3 so:
the second volume = Integral π ((y^1/3)^2) dy between y = 0 and y = 8.
= 3/5 y^5/3 * π between 0 and 8
= 96π/5.
The required volume = π 2^2 *8 - 96π/5
= 32π - 96π/5
= 64π/5.
It begins with 3 and you have to multiply by -3 every step. This means that a6 will be equal to -729.
